Designed and initially produced by Blackburn Aircraft at Brough, it was later officially known as the Hawker Siddeley Buccaneer when Blackburn became a part of the Hawker Siddeley Group, but this name is rarely used. The Buccaneer was a mid-wing, twin-engine aircraft. 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) dash to and from the target. Targets might be ships-at-sea or large shore-based installations at long range from the launching aircraft-carrier. 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. The Buccaneer was one of the largest aircraft to operate from British aircraft carriers, and continued operating from them until the last conventional carrier was withdrawn in 1978. During its service, the Buccaneer was the backbone of the Navy's ground strike operations, including nuclear strike.
