structure with lateral engine inlets on each side of the nose. Wind tunnel tests began in 1953 as did testing of scale models at speeds up to . A full scale glider was built and made its first flight on 1 October 1954. Most unusually the pilot lay prone and looked out through the clear nose. Flight performance was deemed excellent and manufacture of a prototype powered by a Rolls-Royce Derwent V began in 1955. This engine was selected as it was readily available, but lacked the thrust desired for the fighter. The glider was modified with a normal cockpit in 1956. Shortly afterwards the program was split with the current aircraft becoming a subsonic trainer and a new, more powerful fighter, designated as the I.Ae. 48, with two podded engines under the wings and intended to reach Mach 2.2 (2,700 km/h). However, both projects were cancelled in 1960 as an economy measure, only a year before the I.Ae. 37 was to fly.
