Ah man, the thing about detection range reminded me of something. Many, many years ago I was volunteering to help organize some OSRD documents at the Library of Congress and stumbled across a report in Division 14, radar, about the Navy wanting a radar that could detect a ship from 100 miles away. It said the antenna had to be 5,000 feet up in the air. It then said that they could put it on a 5,000 foot mast, but this was considered impractical, so instead it should be in a plane flying at 5,000, and I kid you not there was a hand drawn picture of a ship with a 5,000 foot mast and an Avenger flying next to it. It was really funny and I wish I had written down its OSRD number.

Sorry, not buying your story. The horizon at 5000 ft is only 50 miles, not 100. And nobody outside of the internet would suggest using a ship's mast a mile tall vs. just putting up a tethered balloon that would actually work.
They hit picket ships on the edges of the fleet alot due to the absolutely wicked AA fire with proximity fuses. It was all but impossible for them to get through to the main ships of the fleet, although it occasionally happened.
And it was h*ll for the picked ship on the edges. It was very rough duty with quite heavy casulties. In some sense, it can be compared to being the first wave, your chances to survive were reduced significantly if you had this duty.
Divine Wind also hastened the conversion of Navy fighter armament from .50 machine guns to 20mm cannon. They realized that simply punching lots of holes wasn't enough; they had to blast the enemy planes to pieces in the air. Same with ship-based AA--the Navy started developing 3" automatic cannon to replace the 40mm and 20mm guns.

@@TheStephaneAdam Cost estimates that ignore the resources required to create a capable Kamikaze pilot are useless; we can just as easily say, "Kamikazes were the most expensive weapon used by Japan, because they spent resource-intensive pilots to damage or destroy ships that had lost almost all tactical relevance, and would need to be scrapped after the war anyway." And these were not small costs: Japan spent resources it could very much not spare making and supplying airfields close enough to front lines to create veteran pilots, and these in turn needed ships for both supply and defense, along with ground support, magnifying costs immensely. When these pilots were thrown away for the sake of failing to accomplish any and all strategic objectives, every ounce of labor and time needed to create and protect them was wasted too. By the time Japan started using untrained pilots to lower costs, it was too late, because the nukes ended all chances of seeing if non-veteran pilots could be used cost-effectively.
Yeah, the destroyer pickets took some serious damage. My late grandfathers ship (USS Stanley DD-478) was hit by on Ohka rocket kamikaze off Okinawa on April 13, 1945 (IIRC) while on radar picket duty. His ship got lucky in that the Ohka didn't explode but punched clean through the ship. A second Ohka was a near miss.
My Uncle was lost May 28, 45 off the coast of Okinawa. USS Drexler DD741. It was hit by two kamikaze planes. The first plane hit amidship starboard but reports from survivors said the ship could have survived that hit. A second plane had missed his target ship, his landing gear left a skidmark on A turret, then he flew over the Drexler and circled back hitting the aft 5” magazine. 3 minutes after the first hit and only 49 seconds after the second hit the ship was gone. I think 169 lost. Their job had been to protect Marines on landing craft. Bless those Marines for turning back under fire to rescue near 200 survivors. The last survivor passed in 2023.

Aren't WW2 (since no missiles) troop ships (supposed to be) in the center, surrounded by warships? I haven't yet watched the video, but it seems that you'd have a harder time getting to them than even aircraft carriers. And once you sink them, hitting transports is easier. Hypothetically.
@@RonJohn63 they would be until the day of the invasion of Japan. The troop transports would be closest to shore and more vulnerable than the warships.

Great warriors win battles, great logistics win wars, historical data has shown that time after time wars were changed by logistics or lost by failure to adapt to the situation...
@stephencrockard7093 this was really core to the US fight and Victory at Guadalcanal. The US Navy and Marine Pilots largely denied the Japanese ability to reinforce and resupply their force on Guadalcanal. The Japanese forces on Guadalcanal ran out of food, medicine and ammo as the campaign went on.
It's a funny thing but I understand that their Loyalty To The Emperor and their Devotion To Country overcame all of that, enabling the sinking of 100 American carriers! At least that's what was in the reports...
Remimded me of the old movie, "Tora-Tora-Tora": the officers were drilling the pilots on their ability.to recognize ships expected to be at Pearl.Harbor. they were quite fast to recoginize the picture but.when an aircraft carrier picture was shown, the pilots were quiet then one memtion a US N aircraft.carrier (I forgot the name). The officer doing the drills jokingly said ( in Japanese) "Idiot, this is your own ship".
You wonder if maybe they just didn't have enough experience to recognize what a big ship actually looked like. A destroyer would have multiple funnels and multiple turrets all spitting out fire and seem pretty large and imposing, if you'd never actually seen a big ship before you might not realize how much bigger a cruiser or battleship could be.
