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...

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 -...

I've seen a few references to a Supermarine early World War II project called the Type 312. From what I've read, it was a derivative of the Spitfire but with standard cannon armament and a ventral radiator instead of the Spitfire's underwing radiators. Does any photos or plans or other details...

Last year the Vickers Machine Gun Collection and Research uploaded several Summary Reports for the President of the Ordnance Board, the vast majority of them freely available. Although lacking detail (by their nature as summary reports) they cover the Aircraft Ordnance Fuses, Projectiles (Land...

This is an alternative history of Goddard's historical liquid rocket launch of 1926 and the succeeding development of a fictional experimental rocket airplane based on Goddard's designs. The advent of the design and its governmental support ultimately leads to a change in the course of the US...

The Ohama and her sister ship Okashi were laid down as target ships, successors to the Hakachi. Ohama was completed as an escort vessel, and Ohashi collided with Yamashio Maru and sunk before completion, but would have been given the same treatment. I can't find any illustrations of their...

Video might be of interest. Can't speak to its accuracy, but at least it doesn't seem too insane. View: https://www.youtube.com/watch?v=kfio0VHXUmw

Hai Except some drawings concerning the P-33 projects, I did not find any information concerning other Brewster projects. The only which I earlier mentioned was the two-seat fighter, further no details etc. Is there any material/information concerning this two-seat fighter and other not...

Or, in other words, lets give to the FAA some attractive hardware that gets the job done and then some. Whether something later to be made earlier, or something that never flew, or a substantial mod to an existing design. Limitations of availability of engines, armament and electronics remain -...

This thread is organized by ship type when information is available, and includes general plans when unavailable. It starts with Destroyer plans, moves to Battleship plans, then to Cruiser plans, and finally to Aircraft Carrier plans, followed by lists of various war demands and fleet building...

Since the end of the First World War, bold attempts were made in the Soviet Union in the field of rockets and various types of weapons, although timid, but existing and somewhat significant for the hard period that the Union was going through at that time, sometimes typically handcrafted and...
