Unterseeboot 20, or more commonly U-20 was a German Type IIB U-boat of the Kriegsmarine. Her keel was laid down August 1, 1935 by Germaniawerft of Kiel. She was commissioned on February 1, 1936. During the World War II, she conducted operations against enemy shipping.

U-20 went on 17 patrols, sinking 16 ships totalling 39,637 tons and damaging one more of 1,846 tons.

Fate

On June 26, 1943, U-20 was attacked with depth charges in the Black Sea by a convoy escort. The damage was such that she had to return to base. She was scuttled on September 10, 1944 in the Black Sea off the coast of Turkey.

On February 3, 2008, The Telegraph reported that U-20 had been discovered by Selçuk Kolay, a Turkish marine engineer, in 80 feet of water off the coast of the Turkish city of Zonguldak.
