    • Hypersonic Weapons – Australia’s Deterrent Future? – Cathy Moloney

      The 2020 Defence Strategic Update establishes a new policy framework on the foundation of the key principles: ‘shape, deter, respond’, and includes consideration of several capabilities as a means to achieve its strategic outcomes. Dr Moloney considers the meaning of deterrence and the role that hypersonic weapons may play in the implementation of a deterrence strategy for Australia. Our region is in the midst of the most consequential strategic realignment since the Second World War, and trends including military modernisation, technological disruption and the risk of state-on-state conflict are further complicating our nation’s strategic circumstances. The Australian Government, led by Prime Minister Scott Morrison recently released its 2020 Defence Strategic Update (2020 DSU) stating that the Indo-Pacific is the centre of an increasingly contested, apprehensive and deteriorating environment particularly since the release of 2016 Defence White Paper. The Update describes the challenges of this emerging environment and provides a new strategic policy framework to ensure ‘Australia is able – and is understood as willing – to deploy military power to shape our environment, deter actions against our interests and, when required, respond with military force’; a more assertive strategy than Australia has ever adopted before. The Government, therefore, intends to take a greater responsibility for its own security and must seek capabilities that match this ambition. Within the capability priorities set out in the Update are plans to acquire long-range missiles, with the potential inclusion of hypersonic weapons. The inclusion of such capability, specifically hypersonic weapons, will provide a new challenge to strategy and the way we think about and implement a deterrent strategy. There are strategic decisions that must be made before these weapons are a reality, not afterwards. The threat of hypersonic weapons increases the likelihood of compellence or coercion by risk as defined by Pape and Schelling due to their speed and manoeuvrability, which could alter the calculus of deterrence and the ability to attack, or hold at risk, high-value targets. The integration of the offensive use of hypersonic weapons capability into operational doctrine, for example, can create serious escalatory dynamics. This will be true for the Indo-Pacific, considering the major actors stationed in the region have programs and capabilities under development; possibly adding to the great power conflict and an ensuing arms race. Advances in hypersonic technology and the future deployment of such weapons across the region will have a large and possibly irreversible impact on Australia, and far-reaching consequences for the international system, state behaviour, escalatory dynamics, and the distribution of state power. To put the challenges Australia faces in context, we must grasp the principles of deterrence and how emerging hypersonic technology could change our comprehension of an Australian deterrence strategy. Deterrence is about the role of threats in global affairs and especially the threat of the use of force. In short, a relatively simple idea; convince your adversary that the costs of attacking you will outweigh any potential gains. There are two common assumptions of how this can be done, denial and punishment. The former tends toward control, although it has elements of coercion; and describes a threat that controls the situation effectively enough that it denies the adversary strategic options to achieve its military and political goals through aggression. The latter requires pure coercion where the adversary is not denied choice but incentivised to only choose a certain option or outcome – or impose unacceptable costs to an adversary in response to unwanted actions. There are, of course, costs to be considered in creating these conditions no matter what strategy is chosen; but there must be no reason for the adversary to doubt that threats could not be realised. If Australia is to develop a strategic deterrence posture, it must consider whether it wishes to pursue a strategy of denial or punishment and then what capability will deliver the most credible threat. Having a nuclear deterrent threat is generally considered a more credible capability because of the magnitude of the weapon. This is not an option for Australia considering its long-held policy on the non-proliferation of nuclear weapons. A conventional warhead on a ballistic missile needs to be exceptionally accurate to be credible, as the destructive capabilities will be less than that of a nuclear warhead. Thus, a conventional hypersonic weapon could be the next best thing to a nuclear deterrent: fast, accurate and relatively ‘clean’. Hypersonic development is not new, but it is crucial. Why? Because these weapons are primarily designed to breach existing or forthcoming missile defence systems that currently ensure the ability to deter advances from adversaries. In addition to being able to reach speeds faster than Mach 5 hypersonics can manoeuvre. Unlike ballistic missiles, which follow a stable trajectory that allows for missile detection systems to estimate the missile’s destination, hypersonics that can manoeuvre at hyper-speed pose a new danger. Two systems of interest with this capability are hypersonic glide vehicles and hypersonic cruise missiles. The former is a high-velocity booster, where the missile separates and uses momentum in the upper atmosphere before zeroing in on its target. The latter utilises a SCRAMJET propulsion system to reach its target. Russia, China, and the United States all have hypersonic development programs. (The US has declared the Global Precision Strike Missile program is only for conventional use.) Russia is at the forefront of fielding this capability, having tested its Avangard glide vehicle in December 2019. Further tests were conducted near Crimea on 9 January 2020, when Russia practised the launch of the hypersonic air-launched ballistic missile Kinzhal from two MiG-31K fighters. Both are now considered ‘in service’ and thus deployable capability for the Russian military. The agility and manoeuvrability of hypersonic weapons make them an ideal candidate to support modern military coercive strategy and tactics. For example, a surprise, the fast-conventional attack still allows for an operation to progress (i.e., the adversary is not annihilated) and coercive tactics can still be used towards the adversary to change their behaviour. This uncertainty is useful as part of a strategy of deterrence by denial. However, this raises the level of risk, and therefore, the question becomes is Australia ready for the possibility of this type of dynamic within our region? It is all well and good for Australia to focus on the acquisition of long-range missiles and the potential development of hypersonic weapons, but the emergence of this technology will remain a challenge for strategic thinkers and policymakers and for the way we think about deterrence. This technology demands that we reconsider our approach to deterrence and defence posture. In the twenty-first century, the doctrine of deterrence has been reinvigorated due to the rising tensions reappearing among great powers; the continuing threat of terrorism; and the changing character of war to include hybrid, asymmetrical, cyber and information warfare. The recent successful testing of Russian hypersonic missiles means that this is not an abstract conversation to have on a theoretical or academic level. Nor is this just a concern or an idea raised in the Prime Minister’s 2020 Defence Strategic Update. If this capability is built under the funding boost announced then Australian hypersonic and deterrence strategy is not a theory anymore but a real threat that would be operationalised to defend Australian interests—or used as a coercive tool to change great power politics in our region.

