The first operational jet fighter squadron was No. 616, based at Culmhead, Somerset, equipped with Spitfire F.Mk VIIs when its first two Meteor F.Mk Is arrived on 12 July 1944. On 21 July the squadron moved to Manston, Kent, receiving more Meteors on 23 July to form a detached flight of seven. The first operational sorties were flown on 27 July, and on 4 August, near Tonbridge, Flying Officer Dean destroyed the first Vl fiying bomb to be claimed by a jet fighter, using the Meteor's wingtip to tip it over into a spin after the aircraft's four 20 mm cannon had jammed. On the same day, Flying Officer Roger shot down a second V1 near Tenterden.
Conversion to Meteors was completed towards the end of August, and the autumn was spent preparing for operations on the continent. Between 10 and 17 October, however, four Meteors were detached to Debden, to take part in an exercise with the USAAF 2nd Bombardment Division and 65th Fighter Wing, to enable defensive tactics against the Luftwaffe's Messerschmitt Me 163 and Me 262 fighters to be devised. The first Meteor F.Mk III aircraft were delivered to Manston on 18 December, and on 17 January the squadron moved to Colerne, Wiltshire, where the remaining Meteor F.Mk Is were replaced. On 20 January 1945 one flight of No. 616's Meteors joined No. 84 Group, 2nd Tactical Air Force in Belgium, and in March No. 504 became the second Meteor F.Mk Ill unit to operate on the other side of the English Channel.
I'd think the Meteor is a no brainer given it was operational in a combat role in 7/44....
