Ryan, I honestly believe you are the only person _on earth_ who would feel an earthquake in a dry dock and think "Oh my God, I hope it's not the Amagi all over again!"
This story was told to me by my room mate in Spain in about 1973... (I can't attest to the accuracy of it) It happened back in the 60's... he was on a submarine (USS Archerfish, SS-311, I think). They were in a drydock in Bremerton, WA He claimed he was down on the floor of the dry dock, underneath the sub when the earthquake struck (in Alaska, maybe?). He said the boat was bouncing on the keel blocks. He also said that some of the yardbirds later told him that he came out from under the boat at a dead run, ran to the closest wall, and scaled it like a spider. The difference between a 46,000 ton battleship and a 3,000 ton submarine, sitting on the blocks.
It has nothing to do with the total tonnage. It's the type of soil, strength of the earthquake, weight distribution of the ship and placment of the blocks. Ryan's comment about the strength of the drydock foundation reducing the shaking is without merit, while there are earthquake resistant structures it isn't about strength. Depth, distance, soil types, and direction of the fault all have substantial effect on the feel of a quake. But generally speaking an energy of 4.5 is just a tiny shake that many people won't even notice if conditions aren't just so, about like a large truck driving by a few feet away. You really won't see damage or unsecured stuff falling over below about 5.5 6.0 is where you start to get notable structural damages to brittle structures and stuff falling off of shelves, 6.5 can be a big deal with some expensive repairs, 7 and up is a major emergency.
Speaking of soil density differences, are your damage estimates based on West coast quakes? The east coast contains much more bedrock which tends to carry the waves farther afield. i.e. the New Madrid quake, magnitude 7.2- 8.2, with a IV Mercalli scale or higher was felt over a 600K square km area, while the 1906 San Francisco quake, magnitude 7.8 magnitude, quake VII Mercalli scale was only felt in a 6.2 K square mile radius. Though, granted the San Francisco quake damage was greatly influenced by the type of fill that underlaid the port areas as well as the fact that SF was much more densely populated at the time with less infrastructure to damage.
The 1964 Alaska earthquake caused houseboats in Lake Union, Seattle to bounce around, a floating theatre in Green Lake to fall apart, and the Space Needle restaurant to stop rotating - so shaking a dry dock at Bremerton sounds reasonable.
Back in 1987 When the Whittier Narrows (SoCal) earthquake hit, 5.9 magnitude, the USS Leahy CG 16 was in drydock #3 at LBNSY. I was in the coordination center between drydocks 2 & 3. The building moved around really good and longer for the "average" earthquakes we have around here. A couple of my friends, a sheetmetal supervisor and his leader were on the 04 level of the Leahy and they said they could see the bow of the ship twisting. They just hugged each other until it was over. The inspectors found that the Leahy had moved 1.5" on her keel blocks.
That's pretty impressive that the weight of the ship on the blocks causes it to twist with the earth beneath it! Of course, the hull is meant to flex and twist to absorb the force of incoming waves, so it naturally should do so.
Magnitude matters. Every full point is a 10x increase in the power involved. Had this been an 7 or an 8 I'm sure the ship would have slipped some, or worse. That'd be a hell of a mess. About the only thing you could do is flood the dock and get her back up on the blocks to look for major damage. Short of a broken keel it would probably be fixable.
@@BlackEpyon I had a friend who was on pier 3 when it hit and he said the pier was rocking so badly he wasn't able to walk. 🙂 When the Oliver Hazard Perry class frigates were in drydock, they also had telephone poles mounted horizontally from the side of the drydock to the sides of the ship. They also placed a couple keel blocks on the fantail and forecastle, I guess for added weight.
@@chrismaverick9828 in that situation you'd better hope that the repairs being done will still allow the dock to be flooded, otherwise you're gonna have to get some strong cranes in
I think she'll easily make it past 20 years. She's better built than USS Texas and look at the fact USS Texas is still here even after decades of mistakes and neglect. BB62 has the benefits of "best practices" for caring for it as learned from USS Texas's list of "what not to do". As long as the maintenance is kept up, she'll serve as a memorial and educational tool for decades and generations.
@@kman-mi7suI believe the battleships will serve again all four of them including North Carolina Alabama Massachusetts we're all serve again I believe that I believe in Battleships
@@Isaiah-53-777hell, I'd reactivate them just for fun if I were King! It's nice to have some Battleships in your back pocket. Good thing I'm not King!
Doesn't matter how solid a foundation there is. Acceleration rate of the tectonic plate slipping is going to move anything attached to it. Combined with the direction of the acceleration is what ultimately decides whether a ship is going to get knocked off its blocks or not.
@@ricinro That's true. However, I don't think a dry dock would do too well having been designed for earth quakes. I could be wrong, but the math involved is too much to do on a whim. [ While writing this I looked but could not find 1920s concrete listed nor if they used rebar. I looked in all 3 of my engineers bible's. ] Now I'm kind of wanting to do the math...
an earthquake while on a ship that is in water is quite interesting. we had one, one morning at muster at long beach naval station. the ship and all of us on it were stationary, but you could see the pier, and vehicles on the pier moving back and forth about 10 feet. strangest looking thing to watch.
Kinda on subject but the ocean liner Olympic actually felt an earthquake in 1929 while sailing near the wreck of her sister Titanic. Passengers were in a panic thinking the Olympic was going to sink just like Titanic did right in the same spot. The ship vibrated violently for about two minutes. The crew was informed it was a 7.2 magnitude earthquake near Newfoundland after via radio before they got the message rumors were spreading amongst the crew and passengers that they may have hit something but all inspections came up with no damage. Around 28 were killed in Newfoundland and Labrador because of it.
No worries, when designing for the Blocking plan, it must taken account for Earthquake. Extra side blocks are in place to ensure the ship won't tip over. But a block check is a must after earthquake.
Fortunately, NJ and the other fast battleships are flat bottomed, no "cradle" necessary like a destroyer or other round bottom ship would need. The very worst thing that an earthquake could do in this case would be to unseat the caisson and allow catastrophic flooding of the dock ... all at once. That WOULD probably seriously damage the ship by slamming her into the concrete far end and sides of the dock.
Disagree, spliting seams with the solid blocks instead of riding waves in water would be a real risk. Metal flexes over large areas but the blocks prevents it fom flexing as designed in water. Yes a breach of the dock could beat her up a bit too but she would float first and by then the flow could be countered with ropes unless it is in the form of a tidal wave that could lift her and set her on the sides of the dry dock.