The impact was huge for freedom of movement, too. Even the AAA costs likely exceeded the attacking aircraft significantly and the human life cost was in Japan's favour. If they'd gotten their tunnel launch sites in the mountains running that 30 mile warning requirement would push the allied ships to at least 50 miles or so from shore. It's a real pain to deal with Japan's topography too. And the inherent risk running air screens, each carrier landing being quite hazardous, never mind the weather. I wouldn't say countermeasures were 'effective' but they did everything possible to minimise it- it was still a gigantic morale blow for the sailors. Compared to the u-boat threat this was much more significant and difficult to deal with. Once you lose more airmen to conventional attacks it only makes sense.
Absent the Atomic Bombs, the Kamikazes may have been more effective in November 1945, when when the invasion of the home islands would have kicked off with Olympic on the island of Kyushu. After the war we discovered: 1. They had correctly deduced where and about when we would land. 2. They had been stockpiling aircraft of all type, from frontline fighters and bombers to cargo and training planes. Including obsolete ones. Basically, anything that could take-off. While many would have been easy prey, Japan had accumulated approximately 10,000 flyable planes for the purpose. 3. Last, but worst, not least, they had a new strategy. Recognizing that attacking warships bristling with guns of all types had failed completely against the Battleships, Fleet Carriers and Cruisers that made such attractive targets they were NOT going to even try. Instead the new plan was to go after the troop ships. Even easier to sink than destroyers they contained the very men who were to land on the home island. My father was going to be on one of those troopships.
@@M1903a4 my dad, after serving in Germany, had actual battle maps for invading Japanese occupied China. Such maps had a little number at the top for estimated casualties, often a single digit number like 4.0. This number was 40. A typo? He asked? No
Fantastic video! The only major point that needs to be considered is that while sinking a ship is clearly the desired outcome, and a hit is certainly sub-optimal, ultimately a mission-kill that neutralises the vessel is a key factor. If that vessel is out of the fight, it doesn't really matter if it is at the bottom of the ocean or being towed back to Uluthi or Pearl or San Diego. And particularly with the destroyer example, a DD hit by a kamikaze, even if not sunk, is almost always going to be completely hors d combat. Similarly while a hit is a useful metric for strike-rate effectiveness, but we only have to think of the darkly funny picture of the poor guy who tried to hit HMS Sussex and left nothing more that a looney toons imprint on the armour plate.
Kamikaze were effective when it came to create panic in aircraft carriers and other ships crews. Also using Nakajimas Ki-84 Hayates as a kamikaze was sheer stupidity and a waste of a good airplane!
Great video as always. Very informative but it raised my curiosity. The Essex class had nominally 12*5 inch guns as heavy AA defense and those were the first line of ship self defense. How did the British carriers fare in that department? They had 16*4.5 inch guns with much of the same range and performance. Also, did the asymmetrical placement of the Essex 5 inch guns a factor in how the ships maneuvered to get the most guns to bear? I know it's a rabbit hole, but on the tactical level defending the ships, those questions must have had an influence.
Another excellent video. One thing I've been wondering about, so often I've heard people say that kamikaze were a tactic of pure desperation. On the other hand I heard from somebody who had actually studied the use of kamikazes that there was an actual pragmatic approach to the use of kamikaze - that losses of aircraft and pilots in conventional use were so high, that it mathematically, if one out kamikaze actually hit a ship, more damage for ten aircraft and pilots was inflicted than if the ten were lost without inflicting any damage. Do you know of any such statistics?
This analysis is correct. When they switched to these tactics, their success in regular c*mbat was extremly low, because of being outgunned and outclassed at this point. So yes, the Kamikaze did indeed more damage than would have been done if they would have fought conventionally. Ian Toll writes about it in his Pacific Crucible trilogy.
@@wedgeantilles8575 But I mean specifically, effectiveness per lives lost. The assumption is that in conventional warfare _some_ pilots will return, whereas with kamikaze, almost no pilots will return - yes, some did turn back because of mechanical failure, like engine problems, and land, but I imagine those were few and far between.
@@DerOrso During this time of war, not that many pilots returned anyway. They were running out of skilled pilots fast and green pilots got sl**ghtered out there. Kamikaze had the additional benefit, that you could achieve more with limited skills. Hitting a ship with torpedos or bombs was very difficult.
@@wedgeantilles8575 Very true. Trying to deliver a munition is such a way that you 1) have a good chance of hitting, and 2) have some chance of getting away, is harder than just "aim for the boat". The more one looks at the situation, the less crazy is sound. And when you consider, all Japan really wanted, overall, was to be included in the colonizing nations, like Britain, France, Holland, Portugal, Germany, and the US, and not be colonized like China. There were only the two choices, because the known colonizers always came and colonized every nation with exploitable resources they could; no exceptions. When you consider that only 90 years prior, Japan looked more like 17th century Europe, or even older, with only very limited technology, and 90 years later they actually lead the world in naval aviation, the most technologically advanced form of warfare in existence at the time. And all that because they were certain, they didn't want to be colonized.
