This turbojet aero engine, the Olympus 593, was made in 1969 by the Bristol Siddeley Engine Division of Rolls-Royce Ltd. It was used in both the British and French prototypes of Concorde between 1969 and 1973.

The engine is an axial flow gas turbine: the air drawn through the compression stages into the combustion chamber flows along the engine's longitudinal axis. (Axial flow engines are generally more complex and have more moving parts but a greater power output.) The engine's nameplate is marked 'BRISTOL OLYMPUS 593 ENGINE-MOTEUR, MARK 593B, SERIAL 59367, MIN'.

The Olympus engine was originally designed for the subsonic Avro Vulcan as the Olympus 101 in 1956 but was chosen for extensive development for a low altitude supersonic role for the British Aircraft Corporation TSR.2. The modified powerplant proved troublesome and not all the faults were cured before cancellation of TSR.2 in 1965. Further development resulted in the Olympus 593, the world's first fully certified engine for commercial supersonic operation.
