HM Submarine M, surfacing along side a ship in about 1930.

M2 was one of three M Class submarines. In 1927 it was converted to carry a seaplane in a hangar and in 1928 a catapult was fitted to assist in launching the aircraft. The aircraft carried was a Parnall Peto two-seat reconnaissance biplane. Both the submarine and seaplane were lost on 26 January 1932 when the submarine sank in an accident.
