The Bréguet 1100 was a twin-engine French light fighter also suitable for ground-attack and built for the French armed forces. First flown in 1957, only one was completed as budget cuts led to cancellation of the programme.

Design and development

The single-engine Bréguet 1001 Taon was designed and built for a NATO fast ground-attack fighter competition. The Bréguet 1100 was a development designed instead to a French Ministère de l'Air (English: Air Ministry) specification, which called for two engines and a pressurised cockpit in an aircraft performing a similar role.^[1] The 1100 flew before the Taon, as the latter was delayed to incorporate the new area rule late in its construction.^[2]

The Bréguet 1100 was built entirely from bonded alloy and included many honeycomb structures.^[1] Its swept wing was about 15% greater in span and 35% greater in area than that of the Taon, though it was intended that production Taons would share the 1100's wing.^[2] The 1100 had broad chord, short-span ailerons and narrow, long-span flaps with spoilers in front of them.^[1] The two types had similar side air intakes but the 1100's twin mid-fuselage engines and jet pipes meant that the fuselage was broader and lacked any area rule waisting, as well as being rather longer. They also shared similar swept, straight-edged tail surfaces, cockpits in the nose with narrow fairings running over the length of the upper fuselage and tricycle landing gear.^[2]

Sixteen different armament packages were available, including four 12.7 mm (0.5 in) Browning machine guns, two 30 mm (1.2 in) DEFA cannon, 35 Matra unguided rockets or a pack of fifteen 68 mm (2.7 in) SNEB 22 rockets.^[1]^[2]

The 1100 first flew on 31 March 1957, exceeding Mach 1. This first prototype was the only one to fly as the second was abandoned when 80% complete and an ordered third prototype, a navalized version designated 1100M, was not begun.^[2] Before mid-1959 the Bréguet 1100 programme had been cancelled due to government spending cuts.^[3]
