In January 1941, Sir Henry Tizard approached de Havilland to create this jet-powered fighter without an official RAF specification. Major Frank Halford developed its engine based on earlier designs by Frank Whittle. By April 1941, prototype testing commenced despite early power limitations of jet engines.
The aircraft's design featured engineering innovations like a minimized power loss from its jet pipe and a twin-boom layout preventing tail interference from exhausts. Approved for RAF service in July 1941 amid concerns over weight and performance capabilities, its design evolved to include wood-metal construction by November that year.
On September 20th, 1943, Geoffrey de Havilland Jr. piloted its maiden flight at Hatfield Aerodrome despite delays due to engine availability issues resolved through modifications addressing directional instability.
An initial order for 120 Vampire Mk I aircraft expanded to 300 as WWII ended; development continued post-war with variants like DH.113 night fighter equipped with advanced radar systems extensively used globally.
Despite attempts at engine upgrades failing initially—eventually successful models powered by Rolls-Royce Nene entered service with Australian & French forces—the Vampire III variant designed for extended range via drop tanks emerged successfully among others produced totaling over three thousand units across thirty-one air forces worldwide.
"The Sea Vampire became" historically notable setting records including being "the first jet-powered aircraft" landing/taking off from carriers under Captain Eric Brown’s command on December third nineteen forty-five according BAE Systems reports alongside altitude record achievements reaching fifty-nine thousand four hundred feet above ground level established nineteen forty-eight amongst other experimental enhancements improving overall performance maintaining prominence within British aviation history well into subsequent decades following wartime period."
During combat operations globally spanning decades-long operational lifespan: Malayan Emergency deployment saw FB5 jets conduct ground-strike missions proving speed/firepower effectiveness; Mau Mau Uprising counterinsurgency efforts utilized rocket/bomb combinations demonstrating tropical climate adaptability leading eventually toward FB9 variant development incorporating refrigeration equipment enhancing pilot comfort amidst humid conditions further bolstered upgraded Goblin engines ensuring consistent high-performance levels maintained throughout diverse environmental settings encountered
