Many of the 300 missiles were expended in testing by 6 JSTU at RAF Valley and Woomera, South Australia from 1955–1957 using Meteor NF11 trials aircraft and subsequently by the Supermarine Swift fighters of No. 1 Guided Weapons Development Squadron at RAF Valley.
The last variant was the F Mk 7 and was the first Swift variant to be fitted with guided-missiles, being armed with the Fairey Fireflash air-to-air missile and was powered by a new Avon engine.
