The bombing of Dresden was a joint British and American aerial bombing attack on the city of Dresden, the capital of the German state of Saxony, during World War II. In four raids between 13 and 15 February 1945, 772 heavy bombers of the Royal Air Force (RAF) and 527 of the United States Army Air Forces (USAAF) dropped more than 3,900 tons of high-explosive bombs and incendiary devices on the city. The bombing and the resulting firestorm destroyed more than 1,600 acres (6.5 km2) of the city centre. An estimated 22,700 to 25,000 people were killed. Three more USAAF air raids followed, two occurring on 2 March aimed at the city's railway marshalling yard and one smaller raid on 17 April aimed at industrial areas.

Immediate German propaganda claims following the attacks and postwar discussions of whether the attacks were justified have led to the bombing becoming one of the moral causes clbres of the war. A 1953 United States Air Force report defended the operation as the justified bombing of a strategic target, which they noted was a major rail transport and communication centre, housing 110 factories and 50,000 workers in support of the German war effort.

Several researchers claim that not all of the communications infrastructure, such as the bridges, were targeted, nor were the extensive industrial areas which were located outside the city centre. Critics of the bombing have asserted that Dresden was a cultural landmark while downplaying its strategic significance, and claim that the attacks were indiscriminate area bombing and not proportionate to the military gains. Some have claimed that the raid constituted a war crime. Some people, including many in the German far-right, refer to the bombing as a mass murder, calling it "Dresden's Holocaust of bombs".In the decades since the war, large variations in the claimed death toll have fuelled the controversy, though the numbers themselves are no longer a major point of contention among historians.:334,482 In March 1945, the German government ordered its press to publish a falsified casualty figure of 200,000 for the Dresden raids, and death tolls as high as 500,000 have been claimed. The city authorities at the time estimated up to 25,000 victims, a figure that subsequent investigations supported, including a 2010 study commissioned by the city council. One of the main authors responsible for inflated figures being disseminated in the West was Holocaust denier David Irving, who subsequently announced that he had discovered that the documentation he had worked from had been forged, and the real figures supported the 25,000 number.

The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain.The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security". The RAF describes its mission statement as "... [to provide] an agile, adaptable and capable Air Force that, person for person, is second to none, and that makes a decisive air power contribution in support of the UK Defence Mission". The mission statement is supported by the RAF's definition of air power, which guides its strategy. Air power is defined as "the ability to project power from the air and space to influence the behaviour of people or the course of events".Today, the Royal Air Force maintains an operational fleet of various types of aircraft, described by the RAF as being "leading-edge" in terms of technology. This largely consists of fixed-wing aircraft, including those in the following roles: fighter and strike, airborne early warning and control, intelligence, surveillance, target acquisition, and reconnaissance (ISTAR), signals intelligence (SIGINT), maritime patrol, air-to-air refuelling (AAR) and strategic & tactical transport. The majority of the RAF's rotary-wing aircraft form part of the tri-service Joint Helicopter Command in support of ground forces. Most of the RAF's aircraft and personnel are based in the UK, with many others serving on global operations (principally over Iraq and Syria) or at long-established overseas bases (Ascension Island, Cyprus, Gibraltar, and the Falkland Islands). Although the RAF is the principal British air power arm, the Royal Navy's Fleet Air Arm and the British Army's Army Air Corps also operate armed aircraft.