Not only are the DD's on the outer pickets, hence the higher numbers of Kamikaze attacks on them, but they are also much more numerous than BB's and CV's. A battle group would consist of roughly 15 flat-tops (CV, CVL), 8 BB's, 15 cruisers, and 75 dd's.
If games like War Thunder are in any manner comparable to real air warfare, I'd imagine kamikaze attacks are the closest, as the players aren't usually interested in surviving the attack as long as they get a hit. Having played such attacks against enemy fleet, I also notice the tendency to attack the first ship that spots the plane, simply because from the point you're spotted onwards, you're basically on borrowed time - even if you managed to survive the first ship's AA, you very likely won't survive the entire fleet others who are very aware of you by this point and will shoot you into pieces if you get anywhere near.
And yes, I know real air attacks weren't most of the time done with individual planes, but on the other hand, hitting the nearest ship may increase the chances of your squadmates getting past it. Or that's what one would think intuitively, at least.
I believe the armored decks came about more as an acknowledgement that carriers of the time may have little warning to respond to an attack, and if they’re operating in the Med then they’d have to contend with land bases operating more and heavier aircraft on a continent instead of carriers and island airfields. The downside was their lower hangar height which limited what aircraft they could operate and thus their value as a carrier.
@@classifiedad1 Indeed. I believe there was an American naval officer serving as liaison to the Royal Navy. Regarding kamikazes he said something to the effect of, if an American carrier takes a kamikaze to the flight deck, it's six months in Pearl Harbor. If an RN carrier takes a kamikaze to the flight deck it's "sweepers, man your brooms." Different ships, built under different doctrines, fighting a war they probably weren't designed for. You fight with what you've got, not what you want.
Another wartime lesson about the kamikaze and the 40 mm Bofors: post war the USN began replacing the 40 mm with the advanced 3”/50 MK 22 on mounts MK 27, 33 & 34. The conclusion was the kamikaze had to be smashed into bits a task a single or so 40 mm and smaller shell could not do. Like a guided mission today, a kamikaze wasn’t aff3cted by the psychological effects of tracers flying by. The 3”/50 shell was the smallest that at the time could carry a VT fuse. (Today 40 mm shells can be fitted with multi function fuses and the 40 mm today can be fitted in unmanned, fully automatic mounts such as the OTO-Breda 40/70 Fast 40 twins.) As for the famous 20mm Oerlikon the saying was, “when the 20s open fire it’s time to brace for impact.”

How do these numbers change when you include the UK and commonwealth BPF ships in the data? As the UK aircraft carriers had armoured flight decks they were often used closer inshore.
3:25 Yeah, I was never the most well read about the Kamikaze attacks, but just from seeing general history, it did seem Destroyers bore the brunt of the attacks despite Capital Ships being the preferred targets. Carriers especially were what Japan were most worried about yet they were among the least to be attacked. I also know the USN even made it a point to push Destroyers out far away on Radar picket duty with Fighter Caps. Kamikazes were drawn towards them. This was acceptable to the US Navy because the Carriers were so valuable while the service had more Destroyers. Not to mention Carriers and Battleships tend to be in the center of USN air defense formations. So Kamikaze would have to deal with Fighter Caps, layers of Anti-Aircraft Fire, and then MAYBE get a shot to make a run against a Capital Ship. Also understandable that Kamikazes had good hit rates against Escort Carriers. They were small, cheaply made for fast construction and very slow. They would not have been bristling with AA guns compared to the larger, more heavily defended Fleet Carriers like Enterprise, Saratoga, and Essex-class. Even the Independence-class Light Carriers didn't fare badly like the CVEs because they were faster and had better AA guns, i.e. more 40mm Bofors than the Escort Carriers that tended to have lighter, weaker, shorter ranged 20mm Oerlikons. Worsening Kamikaze success rates as time went on is understandable. No matter the conflict your enemy is actually rather smart and will figure things out and get better.
Proximity fuse "qoute: How effective is the proximity fuse? The proximity fuse proved three to four times more effective than conventional time fuses, and night kill-ratios increased by 370%. In 1943, naval guns fired 36,370 antiaircraft rounds. Although only 25% used proximity fuses, these accounted for 51% of the kills.
The K-pilots were instructed to not target battleships or cruisers because their armor made them immune to serious damage by the slow flying planes. Many K-pilots flew multiple missions when they failed to find USN ships. That is one reason a substantial number survived the war. Dairies and post war interviews show many of the men knew their efforts were futile and flew the missions only because of intense pressure.
16:18 Music is drowning out your words. Could not understand what percentage hit targets; had to do math to subtract the first two values from 100%. Answer: 17%?
