Dates: 1968 - 1998

HMCS Okanagan (S74) was an Oberon-class submarine of the Royal Canadian Navy, later Canadian Forces. She was built at Chatham Dockyard - the last warship to be built there. She was commissioned in June 1968. Complement: 69.

Upon completion, Okanagan worked to Halifax before commissioning.

Several years’ normal service followed, but in July 1973 Okanagan collided with the Royal Fleet Auxiliary vessel Grey Rover while exercising in British waters. Fortunately there were no injuries to the submarine’s crew.

Okanagan participated in the filming of the Japanese disaster film Fukkatsu no hi, released in 1980.

The Canadian Oberon-class submarines were replaced by the ex-RN Upholder clas boats, refitted and re-commissioned as the Victoria class.
