Hiro Naval Arsenal - The Forgotten Pioneer of Japanese Flying Boats

[@RexsHangar]

F.A.Q Section Q: Do you take aircraft requests? A: I have a list of aircraft I plan to cover, but feel free to add to it with suggestions:) Q: Why do you use imperial measurements for some videos, and metric for others? A: I do this based on country of manufacture. Imperial measurements for Britain and the U.S, metric for the rest of the world, but I include text in my videos that convert it for both. Q: Will you include video footage in your videos, or just photos? A: Video footage is very expensive to licence, if I can find footage in the public domain I will try to use it, but a lot of it is hoarded by licencing studies (British Pathe, Periscope films etc). In the future I may be able to afford clips :) Q: Why do you sometimes feature images/screenshots from flight simulators? A: Sometimes there are not a lot of photos available for certain aircraft, so I substitute this with digital images that are as accurate as possible. Feel free to leave you questions below - I may not be able to answer all of them, but I will keep my eyes open :)

[@lorenrogers9269]

Staying with the aquatic theme then, would you consider adding the highly unusual Goodyear GA-33 Inflatoplane to your list of aircraft you intend to cover?

[@Niels_Larsen]

Would an analysis of a fictional aircraft (inspired by real ones), ever be on your list of potential video topics?

Inside Kure's Yamato Museum, Hiro is part of Kure, there is a wall of models depicting all the aircraft produced by the factory and the factory history is also shared. If you want to see a depiction of the arsenal, the animated movie In This Corner of the World features it throughout as the protagonist's father in law is an employee. It even accurately depicts some of the arsenal bomb raids and Kure's colorful flak bursts, which are something that made it into B-29 bomber crew logs.

Some beautiful designs here. I love flying boats. Thank You, Rex.

[@terrysmith7751]

Very interesting. Aircraft evolved so quickly between the wars that I'm surprised any designs managed to be produced in numbers.

[@emjackson2289]

You say that, yet the Hurricane, the Ju-87, the Wellesley et. al. all inter-war planes

[@edsutherland8266]

That’s why there’s an argument that the 1930s rearmament had to be relatively ‘late’, otherwise the RAF would have started the war with a huge force of Hawker Harts & Hinds! By starting a bit later, they were able to start the buildup with the likes of Hurricanes (okay, and Fairey Battles etc…) and others.

[@elgato9445]

Excellent content on Japanese flying boats! The Kawanishi was always a favorite of mine.

[@eastindiaV]

I love airplane blueprints. As a kid it just blew my mind that all these different military planes from this book I had just started as drawings. Same with their engines, and the angles of the airframe, etc.... it was all some guy with a pencil and paper, and maybe some simple mathematical knowledge... there is always help from technicians, of course, but at that point you're manufacturing the thing.

[@grantsmythe8625]

I know this has been the "Jet Age" since 1945 but the old prop planes, they're just beautiful works of art. Today's planes are almost without art. Function now rules the air.

[@anzaca1]

Function has always ruled the air, actually. Planes we consider beautiful look that way because of aerodynamics etc. Also, I disargee that planes are no longer beautiful. The F-22 has nice lines.

[@ronjon7942]

I agree with each. Whenever I see the Cutlass, I just have to stop what I’m doing and gape. But I had an art deco stylized poster of the Martin M-130 that made my heart ache, but I had to give it to a man with a business at the Oshkosh airport who was beginning some T-28 restoration projects - I wish I remembered his name, this was some 25 years ago - but he appreciated it even more so I had to give it to him. I often wonder what it is about aircraft that can sway a man - is it the technical aspects or the artistic that causes man to love machine.

[@Supatsu]

Another great vid! I do love me some interesting flying boat history. I know you get lots of requests.. I would KILL for your take on the interesting, colorful, checkered history on the Lockheed F-104 Starfighter (my favorite unforgiving little wasp of a plane!) I know it's a bit newer than most planes on this channel, but I'm hoping it's right in that sweet spot of cold war history that you'd be willing to cover?

3:00 Japanese written horizontally was generally written right to left before 1946. This is written with the classic old characters as used at that time in China as well, but the characters were simplified after the war. It says: 霞ヶ浦湖上F5號飛行艇. A model F5 flying boat ("hikoutei") on Kasumigaura Lake. (Since 1948 or so, 號 is now written 号.) 4:00 This was written left to right, which I honestly haven't seen in pre-war postcards, and I wonder if it was re-captioned as the printing looks modern. The photo is labelled Roorubahha ("Rolbach") R-1 flying boat at the bottom, and in white is labelled "Feb 1973 issue of Airplane Maniacs," I assume a magazine. Since it's not called a Hiro I assume it's an actual German-made plane. 5:04 This is credited Roorubahha/Hiro model R-3 flying boat. 8:02 一五式飛行艇改一: Type 15 flying boat (modified) 9:25 I can't guess where this might be from current maps, due to continued land reclamation all along the Japanese coast. If this shot is somewhere near the factory it might be the Muko river in Amagasaki, but who knows. 19:35 no idea why カモヰ (kamowi) is written on it but Google shows a model of a different flying boat with this registration. (Several other aircraft pictured have registration ヨ-60 so whatever this number is it's clearly reused.)
