The Armstrong Siddeley Stentor, latterly Bristol Siddeley BSSt.1 Stentor, was a two-chamber HTP rocket engine used to power the Blue Steel stand-off missile carried by Britain's V bomber force.[1][2] The high thrust chamber was used for the first 29 seconds, after which it was shut down and a smaller cruise chamber was used for the rest of the powered flight.[3][4][5]

It was fuelled by hydrogen peroxide with kerosene.[1]
The engine incorporated an integral tubular mounting frame which was attached by six lugs to the rear bulkhead of the missile airframe, the complete engine being enclosed in a tube-shaped fairing with the nozzles at the rear.
