Folland Gnat F.1
Folland · UK · first flew 1955 · fighter
The Gnat F.1 is the original single-seat lightweight fighter, bought only by Finland and India (as the HAL-built Ajeet), featuring a delta-like highly swept wing and tiny dimensions that give it an almost model-aircraft appearance beside contemporary fighters.
Recognition (WEFT)
| W — Wings | Mid-mounted, delta |
|---|---|
| E — Engines | 1 × turbojet, fuselage-mounted |
| F — Fuselage | 9.04 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Single-seat cockpit with a small rounded canopy — noticeably narrower and shorter than the T.1 trainer's tandem hood
- Two 30 mm Aden cannon in the wing roots — gun ports visible in the leading edge roots; T.1 is unarmed
- Short, blunt nose without the extended avionics bay of the T.1; the F.1 nose profile is more compact and pointed
Against T.1: narrower single-seat cockpit, gun ports in wing roots, shorter nose, no tandem seating. The F.1 and T.1 share the general small-delta planform but differ substantially in nose length and cockpit width. Finland's silver-natural metal finish (vs RAF red/white T.1 trainer schemes) provides additional context in photographs.

History
Designed by W.E.W. 'Teddy' Petter as a minimal lightweight fighter, the Gnat F.1 first flew 18 July 1955. The RAF rejected it for fighters but adopted the T.1 trainer. Finland ordered 13 and India ordered 40, later building 175 as the HAL Ajeet with updates. The Ajeet saw action in the 1971 Indo-Pakistani War.
Variants
HAL Ajeet (Indian development with improved systems, overwing fuel tanks), Gnat T.1 (two-seat trainer, different design).
