the South Atlantic to provide air defence to the Falkland Islands, with the McDonnell Douglas Phantom FGR2 based at RAF Mount Pleasant which was built in 1984. Post-Cold War With the end of the Cold War and the collapse of the Soviet Union, the RAF's focus returned to expeditionary air power. Since 1990, the RAF has been involved in several large-scale operations, including the 1991 Gulf War, the 1999 Kosovo War, the 2001 War in Afghanistan, the 2003 invasion and war in Iraq and the 2011 intervention in Libya. The RAF's 90th anniversary was commemorated on 1 April 2008 by a flypast of the RAF's Aerobatic Display Team the Red Arrows and four Eurofighter Typhoons along the River Thames, in a straight line from just south of London City Airport Tower Bridge, the London Eye, the RAF Memorial and (at 13.00) the Ministry of Defence building. Four major defence reviews have been conducted since the end of the Cold War: the 1990 Options for Change, the 1998 Strategic Defence Review, the 2003 Delivering Security in a Changing World and the 2010 Strategic Defence and Security Review (SDSR). All four defence reviews have resulted in steady reductions in manpower and numbers of aircraft, especially combat aircraft such as fast-jets. As part of the latest 2010 Strategic Defence and Security Review, the BAE Systems Nimrod MRA4 maritime patrol aircraft was cancelled due to over spending and missing deadlines. Other reductions saw total manpower reduced by 5,000 personnel to a trained strength of 33,000 and the early retirement of the Joint Force Harrier aircraft, the BAE Harrier GR7/GR9. In recent years, fighter aircraft on Quick Reaction Alert (QRA) have been increasingly required to scramble in response to Russian Air Force aircraft approaching British airspace. On 24 January 2014, in the Houses of Parliament, Conservative MP and Minister of State for the Armed Forces, Andrew Robathan, announced that the RAF's QRA force had been scrambled almost thirty times in the last three years: eleven times during 2010, ten times during 2011 and eight times during 2012.RAF Coningsby in Lincolnshire and RAF Lossiemouth in Moray both provide QRA aircraft, and scramble their Typhoons within minutes to meet or intercept aircraft which give cause for concern. Lossiemouth generally covers the northern sector of UK airspace, while Coningsby covers the southern sector. Typhoon pilot Flight Lieutenant Noel Rees describes how QRA duty works. "At the start of