VERY good video - minor nitpick: for the visualization, you had 4 individual months and then one multi--month group. It would have been nice if the Oct-Jan group had used averages on the graph to be more comparable to the individual months
The main fleet carriers were likely the main intended targets for the Kamikazes, as by 1945, both Japan and the US were beginning to recognize and accept how important the Aircraft Carrier was to naval operations, even at the expense of the other vessels. The carriers could allow the fleets to strike farther and inflict damage at distances that a generation before would have required the ships to sail within gunnery range. However, Japan faced multiple problems in addition to things you mention... One that would actually only expand on things you mention would be on ship placement. Even excluding radar equipped picket ships, in the open sea, major ships like the fleet carriers and the battleships would often be at the center of the naval formation. Which would mean any attack, kamikaze or not, would essentially have to go over the entire fleet before getting to the target. And given the size of most warships (even the smaller ones) the formations could still be covering a vast area of ocean, meaning that it wouldn't be like in some video games where all the ships are packed together in a very narrow formation. Thus, an attack on a carrier would draw successive fire from ships at the outer edge of the fleet and then from additional ships as they moved inward... and damaged craft could end up going after other ships if damaged by shots fired because they've lost the integrity to fly on to the intended target. Some parts of this would change when a fleet comes into close proximity to the shore. As in places like Okinawa, the battleships... and potentially even the fast battleships like the USS Iowa, would likely be moved from the heart of the fleet to positions closer to the shoreline to use their main batteries against ground targets. They may still be shielded by other cruisers and destroyers, just as the carriers would be further out... but that would still be a development on much of the base naval formations that would then relate to amphibious operations. Which tactically, if things reach that point, that'd actually raise the importance of the supply and amphibious craft over the carriers as attacking those larger ships would be more with the intention of deterring landings in the first place. For Japan, however, this then presented other problems... as by 1945, the naval air arm and the regular air forces that had been so devastating to the Americans in 1941 to 1942 were long gone. They were starting to run short of planes, short of fuel, and short of trained pilots to fly them. And that training issue would be Japan's biggest worry... even if they had the planes and oil necessary. For, if the pilot is untrained or at least combat inexperienced, the odds of success would be considerably lower than if the pilot is fully trained and has at least survived one or two combat missions. Japan was running out of that and needed away to get as many pilots as possible. And that's where the whole kamikaze idea gained traction, in that a pilot who INTENDS to die doesn't require the extensive training to "dogfight" or line up the right attack run. The pilot just needs to know how to control the plane and find the target. That much lower level of training is bound to have given them trouble as the lower pilot quality would also likely mean that some of their strategic and tactical understanding with regard to what was the most important targets would also be mixed. That would in turn affect how these pilots respond to any and all countermeasures the Americans took.
I had a relative kill by a kamikaze during the war- he’s buried in his home town in Maine. By the way- he was of French descent. Fighting French haters is a full time job.
I find it a little curious that Light Cruisers were statistically the least attacked or the least hit. I'm fairly sure there would have been more of them around than heavy Cruisers, thanks to the 27 ship strong Cleveland class, and theit light and medium AA batteries were a bit weaker than that of Heavy Cruisers.
Erm, 12mm cannon? did you mean 0.50 calibre machine guns which hadn't been considered viable AA weapons for long before 1944, or maybe 20mm cannon which were also out of favour late war, where the 40mm Bofors or for the RN the 2pdr pom-pom were the weapon of the day. That minor quibble aside enjoyed the video and please keep doing what you do :-)
As is correctly pointed out in this video, the Japanese changed their tactics regarding what they considered to be the most effective use of kamikazes. At first, it was decided that American (and, later, British) aircraft carriers should be the primary targets. It was the planes on the carriers that dealt the most damage to Japanese targets. Carriers were a highly combustible mix of ordinance, fuel oil and avgas- and they were very large (though agile) targets. The size of the target was important because the level of training for most kamikaze pilots was abysmal. So, to the Japanese mind, potentially trading one inadequately-trained pilot and one obsolete aircraft for a carrier capable of carrying 70+ aircraft was more than a fair trade. But the carriers were extraordinarily difficult targets. Not only did they possess highly-trained fighter pilots flying up to date aircraft which were vectored via excellent radar onto incoming enemy aircraft, the ships themselves carried very heavy AA weapons. Further, the carriers were ringed with many other ships, all of which were also well-armed with AA weaponry. But there was one other tactic the US used that the Japanese were unaware of, at least at first. Radar was excellent, but it had a limited range. It was standard operating procedure for a carrier group to have aloft a combat air patrol from before dawn to after dusk 9and even at night if there was a night-flight carrier in the group). I think the warning time provided by radar was on the order of 20 minutes, which may- or may not- be enough time to launch additional fighters for defense. So we hit upon the idea of stationing destroyers many miles out from the main battle groups so as to provide earlier warning of incoming hostile aircraft. These were called "Picket" or "radar picket destroyers". The additional alert time these ships provided meant that incoming hostiles would face an even greater number of defending fighters. The Japanese had to reconsider their tactics to include a substantial effort to take out the picket destroyers so as to make attacks on the carriers themselves somewhat easier.
