Currently berthed at the NATO jetty in Loch Striven is one of the Royal Fleet Auxiliary's oldest vessels, the fleet tanker BLACK ROVER. Built in 1973 by Swan Hunter Shipbuilders at Wallsend on the River Tyne, she was one of five similar ships, of which just two now remain in service. Due to be decommissioned in 2010, BLACK ROVER entered service with the RFA in 1974. She is 140.6 metres in length, and her deadweight is 6,992 tonnes. Main propulsion is from two Crossley-Pielstick engines driving a single screw. She recently underwent a three-month long refit at Falmouth.
