The Rolls-Royce RB.203 Trent was a British medium-bypass turbofan engine of around 10,000lb thrust designed for production in the late 1960s, bearing no relation to the earlier Rolls-Royce RB.50 Trent turboprop or the later high bypass Rolls-Royce Trent turbofan.[2]
The RB.203 was a private venture engine built on the core of the Rolls-Royce Turbomeca Adour turbofan used in the SEPECAT Jaguar and the later Hawker Siddeley Hawk.[3]
The RB.203, the first three-spool engine, was intended as a civilian replacement for the earlier Rolls-Royce Spey.[4]
