“In the world of pragmatism, where deals must finally be cut, a treaty to ban nuclear weapons once and for all is urgently required … We must resuscitate, rejuvenate and exploit the tradition of international cooperation that has achieved bans on chemical and biological weapons, landmines, even dumdum bullets, but not yet on the world’s worst weapons of terror.”

– Dr Bill Williams

 

The International Campaign to Abolish Nuclear Weapons, known by its clever acronym, ICAN, was co-founded in Melbourne in 2006 by two Australian doctors, Tilman Ruff AM and the late Bill Williams. Over the following decade ICAN became a truly global campaign with more than 400 partner organisations in 95 countries.

 

In July 2017, in partnership with a group of progressive countries, ICAN succeeded in getting the United Nations to adopt a treaty banning nuclear weapons. Support was 122 votes to one; missing from the vote were the nuclear powers and their supporters including Australia, which did its best to derail the process. Later that year,  ICAN was awarded the Nobel Peace Prize for their efforts leading to the treaty and for drawing attention more broadly to the catastrophic humanitarian consequences of any use of nuclear weapons.

 

The treaty opened for signature at United Nations headquarters in New York on 20 September 2017 and will remain open indefinitely. Once 50 nations have ratified or acceded to it, it will enter into force. At the time of writing, 70 countries have signed, of whom 23 have ratified.  The latter include New Zealand.

 

The Australian government cites the US alliance and our commitment to the so-called ‘joint facilities’ as the key obstacle to our country getting on board. In this piece, which we publish on Hiroshima Day, RICHARD TANTER, an expert in Australian defence policy, points to a way through.

 

 

 

Since failing to prevent the adoption of the nuclear ban treaty, the Australian government has shifted ground on its opposition  as the treaty moves towards entry into force. In a remarkable display of arrogance and intellectual over-reach the government now asserts that, even if Australia wanted to join the Treaty on the Prohibition of Nuclear Weapons, it is simply incompatible with the continuation of the US alliance. We are, the government says, already in too deep to pull out.

 

On May 31, 2018, Richard Sadlier, a DFAT assistant secretary told a Senate estimates hearing that joining the treaty would be ‘impossible’, because the nuclear elements of activities at the ‘joint facilities’ are now too densely interwoven with the non-nuclear elements that they cannot be separated.

 

The joint facilities – the Australia-located elements of the US globally distributed systems of nuclear command, control and intelligence – are, Sadlier argued, made up of ‘many separate interlocking structures, understandings, agreements and joint activities and facilities’ that are ‘incompatible with the treaty’, and that it is ‘impossible, not practical, for Australia to restrict roles under the alliance to non-nuclear missions.’

 

Sadlier did not feel a need to burden senators with any factual details about the undoubtedly complex situation at Pine Gap, North West Cape, or the numerous other ADF bases to which US forces have access and which may have some activities that support US nuclear planning and operations. No doubt, half a century of Australian nuclear cooperation with the United States will make analyzing and weighing the significance of the full range of nuclear-related activities at Australian bases a major research task. And as with many international treaties, lawyers are going to argue about ‘how much assistance is too much’ under the TPNW.

 

Pine Gap is the obvious test case.

 

Pine Gap is a US-constructed and US–paid-for intelligence facility outside Alice Springs operated by the US National Reconnaissance Office. More than 800 Australians and US men and women staff the facility, including units from all four branches of the US military.

 

A careful examination of precisely what Pine Gap does shows there is a viable pathway in the most important of its nuclear-related activities for Australia to become compliant with the TPNW without necessarily disrupting its alliance with the United States.

 

The US has for some time built technological alternatives to relying solely on Pine Gap for its most important nuclear-related operations.

 

Pine Gap’s multiple and complex intelligence activities can be very roughly characterised as providing ‘big ears’ and ‘big infrared eyes’. There are three distinct major space-related surveillance systems installed at Pine Gap, one of which has a critical role in US nuclear command, control and intelligence.

 

This is the Relay Ground Station (RGS) in Pine Gap’s western compound. The four main antennas of the RGS provide linkage to US early warning satellites which are together known in US military jargon as Overhead Persistent Infra-Red or OPIR, consisting of older Defense Support Program (DSP) satellites and the successor Space-Based Infra Red System (SBIRS) satellites. The infrared OPIR sensors detect the heat bloom of intercontinental and submarine-launched nuclear ballistic missiles launched against the US. Data from these sensors is downlinked to Pine Gap and sent automatically in real time to the system’s Mission Control Station at Buckley Air Force Base (AFB) in Colorado, US Strategic Command and the White House, as early warning of nuclear attack.

 

In the US, the same data stream flows on to the US Air Force’s Space Command, providing missile launch locations and anticipated trajectories for combined US and Japanese missile-defence systems. Today, these missile defence systems depend on ‘cueing’ from Pine Gap to have any chance of finding their targets in flight in space.

 

Each of these two functions of the Relay Ground Station – early warning, and missile defence – might be seen as defensive, and therefore stabilising. However, such a claim is misleading. Missile defence, when it is possessed by only one of two nuclear-armed enemies, is anything but defensive and stabilising. China correctly points out that US–Japanese missile defence, should it work as advertised, promises to make China’s ‘minimum means of retaliation’ deterrence force vulnerable to an attack by America’s 6000 or so nuclear weapons. This has led China to modernise its current 250 to 300 nuclear weapons in a classic action-reaction armament cycle.

 

Critically for compliance with the TPNW, the infrared satellites that provide early warning of an attack are also essential for US nuclear war fighting.  The same technology that detects the heat blooms of missile launches also indicates which known adversary nuclear missile sites are empty following firing, and which remain capable of firing. This is critical data for rapidly compiling the list of locations to target for a US retaliatory strike – so-called ‘re-targeting’. The base’s role in nuclear targeting undoubtedly contradicts the TPNW’s prohibition on assistance in the use or threat of use of nuclear weapons.

