BAE Systems Nimrod MRA4 : ウィキペディア英語版 | BAE Systems Nimrod MRA4
The BAE Systems Nimrod MRA4 was a maritime patrol and attack aircraft intended to replace the Hawker Siddeley Nimrod MR2. The rebuilt aircraft would have extended the operating life of the Nimrod fleet by several decades and significantly improved the aircraft by installing more efficient Rolls-Royce BR700 turbofan jet engines to almost double the flight range. The conversion of the flight deck to a digital glass cockpit would have simplified control operations and reduced crew requirements. New detection systems were to be installed, as well as additional weapons for anti-submarine warfare. However the project was subject to significant delays due to cost over-runs and contract re-negotiations. This was partly due to difficulties combining refurbished Nimrod MR2 fuselages, which had not been built to a common standard, with newly built wings. The numbers of aircraft to be procured fell from 21 to nine over a course of years, while costs continued to climb. The MRA4 was ultimately cancelled in 2010 as a result of the Strategic Defence and Security Review, at which point it was £789 million over-budget and over nine years late. There is no direct replacement under development. The roles intended for the MRA4 are filled by existing assets such as the Type 23 Frigate and the Merlin helicopter. ==Development==
