HMCS Okanagan (S74) was an Oberon-class submarine that served in the Canadian Forces (CF). The submarine, built at Chatham Dockyard in England, was laid down on 25 March 1965, and launched on 17 September 1966. She was commissioned on 22 June 1968. The submarine was named after the Okanagan First Nations people, and was assigned the pennant number 74.

Operational history

In July 1973, Okanagan collided with the Royal Fleet Auxiliary vessel Grey Rover while exercising in British waters. There were no injuries to the submarine's complement.

Decommissioning and fate

She was decommissioned from Maritime Command (MARCOM) on 14 September 1998. She had served her entire career with Maritime Forces Atlantic (MARLANT) in the North Atlantic.

In May 2005, the Halifax Chronicle-Herald announced that MARCOM was looking to sell Okanagan for scrap metal, along with three other Canadian Oberons laid up at CFB Halifax. MARCOM stated that the submarines were not in suitable condition to be used as museum ships and predicted that each submarine would sell for between C$50,000 and C$60,000. Okanagan was towed to a scrapyard in Port Maitland, Ontario in August 2011.
