I actually saw one of these in the early 1990s at the Maritime Museum in Tokyo. It was immense. How they got it into the building must have been a huge job. Unfortunately, the plane disappeared a few years later. The museum is now closed due to the passenger ship terminal taking over the area. I assume that the museum will open at some future date, somewhere. Hopefully, the plane will resurface then.
That sounds ominous when the museum was by the water and you hope the missing plane will "resurface!"
That might have been the H8K, not the H6K.
@@Quadrenaro you might be right. It was a long time ago. Anyway, that flying boat was huge. Wish I took a pic of it.
I would imagine if it was transported by road, rail, or ship it has already been partially disassembled. Wings, tail, fuselage units, etc.
I preferred the Sunderland
I like that you showed the distance visually. It is one thing to hear the numbers but seeing it on a globe makes them impact.
Most WW2 Aero historians rank the Kawanishi H8k Emily, the successor to the H6, as the premier flying boat of the war, with the longest range, endurance, robust construction & defense of any flying boat. This is exceptional as the completion was extraordinary considering the British, German & American flying boat models. The only down side of the Emily was it’s lower production rate.
"Premier flying boat of the war"....no, just no. The Short Sunderland was a beast of a flying boat and would outrange and outcarry anything this can do. The thing had toilets, a kitchen and a whole host of other innovations.
@@mikeycraig8970 According to Flying Boats, Volume 5, by William green, the H-8 Emily had 4 ea 1,850 HP engines, vs 2,200 in the Sunde, max speed Emily 290 mph vs 207, range Emily 3,800-4,440 vs 2,690 Sunde, armament Emily 5 20 mm cannons + 4 mg & 8- 550 lb bombs vs 8 mg & 4,000 bombs in Sunde. The Emily’s hydrodynamics were superior allowing landing in a sea state 5 vs 4 for the Sunde. So as you can see the H-8k Emily clearly dominated, however the Emily was launched 3 years after the Sunderland & much fewer were made
What is trully amazing is that Kawanishi still manufacture remarkable flying boats today!. ShinMaywa is the direct descendant of Kawanishi and its flagship today is the US-2 for the Japanese Maritime Self-Defense Forces.
The US-2 is a beast. The ultimate high tech flying boat at maritime recon, anti sub-and SAR.
@@rednaughtstudios And fuxking expensive!!
@@uryen921 True
@@uryen921 Everything is expensive these days and anything military related is even more expensive. Make it a flying boat with a limited production run and market and things get stupid expensive. However having said all of that, in terms of the SAR capability, once found by a flying boat you can expect to be rescued whereas other SAR aircraft have to stooge around as long as possible while a ship comes to your rescue. Which would you rather?
Which basically is an ultimate development of a Martin Marlin, used by Japan in earlier days.
Great to see a video about this big boy. It's quite seldom talked about.
Definitely.
Big gal NOT boy this is the 2020s - ya know ;-)
The Seaplanes of the 20's and 30's were beautiful things.
Love how you always do videos on some of my favourite aircraft :)
Crazy to see you here.. and to find out you ALSO like the H6Ks like i do lol
damn smigol is in it 2 niceeee
Cant wait to see you outdogfight people with this absolute unit
Thank you! 😎
In August 2017, 75 years after they were strafed and sunk in Guadalcanal Campaign, my friends and i scuba-dived on two Mavis wrecks off Tulagi, Florida Islands. These wrecks were 30-35 metres deep and one the 'No 2 Mavis' is the most intact left in the world, just minus the outer starboard wing and one engine. Some machine guns, recon cameras and the 20mm cannon still remain on site. In the fuselage behind the tail-gunner position lived a medium-sized brown-spotted grouper. I've since completed an A1-sized watercolour painting of this wreck.
H6K and H8K are some of the best looking flying boats ever.
I also recommend having a look at the Dornier Do24 and Do26. Those are seriously sexy flying boats as well.
Yes, DO-26 is a very attractive plane
My favorite flying boat is still the PBY Catalina. Long range patrol, anti-submarine, search and rescue, anti-shipping, and even night attack (the Black Cats). She was an extremely versatile design.
