Polaris
The Falstaff was part of the Chevaline programme to improve the Polaris programme. The Penetration Aids Carrier was capable of maneuvering a Falstaff rocket and dispensing missiles. According to John Pitfield, the PAC was launched in 1969, 1975, 1976 and 1978.Since the Australian government at the time was not in favour of nuclear weapons, the testing of the Falstaff vehicles on Australian soil had the potential to cause embarrassment. The details of over 4000 launches from the Woomera Range are still not fully released.
Before the revelation that the Falstaff rockets were part of a nuclear program, anti-nuclear campaigners in Australia had believed that testing ended in 1963.
