I just dig the shit out of stuff like this. If you haven't read the book "Shadow Divers" I highly recommend it.

They should make Shadow Divers into a movie... AMAZING real life story. Every diver should read it.

Re: Nazi Germany's Most High-Tech Submarine Has Been Found

Michael C. Barnett did a nice write-up about the U-2513, a Type XXI which was handed over to the USN after WWII and scuttled in 214 fsw off the Dry Tortugas after several years of testing: http://www.advanceddivermagazine.com...513/u2513.html


Very impressive boats for the mid-1940s; most WWII subs were built to run on the surface most of the time and crawl along underwater at a max of about 8-9 knots when attacking ships. The Type XXI could run submerged on its batteries at 5 knots for 2-3 days or manage a 90-minute speed run at 17 knots. Given that the hydrophones on a surface ship would be useless above a speed of 10-11 knots, they would have been able to evade a counterattack by sub-hunters. The Germans developed a very efficient assembly line system to mass-produce them; however as a lot of the contractors weren't experienced in building subs and the Allies were bombing the crap out of German territory it was too late. They built 118 of those boats, but only four actually entered service by war's end and just two of those made an operational patrol. They never even fired a shot in combat. They were prize acquisitions after the war for the Allied navies.

A couple Type XXIs that were scuttled or sunk are diveable, although the ones I'm aware of are all at 200 fsw or deeper. The West German Navy salvaged one scuttled example during the Cold War and refitted it as a test ship; it was retired in the 1980s and returned to its WWII configuration as a museum ship: https://en.wikipedia.org/wiki/German..._Wilhelm_Bauer
