The Armstrong Siddeley Screamer was a 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.[1][2][3][4]

Work on the Screamer started in 1946, with the first static test at Armstrong Siddeley's rocket plant at Ansty in March 1954.[5] The programme was cancelled, as was the Avro 720, before flight testing. [6]

In 1951, a Gloster Meteor F.8 was experimentally fitted with a Screamer mounted below the fuselage. [7] [1]

The Screamer project was cancelled in March 1956, at a reported total cost of £ 650,000.[8]