Earthquakes on the East Coast are extremely rare, but they do happen. Obviously, they are not as frequent as earthquakes on the West Coast, but I digress. I'm in Dutchess County in New York, approximately 60 plus miles north of NYC. I was at my shop waiting for some parts for a car when a large flatbed truck came whizzing by. That's when everything started to shake. At first, I thought it was the draft of wind behind the truck that came by, because he was doing some high speeds for my road. I was looking all over the place. I saw the pictures on the walls in the office shaking. I saw the computer monitor shaking pretty bad as well, along with a faint noise of rumbling. Right then and there, I knew we had an earthquake happening.
We got ourselves two big shakes that day! First battleship to survive two earthquakes in dry dock on the same day? Give her a 20th battle star for that!
Take out a big insurance policy for bring her back to full operational condition in the event there's a bigger earthquake later on. Just so she can move on her own power back to Camden... or any other spot needing some geographic remodeling.
I was stationed aboard the USS Haleakala, AE-25, in Guam in '93. when we had a 7.8 magnitude earthquake. if you were on any of the ships in port you absolutely felt the earthquake. It was like being underway. mooring lines were smoking out and about to snap. one of the piers at Naval Station collapsed. it sounded like a jet flying by really low and the ground rolled like huge ripples on a pond. Crazy!
A magnitude 8 quake is more than 1000 times more powerful than a magnitude 4 quake. If a magnitude 8 quake hit the area, BB-62 would probably be off her blocks and tens of thousands of people would be injured or killed, and millions would be in need of emergency support.
Yeah, I could see how people not familiar with earthquakes might be concerned about a 4. However 3 is basically the threshold of when they are even noticeable anything is happening, and 5 tends to require something to be poorly setup to be doing damage to.
The other thing about this quake is that it was just a tremor without any real back and forth shaking afterwards. The one in 2011 actually did cause a noticeable amount of side-to side motion in the area nearby in things like pools, and that one they would have felt as it would displace the entire dry dock rather than just transmit vibrations. Probably would have not been an issue, but being under the ship during it would have been a sphincter-puckering moment.
That was one fortunate thing about this quake as opposed to the one in 2011 is that it did not seem to have a strong shear wave component after the initial tremor. The one in 2011 did, and being only a few miles away from the dry dock I can say that one had a lot of back-and-forth sway to it even here, enough to splash water out of the neighbors pool and require sea legs to walk.
My nephew and I were just preparing to leave my home in Connecticut on April 5th, 2024 when the earthquake struck at 10:23 A.M. . We were enroute to Philadelphia, Pa. for our 11:00 A.M. Drydock Tour of New Jersey and my first thoughts were of potential damage to the Drydock and the Battleship. She is literally a fish out of water at the moment and much more vulnerable than when she is in her natural element. As Ryan mentioned I recalled what the fate of the Japanese Battlecruiser Amagi had been and was most relieved that New Jersey and the dock were just fine. Glad you brought up this topic Ryan as I am sure the Amagi story has not been well circulated. We felt no tremors at my home in Eastern Connecticut.
At 5:05pm on 8/13/1868 the USS Wateree was anchored of what is now Arica, Chile when she was struck by an earthquake and about 2 hours later after the tsunamis died down found herself more than 430 yards inland. I have a shipwreck book that has this event in it. The Wateree only lost one person, but up to 25,000 lives were lost that day according to my book. The Wateree's boilers are still there per the book as well

In addition to destroying the Amagi, the currents from the great kanto earthquake partially lead to the navigational errors in the honda point disaster.
Here on the west coast, I've unknowingly been in earthquakes while driving, only to find out later on the news or, when talking with people who did feel it. Seismic waves caused by earthquakes produce oscillations, or vibrations. The drydock may be structurally sound and strong enough to tolerate the recent earthquake you experienced. But the drydock is affixed to the earth so when the earth under and around the drydock moves, the drydock must and will move along with it. No surprise the workers didn't feel it If they were up on lifts and operating blasting equipment because they were somewhat insulated by the lift and also getting shook around by their own activity.
Funny enough, when I first heard we were hit by an earthquake my first thought was if New Jersey was in some way damaged. Good to see she was also oblivious to it even happening.
I was on USS MarIano G, Vallejo SSBN-658 in drydock during new construction. Out Nav Center was running shift work during installation and acceptance testing. Several of us felt a movement of the ship on the blocks. That should not be possible, but we were in Mare Island Navy Yard in California and yes, we felt an earthquake. Don’t know the magnitude but it was minor. Those outside the ship said the yard workers scaled up the side of the drydock to get out from under the ship. We all had another “sea story” to share.
Parts of the east coast are in seismic zones and require buildings to be designed for earthquakes, not as severe as the west coast but the possibility is there. The ground shakes, the drydock is connected to the ground, it's going to shake. It won't wallow around and amplify any movements but it won't dissipate any movements either. It would take a very high earthquake but enough lateral force and the ship could knock the blocks over. One of the dangers with earthquakes is you can have vertical accelerations as well as horizontal which would give more chance of tipping over the blocks. I don't think that magnitude of earthquake could happen on the east coast, maybe not on the west coast, but Japan might be another matter.
Earthquakes shake up-down which is bad enough, but also side-to-side - which, close enough or strong enough, could roll even that big beautiful battleship right off those little tiny blocks😂 - glad all the hardware is ok!
For context, the Richter scale is logarithmic. So a magnitude 8 isn't twice as strong as a 4, it's 10,000 times as strong. That's why it was a non event for New Jersey, but destroyed Amagi.
I live in a converted wool millery building constructed in the 1840s in Seymour CT. I was sitting in an Ikea Rocking Chair and... as a retired Sailor? I got so sea sick! and I was sea sick for nearly an hour afterwards! and then the aftershock that came at 5pm? also surprised me. I'm still surprised this building didn't pancake.
The one area the Navy probably worries about earthquake-wise is the Puget Sound Area. While California, particularly the overdue southern portion, gets most of the attention regarding earthquakes, the Pacific Northwest has a fault system very similar to the one that caused a M 9+ earthquake and tsunami in 2011. The Cascadia Subduction Zone runs up from northern California to southern British Columbia and is very capable of generating a M 9 earthquake. It last went in early 1700. And of course Bremerton is where our CVNs in the Pacific Fleet get drydocked.
