C-flight trained crews to fly the Vickers Wellington medium bomber until demand reduced and it left on 1 September 1944.

During the winter of 1944 and 1945, many stations located further south were fog-bound which resulted in Milltown being used as a diversion airfield for large numbers of bomber aircraft.

This included on 21 December 1944 when forty-six aircraft diverted to Milltown, a mixture of Avro Lancasters, Boeing Fortresses and Liberators.

That mission was unsuccessful, however a further attempt known as Operation Catechism, finally resulted in the battleship being sunk near Tromsø on 12 November 1944.

The unit temporarily moved to Lossiemouth whilst one of Milltown's runways was repaired during January 1945, continuing patrols until 2 June and then returning to RAF St. Eval in July.

Between 1958 and 1962, the Lossiemouth Handling Squadron flew the Gloster Meteor TT.20, a target towing version of the jet fighter.

1 Squadron in March and April 1971, supported by nine Hercules, three Hawker Siddeley Andovers, seven Armstrong Whitworth Argosys and a Short Belfast; and four Harriers in 1972 for Exercise Snowy Owl.
