The first Vulcan B.1 XA889 was used for the flight clearances of the Olympus 102 and 104. , The Avro 732 was a 1956 proposal for a supersonic development of the Vulcan and would have been powered by 8 de Havilland Gyron Junior engines.
, As Avro had no flight experience of the delta wing, the company planned two smaller experimental aircraft based on the 698, the one-third scale model 707 for low-speed handling and the one-half scale model 710 for high-speed handling. A cruising speed of 500 knots (580 mph; 930 km/h) at heights between 35,000 and 50,000 ft (11,000 and 15,000 m) was specified. , Required to tender by the end of April 1947, work began on receipt of Specification B.35/46 at Avro, led by technical director Roy Chadwick and chief designer Stuart Davies; the type designation was Avro 698.
Twenty-eight B.Mk 1s were converted in this fashion with conversions taking place from 1959 into 1963.
Yellow Sun Mk 2 was the first British thermonuclear weapon to be deployed, and was carried on both the Vulcan and Handley Page Victor.
Decca Doppler 72 replaced Green Satin in the B.2 around 1969 A continuous display of the aircraft's position was maintained by a ground position indicator (GPI).
Roe and Company (Avro) designed the Vulcan in response to Specification B.35/46. A second 707A, WZ736 and a two-seat 707C, WZ744 were also constructed but they played no part in the 698's development. 35 and 617 Squadron, also had secondary maritime reconnaissance role. In the mid-1970s nine Vulcans were adapted for maritime radar reconnaissance operations, redesignated as B.2 (MRR).
During trials in July 1954, VX777 was substantially damaged in a heavy landing at Farnborough.
, The squadron also inherited its secondary role of air sampling from No.  No.  In September 1955, Falk, flying the second production B.1 XA890, amazed crowds at the Farnborough Air Show by executing a barrel roll on his second flypast in front of the SBAC president's tent.  In January 1953, VX770 was grounded for the installation of wing fuel tanks, Armstrong Siddeley ASSa.6 Sapphire engines of 7,500 lbf (33 kN) thrust and other systems; it flew again in July 1953. 12 Squadron 1964–1967, moved in from Coningsby in 1964 until it disbanded in 1967.
The same number of the rival Handley Page design were also ordered. The high speed 707A, WD480, followed in July 1951.
The Vulcan formed an integral part of the British strategic nuclear air arm throughout the height of the Cold War years and could also double as a conventional bomber, as it did in the British Falklands War against Argentina - interestingly enough assisted with in-flight refueling by a tanker form of the Handley Page Victor.
83 Squadron was the first operational squadron to use the bomber, at first using borrowed Vulcans from the OCU, and on 11 July 1956 it received the first aircraft of its own. More representative of production aircraft, it was lengthened to accommodate a longer nose undercarriage leg, featured a visual bomb-aiming blister under the cabin and was fitted with Bristol Olympus 100 engines of 9,750 lbf (43.4 kN) thrust. "V Force Arsenal: Weapons for the Valiant, Victor and Vulcan". ", "Falklands: FCO to MOD (sale of Vulcans to Argentina – no clearance given for sales – declassified 2012)", "Will 'howl' of the Vulcan bomber be heard over Bournemouth again? , 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. First flight of production aircraft 4 February 1955, delivered between June 1955 and December 1957.
 At the time, these missions held the record for the world's longest-distance raids.  Painted gloss white, the 698 prototype VX770 flew for the first time on 30 August 1952 piloted by Roly Falk flying solo. The results of the tests were classified until 1997. best top new controversial old q&a. Fildes, David. "Workhorse (V-Bombers: Test-bed Vulcan). The Vulcan's powered flying controls were hydraulically actuated but each powered flying control unit (PFCU) had a hydraulic pump which was driven by an electric motor. Both prototypes had almost pure delta wings with straight leading edges.
 From 1962 onwards, two jets in every major RAF base were armed with nuclear weapons and on standby permanently under the principle of Quick Reaction Alert (QRA). , As the prototype Vulcan VX770 was ready for flight prior to the Olympus being available, it first flew using Rolls-Royce Avon RA.3 engines of 6,500 lbf (29 kN) thrust.
 The B.1As were not strengthened, thus all were withdrawn by 1968. The chief of the air staff preferred a V-class of bombers, and the Air Council announced the following month that the 698 would be called Vulcan after the Roman god of fire and destruction. Unlike the proposed Avro 721 low-level bomber of 1952 or the Avro 730 supersonic stainless steel canard bomber dating from 1954 (cancelled in 1957 before completion of the prototype), the Type 732 showed its Vulcan heritage. This anticipated a government decision in January 1947 to authorise research and development work on atomic weapons, the U.S. Atomic Energy Act of 1946 (McMahon Act) having prohibited exporting atomic knowledge, even to countries that had collaborated on the Manhattan Project. 102, 103.