For a seaplane it was attractive,that’s for sure
Yeah it got used in many roles , but most seaplanes of the time did. Had terrible handling and flew like a truck according to all accounts I have read and heard. Met a dude in Seattle yrs ago that flew one on patrols in the Pacific in WWII and he said it was exhausting to fly ling missions because you had to keep hand and foot pressure on controls at all times. If you relaxed grip for just a bit it would start to go out of control pretty quickly. Hard to fly. He liked the Mariner much more
Many people are surprised to find out how heavily armed some of these Pacific Theater "flying boats" were. The PBY was, indeed, difficult to fly, requiring a constant state of vigilance on the part of the pilot, but made up for that by packing a punch with it's pair of forward firing .30 cal. machine guns, a pair of .50 cal. waist guns, another .30 cal. firing rearward, and the ability to carry two tons of various bombs, torpedoes, depth charges, or combination thereof. It was one angry goony bird in its day, its lack of speed offset by the ability to spend 20 hours in the air.
@@lordphullautosear true
Let us pause for a moment to salute the hardiness of the nose gunner/bombardier. Sitting out in the open air, in the most exposed position you could think of, for hour upon hour
Thank you for this excellent video. I enjoyed learning about this important aircraft.
My favorite is the PBY maybe it wasn’t the biggest or best , but it was the workhorse of the US and Commonwealth Navys and even saw service with the Soviet Union.
H8K. Although the PBY is a classic twin, the H8K was a well designed war machine.
The way wars are fought was changing, forging ahead; leaving a lot of fondly held concepts in its wake. The floatplane fighter. The flying boat. The twin engine torpedo bomber.
It was so much easier to build an airfield and unload planes on the tarmac, than it was to laboriously transfer cargo from plane to barge to shore to trucks for distribution.
Do I think the Boeing 314 best represents the romance of the Age of Flight? Absolutely . . . for a thousand USD per ticket. That'd be, like, $20,000 today.
Otherwise, the H8K is, in my view, the most beautiful bit of functional art the war produced.
Thank you for your research and work. My first seaplane love is the (fairly well covered) Catalina, but my second has always been the Mavis. Both were so elegant and effective! Nicely presented!
⁰pp ok

Your survival chances were much better in the PBY.
What about the Short Sunderland !? 😊
You've convinced me of her beauty! Thanks for your doc and review; she was new to me.
Out of all parasol wing flying boats ever built, the Mavis is the most graceful. A perfect beauty. It's huge range and reliable technology made it useful as a transport until the very end.
The Emily is impressive in every possible sense. The Allies were rather lucky that it was never licence built in Germany, replacing the slow Fw200 and the unreliable He177 in recce and anti shipping roles over the Atlantic ocean.
Even more fortunate is that the Germans or Japanese did not think to adopt the A6M2-21 for German use. It would have been available already at the time of the Battle of Britain. And that would have solved the German problem of not being able to escort bombers deep into Britain with an effective fighter. The Me-110 was not sufficiently maneuverable to take on even second line British fighters. It is likely the Germans would also have solved a problem the Japanese had with the Zero, that the radio did not have sufficient insulation, and did not work well in practice. That made Japanese aerial combat uncoordinated.
It looks quite similar to the Dornier DO24, which is my favourite being designed after specifications for use in the Dutch East Indies. I read somewhere that this similarity once led to the AA on a Dutch ship not being used against the attacking Mavis because the crew members misidentified the plane(s) for being DO24K's.
You didn't know it was based off that design? Lol. Weird since you called it your favorite plane.
@@loveofmangos001 Highly doubt it was based or copied from Dornier. Just because it uses a somewhat similar configuration doesn't mean it's influenced by it.
Besides...
It looks far too different for that.
Just look at the signature Dornier "boat-section" from the Do24 which is nothing like the Mavis.
@@Leon_der_Luftige obviously you've based that entirely on assumption.. Dornier designers (and a few other prolific German designers helped Japan, hence all the under license copy's of various Aircraft in the early days of Japanese aviation.
The Do 24 was a trimotor though.
@@liamwedlake9820 Do you realise, the Mavis first flew 1936 and the Do24 1937?
By your Logic, the Spitfire is "copied" from the Germans and the P47 "copied" from the Italians because of the elliptical wings.
