RFA Black Ranger (A163)

RFA Black Ranger (A163) was a British diesel-powered fleet support tanker of the Royal Fleet Auxiliary, built by Harland & Wolff. It served with the Arctic Convoys, and was involved in a collision with the submarine HMS Thule (P325) in November 1960. Its role was to refuel the RAF flying boats, and carried 2,600 tons of fuel oil, 550 tons of diesel, and 90 tons of petroleum. The Greeks purchased it and renamed it Petrola XIV in 1973.
