Prior to August 1945, the Vultee Division of Consolidated-Vultee looked at the possibility of a swept-wing aircraft powered by a ducted rocket. Years earlier, the company had performed designs which involved liquid-cooled radiator engines.  With this design, fuel would be added to the heat produced by small rocket engines in the duct, creating a "pseudo-[[ramjet]]".<ref name="J&L p. 122">Jenkins and Landis 2008, p. 122.</ref>

In August 1945, the [[United States Army Air Forces]] (USAAF), soon to be renamed the [[United States Air Force]], issued a proposal for a supersonic interceptor capable of {{convert|700|mi/h|km/h|abbr=on}} speeds and reaching an altitude of {{convert|50000|ft|m}} in four minutes.{{Citation needed|date=July 2011}} Several companies responded, among which was Consolidated-Vultee, which submitted its design on 13 October 1945.<ref name="J&L p. 122"/> This design featured swept wings and [[V-tail]]s, as well as a powerful propulsion system. Besides the ducted rocket, four {{Convert|1,200|lbf|kN}} rockets were positioned at the exhaust nozzle, along with the {{Convert|1,560|lbf|kN}} 19XB turbojet produced by Westinghouse.<ref name="J&L p. 122"/>

A proposal by [[Consolidated Vultee]] (later Convair) was accepted in May 1946, with a proposal for a ramjet-powered aircraft, with a 45° [[swept wing]] under USAAF [[Air Materiel Command]] Secret Project MX-813. However, [[wind tunnel]] testing demonstrated a number of problems with this design.<ref name=baugher>Baughe, r, Joe.
