Vulcan

The Avro Vulcan, later known as the Hawker Siddeley Vulcan, was a jet-powered, tailless, delta-wing strategic bomber operated by the Royal Air Force (RAF) from 1956 until 1984. Designed by A.V. Roe and Company to satisfy Specification B.35/46, the project used several reduced-scale Avro 707 aircraft to test delta-wing principles. The first prototype, VX770, flew on 30 August 1952. Total production reached 134 aircraft, consisting of 45 B.1 and 89 B.2 models.

Design

The airframe was constructed primarily of light alloy and featured a five-man crew in a pressurized cabin. The pilot and co-pilot were equipped with Martin-Baker ejection seats, while the three rear crew members—navigator radar, navigator plotter, and air electronics officer (AEO)—exited via the entrance door. Power was provided by four Rolls-Royce Olympus turbojet engines buried in the wing roots. The B.2 variant introduced the larger Phase 2C wing and transitioned from the B.1’s 112V DC electrical system to a 200V AC system. Avionics included H2S Mk9 radar, a navigation bombing computer, and electronic countermeasures (ECM) systems housed in an extended tail cone. Later B.2 modifications added terrain-following radar and a heading reference system based on the Blue Steel missile’s inertial platform.

Armament

Armament was carried in a single internal bomb bay. Conventional capacity was 21 1,000 lb bombs. Nuclear payloads included Blue Danube, Violet Club, Yellow Sun Mk.1 and Mk.2, Red Beard, and WE.177B gravity bombs. The B.2 was also modified to carry the Blue Steel stand-off missile. During the 1982 Falklands War, aircraft were fitted with underwing pylons to carry AGM-45 Shrike anti-radar missiles and ECM pods.

Operational History

The Vulcan served as the backbone of the United Kingdom's airborne nuclear deterrent. From 1962, aircraft were held on Quick Reaction Alert (QRA), prepared for takeoff within 15 minutes. While originally designed for high-altitude flight, the fleet transitioned to low-level penetration tactics in the mid-1960s. During Operation Black Buck in 1982, Vulcans flew 3,889-mile missions from Ascension Island to Port Stanley. The type also performed maritime radar reconnaissance and aerial refueling roles before its final withdrawal from service.

Variants

• B.1: The initial production variant equipped with Olympus 101, 102, or 104 engines and a pure delta wing.
• B.1A: B.1 aircraft retrofitted with B.2-style ECM equipment in an enlarged tail cone and in-flight refueling probes.
• B.2: An improved version featuring a larger, thinner Phase 2C wing, uprated Olympus 200 or 300-series engines, and an AC electrical system.
• B.2 (MRR): Nine aircraft modified for maritime radar reconnaissance, featuring LORAN C navigation and the removal of terrain-following radar.
• K.2: Six B.2 airframes converted into single-point tankers with a hose drum unit in the tail and three additional bomb-bay fuel tanks.