Well, the Destroyer Squadron that grounded and sank at Honda Point comes to mind. Japanese earthquake sets up a small tsunami that acts as a following sea throwing off the dead reckoning navigation of the group and thus they turn at the wrong time and all but a couple of the Clemson Class destroyers run hard aground at Honda Point. (Not 100% sure, but it might have even been the same quake that got AMAGI.)
I was dockmaster at Forgacs floating dock in Newcastle Australia and we had the brand new icebreaker Aurora Australis in the dock when we had the 1989 earthquake at 28-12-1989,10.27am it was about a 7, no damage to the ship
The composition of the frame in this video is awesome! You keep getting better and better. The production quality and videography is on a constant rise, keep at it. I'd love to see you guys get even more creative :)
The Mineral Earthquake (5.8) in 2011 made my house in Southern Maryland go up and down, as the shockwave went past us. It was probably just a few inches, but felt like a foot or more, as I was standing at the top of the stairs. We went outside immediately and the sidewalk was swaying from side to side. It’s an awfully strange feeling the first time that happens to you.
On April 8th, 1968, the RMS QUEEN MARY had just entered drydock two days prior at the Long Beach Naval Shipyard to begin her conversion to a hotel/museum. At 6:29pm PST, a magnitude 6.5 earthquake struck about 40 miles south of Palm Springs, CA. Referred to as the "Borrego Mountain Quake," it was the strongest and most destructive earthquake to hit Southern California since the Tehachapi Earthquake 16 years earlier. It was reported that the QUEEN MARY developed a rocking motion on her blocks that continued long after the quake had stopped. Luckily, everything remained upright.
LOL to continue with this, I have been aboard the QUEEN MARY during numerous earthquakes, including the 1994 Northridge Quake. They are very much felt on board, but for two reasons... 1- The QUEEN MARY's port side hull is up against large rollers that are fastened to two dolphins that extend out from the dockside. 2- The QUEEN MARY is moored with tightened steel braided cables at the bow, stern, and two breast lines amidships that are fastened to the hull by a special welded cleat just above the water line. These more rigid connections to "land" allow the shockwave energy to transfer to the ship. Usually, the QM will also develop a slow roll from port to starboard that can be noticeable if you are by the gangways or looking out from a porthole and watch the movement.
I was living in Marina Del Rey, during the Northridge earthquake. It messed up some water lines, in my apartment complex, and knocked an altimeter off the mantle. Later that day, we were working on a friend's 35 foot long sailboat, moored in the marina. Car alarms kept going off, (aftershocks) but we never felt a thing. I also worked at the complex, I did "continental breakfast" 5 days a week. Since it was an hour before I usually started, I went down and plugged in the coffee maker, and started breakfast. The rec room had a MASSIVE front screen TV, and everyone came down to see the news. (Also splashed out 6 or so inches of water, out of the pools.) steve
My brother in law lived in an apartment that was damaged in that quake. He had spent the night with my sister (they were not married yet) at her apartment and missed a bookcase falling onto his bed.
I was MAR DET USS MISSOURI at the end 1980s, the ship with USS NEW JERSEY were stationed at Long Beach California. I was on posts when a earthquake happened. On the ship i felt nothing but i watched vehicles on the pier shake, pretty cool.
Depends a lot on the wave. Some ships have had their backs broken by waves. If the crest of the wave lifts a ship unevenly between the fore, mid and aft there is a point that most ships will break. Also some have been rolled by a wave. It is better to ride out at sea but it still can happen.
I've slept through one earthquake aboard a small museum boat/ship (Hay Scow Alma). We were visiting Sausalito and were tied up for the night at a pier. Next day we heard everyone on the streets talking about some earthquake. As I recall it was the about the same size. A big quake might slam a ship when the pilings hit it. But my better story is about the last SF quake. Before we met, my spouse was working the ticket counter of the Pampanito, the WWII sub. Some people came out of the sub and asked what happened and were upset and demanded money back because they missed the quake!!!! She said bugger off you were in the safest place to be and closed the ship. She had to wait to be relieved by management which took a few hours due to the damage, fires, and traffic. She said the only obvious damage was a broken fire main ashore pouring water out from under the building.
I was a shop foreman for a large automotive dealership in northern Virginia back in 2011. We had some construction going on with the building the day the quake happened. I’ve never experienced an earthquake in my life prior to that day. I was standing in the middle of one of the shops talking to one of my team leaders when all of a sudden the building started shaking. The high bay ceiling lights were swinging back and forth and my team leader thought the roof was about to fall in due to the construction. So his first instinct was to jump under a car on a lift that was at its maximum height. After a second I realized what was happening and I shouted “it’s an earthquake get out from under that car!” And before he could even move I had grabbed him and dragged him out from under the car. Thankfully nobody at my dealer was hurt that day and there was no real property damage either. However the security camera footage reviewed after the event made for some really funny scenes.
Only notice one Midwest Earthquake. We were working on my demo derby car and one person was under it. It was on blocks and jack stands. The Earthquake shook so much the car fell. The guy under it barely got out in time. That car previously fell off jackstands pinning one and breaking several ribs. After the Earthquake we never raised it off the ground completely.
I live in Alaska and we have 6+ earthquakes 8 to 10 times a year. I have personally experienced an earthquake of 8.7 on the Richter Scale. The interesting thing is that every number increase onnthe Richter Scale is 10 time stronger than the previous number. For example, a 6.7 earthquake is 10 times stronger than a 6.6 earthquake. The Good Friday earthquake in 1964 in Alaska was originally classified as an 8.6 but recently found affected ares resulted in it being classified as 9.2. It caused a tsunami that wiped out the city of Seward and damaged many coastal areas. There was a railroad locomotive that was pushed from the dock in the Seward port 200 feet up the side of Mount Marathon on the other side of town and it remained there until it was cut apart and hauled away in 2014. There was only 2 buildings in Seward that survived the tsunami and every building in town was built after the earthquake. The locomotive was about 200 feet from the apartment that I lived in in 1978 and I used to climb all over it. It takes an enormous amount of force to roll a 200 ton steel object 1/2 of a mile and 200 feet up a mountain.
I work in a pipe factory in north nj. Building is fully concrete . Didn’t feel shit even though I was standing up while it happened . That text and everyone pausing to talk about it he described is exactly what happened at my shop too
1. ... Ryan, the US East Coast can get major earthquakes. Go to downtown Charleston, SC and look at the odd metal crosses in the walls of historic buildings that were added in the late 1800s as structural reinforcement after a big one hit here. 2. Easy to name a warship affected by earthquakes, since the Amagi wasn't the only one scrapped during construction after the Great Kanto Earthquake. The Sendai-class light cruiser Naka suffered the same fate - technically. Naka was completely scrapped in situ where she was being constructed due to quake damage, and that helped build a second version of her that became the Naka people remember.
