The Hawker Siddeley Nimrod was a maritime patrol aircraft developed and operated by the United Kingdom. It was an extensive modification of the de Havilland Comet, the world's first operational jet airliner. It was originally designed by de Havilland's successor firm, Hawker Siddeley. Further development and maintenance work was undertaken by Hawker Siddeley's successor companies, British Aerospace and BAE Systems, respectively. The Nimrod MR 1 / MR 2's were primarily fixed-wing aerial platforms for anti-submarine warfare operations. Secondary roles included maritime surveillance and anti-surface warfare. It served from the early 1970s until March 2010. The intended replacement was to be the extensively rebuilt Nimrod MR2s designated Nimrod MRA 4. However, due to considerable delays, repeated cost overruns, and financial cutbacks, the development of the MRA 4 was abandoned in 2010. In addition to the three maritime reconnaissance variants, two further Nimrod types were developed. The RAF operated a small number of the Nimrod R1, an electronic intelligence gathering variant. A dedicated airborne early-warning platform, the Nimrod AW 3, was in development from the late 1970s to the mid-1980s. However, much like the MRA 4, considerable problems were encountered in development, and thus the project was canceled in 1986 in favor of an off-the-shelf solution in the Boeing E-3 Sentry. All Nimrod variants had been retired by mid-2011. Development: - On June 4, 1964, the British government issued Air Staff Requirement 381 to replace the Avro Shackleton. Such a replacement was necessitated by the rapidly approaching fatigue life limits of the RAF's Shackleton fleet. There was a great deal of interest in the requirement from both British and foreign manufacturers, offering various options, including the Lockheed P-3 Orion, the Braga Atlantic, and derivatives of the Hawker Siddeley Trident, BAC One-Eleven, Vickers VC10, and de Havilland Comet. - On February 2, 1965, British Prime Minister Harold Wilson...
