Following my visit to the Technik Museum in Sinsheim last month, where the Type 206 U-17 is on display (https://forum.rc-sub.com/forum/photo...any#post193798) I had the opportunity to go the museum's other site at Speyer a few days ago, below are a few photos of the submarine's on display.
The Type 205 submarine U-9 has been on display here since the mid 1990's. In the late 1950's West Germany was authorised to build small submarines (initially under 350 tonnes) primarily to support NATO defence of the Baltic sea. The first class to be built was the Type 201 which incorporated non magnetic steel to reduce the risk from magnetic mines, followed shortly afterwards by a lengthened version with an improved sail arrangement. However, the non magnetic steel selected proved problematic as was subsequently found to prone to corrosion and fine cracks limiting the operational life of the Type 201 and 205 submarines built with it. As a result the first batch of Type 205's had a short operational life as training submarines, while the first two Type 201's (U-1 and U-2) were essentially scrapped and rebuilt as Type 205's. A second batch of four Type 205's were built U9 - U12 test alternative non magnetic steels, as well as other improvements which were primarily used as test and trials boats. The later Type 206 enter service in the early 1970's and was based on the Type 205 design with several improvements including the final selection of non magnetic steel. Also the export Type 207 (Kobben class) were based on the 205 design.
U-9 is an example of the second batch (known as the Type 205 mod) of Type 205's incorporating an alternative steel type. It has the original Type 205/201 rudder arrangement with twin rudders outboard of the propeller which unfortunately, this gave the submarine a very large turning radius. To improve the turn radius the final Type 205's (U-11 and U-12) had a different arrangement with the rudder behind the propeller and arrangement which was adopted in the Type 206.
As expected the internal arrangement of U-9 is similar to that of U-17, although as it is slightly shorter the control room is somewhat smaller and more cramped.
Also on display in one of the main halls are WWII German Biber, Seehund and Marder midget submarines.
Both museum sites are well worth a visit, with broad range of aircraft, cars, motorcycles boats, spaceflight articles, trains and other items on display.