Sometimes we forget the power of nature is greater than the power of these awesome ships! On December 18, 1944, a Pacific typhoon destroyed three destroyers and damaged several other ships. The USS Hull, USS Spence, and USS Monaghan capsized and sank with most of their crews. A cruiser, five aircraft carriers, and three destroyers also suffered severe damage
I commented after and the concern I had is with a quake the shifting forces even without knocking of blocks could break seams. The docks are tough and in a river bed the sediment around absorbs more of the waves. While the west coast has more and larger quakes, the east tends to be farther felt do to a thicker and harder plate under and harder sediments on the surface. This denser compact material transmitts waves more rather than absorb. I felt the DC quake in Charleston WV and historically the New Madrid quakes that moved the Mississippi bed 5 miles over also knocked people off their feet as far as the still young DC. As another noted blocks need rechecked and also the hull around the blocks should be scanned for any crack or stretch marks as even short of a leak could cause a weak spot or entryway for corrosion. I had found in a band saw I was getting ready for use again a weak spot that cracked after prior use that adjusted the wheel angle. I am glad I found it durring a replacement of tires and cooling blocks as at speed it could have sent a blade flying. A broken $1000 tool verses a hospital trip with missing fingers was IMHO a bargin. The cast part had a void with crystal like edges that caused the crack, it was a Porter Cable model and along with a Battery issue is Why I no longer buy power tools made by Black and Decker Stanley. (All the lowe's brands) BTW remember him placing his fingers in the wrong place in the keel vid, a stong wind might shift the load on the block but so could a quake. Wonder if Ryan had to do a safety bit after being caught in his vid?
Alabama wound up being damaged by Katrina, but that was more a case of physical structures that had been added on detaching. 'Bama herself wound up with an 8 degree list, a bit of damage to the bilge keels, and some damage to the hull when she broke loose from a set of concrete stairs.
Is the forward part of the ship already painted? It looks pretty good. Anyhow, I'm from California and I don't wake up for anything smaller than a 5.0. Neither do my dogs. And an 8.0 is about 1000x stronger than a 5.0
Working at Mare Island vallejo, California from 1974 to 1994 we had more than one earthquake the largest was loma prieta earthquake at 6.9 but I was not work. Also there was one the epicenter a tMare Island in 1891 some were between 5.8 to 6.4 and you still see repaired damage to this day.
Very cool! I had never thought about a ship being in dry dock during an earthquake. They are pretty exciting, aren't they? I've felt many of them, including four of them in the 7 magnitude range. I've never felt one of the east coast though and it's supposed to feel a bit different there. I believe it because the one I felt in South America felt different than the ones we have in California. I usually don't feel 4s so that is already different about that one.
I didn't realize the Japanese had started construction of Amagi, thought it was just another WoWs made up-ish boat, thx for the info Ryan! Glad NJ is just fine, those drydock foundations are probably a few feet thick I would imagine
Another battleship damaged by axe of gawd? Hmmm... Didn't Starfleet have a few battleships? Enquiring minds wanna know! Thanks Ryan, yer a good human bean. :)
Since I live only 10 minutes away from where it’s dry docked, that was one of my thoughts afterwards: Gee, it would be unpleasant to be under this ship if it slipped off. Be even worse if it fell on your legs. Good to see all is well 👍
Whoever setup the camera gets extra points. That’s a sick angle of the ship.
It shows off the rake and lines of her bow very nicely.
Star blazers vibes
Yep its even better for real.
@@robert506007 Agreed, absolutely stunning in person.
I totally agree. I was going to comment on the same thing.
Ryan, I honestly believe you are the only person _on earth_ who would feel an earthquake in a dry dock and think "Oh my God, I hope it's not the Amagi all over again!"
"When you put your battleship in dry dock" *vigorously takes notes* 😂😂 love you guys and love big jay
I absolutely love how your first thought was about the Amagi story. Ryan truely is a Naval history pro. 💖
New Jersey looks so good from the angle in this video. She’s beautiful.
This story was told to me by my room mate in Spain in about 1973... (I can't attest to the accuracy of it) It happened back in the 60's... he was on a submarine (USS Archerfish, SS-311, I think). They were in a drydock in Bremerton, WA He claimed he was down on the floor of the dry dock, underneath the sub when the earthquake struck (in Alaska, maybe?). He said the boat was bouncing on the keel blocks. He also said that some of the yardbirds later told him that he came out from under the boat at a dead run, ran to the closest wall, and scaled it like a spider.
The difference between a 46,000 ton battleship and a 3,000 ton submarine, sitting on the blocks.
The Easter 1964 quake was the largest ever recorded in North America since the invention of seismometers.
It has nothing to do with the total tonnage. It's the type of soil, strength of the earthquake, weight distribution of the ship and placment of the blocks. Ryan's comment about the strength of the drydock foundation reducing the shaking is without merit, while there are earthquake resistant structures it isn't about strength.
Depth, distance, soil types, and direction of the fault all have substantial effect on the feel of a quake. But generally speaking an energy of 4.5 is just a tiny shake that many people won't even notice if conditions aren't just so, about like a large truck driving by a few feet away. You really won't see damage or unsecured stuff falling over below about 5.5
6.0 is where you start to get notable structural damages to brittle structures and stuff falling off of shelves, 6.5 can be a big deal with some expensive repairs, 7 and up is a major emergency.
Speaking of soil density differences, are your damage estimates based on West coast quakes? The east coast contains much more bedrock which tends to carry the waves farther afield. i.e. the New Madrid quake, magnitude 7.2- 8.2, with a IV Mercalli scale or higher was felt over a 600K square km area, while the 1906 San Francisco quake, magnitude 7.8 magnitude, quake VII Mercalli scale was only felt in a 6.2 K square mile radius. Though, granted the San Francisco quake damage was greatly influenced by the type of fill that underlaid the port areas as well as the fact that SF was much more densely populated at the time with less infrastructure to damage.
The 1964 Alaska earthquake caused houseboats in Lake Union, Seattle to bounce around, a floating theatre in Green Lake to fall apart, and the Space Needle restaurant to stop rotating - so shaking a dry dock at Bremerton sounds reasonable.
I continue to be impressed with Ryan's presentations and knowledge. His delivery is smooth and very natural. Easier said than done. Kudos Ryan.
