Originally named the "Spider Crab," the aircraft was entirely a de Havilland project, exploiting the company's extensive experience in building with moulded plywood for aircraft construction. Many of the basic design features were first used in their Mosquito bomber. It had conventional straight mid-wings and a single jet engine placed in an egg-shaped, aluminium-skinned fuselage, exhausting in a straight line.

Geoffrey de Havilland Jr, the de Havilland chief test pilot and son of the company's founder, test flew prototype LZ548/G on its maiden flight 20 September 1943 from Hatfield. The flight took place only six months after the Meteor's maiden flight. Although eagerly taken into service by the RAF, it was still being developed at war's end, and never saw combat in the Second World War.
Almost 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.
