The de Havilland Vampire is a British jet fighter developed and manufactured by the de Havilland Aircraft Company. It had the distinction of being the second jet fighter, following after the Gloster Meteor, to be operated by the RAF and the first to be powered by a single jet engine.

The de Havilland Vampire was the second of the RAF's first-generation, post-Second World War jet fighters to enter service. It began life as an interceptor but was soon re-tasked in the day fighter/ground attack roles with the 2nd Tactical Air Force in Germany from 1948 to 1954 and with the RAF's Middle and Far East Air Forces.

Throughout its forty-six-year career, it collected many notable firsts: it was the first jet fighter to cross the Atlantic; the first jet to land on an aircraft carrier; and the first jet trainer on which student pilots qualified for their 'Wings'.

In addition to playing a full part in the RAF's order of battle during the 1940s and 1950s, the Vampire also served with the Fleet Air Arm and became an export success story for the British aircraft industry with hundreds sold to air forces worldwide.

For a brief period during the 1950s, the Vampire formed the backbone of the RAF's night-fighter force and between 1952 and 1967 the Vampire trainer was responsible for a steady flow of trained pilots for the RAF, Royal Navy and foreign air forces. This comprehensive history covers the Vampire's development and operational service.

Sir Geoffrey de Havilland, founder of the de Havilland World Enterprise, one of the first global manufacturing companies, was one of Britain’s aviation pioneers. Geoffrey and his colleague, Frank Hearle had designed and built their first aircraft, powered by an engine designed by Geoffrey, and neither of them had even seen an aircraft before. The first example crashed on the initial attempt at flight in December 1909, due to instability and lack of experience by the novice pilot. The engine was salvaged and the wreck taken back to the workshop in Fulham where a more successful aircraft was constructed and flown by Geoffrey on 10 September 1910 at the remote site of Seven Barrows near Newbury. With funds nearly depleted, Geoffrey was able to sell the aeroplane to the Royal Aircraft Factory at Farnborough for £400, at the same time gaining work for himself and Frank.

At the Royal Aircraft Factory Geoffrey was responsible for the design and test flying of his own aircraft, the most significant being the BE.2, which he flew to a height record of 10,560 feet with a passenger on 12 August 1912. With the outbreak of WWI, Geoffrey and Frank joined the Aircraft Manufacturing Company (Airco) at Hendon where the D.H series of designs was started with the DH.1, the most successful type being the DH.4 two seat day bomber, which was faster than many of the contemporary fighters. During WWI, Airco also produced fighters, trainers and the DH.10 twin engine bomber, all designed by Geoffrey de Havilland.

Development of the Vampire was continuing in parallel with the de Havilland Goblin jet engine developed by Major Frank Halford and his team, the aircraft being flown for the first time by Geoffrey de Havilland Jnr on 20 September 1943, 16 months after the go-ahead, achieving 500 mph in 1944, although by the time production was established, the war was over. The Vampire featured a twin fuselage boom layout with the tail across the rear, to allow a more efficient short jet pipe, maintaining as much thrust as possible.

The Vampire was progressively developed, not only for the RAF, but for export widely, over 1,500 being built mainly be English Electric at Preston and de Havilland at Broughton. As well as British production, Vampires were built under license in Switzerland, Italy, India, France and Australia. A Vampire was the first jet aircraft to land on an aircraft carrier, when Lt Cdr Eric ‘Winkle’ Brown landed and took off from HMS Ocean on 3 December 1945.
