German submarine U-480

U-480 was an experimental Kriegsmarine Type VIIC U-boat of World War II. Considered by many to be the first stealth submarine, it was equipped with a special rubber coating (codenamed Alberich, after the German mythological character who had the ability to become invisible), that made it difficult to detect with British ASDIC (sonar).
