Rolls-Royce RB.145
The Rolls-Royce RB.145 was a British jet engine designed in the early-1960s by Rolls-Royce for use as a lightweight VTOL lift and cruise engine. Developed from the Rolls-Royce RB108 the RB.145 featured more accessories and a higher thrust rating. Six engines developed by MAN Turbo were fitted to the first prototype of the EWR VJ 101 experimental German fighter aircraft, achieving supersonic flight by July 1964.
