Development of the de Havilland Goblin
began in 1941 with the Halford H1 with a
design thrust of 3000 lb. The engine passed a
25 hr special category test in September 1942
and was cleared for flight at 2000 lb thrust.
This took place in a Gloster Meteor on 5
March 1943 and was also the first flight of that
aircraft type. In September 1943 the first flight
De Havilland H1 Goblin of a de Havilland DH100 Vampire was made
with a Goblin of 2300 lb thrust.
