Canadair Sabre Mk 4
Canadair · Canada · first flew 1952 · fighter
The Canadair Sabre Mk 4 was the primary variant delivered to RAF Germany as an interim fighter, powered by the American J47 engine rather than the Canadian Orenda that distinguished the Mk 6. It is externally very similar to the F-86E.
Recognition (WEFT)
| W — Wings | Mid-mounted, swept |
|---|---|
| E — Engines | 1 × turbojet, fuselage-mounted |
| F — Fuselage | 11.43 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- General Electric J47 engine as in US Sabres — no intake modification visible versus Mk 6's Orenda
- Leading-edge slats retained — slat gaps visible on upper wing surface unlike the 6-3 wing F-86F
- RAF roundels and camouflage on the majority of surviving aircraft — the Mk 4 was primarily a NATO/RAF type
The Mk 4 is essentially indistinguishable from the F-86E externally; the J47 engine means the intake is identical. Leading-edge slats (visible as a seam on the upper wing) distinguish the Mk 4 from the F-86F's 6-3 wing. RAF markings are the strongest identifier for a museum context.

History
430 Mk 4s built, primarily for the RAF under a Mutual Defence Assistance Program arrangement. RAF Germany squadrons operated the Mk 4 from 1952, providing the 2nd Tactical Air Force with a modern swept-wing fighter while Hunters were developed. Replaced by the Hunter F.4 from 1956.
Variants
The Mk 2 was an earlier J47-powered variant. The Mk 5 introduced the Orenda engine. The Mk 6 is the definitive Orenda-powered variant. Many Mk 4s were passed to Yugoslavia and Italy after RAF service.
Where you'll see it
RAF Germany 1952-1956; Yugoslavia (as Mk 4 transfers) until the 1970s. Static examples rare; most Canadair Sabres preserved are Mk 6 standard.