The USN thought process in the Post War because of the Kamikazes was to try to have a standoff high altitude interceptor carrier based fighters, either airborne, ship- or submarine borne early warning radar platform, armored flight deck and better structure for the carriers and lastly and most importantly, ship launched missile (SAM)which the USN spent millions of man hours and tons of money in development and research post WWII.
Denominators are way too low for most of these figures to be statistically significant. One can’t make really ANY conclusions until N=32 at the very least.
The data shows 36% of kamikaze hits were on "other naval ships" That's a big category! And the category apparently excludes cargo ships, plus carriers, cruisers, and destroyers. So what other vessels would kamakazies be diving on?
Attacking capital ships is not the most effective use of a weapon system (unless it is REALLY big or REALLY capable (aircraft carriers or submarines) OR CAC assets. Obviously such targets will be heavily defended. The cold reality of a cost/benefit points to attacking logistics and landing craft. Shaping the battle space.
A little note here that I did not add damage repair as a form of defense as the video focused on countermeasures that prevent a hit - damage repair is something for another video/channel.

Remimded me of the old movie, "Tora-Tora-Tora": the officers were drilling the pilots on their ability.to recognize ships expected to be at Pearl.Harbor. they were quite fast to recoginize the picture but.when an aircraft carrier picture was shown, the pilots were quiet then one memtion a US N aircraft.carrier (I forgot the name). The officer doing the drills jokingly said ( in Japanese) "Idiot, this is your own ship".
Fortunately, they didn’t improve with practice.
@@alexhubble question is how a kamikaze pilot could report his success.
You wonder if maybe they just didn't have enough experience to recognize what a big ship actually looked like. A destroyer would have multiple funnels and multiple turrets all spitting out fire and seem pretty large and imposing, if you'd never actually seen a big ship before you might not realize how much bigger a cruiser or battleship could be.
I think we should add that American Carriers had timber flight decks. The British carriers had armoured steel flight decks. hence the attrition.
My grandfather's Destroyer came under attack by kamikazee multiple times on the picket line at Okinawa they paid those guys special attention
The impact was huge for freedom of movement, too. Even the AAA costs likely exceeded the attacking aircraft significantly and the human life cost was in Japan's favour.
If they'd gotten their tunnel launch sites in the mountains running that 30 mile warning requirement would push the allied ships to at least 50 miles or so from shore.
It's a real pain to deal with Japan's topography too. And the inherent risk running air screens, each carrier landing being quite hazardous, never mind the weather.
I wouldn't say countermeasures were 'effective' but they did everything possible to minimise it- it was still a gigantic morale blow for the sailors. Compared to the u-boat threat this was much more significant and difficult to deal with.
Once you lose more airmen to conventional attacks it only makes sense.
Absent the Atomic Bombs, the Kamikazes may have been more effective in November 1945, when when the invasion of the home islands would have kicked off with Olympic on the island of Kyushu. After the war we discovered:
1. They had correctly deduced where and about when we would land.
2. They had been stockpiling aircraft of all type, from frontline fighters and bombers to cargo and training planes. Including obsolete ones. Basically, anything that could take-off. While many would have been easy prey, Japan had accumulated approximately 10,000 flyable planes for the purpose.
3. Last, but worst, not least, they had a new strategy. Recognizing that attacking warships bristling with guns of all types had failed completely against the Battleships, Fleet Carriers and Cruisers that made such attractive targets they were NOT going to even try. Instead the new plan was to go after the troop ships. Even easier to sink than destroyers they contained the very men who were to land on the home island.
My father was going to be on one of those troopships.
It's doubtful they had the fuel to use those kamikazes.
@@WALTERBROADDUS Or the pilots.
@@gwtpictgwtpict4214 they had though. They specifically were preparing for it...
@@M1903a4 my dad, after serving in Germany, had actual battle maps for invading Japanese occupied China. Such maps had a little number at the top for estimated casualties, often a single digit number like 4.0. This number was 40. A typo? He asked? No
Practice makes perfect!
Fantastic video! The only major point that needs to be considered is that while sinking a ship is clearly the desired outcome, and a hit is certainly sub-optimal, ultimately a mission-kill that neutralises the vessel is a key factor. If that vessel is out of the fight, it doesn't really matter if it is at the bottom of the ocean or being towed back to Uluthi or Pearl or San Diego. And particularly with the destroyer example, a DD hit by a kamikaze, even if not sunk, is almost always going to be completely hors d combat. Similarly while a hit is a useful metric for strike-rate effectiveness, but we only have to think of the darkly funny picture of the poor guy who tried to hit HMS Sussex and left nothing more that a looney toons imprint on the armour plate.
