Hi, I'm looking for any volume of the "Der Flug" magazine published in Vienna in 1920 by Österreichische Flugtechnische Verein (Austrian Aeronautical Association) - per WorldCat this magazine doesn't exist, but I have found an article from it (Das Problem der Weltraumfahrt from Dezember 1920...

This is the last of the post-Washington Treaty designed carriers covered in the 1st volume of USN 'Springstyle' design books. It's a small 10,000 ton Aircraft Carrier that looks like a 'regularized' version of the USS Langley (CV-1) conversion. Of note is that the armament is purely anti-surface...

As we all may know, the French were developing land-based heavy AA guns in the 1920s and 30s to counter the next-generation bombers of that time. They designed and tinkered a lot with 75 mm guns, then decided to up-gun it to 90 mm caliber. The 90 mm gun, or known as the Canon de 90 mm Modèle...

The history of the bullpup in France began long before the famous FAMAS which certainly marked its time but it was born under the constraint of the international conflicts. as assault rifle France had its misadventure during years from 1945 to 1970 with various programs and much expenditure...

Here I gathered all the various cruiser designs and projects proposed for the Imperial Japanese Navy Protected Cruisers: Not found any so far except the cancelled sister ships of the Unebi and Tone classes Light Cruisers: Design C-19 (1912) - A primary mine-layer cruiser design offered before...

Howdy folks! I recently came across these two designs/blueprints of the D-class panzerschiffe (more like battlecruisers at this point), which were originally named Ersatz Elsass and Ersatz Hessen that eventually became battlecruisers Scharnhorst and Gneisenau from my understanding of their...

In order to avoid clogging the IJN air service thread, I'd open an Army-specific thread for discussion about their alternatives in choice of flying hardware, logistics (as far as they can address it), production, etc. The Pacific war unfolds as it did hisorically, ie. the war with West starts as...

The M3 Halftrack and the Sdkfz 251 are the most well known ones, but did the other major powers have APCs? What about WW1?

I didn't see any topics featuring or referencing this interesting airship (including the compelling figures involved in its development and construction), but I came across a some newsreel footage of it worthy of posting and created this topic for reference and as a potentially clearinghouse for...

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 -...

With decades worth of hindsight, what might be the best steps for French AF and industry to make in the 1935 to 1940-41 time frame, in order to put up a better fight against Luftwaffe? Organizational changes, logistics, choice of what to make (whether the historical types, or whatever you think...

Time frame should cover gearing-up to the Pacific war and the war itself. What should've they specified differently for industry to make vs. what was made historically, in order to put up a better fight against the 'West', or mostly against the USN/USMC/USAAF? Not to make a host of designs that...

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...

In the magazine "Décollage" N°64 of 06.19.1947- p 12 .a reader Mr. Alphonse Martin informed the editorial staff of the magazine that he realized in 1939 the plans of a self-guided bomb. It is a gliding bomb launched by plane and equipped with an automatic piloting device which directs it towards...

French two prototypes buildt in 1919... is said to be one of the best looking aircraft of the WW1. The name " Sesquiplane" means 'one-and-a-half wings.'" Its sleek smooth streamlined wooden monocoque shell of tulipwood, was produced by winding thin spiral strips around a mould in a series of...

I'm on the scrounge. Does anyone have a copy , or just the key text, of specification R.2/33 that they would be willing to share? Failing that does anyone know whether the text of the specification has been included in any article or book, most likely one about the Sunderland. Thanks

Does anyone know Bohler 47mm L70? In WW2,Bohler 47mm L32 M1935 was famous,but according to some articles,47mm L32 couldn't be used well against tanks in the war,so Bohler designed L55,even...L70 I failed to find its data.
