McDonnell Aircraft
McDonnell Aircraft Corporation submitted a design which included a cropped-delta-wing decoy constructed largely of fiberglass and carried internally within a B-52. The following month on February 1, 1956, the McDonnell Aircraft Corporation was awarded a contract to develop Weapon System 122A which included the GAM-72 "Green Quail" missile. In June 1956 General Electric was selected as the engine contractor for the GAM-72. Guidance components were built by Summers Gyroscope and the countermeasures equipment by Ramo-Wooldridge Corporation.