Kamikaze were effective when it came to create panic in aircraft carriers and other ships crews. Also using Nakajimas Ki-84 Hayates as a kamikaze was sheer stupidity and a waste of a good airplane!

Ain't no spray, gel, or wax that can control this hair.

Great video as always. Very informative but it raised my curiosity. The Essex class had nominally 12*5 inch guns as heavy AA defense and those were the first line of ship self defense. How did the British carriers fare in that department? They had 16*4.5 inch guns with much of the same range and performance.
Also, did the asymmetrical placement of the Essex 5 inch guns a factor in how the ships maneuvered to get the most guns to bear? I know it's a rabbit hole, but on the tactical level defending the ships, those questions must have had an influence.
Another excellent video.
One thing I've been wondering about, so often I've heard people say that kamikaze were a tactic of pure desperation. On the other hand I heard from somebody who had actually studied the use of kamikazes that there was an actual pragmatic approach to the use of kamikaze - that losses of aircraft and pilots in conventional use were so high, that it mathematically, if one out kamikaze actually hit a ship, more damage for ten aircraft and pilots was inflicted than if the ten were lost without inflicting any damage.
Do you know of any such statistics?
This analysis is correct. When they switched to these tactics, their success in regular c*mbat was extremly low, because of being outgunned and outclassed at this point.
So yes, the Kamikaze did indeed more damage than would have been done if they would have fought conventionally.
Ian Toll writes about it in his Pacific Crucible trilogy.
@@wedgeantilles8575 But I mean specifically, effectiveness per lives lost. The assumption is that in conventional warfare _some_ pilots will return, whereas with kamikaze, almost no pilots will return - yes, some did turn back because of mechanical failure, like engine problems, and land, but I imagine those were few and far between.
@@DerOrso During this time of war, not that many pilots returned anyway.
They were running out of skilled pilots fast and green pilots got sl**ghtered out there.
Kamikaze had the additional benefit, that you could achieve more with limited skills.
Hitting a ship with torpedos or bombs was very difficult.
@@wedgeantilles8575 Very true. Trying to deliver a munition is such a way that you 1) have a good chance of hitting, and 2) have some chance of getting away, is harder than just "aim for the boat".
The more one looks at the situation, the less crazy is sound. And when you consider, all Japan really wanted, overall, was to be included in the colonizing nations, like Britain, France, Holland, Portugal, Germany, and the US, and not be colonized like China. There were only the two choices, because the known colonizers always came and colonized every nation with exploitable resources they could; no exceptions.
When you consider that only 90 years prior, Japan looked more like 17th century Europe, or even older, with only very limited technology, and 90 years later they actually lead the world in naval aviation, the most technologically advanced form of warfare in existence at the time. And all that because they were certain, they didn't want to be colonized.
Excellent, as always.
Not only are the DD's on the outer pickets, hence the higher numbers of Kamikaze attacks on them, but they are also much more numerous than BB's and CV's. A battle group would consist of roughly 15 flat-tops (CV, CVL), 8 BB's, 15 cruisers, and 75 dd's.
You missed another escort carrier hit by Kamikaze. The USS St. Lo was also hit by Kamikaze. Skynea history did a great video about it.
@@darkusblader Not at Okinawa, though.
If games like War Thunder are in any manner comparable to real air warfare, I'd imagine kamikaze attacks are the closest, as the players aren't usually interested in surviving the attack as long as they get a hit.
Having played such attacks against enemy fleet, I also notice the tendency to attack the first ship that spots the plane, simply because from the point you're spotted onwards, you're basically on borrowed time - even if you managed to survive the first ship's AA, you very likely won't survive the entire fleet others who are very aware of you by this point and will shoot you into pieces if you get anywhere near.
And yes, I know real air attacks weren't most of the time done with individual planes, but on the other hand, hitting the nearest ship may increase the chances of your squadmates getting past it. Or that's what one would think intuitively, at least.
Armored flight decks came In handy for the UK carriers, any chance you can do a bit about there role?
I believe the armored decks came about more as an acknowledgement that carriers of the time may have little warning to respond to an attack, and if they’re operating in the Med then they’d have to contend with land bases operating more and heavier aircraft on a continent instead of carriers and island airfields.
The downside was their lower hangar height which limited what aircraft they could operate and thus their value as a carrier.
@@classifiedad1 Indeed. I believe there was an American naval officer serving as liaison to the Royal Navy. Regarding kamikazes he said something to the effect of, if an American carrier takes a kamikaze to the flight deck, it's six months in Pearl Harbor. If an RN carrier takes a kamikaze to the flight deck it's "sweepers, man your brooms."
Different ships, built under different doctrines, fighting a war they probably weren't designed for. You fight with what you've got, not what you want.