 

To comply with the TPNW, an Australian government would have to provide assurances that the Relay Ground Station’s OPIR systems could not and would not be used for nuclear planning or operations. The politically critical question is how this could be achieved without threatening US national security interests.

 

One approach to compliance could be for the Australian government to request, and the United States to accept, verifiable binding legal, organisational and technical limits on specific categories of the operations of the RGS – i.e. separating the defensive functions from nuclear war-fighting. Achieving agreement to such verification from the United States would be very difficult at any time, and highly implausible at present.

 

An alternative approach would be for an Australian government to require the closure of the Relay Ground Station and the removal of its systems from Pine Gap, leaving the rest of the base and its principal signals intelligence functions – and acknowledged US national security concerns – unaffected. This could occur over an agreed period of time – say, for argument’s sake, five years.

 

This is technically and strategically achievable without closing Pine Gap as a whole, and without throwing the alliance into crisis, for two good reasons.

 

Firstly, the OPIR Relay Ground Station is quite different in physical, personnel and technological character from the much larger signals intelligence part of the facility. The RGS is physically small and distinct, and is operated automatically and remotely by the Mission Control Station at Buckley AFB in Colorado. There are only a very small number of staff on site at the RGS – essentially for maintenance. Pine Gap does not process or retain any of the data downlinked from the satellites – it flows automatically to Buckley AFB by optical fibre and satellite communication.

 

Secondly, for decades the US has been acutely aware of the physical vulnerability of critical nuclear command and control facilities like Pine Gap to enemy attack, and has therefore built technological redundancy into the OPIR system. All of Pine Gap’s OPIR satellites have satellite-satellite crosslinks and communications links to US relay satellites. These enable the crucial warning data to be transmitted from one to another and then downlinked to the Mission Control Station on US soil without ever relying on the Pine Gap RGS.

 

More than a decade ago a senior Australian naval officer, Commander Tom Mueller, came to the same conclusion: ‘The facility is little more than a relay station that is known by the Americans as a “bent pipe”. This means that the data comes in from a satellite and is relayed automatically to the United States. No processing of missile launch data is done at Pine Gap. Moreover, the satellite feed goes to other ground stations, and also hops from satellite to satellite back to the United States. This level of redundancy means that Washington could close the SBIRS missile detection system at Pine Gap with no detriment to its NMD program.’

 

In addition, US OPIR satellites themselves can and do downlink directly to dispersed mobile ground terminals in the US, as well as to US combat commands around the world, such as South Korea. The RGS at Pine Gap – which is highly vulnerable to attack – provides redundant backup to both the cross-links and the mobile stations systems but is not in itself essential to the OPIR system’s survival.

 

By deterring a surprise first strike, reliable early warning of nuclear attack is a key element of nuclear deterrence. Even with the RGS closed, all the data critical for US early warning would still flow from the OPIR satellites to the Mission Control Station.

 

The Pine Gap Relay Ground Station could be closed, with appropriate notice of intent, without genuine disadvantage to US national security.  This would provide a technically and strategically feasible pathway past the most important obstacle posed by Pine Gap to Australia becoming compliant with the TPNW.

 

Of course, there are other activities both at Pine Gap (‘big ears’ or signals intelligence) and at other bases that do or could assist US nuclear weapons use. Some of these may turn out to be more obdurate to reform, and pose more difficult political decisions.

 

Yet while further research into the full range of these potentially prohibited activities is necessary, the RGS constitutes the principal and most direct form of assistance to US nuclear war fighting. An Australian government that was acting in good faith would be taking a huge step towards compliance with the prohibition on assistance to fighting a nuclear war by giving notice the US that the RGS is to be closed.

 

The government’s claim that Australian assistance to US nuclear weapons planning and operations is inseparable from non-nuclear alliance cooperation is incorrect, disingenuous, and arrogant in this most important and egregious case.

    Thanks for posting such an important article, by Professor Tanter.
    The issue of eliminating nuclear weapons, along with tackling climate change, are probably the two most significant issues facing humanity.
    The Australian Government must take all necessary steps to ensure that we are in a position to sign on to the ban treaty and join in solidarity with all the other countries who have ratified the UN ban treaty.
    Our futures and that of our children and grandchildren may depend on this.

    Australia’s alliance with the USA is costly to us in a myriad of ways.
    I believe we can be a peaceful and an independent nation, with a strong stance on peace and human rights. Instead of a nation beholden to the USA’s foreign policies and attempting to derail the Nuclear Ban Treaty. How shameful!
    We need to free ourselves from the colonisation of our imagination and build a better world.
    Prof Tanter offers some good and rare insights and dialogue, the sort that should be in parliamentary discourse.

    If Australia’s alliance with USA may prevent us from joining the nuclear test ban treaty then rather than discussing whether we can join the treaty, we should re-consider the importance of our alliance with USA.
    In 2021 Australia’s position in the world suggests we should consider the value of multilateral dependence, rather than being dependent on USA.

    Thanks to ASNews for publishing this most interesting piece of information and analysis by Richard Tanter.
    Timely reminder as on 9 aug, a remembrance day for the first two disastrous nuclear explosions on Hiroshima and Nagasaki 74 years ago, the Australian director of ICAN, Ms Gem Romuld will address the Alice Springs Peace Action Think Tank (ASPATT) and friends at a dinner to launch ICAN report “Choosing Humanity: Why Australia must join the Treaty on the Prohibition of Nuclear Weapons”.
    The question remains: where does Australia stand in this life threatening debate? Shall Scomo join the arms race or take the steps that our Kiwi cousins have already chosen?