A lot of it is experience. Compare it to the first videos on the channel, he was a lot less confident back then.
!!!!!!!
Editing makes a difference too.
I just stumbled across this video and after about 20 seconds I was like....this guy is good!
Ryan knows his stuff, and can explain it very well.
Back in 1987 When the Whittier Narrows (SoCal) earthquake hit, 5.9 magnitude, the USS Leahy CG 16 was in drydock #3 at LBNSY. I was in the coordination center between drydocks 2 & 3. The building moved around really good and longer for the "average" earthquakes we have around here. A couple of my friends, a sheetmetal supervisor and his leader were on the 04 level of the Leahy and they said they could see the bow of the ship twisting. They just hugged each other until it was over. The inspectors found that the Leahy had moved 1.5" on her keel blocks.
That's pretty impressive that the weight of the ship on the blocks causes it to twist with the earth beneath it! Of course, the hull is meant to flex and twist to absorb the force of incoming waves, so it naturally should do so.
Magnitude matters. Every full point is a 10x increase in the power involved. Had this been an 7 or an 8 I'm sure the ship would have slipped some, or worse. That'd be a hell of a mess. About the only thing you could do is flood the dock and get her back up on the blocks to look for major damage. Short of a broken keel it would probably be fixable.
@@BlackEpyon I had a friend who was on pier 3 when it hit and he said the pier was rocking so badly he wasn't able to walk. 🙂 When the Oliver Hazard Perry class frigates were in drydock, they also had telephone poles mounted horizontally from the side of the drydock to the sides of the ship. They also placed a couple keel blocks on the fantail and forecastle, I guess for added weight.
@@chrismaverick9828 in that situation you'd better hope that the repairs being done will still allow the dock to be flooded, otherwise you're gonna have to get some strong cranes in
That earthquake felt A LOT bigger than 5.9 I can tell you! I've been in some way bigger ones too.
I'm so, so happy to see New Jersey in drydock. She's such a gorgeous ship. I'm glad she'll be around for at least the next 20 years. 🎉🎉🎉🎉🎉
She is even as beautiful out of the water as she is in the water!
Nah. There's no expiration date on a ship as long as people spend the time and money required.
I think she'll easily make it past 20 years. She's better built than USS Texas and look at the fact USS Texas is still here even after decades of mistakes and neglect. BB62 has the benefits of "best practices" for caring for it as learned from USS Texas's list of "what not to do". As long as the maintenance is kept up, she'll serve as a memorial and educational tool for decades and generations.

Awesome camera angle, what beautiful picture ship.!!
Doesn't matter how solid a foundation there is. Acceleration rate of the tectonic plate slipping is going to move anything attached to it. Combined with the direction of the acceleration is what ultimately decides whether a ship is going to get knocked off its blocks or not.
It is my understanding that most earthquake structural design is to allow the structure to ride out the earthquake using compliance not rigidity.
@@ricinro That's true. However, I don't think a dry dock would do too well having been designed for earth quakes. I could be wrong, but the math involved is too much to do on a whim. [ While writing this I looked but could not find 1920s concrete listed nor if they used rebar. I looked in all 3 of my engineers bible's. ] Now I'm kind of wanting to do the math...
Dang that ship is REALLY impressive in this video.
New Jersey is the Chuck Norris of battleships. New Jersey CAUSES earthquakes.
You win sir! 🍪 Take your cookie!
At night, the Boogie Man checks under the bed for USS New Jersey
an earthquake while on a ship that is in water is quite interesting. we had one, one morning at muster at long beach naval station. the ship and all of us on it were stationary, but you could see the pier, and vehicles on the pier moving back and forth about 10 feet. strangest looking thing to watch.
The biggest disappointment is: neither of the earthquakes that day was caused by the 16 inch guns firing.
Meh, those babies gotta be good for at least 5.0. ;)
It's one of those things you terribly want to happen, but have to find contentment in the fact it'll never happen. Boo hiss. Hiss boo. 😓
Sad 16 in/50 cal mk 7 noises
Cons : lose museum contract with navy
Pros : fire off 16 inch guns...
Hmmmmmmmmmm
@@beefgoat80there’s still a possibility of WW3 don’t worry
Kinda on subject but the ocean liner Olympic actually felt an earthquake in 1929 while sailing near the wreck of her sister Titanic. Passengers were in a panic thinking the Olympic was going to sink just like Titanic did right in the same spot. The ship vibrated violently for about two minutes. The crew was informed it was a 7.2 magnitude earthquake near Newfoundland after via radio before they got the message rumors were spreading amongst the crew and passengers that they may have hit something but all inspections came up with no damage. Around 28 were killed in Newfoundland and Labrador because of it.
You will never feel a earthquake in open ocean.
@@willardkeen9280 It was the water shaking them I guess. It’s just what I’ve heard.
@@willardkeen9280never let facts get in the way of a spooky story.
No worries, when designing for the Blocking plan, it must taken account for Earthquake. Extra side blocks are in place to ensure the ship won't tip over. But a block check is a must after earthquake.
Fortunately, NJ and the other fast battleships are flat bottomed, no "cradle" necessary like a destroyer or other round bottom ship would need.
The very worst thing that an earthquake could do in this case would be to unseat the caisson and allow catastrophic flooding of the dock ... all at once. That WOULD probably seriously damage the ship by slamming her into the concrete far end and sides of the dock.
Disagree, spliting seams with the solid blocks instead of riding waves in water would be a real risk. Metal flexes over large areas but the blocks prevents it fom flexing as designed in water. Yes a breach of the dock could beat her up a bit too but she would float first and by then the flow could be countered with ropes unless it is in the form of a tidal wave that could lift her and set her on the sides of the dry dock.
Earthquakes on the East Coast are extremely rare, but they do happen. Obviously, they are not as frequent as earthquakes on the West Coast, but I digress. I'm in Dutchess County in New York, approximately 60 plus miles north of NYC. I was at my shop waiting for some parts for a car when a large flatbed truck came whizzing by. That's when everything started to shake. At first, I thought it was the draft of wind behind the truck that came by, because he was doing some high speeds for my road. I was looking all over the place. I saw the pictures on the walls in the office shaking. I saw the computer monitor shaking pretty bad as well, along with a faint noise of rumbling. Right then and there, I knew we had an earthquake happening.
We got ourselves two big shakes that day! First battleship to survive two earthquakes in dry dock on the same day?
Give her a 20th battle star for that!
