De Haviland's had long been famous for it's range of wooden civil aircraft and had shown with the Mosquito and Hornet that innovative wooden construction could also be
applied to very high performance aircraft. Also innovative, was De Haviland's determination to produce a jet engine of their own design in cooperation with Major F.B. Halford.
The Vampire represented a creative and elegant approach to the problems inherent in producing a first generation jet fighter. In contrast with the Gloster Meteor which used
a twin engined layout to compensate for the low power offered by the primitive jet engines.

The shape was dictated by the engine. In contrast to the twin-engined Meteor, De Havilland chose a single-engined aircraft and a twin-boom layout adopted to reduce the
length of the jetpipe, in order to get maximum engine performance from the low-powered engines of the time. The fuselage nacelle was constructed from Mosquito-style
plywood sandwich with balsa wood as a stabilising fillingAlmost 3,300 Vampires were built, a quarter of them under licence in other countries.
The Vampire design was also developed into the de Havilland Venom fighter-bomber as well as naval Sea Vampire variants.The Vampire F1 entered service in 1946,
being the first RAF fighter with a top speed exceeding 500 mph, the first jet to take off from and land on an aircraft carrier and in 1948, a new world altitude record of 18,119m
and the Vampire made the first Atlantic crossing by jet.
Due to the extreme simplicity and economy of the Vampire's construction the Vampire was exported widely providing a painless introduction to jet flying for many air forces.

The Sea Vampire was also the first jet powered aircraft to land on and take off from an aircraft carrier, flown by Captain Eric 'Winkle' Brown RN (HMS Ocean, 1945)
