Strategic Defence and Security Review 2010

The Strategic Defence and Security Review 2010 was announced by the formed Conservative-Liberal Democrat coalition government of the United Kingdom in May 2010, and published on 19 October 2010.

[14] The SDSR proposed that one of the two Queen Elizabeth-class aircraft carriers currently under construction would be certain to be commissioned, with the fate of the other left undecided.

[1] However, in May 2014 it was announced by Prime Minister David Cameron that the second carrier, Prince of Wales, would be brought into service alongside Queen Elizabeth.

The review had led to wide-ranging cuts to the Armed Forces, which were widely criticised for damaging the capabilities of the British military.

[27] The review was subsequently criticized for leaving Britain unprepared in a changing international environment, particularly in relation to its ability to retain trained personnel.

The number of Challenger 2 tanks would be cut by 40%.
HMAS Choules , previously RFA Largs Bay , was sold to the Royal Australian Navy following the SDSR.
The Harrier GR9 was retired in order to maintain the Tornado as the RAF's main strike aircraft until the Typhoon matured. The latter and the Lockheed Martin F-35 Lightning II would constitute the RAF's fast jet fleet in the future.
The Nimrod MRA4 was cancelled and all airframes scrapped.