Another wartime lesson about the kamikaze and the 40 mm Bofors: post war the USN began replacing the 40 mm with the advanced 3”/50 MK 22 on mounts MK 27, 33 & 34. The conclusion was the kamikaze had to be smashed into bits a task a single or so 40 mm and smaller shell could not do. Like a guided mission today, a kamikaze wasn’t aff3cted by the psychological effects of tracers flying by. The 3”/50 shell was the smallest that at the time could carry a VT fuse. (Today 40 mm shells can be fitted with multi function fuses and the 40 mm today can be fitted in unmanned, fully automatic mounts such as the OTO-Breda 40/70 Fast 40 twins.)
As for the famous 20mm Oerlikon the saying was, “when the 20s open fire it’s time to brace for impact.”
07:52 Please stop giving me book recomendations. My Bookshelve is already overloadad and can only take so much! :)
I was going to add a comment, but all the good ones were taken. And, this is a good video.
How do these numbers change when you include the UK and commonwealth BPF ships in the data? As the UK aircraft carriers had armoured flight decks they were often used closer inshore.
3:25 Yeah, I was never the most well read about the Kamikaze attacks, but just from seeing general history, it did seem Destroyers bore the brunt of the attacks despite Capital Ships being the preferred targets. Carriers especially were what Japan were most worried about yet they were among the least to be attacked. I also know the USN even made it a point to push Destroyers out far away on Radar picket duty with Fighter Caps. Kamikazes were drawn towards them. This was acceptable to the US Navy because the Carriers were so valuable while the service had more Destroyers. Not to mention Carriers and Battleships tend to be in the center of USN air defense formations. So Kamikaze would have to deal with Fighter Caps, layers of Anti-Aircraft Fire, and then MAYBE get a shot to make a run against a Capital Ship.
Also understandable that Kamikazes had good hit rates against Escort Carriers. They were small, cheaply made for fast construction and very slow. They would not have been bristling with AA guns compared to the larger, more heavily defended Fleet Carriers like Enterprise, Saratoga, and Essex-class. Even the Independence-class Light Carriers didn't fare badly like the CVEs because they were faster and had better AA guns, i.e. more 40mm Bofors than the Escort Carriers that tended to have lighter, weaker, shorter ranged 20mm Oerlikons.
Worsening Kamikaze success rates as time went on is understandable. No matter the conflict your enemy is actually rather smart and will figure things out and get better.
Excellent, you cleared up a lot of myths, and vagueness on the subject for me.
Proximity fuse "qoute: How effective is the proximity fuse?
The proximity fuse proved three to four times more effective than conventional time fuses, and night kill-ratios increased by 370%. In 1943, naval guns fired 36,370 antiaircraft rounds. Although only 25% used proximity fuses, these accounted for 51% of the kills.
Thanks from Canberra Chris. 🇦🇺
The K-pilots were instructed to not target battleships or cruisers because their armor made them immune to serious damage by the slow flying planes.
Many K-pilots flew multiple missions when they failed to find USN ships. That is one reason a substantial number survived the war. Dairies and post war interviews show many of the men knew their efforts were futile and flew the missions only because of intense pressure.
16:18 Music is drowning out your words. Could not understand what percentage hit targets; had to do math to subtract the first two values from 100%. Answer: 17%?
Confirm 17%
VERY good video - minor nitpick: for the visualization, you had 4 individual months and then one multi--month group.
It would have been nice if the Oct-Jan group had used averages on the graph to be more comparable to the individual months
Good point!
A most informative video.
Great video :) I was looking for your HMS Belfast one but couldn't find it, have you got a link?
The main fleet carriers were likely the main intended targets for the Kamikazes, as by 1945, both Japan and the US were beginning to recognize and accept how important the Aircraft Carrier was to naval operations, even at the expense of the other vessels. The carriers could allow the fleets to strike farther and inflict damage at distances that a generation before would have required the ships to sail within gunnery range. However, Japan faced multiple problems in addition to things you mention...
One that would actually only expand on things you mention would be on ship placement. Even excluding radar equipped picket ships, in the open sea, major ships like the fleet carriers and the battleships would often be at the center of the naval formation. Which would mean any attack, kamikaze or not, would essentially have to go over the entire fleet before getting to the target. And given the size of most warships (even the smaller ones) the formations could still be covering a vast area of ocean, meaning that it wouldn't be like in some video games where all the ships are packed together in a very narrow formation. Thus, an attack on a carrier would draw successive fire from ships at the outer edge of the fleet and then from additional ships as they moved inward... and damaged craft could end up going after other ships if damaged by shots fired because they've lost the integrity to fly on to the intended target.
