The ''Resolution'' class was a class of four nuclear ballistic missile submarines (SSBN) built for the Royal Navy as part of the UK Polaris programme. Each submarine was armed with up to 16 UGM-27 Polaris A-3 nuclear missiles. The class included , , and . They were built by Vickers Armstrong in Barrow-in-Furness and Cammell Laird in Birkenhead between 1964 and 1968. All four boats were based at HM Naval Base Clyde (HMS ''Neptune''), west of Glasgow, Scotland. The ''Resolution'' class was the launch platform for the United Kingdom's strategic nuclear deterrent from the late 1960s until 1994, when it was replaced by the carrying the Trident II. ==Background== During the 1950s and early 1960s, the United Kingdom's nuclear deterrent was based on the RAF's V-bombers. But in the early 1960s developments in radar and surface-to-air missiles made it clear that bombers were becoming vulnerable, and would be unlikely to penetrate Soviet airspace. Free-fall nuclear weapons would no longer be a credible deterrent. To address this problem, in May 1960 the British Prime Minister, Harold Macmillan arranged a deal with US President Eisenhower to equip the V bombers with the US-designed AGM-48 Skybolt. The Skybolt was a range ballistic missile that allowed the launching bombers to remain well away from Soviet defences and launch attacks that would be basically invulnerable. With this range, the V bombers would have to fly only a few hundred miles from their bases before being in range for an attack on Moscow. Under the agreement the UK's contribution to the program was limited to developing suitable mounting points on the Avro Vulcan bomber, installing the required guidance systems that fed the missiles updated positioning information, and development of a British version of the US W47 warhead to arm it, the RE.179 (). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Resolution-class submarine」の詳細全文を読む スポンサード リンク