Take out a big insurance policy for bring her back to full operational condition in the event there's a bigger earthquake later on. Just so she can move on her own power back to Camden... or any other spot needing some geographic remodeling.

I was stationed aboard the USS Haleakala, AE-25, in Guam in '93. when we had a 7.8 magnitude earthquake. if you were on any of the ships in port you absolutely felt the earthquake. It was like being underway. mooring lines were smoking out and about to snap. one of the piers at Naval Station collapsed. it sounded like a jet flying by really low and the ground rolled like huge ripples on a pond. Crazy!
Two minutes after the earthquake, I messaged Ryan my concerns for him and the men working on the ship thankfully, they said they didn’t even feel it
I served a long side the New Jersey while in Vietnam. Amazing ship!
A magnitude 8 quake is more than 1000 times more powerful than a magnitude 4 quake. If a magnitude 8 quake hit the area, BB-62 would probably be off her blocks and tens of thousands of people would be injured or killed, and millions would be in need of emergency support.
Yeah, I could see how people not familiar with earthquakes might be concerned about a 4. However 3 is basically the threshold of when they are even noticeable anything is happening, and 5 tends to require something to be poorly setup to be doing damage to.
Exactly. Knocking some knick naks off the shelves isn’t anywhere near knocking a battleship off her keel blocks.
2x ...
@@BronxBastard730no, each point higher on the scale represents an order of magnitude increase of energy released.
The other thing about this quake is that it was just a tremor without any real back and forth shaking afterwards. The one in 2011 actually did cause a noticeable amount of side-to side motion in the area nearby in things like pools, and that one they would have felt as it would displace the entire dry dock rather than just transmit vibrations. Probably would have not been an issue, but being under the ship during it would have been a sphincter-puckering moment.
Ryan you are one amazing curator, keeper of the keys, guardian, steward.. educator....... Etc! You deserve a great big raisw my friend.
That was one fortunate thing about this quake as opposed to the one in 2011 is that it did not seem to have a strong shear wave component after the initial tremor. The one in 2011 did, and being only a few miles away from the dry dock I can say that one had a lot of back-and-forth sway to it even here, enough to splash water out of the neighbors pool and require sea legs to walk.
My nephew and I were just preparing to leave my home in Connecticut on April 5th, 2024 when the earthquake struck at 10:23 A.M. . We were enroute to Philadelphia, Pa. for our 11:00 A.M. Drydock Tour of New Jersey and my first thoughts were of potential damage to the Drydock and the Battleship. She is literally a fish out of water at the moment and much more vulnerable than when she is in her natural element. As Ryan mentioned I recalled what the fate of the Japanese Battlecruiser Amagi had been and was most relieved that New Jersey and the dock were just fine. Glad you brought up this topic Ryan as I am sure the Amagi story has not been well circulated. We felt no tremors at my home in Eastern Connecticut.
At 5:05pm on 8/13/1868 the USS Wateree was anchored of what is now Arica, Chile when she was struck by an earthquake and about 2 hours later after the tsunamis died down found herself more than 430 yards inland. I have a shipwreck book that has this event in it. The Wateree only lost one person, but up to 25,000 lives were lost that day according to my book. The Wateree's boilers are still there per the book as well
If you look at Wikipedia for her, there is a picture of what's left of the boilers.

In addition to destroying the Amagi, the currents from the great kanto earthquake partially lead to the navigational errors in the honda point disaster.
Fascinating!
A propeller from one of the lost destroyers is on display at the VA Center in Lompoc, CA not far from Honda Point. Thanks for that information!
Here on the west coast, I've unknowingly been in earthquakes while driving, only to find out later on the news or, when talking with people who did feel it. Seismic waves caused by earthquakes produce oscillations, or vibrations. The drydock may be structurally sound and strong enough to tolerate the recent earthquake you experienced. But the drydock is affixed to the earth so when the earth under and around the drydock moves, the drydock must and will move along with it. No surprise the workers didn't feel it If they were up on lifts and operating blasting equipment because they were somewhat insulated by the lift and also getting shook around by their own activity.
A tad early for her post dry dock shakedown cruise..
Good one!
So that's how the Kaga came about as a carrier!!! Super neat!!!
Funny enough, when I first heard we were hit by an earthquake my first thought was if New Jersey was in some way damaged. Good to see she was also oblivious to it even happening.
I was on USS MarIano G, Vallejo SSBN-658 in drydock during new construction. Out Nav Center was running shift work during installation and acceptance testing. Several of us felt a movement of the ship on the blocks. That should not be possible, but we were in Mare Island Navy Yard in California and yes, we felt an earthquake. Don’t know the magnitude but it was minor. Those outside the ship said the yard workers scaled up the side of the drydock to get out from under the ship. We all had another “sea story” to share.
Parts of the east coast are in seismic zones and require buildings to be designed for earthquakes, not as severe as the west coast but the possibility is there.
The ground shakes, the drydock is connected to the ground, it's going to shake. It won't wallow around and amplify any movements but it won't dissipate any movements either. It would take a very high earthquake but enough lateral force and the ship could knock the blocks over. One of the dangers with earthquakes is you can have vertical accelerations as well as horizontal which would give more chance of tipping over the blocks. I don't think that magnitude of earthquake could happen on the east coast, maybe not on the west coast, but Japan might be another matter.
We know Ryan was out there afterwards hugging some part of the ship saying "I'm so glad your ok!"
I was on Guam when several earthquakes struck. Kinda neat for a 20 year old sailor........Jay
But did Guam threaten to tip over?😎
We felt it here in Schyulkill County PA
what a beautiful ship.
My son's Eagle ceremony was on the Surrender Deck while it was in the Long Beach Naval Station. Great day!
Earthquakes shake up-down which is bad enough, but also side-to-side - which, close enough or strong enough, could roll even that big beautiful battleship right off those little tiny blocks😂 - glad all the hardware is ok!
For context, the Richter scale is logarithmic. So a magnitude 8 isn't twice as strong as a 4, it's 10,000 times as strong. That's why it was a non event for New Jersey, but destroyed Amagi.
The New Jersey survives another battle!
Such a Majestic back scape! Rock on Ryan!
Very glad she didn't even notice, for sure!
I live in a converted wool millery building constructed in the 1840s in Seymour CT. I was sitting in an Ikea Rocking Chair and... as a retired Sailor? I got so sea sick! and I was sea sick for nearly an hour afterwards! and then the aftershock that came at 5pm? also surprised me. I'm still surprised this building didn't pancake.
