HMS Osprey, Portland

HMS Osprey was an anti-submarine training establishment located at the Isle of Portland, Dorset, England. It was active between 1924 and 1941, and again from 1946 to 1999. The helicopter station RNAS Portland formed part of the establishment from 1959 to 1999.

In 1948 Osprey took over (from HMS Boscawen) as parent ship of the naval base as a whole, with responsibility for pay, movement, administration and accounting. Subsequently all Portland-based naval personnel were borne on HMS Osprey, up until 1999 when Osprey was decommissioned.
