Joint Defence Space Research Facility Pine Gap (now Joint Defence Facility, Pine Gap) commences operations.

A signals intelligence station managed jointly by the Central Intelligence Agency, the US National Security Agency and the US National Reconnaissance Office, during the Cold War, Pine Gap played an essential role in the verification of some major arms control agreements.

In the post-Cold War era, Pine Gap is a key component of the ECHELON global surveillance network, a Sigint surveillance program operated by the Five Eyes intelligence alliance (US, Australia, Canada, New Zealand and the UK).
