2017 What does the US Pine Gap spy base do? > .
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. 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.
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. Central Australia was chosen because it was too remote for spy ships passing in international waters to intercept the signal. The facility has become a key part of the local economy.
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. 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.
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:
- telemetry from advanced weapons development, such as ballistic missiles, used for arms control verification;
- signals from anti-missile and anti-aircraft radars;
- transmissions intended for communications satellites; and
- microwave emissions, such as long-distance telephone calls.
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.
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.
The Menwith Hill Station (MHS) in the UK is operated by the NSA and also serves as ground station for these satellite missions.
One of Pine Gap's primary functions is to locate radio signals in the Eastern Hemisphere, with the collected information fed into the US drone program. 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.
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. 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.
According to documents published in August 2017, Pine Gap is used as a ground station for spy satellites on two secret missions:
- 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
Under the 1959 Antarctic treaty, to which Xina is [a follow the rules only when it suits them] party, activities on the continent are restricted to “peaceful purposes”. Military personnel are allowed to conduct scientific research but analysts, including Blaxland, believe that information can also assist intelligence operations.
