Rolls-Royce Marine Olympus

The Rolls-Royce Marine Olympus is a marine gas turbine based on the Rolls-Royce Olympus aircraft turbojet. The first was built for the German Navy, with BSEL contracted to provide the gas generator and Brown Boveri a two-stage long-life power turbine, but construction of the ship intended for it was abandoned. Test running of the next marine Olympus began in 1966, with a single-stage power turbine running at 5,600 rpm. The Finnish Navy corvette Turunmaa began sea trials in early 1968 and was the first Olympus-powered warship to enter service, some six months before HMS Exmouth, the first British ship refitted to trial the system. The TM1 and TM2 variants were rated at 23,200 shp nominal and the TM3 at 28,000 shp, and the TM3 powered Royal Navy Invincible-class carriers and Type 42 destroyers among many other ships. Maximum power is quoted as 28,500 shp.
