Instead of building a new class of its own cruisers, the Royal Navy decided that it could address the threat posed via low-level attack runs performed by Buccaneers, so low as to exploit the ship's radar horizon to minimise the opportunity for being fired upon.
During its service life, it would be modified to carry anti-ship missiles, allowing it to attack vessels from a stand-off distance and thus improve its survivability against modern ship-based anti-aircraft weapons.
[3] To counter this threat, the Royal Navy decided not to use a new ship class of its own, but instead introduce a specialised strike aircraft employing conventional or nuclear weapons.
[21] Blackburn's first attempt to sell the Buccaneer to the Royal Air Force (RAF) occurred in 1957–1958, in response to the Air Ministry Operational Requirement OR.339, for a replacement for the RAF's English Electric Canberra light bombers, with supersonic speed, and a 1,000-nautical-mile (1,900 km; 1,200 mi) combat radius; asking for an all-weather aircraft that could deliver nuclear weapons over a long range, operate at high level at Mach 2+ or low level at Mach 1.2, with STOL performance.
Self-defence was improved by the addition of the AN/ALQ-101 electronic countermeasures (ECM) pod (also found on RAF's SEPECAT Jaguar GR.3), chaff and flare dispensers, and AIM-9 Sidewinder capability.
The 2* would have featured newer equipment; such as head-up displays and onboard computers from the cancelled Hawker Siddeley P.1154 VTOL aircraft, it would have also adopted the same radar system as that being developed for the TSR-2.
It had a crew of two in a tandem-seat arrangement with the observer seated higher and offset from the pilot to give a clear view forwards to enable him to assist in visual search.
Its operational profile included cruising at altitude (for reduced fuel consumption) before descending, just outside the anticipated enemy radar detection range, to 100 feet (30 m) for a 500-knot (930 km/h; 580 mph)[32] dash to and from the target.
[33] To illustrate, in May 1966, an S.2 launched from HMS Victorious in the Irish Sea, performed a low-level simulated nuclear weapon toss on the airfield at Gibraltar and returned to the ship, a 2,300-mile (3,700 km) trip[32] The aircraft had an all-weather operational capability provided by the pilot's head-up display and Airstream Direction Detector, for example, and the observer's navigation systems and fire control radar.
Red Beard had an explosive yield in the 10 to 20 kiloton range; and was mounted on a special bomb bay door, into which it nested neatly to reduce aerodynamic buffet on the launch aircraft.
[41] The Buccaneer also featured four underwing hard points capable of mounting 1,000-pound (450 kg) bombs, missiles, fuel tanks, or other equipment such as flares;[35] later developments saw the adoption of wing-mounted electronic warfare and laser designator pods.
A consequence of the blown wing was that the engines were required to run at high power for low-speed flight in order to generate sufficient compressor gas for blowing.
Blackburn's solution to this situation was the adoption of a large air brake; this addition also allowed an overshooting aircraft to pull away more quickly during a failed landing attempt.
Considerable effort went into ensuring that metal fatigue would not be a limiting factor of the Buccaneer's operational life, even under the formidable conditions imposed of low level flight.
[62] On 28 March 1967, Buccaneers from RNAS Lossiemouth bombed the shipwrecked supertanker Torrey Canyon off the western coast of Cornwall to make the oil burn in an attempt to avoid an environmental disaster.
In 1972, Buccaneers of 809 Naval Air Squadron operating from Ark Royal took part in a 1,500-mile (2,400 km) mission to show a military presence over British Honduras (now Belize) shortly before its independence, to deter a possible Guatemalan invasion in pursuit of its territorial claims over the country.
[63] The Buccaneer also participated in regular patrols and exercises in the North Sea, practising the type's role if war had broken out with the Soviet Union.
Measures such as the withdrawal of most British military forces stationed East of Suez were viewed as reducing the need for aircraft carriers, and fixed-wing naval aviation in general.
[66] The Royal Navy would replace the naval strike capability of the Buccaneer with the smaller V/STOL-capable British Aerospace Sea Harrier, which were operated from their Invincible-class aircraft carriers.
[67] After the General Dynamics F-111K was cancelled in early 1968, due to the programme suffering serious cost escalation and delays, the RAF was forced to look for a replacement that was available and affordable, and reluctantly selected the Buccaneer.
Opportunities for Buccaneer squadrons to engage in realistic training were limited, and so when the US began its Red Flag military exercises at Nellis Air Force Base in 1975, the RAF became keenly interested.
The entire RAF Buccaneer fleet was grounded in February 1980; subsequent investigation discovered serious metal fatigue problems to be present on numerous aircraft.
It was decided that a number of Tornado GR1s would be modified for compatibility with the Sea Eagle missile, and take over the RAF's maritime strike mission, and the Buccaneer would be retired early.
These nuclear weapons, containing highly enriched uranium, with an estimated explosion yield of 10-18 kilotons, were designed for delivery by either the Buccaneer or the Canberra bomber.
[81] SAAF Buccaneers saw active service in the 1970s and 1980s during the South African Border War, frequently flying over Angola and Namibia, launching attacks upon SWAPO guerilla camps.
During a ground offensive, Buccaneers would often fly close air support (CAS) missions armed with anti-personnel rockets, as well as performing bombardment operations.
[82] Buccaneers played a major role in the Battle of Cassinga in 1978, being employed in repeated strikes upon armoured vehicles, including enemy tanks, and to cover the withdrawal of South African and alligned ground forces from the combat zone.
[83] The Buccaneer was capable of carrying heavy load outs over a long range, and could remain in theatre for longer than other aircraft, making it attractive for the CAS role.
[79] Early in the Buccaneer programme, the United States Navy had expressed mild interest in the aircraft, but quickly moved on to the development of its comparable Grumman A-6 Intruder.
[85] The West German Navy showed a greater interest,[86] and considered replacing its Hawker Sea Hawks with the type, although it eventually decided on the Lockheed F-104G for its maritime strike requirement.