You give way too little credit to the designers.
Great Video, Thanks for sharing !
H6K's final mission was to transport 2 tons of banknotes guaranteed by the Bank of Japan to Taiwan, where the economy had collapsed, in September 1945, shortly after the war ended. The H6K fuselage was painted white to remove the Japanese nationality mark and replaced with a green cross mark. The pilot for this important mission was Toshinari Koshida, who had successfully rescued 40 people stranded at the Davao Air Base in Mindanao with a H8K and received a letter of appreciation from the Japanese Navy during the war.The transportation was completed, and Japan and Taiwan still have important economic and military ties.
The MARS flying boat is my favorite. I have the H6K model kit by Hasegawa and big even in 1/72 scale.
My co-workers grandfather shot one of these down near New Guinea. Amazing.
I was in the plane he shot down, whats his phone number, i want a word with him.
Wonderfully edited and presented as always!
Thank you! I have been enjoying your content also! Keep up the good work.
Intresting aircraft, but think the Sunderland was more superior in all the important areas.
Sunderland for me
= graceful and stylish in appearance?
@@dallesamllhals9161 = Seriously ? Who REMOTELY gives A.F ?
Being [Quote] "graceful and stylish" DOES NOT equate to sinking U-Boats
Also, this....
2nd June 1943 = "N-Nuts", 461 Sqdn RAAF Sunderland airframe 'EJ.134'
Takes on no-less than EIGHT as in EIGHT heavy fighter cannon Ju.88-C 's
Spends the next 45-mins being attacked, 25 separate attempt/attacks...
Shoots down no less than THREE of it's attackers AND drives-off the rest
Sunderland EJ.134 returns to Wales - KG.40's Ju88's are "humiliated"
Gains the nickname "Fliegendes Stachelschwein" = ("Flying Porcupine")
There is NOT a single PBY Catalina that can match that, in "hardness"
BTW ; Whilst I do "like" & "love" the Catalina - (I've x 9 unbuilt, in 1/48th)
So you can shove your "graceful & stylish" where the sun don't shine !
I'm with Rod = Short Sunderland all the way = Hard A.F
Give me the 'sledghammer' Short Sunderland, all day long instead.
A great presentation of a classic flying boat! May I point out that from 8:46 to 8:54 in the video, the photo shows an Emily and a code name "Cherry", H5Y1. The full designation would be Naval Aero-Technical Arsenal Type 99 Medium Flying Boat (H5Y1-2). The aircraft shown in this photo actually shows the 31st H5Y built, in civilian colors as J-AAMG of Dai Nippon Koku (Greater Japan Airlines) which was fulfilling "meteorological observations" for the IJN. The photo was taken off Negishi, Yokohoma in June 1944, per my source, Japanese Military Aircraft Illustrated, a Koku-Fan Illustrated Special, published by Bunrin-do, Co., Ltd.
This is what happens when you work late at night, you end up mistaking a four-engine aircraft for a smaller twin-engine. You seem to know a lot about Japanese planes! Thank you very much for the correction, I'll add it to the video's description. 👍
@@AllthingsWW2 I spotted the civil registration numbers in huge letters across the wing, THEN saw the twin engines. I am a modeler, and had started a conversion of the Hasegawa 1/72 Emily to that Cherry years ago. I do have an affinity for the flying boats. Dan
It has to be noted, that the design look like Dornier Do 24 with a fouth engine, not a Short design. AFAIK Kawanishi worked together with Rohbach / Dornier before producing the H6K.
Thanks!! It is a beautiful aircraft!!
Good to see you back countryman! A classic of earlier Japanese military doctorship thinking, a flying gasoline bomb. As you pointed out they learned their lesson later with the Emily. Good video!
Obrigado e um abraço!
Excellent video and info!
Thank you!
This was an outstanding video. WELL DONE...
Thank you!
Amazing video....Thanks very much....

One of the best videos yet. Keep it coming
Thank you!

Long time ago I knew a Modelmaker who turned out a Mavis..it was perfection along with his builds of Japanese Warships and Aircraft..
Great video, ty ❤
Thank you!
Good Video/Info.
Thank you for this excellent production I have subscribed
Thank you and welcome!
