Pine Gap is the commonly used name for a US satellite surveillance base and Australian Earth station approximately 18 kilometres (11 mi) south-west of the town of Alice Springs, Northern Territory in the centre of Australia which is jointly operated by Australia and the United States. Since 1988, it has been officially called the Joint Defence Facility Pine Gap (JDFPG); previously, it was known as Joint Defence Space Research Facility.[1]

The station is partly run by the US Central Intelligence Agency (CIA), US National Security Agency (NSA), and US National Reconnaissance Office (NRO) and is a key contributor to the NSA's global interception effort, which included the ECHELON program.[2][3][4][5] The classified NRO name of the Pine Gap base is Australian Mission Ground Station (AMGS), while the unclassified cover term for the NSA function of the facility is RAINFALL.[6]

The base[edit]

The facilities at the base consist of a massive computer complex with 38 radomes protecting radio dishes[7] and has over 800 employees.[8] NSA employee David Rosenberg indicated that the chief of the facility was a senior CIA officer at the time of his service there.[9]:p 45–46[10]

The location is strategically significant because it controls United States spy satellites as they pass over one-third of the globe, including China, the Asian parts of Russia, and the Middle East.[7] Central Australia was chosen because it was too remote for spy ships passing in international waters to intercept the signal.[9]:p xxi The facility has become a key part of the local economy.[11]

Operational history[edit]

In late 1966, in the throes of the Cold War, a joint US–Australian treaty called for the creation of a US satellite surveillance base in Australia, to be titled the "Joint Defence Space Research Facility".[12] The purpose of the facility was initially referred to in public as "space research".[13] Operations started in 1970 when about 400 American families moved to Central Australia.[11]

Since the end of the Cold War in 1991 and the rise of the War on Terror in 2001, the base has seen a refocusing away from mere nuclear treaty monitoring and missile launch detection, to become a vital warfighting base for US military forces.[6] In 1999, with the Australian Government refusing to give details to an Australian Senate committee about the relevant treaties, intelligence expert Professor Des Ball from the Australian National University was called to give an outline of Pine Gap. According to Professor Ball, since 9 December 1966 when the Australian and United States governments signed the Pine Gap treaty, Pine Gap had grown from the original two antennas to about 18 in 1999, and 38 by 2017. The number of staff had increased from around 400 in the early 1980s to 600 in the early 1990s and then to 800 in 2017, the biggest expansion since the end of the Cold War.[citation needed]

Ball described the facility as the ground control and processing station for geosynchronous satellites engaged in signals intelligence collection, outlining four categories of signals collected:

Ball described the operational area as containing three sections: Satellite Station Keeping Section, Signals Processing Station and the Signals Analysis Section, from which Australians were barred until 1980. Australians are now officially barred only from the National Cryptographic Room (similarly, Americans are barred from the Australian Cryptographic Room). Each morning the Joint Reconnaissance Schedule Committee meets to determine what the satellites will monitor over the next 24 hours.

With the closing of the Nurrungar base in 1999, an area in Pine Gap was set aside for the United States Air Force's control station for Defense Support Program satellites that monitor heat emissions from missiles, giving first warning of ballistic missile launches. In 2004, the base began operating a new satellite system known as the Space-Based Infrared System, which is a vital element of US missile defense.[7]

Since the end of the Cold War, the station has mainly been employed to intercept and record weapons and communications signals from countries in Asia, such as China and North Korea. The station was active in supporting the wars in Yugoslavia, Afghanistan and Iraq and every US war since the September 11 attacks.[14][15]

The Menwith Hill Station (MHS) in the UK is operated by the NSA and also serves as ground station for these satellite missions.[6]

One of the station's primary functions is to locate radio signals in the Eastern Hemisphere, with the collected information fed into the US drone program.[16][17] This was confirmed by an NSA document from 2013, which says that Pine Gap plays a key role in providing geolocation data for intelligence purposes, as well as for military operations, including air strikes.[6]

On 11 July 2013, documents revealed through former NSA analyst Edward Snowden showed that Pine Gap, amongst three other locations in Australia and one in New Zealand, contributed to the NSA's global interception and collection of internet and telephone communications, which involves systems like XKEYSCORE.[6] Journalist Brian Toohey states that Pine Gap intercepts electronic communications from Australian citizens including phone calls, emails and faxes as a consequence of the technology it uses.[18]

According to documents published in August 2017, Pine Gap is used as a ground station for spy satellites on two secret missions:[6]

  • Mission 7600 with 2 geosynchronous satellites to cover Eurasia and Africa
  • Mission 8300 with 4 geosynchronous satellites that covered the former Soviet Union, China, South Asia, East Asia, the Middle East, Eastern Europe, and countries on the Atlantic Ocean


  • On 11 November 1983, Aboriginal women led 700 women to the Pine Gap gates where they fell silent for 11 minutes to mark Remembrance Day and the arrival of Pershing II missiles at Greenham Common in Britain.[dubious ] This was the beginning of a two-week, women-only peace camp, organised under the auspices of "Women For Survival". The gathering was non-violent and several women trespassed onto the military base and on one day 111[19] were arrested and gave their names as Karen Silkwood, an American nuclear worker who died after campaigning for nuclear safety. There were allegations of police brutality and a Human Rights Commission inquiry ensued.[20]
  • In December 2005 six members of the Christians Against All Terrorism group staged a protest outside Pine Gap. Four of them later broke into the facility and were arrested. Their trial began on 3 October 2006 and was the first time that Australia's Defence (Special Undertakings) Act 1952 was used.[21] The Pine Gap Four cross-appealed to have their convictions quashed. In February 2008 the four members successfully appealed their convictions and were acquitted.[22]

In popular culture[edit]

Peter "Turbo" Teatoff is seen delivering heavy machinery to JDFPG in season 4's 11th episode of series Outback Truckers.

Pine Gap is featured in the 2018 Australian television series Pine Gap of the same name. The series is a political thriller, portraying the lives of the members of the joint American–Australian intelligence team.

In The Secret History of Twin Peaks by Mark Frost, President Richard Nixon claims that Pine Gap is actually the site of an underground facility constructed by extraterrestrials.
