[4] Propulsion machinery consisted of 2 Admiralty Standard Range 16 VMS diesel generators, and two 3,000 shaft horsepower (2,200 kW) electric motors, each driving a 7-foot-diameter (2.1 m), 3-bladed propeller at up to 400 rpm.

[4] In September 1967 Olympus was among the vessels sent in search of a downed French Navy Breguet Atlantic which had been operating out of RAF Kinloss.

Olympus completed a two year refit at Devonport in July 1982, being fitted with a new Aluminum Fin and a 5-man swim-out chamber to aid submerged exit and entry of special forces swimmers.

After rendezvousing with the submarine a few miles out of Plymouth Sound, presenter Anneka Rice watched on from the show's helicopter as Olympus surfaced, before landing on her hull and receiving the episode's second clue from the vessel's captain, Lt. Cmdr.

[10] Retired from the Royal Navy, Olympus was sold to the Canadian Forces in 1989 and was stationed as a non-operational training boat in Halifax, Nova Scotia.

[14] In July 2011, Olympus started making her journey from Halifax to a scrapyard (International Marine Salvage) in Port Maitland, Ontario.
