Everyone knows about the Dormier P.85 aircraft project, a Do17Z with, among other differences, floats and straight wings. It wasn`t included in the attached table, taken from a BA/MA file on the contest for a seaplane bomber, known as "Kampfflugzeug See" or as See-Stuka, as may see. There were...

Those who tought, like me, that all the German engineering expertise on hardware airships ended with the Hindenburg, are wrong. The BA/MA in Freiburg has a file (included in RM 7/2382), dated 12.2.1938,and stemming from the Kriegsmarine, refering to a proposal, serious enough to the point of...

Hi! Competitor Focke-Wulf FW.57. http://www.airwar.ru/enc/fww2/fw57.html

Hi everyone, Just like my previous threads in the same section, talking about French antitank weapon projects in development in the interwar period or up to 1940 that didn't get to enter service, based on my archive findings. I'm gonna start with the ones that caught me completetely off-guard...

Hi Guys I came across information on the internet that the Japanese used: Messerschmitt Bf.109G Dornier Do. 215 Focke-Wulf Ta.154 Savoia-Marchetti SM.79 Reggiane Re.2000 Japanese homegrown Mistel project similar to the Germans (N1K fighter on a modified J5M bomb) Could this be a case of...

Does anyone have: - general plans and armor scheme of the Eendrachts. For the armor, the correct figures seems to be 100mm belt of unknown height and length closed by 60mm traverses at the end barbettes, with 75mm armor extending beyond the citadel on the sides for an unknown distance, topped by...

A one-off design by Ernst Jachtmann who had famously set endurance records in gliders including a 41 hour flight in 1937, he can be seen in the cockpit in the media below.

The Invention Of The Jet Engine: Hans Von Ohain, One Of The Fathers Of the Turbojet

The Navweps site on these two guns has some passing mentions that lead me to other questions: -135 mm/45 (5.3") Models 1937 and 1938: There is this statement: "A twin AA version for the Etna class cruisers and for the rebuild of the damaged battleship Conte Di Cavour were only in the...

Hello! The book French Battleships 1922-56 mentions that for the Alsace-class battleship designs, studies for 400, 406, and 420mm guns were ordered. Additionally, a 406mm naval gun was created by the Schneider company for the Soviet Union, and a 431mm naval gun was created: the elusive Canon de...

https://naval-encyclopedia.com/ww2/italy/aircraft-carrier-aquila.php?amp=1 According to the site above, there are several aircraft carrier plans planned by Regia Marina's Lieutenant General Bonfiglietti, does anyone know more about this?

In 1939, France's Edgar Brandt & Company offered the French Army a series of three HEAT grenades...a 50mm-diameter design to be fired from standard infantry rifles, a 60mm design to be fired from the rifle-caliber medium machine gun in single shot mode, and an 80mm design to be fired from the...

Starting point Juan de la Cierva had already decided to continue his work motorizing the gyroplane's rotor. He misses his flight at Croydon which crashes in December 1936 because his car has a flat tire. He travels on the next flight, meets with Focke, and together they design and develop two...

Just realized that i have never seen any drawings of interim projects that eventually led to the G-50/F6F. There was an G-33 based on the XF4F-2 but with R-2600 engine, and as i understand initial G-50 projects had still much in common with the F4F (mid-wing, fuselage landing gear etc.). Are...

The C-35 and the C-36 are well known, actually built, aircraft of "Eidgenössische Konstruktionswerkstätte" in Thun. The planned C-37 is rather less known. Last year I had the chance to re-work an 1978-article of "Cockpit" and I was lucky to get to see a painting of Roland Eichenberger -...
