Design and development

The BS.605 design was based on the smaller of two combustion chambers of the earlier Armstrong Siddeley Stentor. A pair of retractable BS.605 engines were fitted to Buccaneer S.50 strike aircraft of the South African Air Force for hot and high operations. The BS.605 was also considered for the Bluebird CMN-8, a design for a supersonic land speed record car, to be driven by Donald Campbell.^[1]
