Which Rolls-Royce engine powered the Concorde supersonic airliner?

The Rolls-Royce/Snecma Olympus 593 powered the Concorde supersonic airliner.

The Olympus 593 was a turbojet developed jointly by Britain’s Rolls-Royce and France’s Snecma for Concorde. Concorde required engines capable of sustaining supersonic cruise, and its four Olympus engines were fitted with afterburners to provide additional thrust during takeoff and acceleration.

Concorde’s engine arrangement is sometimes confused with Rolls-Royce turbofans such as the RB211 and Trent families. Those engines powered subsonic commercial aircraft and were designed around different efficiency requirements. The Olympus 593 was a turbojet, not a high-bypass turbofan.

Concorde entered scheduled passenger service in 1976 and remained one of the best-known civil supersonic aircraft. Its retirement in 2003 ended regular supersonic passenger flights, but the Olympus 593 remains closely associated with the aircraft’s distinctive performance.
