"5th Submarine Division – Malta. It was announced on 31 July 1964, that British submarines were to leave Malta.[3] Captain C.H. Hammer was last Captain S.M. 5. HMS Ausonia, the division depot ship, set sail for the UK on 7 August 1964, and then paid off. Submarine depot ships at Malta were Forth (1948–1960), HMS Narvik (1960–1962), and then Ausonia from 1962 to 1964."
