The Armstrong Siddeley Screamer was a British rocket engine intended to power the Avro 720 manned interceptor aircraft (Avro's competitor to the Saunders-Roe SR.53 for a rocket-powered interceptor). Thrust was variable, up to a maximum of 8,000 lbf (36 kN).[1][2][3]

Design and development
Work on the Screamer started in 1946, with the first static test at Armstrong Siddeley's rocket plant at Ansty in March 1954.[4] The programme was cancelled, as was the Avro 720, before flight testing.[5]
In 1951, a Gloster Meteor F.8 was experimentally fitted with a Screamer mounted below the fuselage.[1][6]
The Screamer project was cancelled in March 1956, at a reported total cost of £650,000.[7]
