RoleAirliner
National origin United Kingdom
Manufacturer Avro
Developed from Avro Vulcan

The Avro Atlantic (Avro 722) was a proposed civilian airliner version of the British Avro Vulcan strategic bomber. It was a response to a 1952 UK Ministry of Supply requirement for a new aircraft suitable for both military and civilian long-range roles. Civilian models of the Vickers Valiant and Handley Page Victor V-bombers were also planned for the same contract. The Vickers V-1000 won the contest over the Atlantic, but ultimately none of these designs would be built.

Development

In early June 1953, Sir Roy Dobson C.B.E., then Managing Director of A.V. Roe and Company, revealed [1] that the company was working on a project for a 100-ton airliner based on the Vulcan. The aircraft as initially envisaged, would have carried a flight crew of five (pilot, co-pilot, navigator and two engineering officers) as well as between 76 and 113 passengers in one of three separate configurations (luxury, basic and tourist) at speeds in excess of 600 mph (520 kn; 970 km/h) or Mach 0.9 in a pressurised cabin with an equivalent altitude of 8,000 ft (2,400 m) at 45,000 ft (14,000 m). [2] The chief designer of Avro at the time, after Roy Chadwick's death, was Stuart Davies. [3]

The Atlantic would have been powered either by Bristol Olympus or Rolls-Royce Conway engines. Artists illustrations at the time show passengers in a 12 ft 6 in (3.81 m) diameter fuselage, seated in two rows, two-abreast, with a single central aisle, with the seats facing towards the rear of the aircraft for safety reasons. [2] The aircraft was initially depicted in illustrations and 1/24-scale models using the original Vulcan wing planform with a straight-line, swept back leading edge, but a 1955 design revision showed the later Phase 2 'kinked' leading edge to overcome buffet during flight. It was anticipated that the Atlantic would be complete by 1958, and initial discussions were held with British Overseas Airways Corporation (BOAC) regarding the viability of the proposal. Avro is reported to have considered a civilian version of the Vulcan as 'inevitable' in 1954–55, and insisted on an initial order of at least 25 aircraft before it would commence production; these orders were not forthcoming.

The Avro Vulcan 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, hence the riskiest option. Several reduced-scale aircraft, designated Avro 707s, were produced to test and refine the delta-wing design principles.

The Vickers Valiant was a British high-altitude jet bomber designed to carry nuclear weapons, and in the 1950s and 1960s was part of the Royal Air Force's "V bomber" strategic deterrent force. It was developed by Vickers-Armstrongs in response to Specification B.35/46 issued by the Air Ministry for a nuclear-armed jet-powered bomber. The Valiant was the first of the V bombers to become operational, and was followed by the Handley Page Victor and the Avro Vulcan. The Valiant was the only V bomber to have dropped live nuclear weapons.

The Avro 679 Manchester was a British twin-engine heavy bomber developed and manufactured by the Avro aircraft company in the United Kingdom.

The Handley Page Victor is a British jet-powered strategic bomber developed and produced by Handley Page during the Cold War. It was the third and final V bomber to be operated by the Royal Air Force (RAF), the other two being the Avro Vulcan and the Vickers Valiant. Entering service in 1958, the Victor was initially developed as part of the United Kingdom's airborne nuclear deterrent, but it was retired from the nuclear mission in 1968, following the discovery of fatigue cracks which had been exacerbated by the RAF's adoption of a low-altitude flight profile to avoid interception, and due to the pending introduction of the Royal Navy's submarine-launched Polaris missiles in 1969.

The Short SA.4 Sperrin was a British jet bomber design of the early 1950s, built by Short Brothers and Harland of Belfast. It first flew in 1951. From the onset, the design had been viewed as a fall-back option in case the more advanced strategic bomber aircraft, then in development to equip the Royal Air Force's nuclear-armed V bomber force, experienced delays; the Sperrin was not put into production because these swept-wing designs, such as the Vickers Valiant, were by then available.

The Avro Type 688 Tudor was a British piston-engined airliner based on Avro's four-engine Lincoln bomber, itself a descendant of the famous Lancaster heavy bomber, and was Britain's first pressurised airliner. Customers saw the aircraft as little more than a pressurised DC-4, and few orders were forthcoming, important customers preferring to buy US aircraft. The tailwheel undercarriage layout was also dated and a disadvantage.

The Avro 730 was a planned Mach 3 reconnaissance aircraft and strategic bomber that was being developed by Avro Aircraft for the Royal Air Force (RAF). It had been originally envisioned as a very high-speed aircraft to perform aerial reconnaissance missions, conforming with the requirements of Air Ministry Specification OR.330. Avro subsequently decided to modify the design of the proposed 730 in order to accommodate its arming with nuclear weapons; this change therefore meant that the type would be able to perform the nuclear weapons delivery mission as well, which had been called for under Air Ministry Specification RB.156T which sought a high speed reconnaissance-bomber aircraft.

The Vickers-Armstrongs V-1000 was a proposed jet-powered cargo aircraft that was designed to meet a requirement issued by the British Ministry of Supply which sought a strategic transport for the Royal Air Force (RAF) to support its strategic bomber fleet, particularly the V-bombers. The design bears many similarities to the Vickers Valiant, one of the V-bombers, but also featured substantial changes. In addition to its military application, both the Ministry and Vickers also intended to use the same basic design as the VC7, a six-abreast trans-Atlantic jet airliner for British Overseas Airways Corporation (BOAC).
