Origins

The Gnat was the creation of W.E.W. "Teddy" Petter, a British aircraft designer formerly of Westland Aircraft

 OR.303 calling for a lightweight fighter, Petter believed that a small, simple fighter would offer the advantages of low purchase and operational costs. New lightweight turbojet engines that were being developed enabled the concept to take shape. Petter's first design resulted in the private venture Folland Midge

  which had a short lifespan, but served as a proof-of-concept design. It failed to interest the RAF as a combat aircraft, but they encouraged the development of a similar aircraft for training purposes.
The Midge first flew on 11 August 1954 but was destroyed in a crash on 20 September 1955. The Gnat, being developed in parallel with the Midge, was an improved version of the original fighter design, differentiated by larger air intakes for the Bristol Orpheus engine (the Midge had a Armstrong Siddeley Viper engine), a slightly larger wing, and provision for a 30 mm ADEN cannon

. Folland proposed the two-seat Fo. 144 Gnat Trainer, it had a new wing with additional fuel capacity, this allowed more room in the fuselage for additional equipment. A more powerful variant of the Orpheus engine was used, the front fuselage length was increased and had larger tail surfaces. The inboard ailerons of the fighter variant were changed to outbound ailerons and conventional flaps.

An initial contract for 14 pre-production Gnat trainers was issued in 7 January 1958. The prototype Gnat Trainer first flew on 31 August 1959 from Chilbolton airfield

All Gnats were grounded on 26 August 1958 for six months after the destruction of GN-102 due to a technical error, and the aircraft soon became the subject of severe criticism. Three other aircraft were also destroyed in other accidents. The Gnats were removed from active service in 1972 when the Häme Wing moved to Rovaniemi, and when the new Saab 35 Drakens were taken into use.

The first 13 aircraft for the Indian Air Force were assembled at Hamble, they were followed by partly completed aircraft and then sub-assemblies as Hindustan Aircraft slowly took over at first assembly then production of the aircraft.

The first flight of an Indian Air Force Gnat was in the United Kingdom on the 11 January 1958, it was delivered to India in the hold of a C-119 and accepted by the Air Force on the 30 January 1958. The first Gnat squadron was No. 23 (Cheetah) Squadron which converted from Vampire FB.52

By the end of 1971, the Gnat proved to be a frustrating opponent for the larger and heavier Sabre. The Gnat was referred to as "Sabre Slayers" by the Indian Air Force since all its combat "kills" during the two wars were against Sabres. The Canadair Sabre Mk 6 was widely regarded as the best dogfighter of its era. Tactics called for Gnats taking on the Sabres in the vertical arena, where the Sabres were at a disadvantage. Moreover, because the Gnat was lightweight and compact in shape, it was hard to see, especially at the low levels where most of the dogfights took place.