Hi Ryan. I was in central Vermont at the time and we felt it about 40 seconds after you guys in NJ felt it. Crazy!
Great conversation
The one area the Navy probably worries about earthquake-wise is the Puget Sound Area. While California, particularly the overdue southern portion, gets most of the attention regarding earthquakes, the Pacific Northwest has a fault system very similar to the one that caused a M 9+ earthquake and tsunami in 2011. The Cascadia Subduction Zone runs up from northern California to southern British Columbia and is very capable of generating a M 9 earthquake. It last went in early 1700. And of course Bremerton is where our CVNs in the Pacific Fleet get drydocked.
Great video! Glad to see you guys know your history.
The paint-job is so crisp. She looks absolutely metal!
Well, the Destroyer Squadron that grounded and sank at Honda Point comes to mind. Japanese earthquake sets up a small tsunami that acts as a following sea throwing off the dead reckoning navigation of the group and thus they turn at the wrong time and all but a couple of the Clemson Class destroyers run hard aground at Honda Point. (Not 100% sure, but it might have even been the same quake that got AMAGI.)
I was dockmaster at Forgacs floating dock in Newcastle Australia and we had the brand new icebreaker Aurora Australis in the dock when we had the 1989 earthquake at 28-12-1989,10.27am it was about a 7, no damage to the ship
No stationary camera view of the ship in dry dock during the earthquake? That would be interesting to see what kind of movement there was.
Thanks as always!
Thanks for the history of ‘Amagi’ and it is such a treat to see ‘New Jersey’ in what would have been CC-1 ‘Lexington’’s dry dock!
The composition of the frame in this video is awesome!
You keep getting better and better. The production quality and videography is on a constant rise, keep at it. I'd love to see you guys get even more creative :)
Very interesting. Thanks for sharing this insight.
Very fact filled video.
The Mineral Earthquake (5.8) in 2011 made my house in Southern Maryland go up and down, as the shockwave went past us. It was probably just a few inches, but felt like a foot or more, as I was standing at the top of the stairs. We went outside immediately and the sidewalk was swaying from side to side. It’s an awfully strange feeling the first time that happens to you.
Great view from up there. You can see how much is below water in order to float all that thick steel.
That is a GREAT view of the battleship.
I daresay you'd rather not think of it, but what would the follow up be if she had slipped off her blocks?
On April 8th, 1968, the RMS QUEEN MARY had just entered drydock two days prior at the Long Beach Naval Shipyard to begin her conversion to a hotel/museum. At 6:29pm PST, a magnitude 6.5 earthquake struck about 40 miles south of Palm Springs, CA. Referred to as the "Borrego Mountain Quake," it was the strongest and most destructive earthquake to hit Southern California since the Tehachapi Earthquake 16 years earlier. It was reported that the QUEEN MARY developed a rocking motion on her blocks that continued long after the quake had stopped. Luckily, everything remained upright.
LOL to continue with this, I have been aboard the QUEEN MARY during numerous earthquakes, including the 1994 Northridge Quake. They are very much felt on board, but for two reasons... 1- The QUEEN MARY's port side hull is up against large rollers that are fastened to two dolphins that extend out from the dockside. 2- The QUEEN MARY is moored with tightened steel braided cables at the bow, stern, and two breast lines amidships that are fastened to the hull by a special welded cleat just above the water line. These more rigid connections to "land" allow the shockwave energy to transfer to the ship. Usually, the QM will also develop a slow roll from port to starboard that can be noticeable if you are by the gangways or looking out from a porthole and watch the movement.
I was living in Marina Del Rey, during the Northridge
earthquake. It messed up some water lines, in my
apartment complex, and knocked an altimeter off
the mantle.
Later that day, we were working on a friend's 35
foot long sailboat, moored in the marina. Car
alarms kept going off, (aftershocks) but we never
felt a thing.
I also worked at the complex, I did "continental
breakfast" 5 days a week. Since it was an hour
before I usually started, I went down and plugged
in the coffee maker, and started breakfast. The
rec room had a MASSIVE front screen TV, and
everyone came down to see the news. (Also
splashed out 6 or so inches of water, out of the
pools.)

My brother in law lived in an apartment that was damaged in that quake. He had spent the night with my sister (they were not married yet) at her apartment and missed a bookcase falling onto his bed.
Awesome!
Glad that the Jersey didn't fall off the blocks. And also glad the poopdeck made it unscathed.
Would LOVE for you to do a video on the dry dock itself including how it can take all that weight. Does it have pilings down to bedrock?
Sea trials on dry land. The ship and the workers were the 1st thing I thought about when it was on the news.🙏
Oh my. The cost of living in California has gotten so expensive, that even Earthquakes are leaving.
I was MAR DET USS MISSOURI at the end 1980s, the ship with USS NEW JERSEY were stationed at Long Beach California. I was on posts when a earthquake happened. On the ship i felt nothing but i watched vehicles on the pier shake, pretty cool.
Tsunamis don't impact ships unless they are close to shore. Indeed, the passage of a tsunami is even hard to detect midocean.
Depends a lot on the wave. Some ships have had their backs broken by waves. If the crest of the wave lifts a ship unevenly between the fore, mid and aft there is a point that most ships will break. Also some have been rolled by a wave. It is better to ride out at sea but it still can happen.
Cool story I never heard of till now.
“SHIP OUT OF WATER!”
It was then that little Johnny knew he was playing the wrong game in the pool.
I was on the Arkansas CGN-41 when it was in drydock at PSNS back in the latter half of the 90's, and it was... interesting.
I've slept through one earthquake aboard a small museum boat/ship (Hay Scow Alma). We were visiting Sausalito and were tied up for the night at a pier. Next day we heard everyone on the streets talking about some earthquake. As I recall it was the about the same size. A big quake might slam a ship when the pilings hit it. But my better story is about the last SF quake. Before we met, my spouse was working the ticket counter of the Pampanito, the WWII sub. Some people came out of the sub and asked what happened and were upset and demanded money back because they missed the quake!!!! She said bugger off you were in the safest place to be and closed the ship. She had to wait to be relieved by management which took a few hours due to the damage, fires, and traffic. She said the only obvious damage was a broken fire main ashore pouring water out from under the building.
