McDonnell Douglas F-4 Phantom II FG.1

McDonnell Douglas · USA · first flew 1966 · fighter

The FG.1 was the Royal Navy's carrier-borne Phantom, re-engined with Rolls-Royce Speys in a substantially modified airframe. The wider intakes are the single most visible identification feature setting all British Phantoms apart from every other Phantom variant.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

The wide, square-lipped intakes are the instant tell for any British Phantom — they are broader than any US-engined mark by a visible margin. Compare with the oval, narrower intakes of J79-powered aircraft. Arrestor hook and absence of chin cannon confirm FG.1 over FGR.2.

History

Ordered to replace the de Havilland Sea Vixen on carriers; the Spey reengining promised better low-altitude performance and single-engine safety. About 52 FG.1s were built. The premature scrapping of HMS Ark Royal in 1978 made the aircraft redundant for carrier work; most passed to the RAF.

Variants

The FGR.2 is the RAF ground-attack equivalent. When transferred to the RAF the FG.1s retained their designation but flew in the air defence role.

Where you'll see it
