Biber Midget Submarine

The «Biber» was the most well-known «pocket» submarine used by the Kriegsmarine during the latter part of World War II. The development of the Biber was extremely rapid. Design began in February 1944, and the first units were launched just 6 months later. Measuring just 9 meters long, it had a range of 240 km. It could reach a maximum speed of 6.5 knots surfaced and 5.3 knots submerged. The Biber could be armed with two 530 mm torpedoes, mounted externally to the submarine, or with two mines.
