Just a little added history note on the Seeteufel. Also known as "Elefant" or as Projekt Loedige it was the only advanced midget submarine project to attain actual construction and trials. The need for a tracked vehicle that could launch itself was apparent from the difficulties in getting other midget submarines in the water. Launching locations were usually limited to major ports. Dipl Ing Alois Loedige, head of the development division at the Kiel/Eckernförde torpedo testing establishment proposed this submarine as a solution. The first and only prototype to be built was completed in July 1944. It was fitted with an 80hp Opel truck engine although the original design called for a diesel. None of the latter were available. Trials were held in Eckernförde Bay. The Seeteufel proved capable of 8 knots submerged, 10 kts surfaced and had good maneuverability. On land it proved seriously underpowered and the tracks too small to adequitely support the weight. The decision was made to build a second prototype (pre-production model) using a 250 hp diesel and a 100 hp electric motor. This model was ordered from the Borgward Car factory at Bremen but was never built. The single existing prototype was blown up to prevent its capture at training camp 'Blaukoppel' outside Lübeck prior to the end of the war.
Yes, T.A. the Degtaryev is the correct answer: http://www.winterwar.com/Weapons/SuSmallArms/SUAutomatics.htm Over to you!
What was the make, model and, size of the largest gun fitted to any British Mk IV light tank (in any form)?
Well, that didn't work so well.....It was the 10.5cm (f) auf Geschultzwagen Pzkpfw VI(e), mounting the Canon de 105 court mle 1934s (in German service the 10.5cm leFH 324(f)). This was one of those many Bekker conversions that ended up in Normandy mostly with the 21st Panzer Division in 1944. Here's something a bit different: What is the highest point reached by a tank in WW II (under its own power)?
The world's highest tank was an M3 Grant belonging to the 3rd Carabiniers, C squadron that assended to the top of Kennedy Peak (8871 ft / 2725 meters) in the Chin Hills of Burma in November 1944. I open the floor to all for a new question!
OK, I´ll take it then! BTW, that was a great question T.A.! New question: Where and when in the Pacific did the US army first use the manpack Flamethrower in WW2?
The US army first used the manpack flamethrower in Guadalcanal in January 1943 by the 2nd Marine and 25th Infantry Divisions.