Some parts of this would change when a fleet comes into close proximity to the shore. As in places like Okinawa, the battleships... and potentially even the fast battleships like the USS Iowa, would likely be moved from the heart of the fleet to positions closer to the shoreline to use their main batteries against ground targets. They may still be shielded by other cruisers and destroyers, just as the carriers would be further out... but that would still be a development on much of the base naval formations that would then relate to amphibious operations. Which tactically, if things reach that point, that'd actually raise the importance of the supply and amphibious craft over the carriers as attacking those larger ships would be more with the intention of deterring landings in the first place.
For Japan, however, this then presented other problems... as by 1945, the naval air arm and the regular air forces that had been so devastating to the Americans in 1941 to 1942 were long gone. They were starting to run short of planes, short of fuel, and short of trained pilots to fly them. And that training issue would be Japan's biggest worry... even if they had the planes and oil necessary. For, if the pilot is untrained or at least combat inexperienced, the odds of success would be considerably lower than if the pilot is fully trained and has at least survived one or two combat missions. Japan was running out of that and needed away to get as many pilots as possible. And that's where the whole kamikaze idea gained traction, in that a pilot who INTENDS to die doesn't require the extensive training to "dogfight" or line up the right attack run. The pilot just needs to know how to control the plane and find the target.
That much lower level of training is bound to have given them trouble as the lower pilot quality would also likely mean that some of their strategic and tactical understanding with regard to what was the most important targets would also be mixed. That would in turn affect how these pilots respond to any and all countermeasures the Americans took.
I had a relative kill by a kamikaze during the war- he’s buried in his home town in Maine.
By the way- he was of French descent. Fighting French haters is a full time job.
I find it a little curious that Light Cruisers were statistically the least attacked or the least hit. I'm fairly sure there would have been more of them around than heavy Cruisers, thanks to the 27 ship strong Cleveland class, and theit light and medium AA batteries were a bit weaker than that of Heavy Cruisers.
Erm, 12mm cannon? did you mean 0.50 calibre machine guns which hadn't been considered viable AA weapons for long before 1944, or maybe 20mm cannon which were also out of favour late war, where the 40mm Bofors or for the RN the 2pdr pom-pom were the weapon of the day.
That minor quibble aside enjoyed the video and please keep doing what you do :-)
As is correctly pointed out in this video, the Japanese changed their tactics regarding what they considered to be the most effective use of kamikazes. At first, it was decided that American (and, later, British) aircraft carriers should be the primary targets. It was the planes on the carriers that dealt the most damage to Japanese targets. Carriers were a highly combustible mix of ordinance, fuel oil and avgas- and they were very large (though agile) targets. The size of the target was important because the level of training for most kamikaze pilots was abysmal. So, to the Japanese mind, potentially trading one inadequately-trained pilot and one obsolete aircraft for a carrier capable of carrying 70+ aircraft was more than a fair trade. But the carriers were extraordinarily difficult targets. Not only did they possess highly-trained fighter pilots flying up to date aircraft which were vectored via excellent radar onto incoming enemy aircraft, the ships themselves carried very heavy AA weapons. Further, the carriers were ringed with many other ships, all of which were also well-armed with AA weaponry. But there was one other tactic the US used that the Japanese were unaware of, at least at first.
Radar was excellent, but it had a limited range. It was standard operating procedure for a carrier group to have aloft a combat air patrol from before dawn to after dusk 9and even at night if there was a night-flight carrier in the group). I think the warning time provided by radar was on the order of 20 minutes, which may- or may not- be enough time to launch additional fighters for defense. So we hit upon the idea of stationing destroyers many miles out from the main battle groups so as to provide earlier warning of incoming hostile aircraft. These were called "Picket" or "radar picket destroyers". The additional alert time these ships provided meant that incoming hostiles would face an even greater number of defending fighters. The Japanese had to reconsider their tactics to include a substantial effort to take out the picket destroyers so as to make attacks on the carriers themselves somewhat easier.
The USN thought process in the Post War because of the Kamikazes was to try to have a standoff high altitude interceptor carrier based fighters, either airborne, ship- or submarine borne early warning radar platform, armored flight deck and better structure for the carriers and lastly and most importantly, ship launched missile (SAM)which the USN spent millions of man hours and tons of money in development and research post WWII.
Thank you
By attacking the defending ships they hoped to make more guns fall silent & open the way for more damages! IMO
Denominators are way too low for most of these figures to be statistically significant. One can’t make really ANY conclusions until N=32 at the very least.
The data shows 36% of kamikaze hits were on "other naval ships" That's a big category! And the category apparently excludes cargo ships, plus carriers, cruisers, and destroyers. So what other vessels would kamakazies be diving on?
A mix of DE, DM, DMS and LSTs et al.
Kamikaze tactics could have worked really well with veteran pilots.
Attacking capital ships is not the most effective use of a weapon system (unless it is REALLY big or REALLY capable (aircraft carriers or submarines) OR CAC assets.
Obviously such targets will be heavily defended.
The cold reality of a cost/benefit points to attacking logistics and landing craft.
Shaping the battle space.
It depends :)