My favorite flying boat would be the biggest size of Dornier wal. Such a beautiful plane I would love to have something like it today. I wouldn't touch an original but I'd love to build a replica. Have it built for comfort and rugged exploring with a couple of turboprops on top!
My favorite is the Dornier Do 26, a very elegant aircraft with an incredible range.
My favorite WW2 seaplane: USN PBY5 Catalina - amphibious, and often the Air Search & Rescue in the Pacific Campaigns. Plus, it's the on LtCol Boyington went on about 40 years on....
Plus, I have seen one flying...
My favorite seaplane outside the WWII era is the DHC-2 Beaver. I've flown 3 different beavers (N-5142G, N-5342G, and N5143G), and 5342G was on floats at the time. Depart ANC, T&G's at D72 (Fire Lake), mid-air seat swap, while the IP/CFII has the others do T&Gs. ... I took most of my flight instruction in N-5142G. They served 50+ years each, first in the military, then in CAP...
My favourite Ambitious aeroplanes are Piagio P.166 Royal Gull, followed by Gruman Mallard & Albatross
Great job thanks
Idk how to answer about my most favorite flying boats. I guess the most beautiful, and a lot of people do agree with me, is Latecoere 631. Most respectful, hmm... it can be in equal range Short Sunderland, PBY and many others, very difficult to choose. But for this time, not a period of WW2, we also have some big flying boats in service, 4 in total: ShinMeiwa, de Havilland Canada CL215/415/515 (last one is only a project but design and roles are quite similar as of the elder planes), Chinese AG600 and Beriev Be-200. I guess the most beautiful of them is the last one.
Short Sunderland
As per my reply to 'Dalle' in Rod's comment, above
2nd June 1943 = "N-Nuts", 461 Sqdn RAAF Sunderland airframe 'EJ.134'
'Nuff said !
I've always had a crush on the Supermarine Walrus
Great video.
Thank you!
I've always found the giant Saunders-Roe Princess flying boats a very sad story; I used to see them in mothballed state from the River Solent in the 60's when I was a kid.
Love your videos man.
Thank you!
My favorite flying boat would be pby and the Grumman goose
Short Sunderland and Catalina. Very interesting video.
Great video, thanks. Reminds me of the phrase, The bigger they are, the harder they fall.
well done. very interesting video.
Thank you!
Great video, thank you! I've been flying the H6K4 in War Thunder and thought it had some striking similarities to the Short Sunderland, now I know why 👏🏻
It needed a 20mm ball turret on front, top, and bottom. 2,000 HP engines. Samurai, pilot and co pilot.
Thank you for doing this aircraft! It's very underrated I hope you will consider doing more flying boats like the bv222 viking
^ 222 = PRETTY? 😲
Oh yes, the BV 222 will be a thing in the future. :) Thank you!
My favourite seaplane? The Catalina, these planes are still in service fighting bushfires.
Beautiful bird! First time I have come to know about it.
My favorite flying boat is easily the PBY. They were everywhere and did everything
A f.... smart plane especially the last version
My father flew Cat's out of Ceylon, RCAF 413 sq., the thumbnail caught my attention because of the resemblance to the Catalina. I knew that a lot of Japanese aircraft of that era were heavily influenced by Western aviation.
Kawanishi H8K and the Short Sunderland are a good example.
I like the look of it, with the slow curve from nose to tail.
Quite attractive, and a good aircraft in places without bullets ~
Definitely a good looking plane !
(That I hadn't heard of before)...
Cheers from Iceland 🇮🇸

Great video! My favourite flying boat is the supermarine walrus
Great illustrations
Nice video
For me the Shorts Sunderland is my favourite flying boat.
Excellent
My favourite flying boat is precisely the H6K. It looks like a lizard under a parasol wing
Thank you for your video.
I am fond of the China Clippers...
Not made by Winnie the Poo' are they now 😛
Thank you!
NC-4 has been my favorite since first learning flying boats were a thing.
I dig the the nose painted black on top for the windscreens, issa bute!
You definitely should make an episode on the Nakajima Ki 84 "Hayate", the best Japanese piston engine aircraft made during the war :D
Hardly gets mentioned because of the A6M "Zero". Most of the fighting in the Pacific that people always feature is carrier based aircraft. However if an airbase had the Ki 84 you were in for a hell of a time.
