The Avro Vulcan (later Hawker Siddeley Vulcan from July 1963) is a jet-powered tailless delta wing high-altitude strategic bomber, which was operated by the Royal Air Force (RAF) from 1956 until 1984. Aircraft manufacturer A.V. Roe and Company (Avro) designed the Vulcan in response to Specification B.35/46. Of the three V bombers produced, the Vulcan was considered the most technically advanced and hence the riskiest option. Several scale aircraft, designated Avro 707, were produced to test and refine the delta wing design principles.

The Vulcan B.1 was first delivered to the RAF in 1956; deliveries of the improved Vulcan B.2 started in 1960. The B.2 featured more powerful engines, a larger wing, an improved electrical system and electronic countermeasures (ECM); many were modified to accept the Blue Steel missile. As a part of the V-force, the Vulcan was the backbone of the United Kingdom's airborne nuclear deterrent during much of the Cold War. Although the Vulcan was typically armed with nuclear weapons, it was capable of conventional bombing missions, a capability which was used in Operation Black Buck during the Falklands War between the United Kingdom and Argentina in 1982.

The Vulcan had no defensive weaponry, initially relying upon high-speed high-altitude flight to evade interception. Electronic countermeasures were employed by the B.1 (designated B.1A) and B.2 from circa 1960. A change to low-level tactics was made in the mid-1960s. In the mid-1970s nine Vulcans were adapted for maritime radar reconnaissance operations, redesignated as B.2 (MRR). In the final years of service six Vulcans were converted to the K.2 tanker configuration for aerial refueling.

After retirement by the RAF one example, B.2 XH558, named "The Spirit of Great Britain" was restored for use in display flights and air shows, whilst two other B.2s, XL426 and XM655, have been kept in taxiable condition for ground runs and demonstrations at London Southend Airport and Wellesbourne Mountford Airfieldrespectively. B.2 XH558 flew for the last time in October 2015, before also being kept in taxiable condition at Doncaster Sheffield Airport.

Despite its radical and unusual shape, the airframe was built along traditional lines. Except for the most highly stressed parts, the whole structure was manufactured from standard grades of light alloy. The airframe was broken down into a number of major assemblies: the centre section, a rectangular box containing the bomb-bay and engine bays bounded by the front and rear spars and the wing transport joints; the intakes and centre fuselage; the front fuselage, incorporating the pressure cabin; the nose; the outer wings; the leading edges; the wing trailing edge and tail end of the fuselage; the wings were not sealed and used directly as fuel tankage, but carried bladders for fuel in the void spaces of the wings; and there was a single swept tail fin with a single rudder on the trailing edge.

A five-man crew, the first pilot, co-pilot, navigator radar, navigator plotter and air electronics officer (AEO) was accommodated within the pressure cabin on two levels; the pilots sitting on Martin-Baker 3K (3KS on the B.2) ejection seats whilst on the lower level, the other crew sat facing rearwards and would abandon the aircraft via the entrance door. The original B35/46 specification sought a jettisonable crew compartment, this requirement was removed in a subsequent amendment, the rear crew's escape system was often an issue of controversy, such as when a practical refit scheme was rejected. A rudimentary sixth seat forward of the navigator radar was provided for an additional crew member; the B.2 had an additional seventh seat opposite the sixth seat and forward of the AEO. These seats were no more than cushions, a full harness and an oxygen and intercom facility. The visual bomb-aimer's compartment could be fitted with a T4 (Blue Devil) bombsight, in many B.2s this space housed a vertically mounted Vinten F95 Mk.10 camera for assessing simulated low-level bombing runs.

Fuel was carried in 14 bag tanks, four in the centre fuselage above and to the rear of the nosewheel bay and five in each outer wing. The tanks were split into four groups of almost equal capacity, each normally feeding its respective engine though cross-feeding was possible. The centre of gravity was automatically maintained by electric timers which sequenced the booster pumps on the tanks. B.2 aircraft could be fitted with one or two additional fuel tanks in the bomb-bay.
Despite being designed before a low radar cross-section (RCS) and other stealth factors were ever a consideration, a Royal Aircraft Establishment technical note of 1957 stated that of all the aircraft so far studied, the Vulcan appeared by far the simplest radar echoing object, due to its shape: only one or two components contributed significantly to the echo at any aspect, compared with three or more on most other types.
