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

Spot it by:

Look for a single-engine jet with swept wings and tail, a deep oval fuselage and a nose intake. The guns sit in the nose above the intake and in the wing roots.

History

The design began as a simple upgrade of the Thunderjet to compete with the F-86 Sabre, using a swept wing and tail. Prototypes flew from June 1950, but production was repeatedly delayed and the engine was changed to the more powerful Wright J65, a US-built Armstrong Siddeley Sapphire. The larger engine required a stretched, oval fuselage and a modified intake, making the aircraft effectively a new design.

Variants

The RF-84F Thunderflash was the photo-reconnaissance version. The first 275 aircraft had a conventional stabiliser-elevator tailplane and suffered pitch-up and poor turning at combat speeds, which led to a change of tailplane design.

Where you'll see it

The F-84F entered service in November 1954, by which time the Sabre had been much improved, and the Thunderstreak was used as a fighter-bomber. It began moving to secondary roles early and left US Air National Guard service in 1972, while Greece retired its aircraft in 1991.
