Avro Vulcan B.1
Avro · United Kingdom · first flew 1952 · bomber
The Vulcan B.1 was the initial production variant with a pure straight-edged delta wing, serving as Britain's nuclear deterrent before being superseded by the aerodynamically superior B.2.
Recognition (WEFT)
| W — Wings | Mid-mounted, delta |
|---|---|
| E — Engines | 4 × turbojet, embedded-mounted |
| F — Fuselage | 29.6 m fuselage |
| T — Tail | No tailplane |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Straight delta leading edge with no kink — the B.1's wing sweeps at a constant angle from root to tip, unlike the B.2's kinked leading edge
- Smaller wing area overall; the leading edge appears as a clean uninterrupted diagonal line when viewed from below
- Narrow engine intakes with a simple rectangular lip — the B.2's intakes were enlarged with a more complex shape
Against the B.2, the B.1's wing leading edge is a single uninterrupted sweep with no kink at mid-span; the B.2's leading edge has a visible double-curve giving it a larger, broader appearance especially from the front quarter.
Specifications
- The Avro Vulcan B.1 has a length of 29.6 m (97 ft).
- It has a wingspan of 29.5 m (97 ft).
- Its maximum speed is 1038 km/h (645 mph).
- Typical crew: 5.

History
The B.1 entered service with No. 83 Squadron in 1956, giving the RAF its first jet-powered delta bomber. Performance was adequate but the type showed limitations at very high altitude against improving Soviet defences, and the B.1 was progressively modified and replaced by the kinked-wing B.2 from 1960 onward.
Variants
The B.1A introduced an electronic countermeasures suite in a revised tail cone; most B.1s were upgraded to this standard before retirement.
Where you'll see it
No complete B.1 survives; B.1 airframes were scrapped or used for ground instruction when replaced by B.2s. The surviving airworthy Vulcan (XH558) and all museum examples are B.2 airframes.
