Vulcan production in full swing, 1957; via Garry Lakin
Piloted by Wing Commander Roly Falk, VX770 first flew on 30th August 1952 and, watched only by Avro employees and a small band of press, he showed just why he had fought for a fighter- style joystick instead of the traditional yoke. The first flight did not go entirely to plan - two objects were seen to detach from the aircraft and float to the ground. These turned out to be the triangular undercarriage doors attached to the rear of the main gear legs, and the aircraft flew without them for a short time afterwards. In 1953 the Type 698 was officially named the Vulcan, and surely there can not have been a more fitting appellation given to any aircraft? Several spectacular Farnborough appearances followed, including a full roll at the 1955 show (try that in a B-52!). Falk had actually rolled the Vulcan on returning to Avro's Woodford base after a previous Farnborough appearance - that time he did it so low and so noisily that he smashed all the skylight windows in the assembly building!

The prototype had first flown with Avon engines, as the Rolls-Royce BE.10s (later named Olympus) being developed were not yet ready; it was soon fitted with Armstrong-Siddeley Sapphires instead but only with the fitment of the Olympus was the aircraft's true potential realised. By August 1953, the second prototype, also fitted with the Olympus, was in the air also. Unfortunately, at higher speeds, the wing was suffering from buffeting during manouevres, and the problem was serious enough to require a partial re-design. The production B.1 gained a kinked and dropped leading edge, and a lengthened nose to accomodate extra fuel and simplify the nose gear leg retraction system. Delivery of production B.1s began in 1956 and the first squadron (83 Squadron) formed in May 1957 - but by this time the RAF already had a wary eye on the ever-increasing sophistication of the Soviet Union's defences.

The 1957 Defence White Paper spelled an end for many defence projects in the UK, reorganising the UK's defences to support the nuclear deterrent force. With the Vulcan as the tip of the nuclear spear, improving the B.1 was high on the agenda. More powerful engines, an electronic warfare (ECM) suite in a new larger tailcone, in-flight refuelling capability, an improved electrical system and further improved and larger wings formed the basis of a new variant - the B.2 (some B.1s had some B.2 improvements made to them, then being called B.1As). With longer range, the ability to carry a heavier payload and much improved self-defence measures in a vastly more powerful ECM suite, the B.2 made sure that missions into the Soviet Union wouldn't be the suicide mission they would have been with the B.1 - particularly when the switch was mode to low level penetration of enemy airspace. The fatigue life of all V-force aircraft would be reduced by low level operations, but the chances of radar detection were much lower, and with the application of camouflage the chances of visual acquisition from above were also minimised.

The nuclear capability of the B.2 was also improved compared to the B.1. Two nuclear weapons (Yellow Sun and Red Beard) could be carried. Even with the B.2's improvements, however, the delivery of free-fall nuclear weapons into the increasingly deadly defences of the Soviet Union was becoming far too dangerous a proposition. Intermediate range Thor missiles became a significant part of the UK's nuclear deterrent, but the flexibility of a manned bomber force was still important. The obvious way to improve the survivability of the V-force was to use stand-off missiles and accordingly Blue Steel was developed. This could be fired up to 100 miles away from the target. As on the Victor, Blue Steels were carried in a partially-recessed manner. The bomb bay area was modified accordingly and the lower tailfin of the missile would be folded over on the ground to give enough ground clearance. On launching the fin would fold down, the missile's rocket engines would fire, boosting it to high altitude and the Vulcan crew would turn for home, leaving Blue Steel to fly on towards the target independently. An improvement over the Blue Steel would have been the American's Skybolt missile, which was intended for use by B-52s and Vulcans. Vulcans would have been able to carry two, one under each wing, and many B.2s were built with suitable attachment points under their wings. However, the programme was a troubled one and despite it looking like becoming a success towards the end, the Americans cancelled it late on in development at the end of 1962.

In common with most British aircraft, a number of unusual proposals were made during the Vulcan's life, none of which came to anything. These include an airliner version (the Avro Atlantic), a fighter-support Vulcan which would have carried three Gnats semi-recessed in the fuselage and wings and even a vertical take-off Vulcan (complete with no less than ten lift engines in the bomb bay). Even the least ambitious proposal, the 'Phase 6' Vulcan, which would have had larger wings and tail and an extended fuselage housing a second crew (for very long missions) along with provision for extra bombs in pods on the wings, came to naught, not least because the Americans cancelled the troubled Skybolt nuclear missile that was to have been carried by the Phase 6 Vulcan (and indeed many B.2s).

The loss of Skybolt and the retirement of the obsolete Thor missile meant that the RAF was fielding a nuclear deterrent bomber force that was increasingly outmoded. With the arrival of Polaris ICBMs and associated submarines, the Royal Navy took over the RAF's nuclear deterrent role. Thus, the Vulcan would have flown for its entire service life without ever dropping a bomb in anger - had it not been for the Falklands war in 1982. While of limited tactical use, a succession of Vulcan bombing missions against the Argentine occupiers on the Falklands Islands proved that the UK still had a strategic bomber force to be reckoned with. While damage to Argentine ground forces was limited, the psychological effect was significant and the Argentines kept back a large portion of their air defence fighters to defend against attacks on their mainland.

The huge amount of tanker support required by the missions also resulted in the final version of the Vulcan - the K.2 tanker. Requested by the MoD during the Falklands war, a mere 51 days passed between request and delivery of the first K.2. The K.2 was basically a B.2 with an ugly box tacked underneath the tailcone (containing the drogue unit; hoses and drum unit were held within the ECM bay within the tailcone) and the bomb bay was filled with three huge fuel tanks. Huge white areas painted underneath the wings to help receiving aircraft line up on the tanker added their own final uglification. Two years after the Falklands War, in March 1984, the last Vulcan squadron was disbanded, leaving only the Vulcan Display Team to fly on. XL426 thrilled airshow visitors, until 1986 when it was offered for tender. Bought by Roy Jacobsen, now XL426 is now looked after at Southend airport by the Vulcan Restoration Trust. The sale of XL426 did not mean the end of the Vulcan Display Team though - it was replaced by XH558, which was to roar through the skies for many years, becoming the most famous Vulcan of all.

Many Vulcans ended up being scrapped, or burned as fire practice airframes. A few were thankfully preserved and sold to museums or private individuals. Unfortunately defence cuts began to bite into all of the UK's armed forces, and maintaining a single aircraft for display purposes could no longer be justified by the MoD's bean-counters. In early 1993, despite intensive public lobbying to keep her flying, XH558 was finally also offered for tender, retired from the RAF and sold to David Walton who looked after it for some years at Bruntingthorpe airfield in Leicestershire before selling it on to a company formed with the aim of returning her to the air. On 18th October 2007, they had managed just that.
