Hi, looking for something else I found some references to the "Żywe torpedy" (Living Torpedoes, i.e. Human Torpedoes), an idea of Polish military to create a suicide unit in 1939 to attack the ships of the Kriegsmarine. The project is briefly mentioned in Covert Shore here, with a couple of...

Hullo all! Attached are a few images of a 1930s Goodyear-Zeppelin proposal for a large passenger airship based on the ZRS scout airship. All items are held in the collection of the University of Akron Archives, from which permission to post has been obtained. If there's any interest, I have a...

The Royal Navy's second 16" armed battleships history was a long and bumpy road of large number of designs and the inability on the Admiralty's side to actually start and continue it's work on them or choose a design to produce. First I present the 1938 designs: Design 14A-38 This is the first...

Japanese Wikipedia entry on Akizuki class DD stated that IJN started in 1936 to study dedicated AA vessels following the example of Dido class. They contemplated anything from a 1000 ton torpedo boat armed with a single 10 cm or 12.7 cm AA gun to a quite large cruiser equipped with 12 double...

Taiho was ordered as part of Maru 4 fleet expansion program. She was a compromised design, mating an armored flight deck to a Shokaku size hull, resulting in lower freeboard an reduced hangar capacity. The first, prewar, draft of the subsequent Maru 5 plan included 3 more armored carriers of a...

If you read French and you like weird tank projects, the latest issue of GBM Magazine (number 124) has a feature on the various French projects before WWII with multiple sets of tracks. Typically these would be two front tracks and two rear tracks, moving indepedently. The more spectacular are...

I'm putting this here under the thin justification that some of the cars were to be defensively armed, there were plans to transport small warships with it, and it could fill a logistics role similar to the Reichsautobahnen. However, I really just wanted a thread somewhere to discuss this. Some...
