The Hawker Siddeley APD.1019 was a series of mid 1960's studies into designs for a research aircraft capable of Mach 5. Several different versions were produced, ranging from 21-58 tonnes. Configurations ranged from relatively conventional canard deltas to advanced lifting body flying wedges. Propulsion options included hydrogen fuelled scramjets and turborockets (an engine capable of operating as a turbojet or a rocket).