", Jones, Barry. The B.2 (MRR) was additionally fitted with the LORAN C navigation system. At around 2,500 ft (760 m) the aircraft commander instructed the crew to abandon the aircraft.
, Due to the delay of the 707 programme, the contribution of the 707B and 707A towards the basic design of the 698 was not considered significant, though it did highlight a need to increase the length of the nosewheel to give a ground incidence of 3.5 degrees, the optimum take-off attitude.
Delivered between September 1959 and December 1960, Delivered between July 1961 and November 1962, Delivered between February 1963 and January 1965, one aircraft not flown and used as a static test airframe, 105 ft 6 in (32.16 m) [99 ft 11 in (30.45 m) without probe], 9,280 imp gal (11,140 US gal; 42,200 l) / 74,240 lb (33,675 kg), 9,260 imp gal (11,120 US gal; 42,100 l) / 74,080 lb (33,602 kg), 0–1,990 imp gal (0–2,390 US gal; 0–9,047 l) / 0–15,920 lb (0–7,221 kg), 1,990 imp gal (2,390 US gal; 9,000 l) / 15,920 lb (7,221 kg), 2,985 imp gal (3,585 US gal; 13,570 l) / 23,880 lb (10,832 kg), 1 × rudder (duplex), 4 × elevators, 4 × ailerons, The first prototype VX770 had its Sapphire engines replaced with four 15,000 lbf (67 kN). , More influential than the 707 in the 698's design was wind-tunnel testing performed by the Royal Aircraft Establishment at Farnborough, which indicated the need for a wing redesign to avoid the onset of compressibility drag which would have restricted the maximum speed.
A popular feature of XH558 at flypasts and air shows was the so-called 'Vulcan Howl', a distinctive sound made by some Vulcan airframes when the engines were at approximately 90 percent power. 617 Squadron 1958–1981, formed in 1958 to operate the B.1, reformed to operate the B.2 in 1961 until disbanded in 1981. The RAF would have transferred several V-bombers, including Vulcans, for interim use by the Royal Australian Air Force (RAAF) if they had purchased the TSR-2, but the RAAF selected the F-111C.. As such, the aircraft was fitted with chaff dispensers, a tail warning radar ("Red Steer"), a radar warning receiver, and jammers.

Vulcan B.1 XA903, surplus to Blue Steel trials, was converted to a similar layout to XA894 to flight test the Olympus 593 Concorde installation. 543 Squadron, No.
These were quickly replaced by Armstrong Siddeley Sapphire ASSa.6 engines of 7,500 lbf (33 kN) thrust. The first flight was on 1 October 1966 and testing continued through to June 1971.
Anticipating even more powerful engines, the air intakes were deepened on the 11th (XH557) and subsequent aircraft. After the Falklands War of 1982, the Vulcan's career as a dedicated bomber was all but over. The Valiant retained U.S. nuclear weapons assigned to SACEUR under the dual-key arrangements.
 In the B.2, these were replaced by eight elevons.
Aircraft of comparable role, configuration, and era, British jet-powered delta wing strategic bomber, XH558 performs its first post-restoration public display on 5 July 2008, Proposed developments and cancelled projects.
The captain shut the engine down and the AEO reported flames coming from the area of No.2 engine, just behind the deployed, On 3 June 1982, Vulcan XM597 broke its probe while attempting to refuel in flight, while returning from a mission over the, Austin, Steve. Two other surviving Vulcans, XL426 and XM655 are also kept in taxiable condition in the UK, and are periodically displayed, one at Southend Airport, and the other at Wellesbourne Mountford Airfield . An auto-mach trimmer was introduced to give a nose-up pitching moment, but more than was necessary just to counteract the diving tendency, so that the control column had to be pushed rather than pulled to maintain level flight.
On 25 May 1965, Vulcan B.2 XM576 crash-landed at, On 11 February 1966, Vulcan B.2 XH536 of IX SQN, On 6 April 1967, Vulcan B.2 XL385 burnt out on the runway at RAF Scampton at the beginning of its take-off run.
After being grounded, it was later restored to flight by the Vulcan To The Sky Trust and displayed as a civilian aircraft from 2008 until 2015, before being retired a second time for engineering reasons. , Five Vulcans were selected to participate in the operation. Aerei magazine, Delta Editions, Parma, November 1996, p. 56.
In June 1961, one of them took off from RAF Scampton to Sydney, with an 18,507 km long journey, flown in only a bit more than 20 hours and three air refuellings.
