Two prototypes were built, the first being flown on May 25, 1950 and the second following in August 1951. Planned armament comprised three 0.787 in (20 mm) Hispano-Suiza cannon and provision was made for underwing ordnance loads such as two 1,102 lb (500 kg) bombs, but the second prototype had provision for two 0.787 in (20 mm) cannon, two 0.303 in (7.7 mm) machine guns and 36 RAC 50 rockets internally, plus provision for 16 T10 or 80 RAC 50 rockets on wing racks. A third prototype which was to have received an 8,818 lb (4,000 kg) SNECMA Atar 101F turbojet was abandoned."