It's in the works. I'm waiting for some good material to do it justice. Thank you for the suggestion!
Favorite flying boat, any of the Lohner models from the Austro-Hungarian Empire in the Great War.
My favorite flying boat is the Consolidated PBY.
My favourite Japanese aircraft of WW2. Nice video, with good information.
Thank you!
The Mavis and Emily are great aircraft, as long as there is no enemy opposition.
Gasp! My beloved!
My favorite flying boat? The PBY Catalina.
A very handsome flying boat, I wish i could see one. Was that a fabric covered fuselage ?
Good-looking flying boat.
I've always liked the Lake Amphibian, but that is of course not in the same class as this flying boat. For sheer size, the Martin JRM Mars is pretty cool! Going down in size, the Martin P5M Mariner is nice, and on the lower end, the Consolidated PBY Catalina rounds out my choices.
I love flyingboats and my number 1 has to be the Short Sunderland 'Flying Porcupine'
I have a soft spot for the Martin Mars. Probably because I flew in one from Hawaii to San Francisco when I was two weeks old. I was an experienced air traveler by then having already flown from the Marshall Islands to Midway and then on to Hawaii in a C 47.
I was conceived in the Spruce Goose.
@@marcfitzhenry7581 delivered on Midway.
Baron von Munchhausen?
India has received, a few of these, flying boats, their descendants, that is ,for maritime patrolling
@@pratapbalakrishna3036 Too funny! My father was career Navy and he was stationed in the Marshalls after the war. The Navy allowed my mom to join him there and so...
Love this beauty
favourite PBY
Favorite flying boat? Probably either the Sikorsky VS-44, Boeing 314, or Spruce Goose.
This plane and some of the Dorniers were the apogee of flying boat design.
I knew about the Emily (which I compared with the Short Sunderland) but this programme on the Mavis has been very interesting. PS I find the American emphasis on both words of 'flying' and 'boat' somewhat disconcerting and modern British parlance appears to be copying it. For those who knew flying boats, we pronounced it as one word, with no emphasis on 'boat'. has anyone else noticed this?
I'm STILL trying to get my head around it.....**
How Americans have managed to 'Bastardize' the word "Route" into "Rowt" ?
The famous song is "Get Your Kicks ON ROUTE 66" = not effing "ROWT"
Insane !
My favorite has always been the good old Catalina.
It indeed is a beautiful flying boat. I'd love to have a 1/72 scale model of it, but I don't have room for it, because it is so huge!
Favourite? For Lottery win availability, elegance & overall practicality, the PBY Catalina. For sheer grace, the DO24 : )
Thank great work. Love PBY Catalina , but wondered why they never made a 4 engine version?
The U.S. Navy all ready had the four engined PB2Y Coronado made by the same manufacture, Consolidated.
en.wikipedia.org/wiki/Consolidated_PB2Y_Coronado
They did. Consoladated built the 4 engined Corranado. I believe the navy called it the PB4Y. It was expensive to build and was used mainly as a transport/medical evacuation plane. Martin also built the gigantic Martin Mars. Only a handful of these monstrous flying boats were built and are still in service used as giant water bombers to fight forest fires in Western Canada.
@@jollyjohnthepirate3168 BUT is the Martin Mars elegant/graceful or (just)impressive? ;-)
Me too. There seemed to be room. I never understood why they never put flaps on them either.
@@jollyjohnthepirate3168 and they're getting pretty old. I heard they have scapped a few for parts. Dunno how many are still airworthy. I think only 3 or 4.
The H8K is THE premier flying boat of WWII.
I vote for the JRM Mars, from Martin.

Japan made some really great WW2 aircraft . But, they never prioritised armour, strength, redundancy or fuel tank sealing.

Sweet aircraft.
If I'm not mistaken they used several of these during the Aleutian campaign and a couple were lost
Great video, thanks!
Any chance of getting the same for an H8K
..pretty sure - it'll come.
Yes, the H8K will be covered, but not anytime soon. Obrigado!
Favorite Flying boat.. Let's see BV 222 or BV 238! Are there any other choices?
