However, the Type XXI would last through the Cold War. Some were used for target practice. Others were captured and commissioned into the Soviet and French navies. The only surviving vessel of its class today is the Wilhelm Bauer, which the modern Germany navy converted into a research vessel. It’s now a museum ship in Bremerhaven. But mainly, the Type XXI provides several lessons in how technology—while important—doesn’t alone win wars. It’s also a lesson in how the fanatical pursuit of advanced weapons can make winning wars a lot harder.
On May 4, 1945 one of the most advanced submarines in the world crept up to a British Royal Navy cruiser. U-2511 was one of Germany’s new Type XXI-class “wonder” submarines, and she was hunting for Allied ships.
She also represented one of the Third Reich’s biggest failures.
More than 250 feet long and displacing 1,620 tons, the Type XXI packed six hydraulically-reloaded torpedo tubes capable of firing more than 23 stored torpedoes. This arsenal could turn a convoy into sinking, burning wreckage.
