In the first half of the 1960's there were 16 visits to Australia, spread over about two years, by Vulcan 2's from Scampton. Each delivered a missile to Edinburgh Field (Adelaide) for the Blue Steel trials programme. The inbound and outbound route included Darwin.
There was strong competition amongst Scampton crews for the 16 'Blue Ranger' trips. They were divided as fairly as possible between the resident squadrons; 27, 83 and 617.
