Oruç Reis-class submarine

The Oruç Reis-class submarines were ordered by the Turkish Navy from the British company Vickers in 1939. They were similar to the British S-class submarines, but slightly smaller. They had the S-class machinery but only four bow torpedo tubes. The four boats were requisitioned by the Royal Navy on the outbreak of World War II and fought in the British fleet as the P611 class. Two submarines were delivered to the Turks in 1942 in order to bolster Turkish strength against the threat from Nazi Germany and the remaining surviving submarine was delivered to the Turkish Navy after the end of the war in 1945. P615 had been sunk in 1943. The three Turkish boats were scrapped in 1957.
