The Pratt & Whitney J91 (company designation JT9) is a turbojet engine developed by Pratt & Whitney for the North American XB-70 Valkyrie Mach 3 bomber program. Although the General Electric YJ93 was selected for the XB-70, the J91 provided the basis for the later Pratt & Whitney J58 which would power the famous Lockheed SR-71 Blackbird.
