Editing Westland Welkin (section)

==Operational history==
By the time the '''Welkin Mk.I''' was complete and in production, it was apparent that the ''Luftwaffe'' was no longer conducting high altitude missions, due largely to successful interceptions by [[Supermarine Spitfire (early Merlin powered variants)#Mk VI (Type 350)|specially modified Supermarine Spitfires]]. Only 77 complete Welkins were produced, plus a further 26 as engine-less airframes.{{sfn|Velek|Ovčáčík|Susa|2005|p=3}} Although two Welkins served with the [[Fighter Interception Unit]] based at [[RAF Wittering]] from May to November 1944, where they were used to gain experience and formulate tactics for high altitude fighter operations, the Welkin was never used operationally by the RAF.{{sfn|Thetford|1962|p=552}}