Damn, that is a fine look'n vantage point to view the NJ
I was a shop foreman for a large automotive dealership in northern Virginia back in 2011. We had some construction going on with the building the day the quake happened. I’ve never experienced an earthquake in my life prior to that day. I was standing in the middle of one of the shops talking to one of my team leaders when all of a sudden the building started shaking. The high bay ceiling lights were swinging back and forth and my team leader thought the roof was about to fall in due to the construction. So his first instinct was to jump under a car on a lift that was at its maximum height. After a second I realized what was happening and I shouted “it’s an earthquake get out from under that car!” And before he could even move I had grabbed him and dragged him out from under the car. Thankfully nobody at my dealer was hurt that day and there was no real property damage either. However the security camera footage reviewed after the event made for some really funny scenes.
i remember the 2011 one. Was in bensalem PA when it happened. Jolted the store i was working in.
Only notice one Midwest Earthquake. We were working on my demo derby car and one person was under it. It was on blocks and jack stands. The Earthquake shook so much the car fell. The guy under it barely got out in time. That car previously fell off jackstands pinning one and breaking several ribs. After the Earthquake we never raised it off the ground completely.
I live in Alaska and we have 6+ earthquakes 8 to 10 times a year. I have personally experienced an earthquake of 8.7 on the Richter Scale. The interesting thing is that every number increase onnthe Richter Scale is 10 time stronger than the previous number. For example, a 6.7 earthquake is 10 times stronger than a 6.6 earthquake. The Good Friday earthquake in 1964 in Alaska was originally classified as an 8.6 but recently found affected ares resulted in it being classified as 9.2. It caused a tsunami that wiped out the city of Seward and damaged many coastal areas. There was a railroad locomotive that was pushed from the dock in the Seward port 200 feet up the side of Mount Marathon on the other side of town and it remained there until it was cut apart and hauled away in 2014. There was only 2 buildings in Seward that survived the tsunami and every building in town was built after the earthquake. The locomotive was about 200 feet from the apartment that I lived in in 1978 and I used to climb all over it. It takes an enormous amount of force to roll a 200 ton steel object 1/2 of a mile and 200 feet up a mountain.
I work in a pipe factory in north nj. Building is fully concrete . Didn’t feel shit even though I was standing up while it happened . That text and everyone pausing to talk about it he described is exactly what happened at my shop too
1. ... Ryan, the US East Coast can get major earthquakes. Go to downtown Charleston, SC and look at the odd metal crosses in the walls of historic buildings that were added in the late 1800s as structural reinforcement after a big one hit here.
2. Easy to name a warship affected by earthquakes, since the Amagi wasn't the only one scrapped during construction after the Great Kanto Earthquake. The Sendai-class light cruiser Naka suffered the same fate - technically. Naka was completely scrapped in situ where she was being constructed due to quake damage, and that helped build a second version of her that became the Naka people remember.
She is still making history. 🎉
Felt it in Oneonta, NY.
Sometimes we forget the power of nature is greater than the power of these awesome ships! On December 18, 1944, a Pacific typhoon destroyed three destroyers and damaged several other ships. The USS Hull, USS Spence, and USS Monaghan capsized and sank with most of their crews. A cruiser, five aircraft carriers, and three destroyers also suffered severe damage
There was one in the mid 80’s when I was growing up in NJ, was upper 3’s low 4’s.
I commented after and the concern I had is with a quake the shifting forces even without knocking of blocks could break seams. The docks are tough and in a river bed the sediment around absorbs more of the waves. While the west coast has more and larger quakes, the east tends to be farther felt do to a thicker and harder plate under and harder sediments on the surface. This denser compact material transmitts waves more rather than absorb. I felt the DC quake in Charleston WV and historically the New Madrid quakes that moved the Mississippi bed 5 miles over also knocked people off their feet as far as the still young DC. As another noted blocks need rechecked and also the hull around the blocks should be scanned for any crack or stretch marks as even short of a leak could cause a weak spot or entryway for corrosion. I had found in a band saw I was getting ready for use again a weak spot that cracked after prior use that adjusted the wheel angle. I am glad I found it durring a replacement of tires and cooling blocks as at speed it could have sent a blade flying. A broken $1000 tool verses a hospital trip with missing fingers was IMHO a bargin. The cast part had a void with crystal like edges that caused the crack, it was a Porter Cable model and along with a Battery issue is Why I no longer buy power tools made by Black and Decker Stanley. (All the lowe's brands) BTW remember him placing his fingers in the wrong place in the keel vid, a stong wind might shift the load on the block but so could a quake. Wonder if Ryan had to do a safety bit after being caught in his vid?
We felt that 2011 earthquake all the way in Salisbury on the Eastern shore. It went slot further than B-more lol.
I sure do love that ship, its my second fav behind the Texas (I am from texas)
Alabama wound up being damaged by Katrina, but that was more a case of physical structures that had been added on detaching. 'Bama herself wound up with an 8 degree list, a bit of damage to the bilge keels, and some damage to the hull when she broke loose from a set of concrete stairs.
Is the forward part of the ship already painted? It looks pretty good.
Anyhow, I'm from California and I don't wake up for anything smaller than a 5.0. Neither do my dogs. And an 8.0 is about 1000x stronger than a 5.0
I believe they started with the stern first
The one and 2011 was felt in PA as well near Trenton
Working at Mare Island vallejo, California from 1974 to 1994 we had more than one earthquake the largest was loma prieta earthquake at 6.9 but I was not work. Also there was one the epicenter a tMare Island in 1891 some were between 5.8 to 6.4 and you still see repaired damage to this day.
Typhoon Cobra caused a lot of damage to the battle ships and I recall a destroyer or two sank. 1944?
Great video! 👍
There was a minor one when I was working on the Ohio at PSNS, supposedly it just kind of settled it on the blocks a little more level.
Very cool! I had never thought about a ship being in dry dock during an earthquake. They are pretty exciting, aren't they? I've felt many of them, including four of them in the 7 magnitude range. I've never felt one of the east coast though and it's supposed to feel a bit different there. I believe it because the one I felt in South America felt different than the ones we have in California. I usually don't feel 4s so that is already different about that one.
I didn't realize the Japanese had started construction of Amagi, thought it was just another WoWs made up-ish boat, thx for the info Ryan! Glad NJ is just fine, those drydock foundations are probably a few feet thick I would imagine
Another battleship damaged by axe of gawd? Hmmm... Didn't Starfleet have a few battleships? Enquiring minds wanna know!
Thanks Ryan, yer a good human bean. :)
Since I live only 10 minutes away from where it’s dry docked, that was one of my thoughts afterwards: Gee, it would be unpleasant to be under this ship if it slipped off. Be even worse if it fell on your legs. Good to see all is well 👍
