 An order to supply the Egyptian Air Force was received, but this was blocked by the British government as part of a general ban on supplying arms to Egypt.Instead, the RAF took over the order and put them into service as an interim measure between the retirement of the de Havilland Mosquito night fighter and the full introduction of the Meteor night fighter.Removal of the radar from the night fighter and fitting of dual controls resulted in a jet trainer model of the aircraft, the "DH.115 Vampire" which entered British service as the "Vampire T.11".