    • Vale Air Marshal David Evans AC, DSO, AFC (Ret'd)

      On behalf of the Board of the Williams Foundation, it saddens me to have to write to our members on the passing of one of Australia's most decorated Air Force officers, Air Marshal David Evans AC, DSO, AFC (Ret'd). As many of you are aware, Air Marshal Evans was a great supporter of the Foundation and a regular attendee to our events. I had a deep respect for him both professionally and personally and he will be missed greatly. Air Marshal Evans' career in the Air Force was remarkable.  Most notably, he served in World War II, as a member of the Australian contingent operating transports in the Berlin Airlift, and in the Vietnam War. He remained active following his RAAF career in Defence, academia, industry and politics. His autobiography,Down to Earth, was published in 2011 and is a fascinating read.  His life and many achievements are probably best highlighted on his David Evans (RAAF Officer)Wikipedia page, which I encourage you to read. Air Marshal Evans' celebration of his life will be held today 15 September 2020 at 1.30 pm and will be live steamed on the following link vimeo.com/455996382.  The legacy.com guest book is also available for signing. Our thoughts are with his family. Best regards, Geoff Brown AO Chair

    • #ADFRAS2040 – Summary

      A short article to link readers to all of the posts submitted in response to ADF Robotics and Autonomous Systems 2040 Call for Submissions. Over the past three months, the teams at Grounded Curiosity, The Central Blue and The Forge have been publishing posts that responded to the Force Exploration Branch’s call for submissions on the topic of Robotics and Autonomous Systems (RAS) in 2040. These submissions will be considered by the working groups that will iterate the Joint RAS Strategy on behalf of VCDF. This article summarises some critical themes across submissions to all three military blog platforms. For the purpose of this summary, ranks and titles have been removed – however, author biographies can be found with each linked article. Gary Waters and Patrick Bigland advocated for successful integration of autonomous systems, including those in virtual environments. Their focus in collaborative autonomy was the warfighter, while acknowledging some of the technical limitations of human control. Jacob Choi furthered the discussion on human-machine teaming, clarifying that robots will no longer be mere tools for soldiers, but teammates. He elaborated that we can take cues from how war animals’ bond with human handlers to provide some feedforward input to the Joint RAS concept. Gareth Rice wrote about the imminent advent of the human-cyborg soldier, starting with the battlefield of the brain. Keirin Joyce clarified that swarming is yet to be fully realised, despite these future systems having ‘started their capability life cycle in the 2010s.’ His primer reinforced the idea of scaling with a challenge to ‘think bold for 2040,’ with Matthew Ader further arguing that automated systems will turn the battlefield into a lethal panopticon. Ader elaborated in a separate article that humanitarian organisations and advocacy groups should also use autonomous systems, such as self-organising swarms of driverless trucks, to serve non-combatants within conflict-affected environments. Zac Rogers raised points for and against Uberisation in the business of war, with a potential model for the Australian Civilian Cyber Corps. Emily Delfina discussed why human control is necessary in autonomous weapons systems (AWS) from a legal, ethical and operational perspective, and the subsequent implications for Artificial Intelligence (AI) and machine learning (ML). Paul Grant and Nick Alexander argued that health is ‘no longer a mere enabler’, as the advent of autonomous health agents allows for greater opportunities to exploit, and vulnerabilities susceptible to adversary attack. Their ‘Warfighting health effect in 2040’ submission offered a vivid narrative into what autonomous medical evacuation, security for casualty evacuation, an airborne hospital platform, medical resupply and telehealth support will look like in 2040, threaded together across four vignettes. Jacob Simpson drew attention to the double-edged sword within AI concerning command and control (C2), and intelligence, surveillance, and reconnaissance (ISR). Simpson argued that by developing a counter-AI strategy, the ADF could sever an adversary’s trust in their AI-dependent C2 and ISR systems, thereby degrading their decision-making process and improving the ADF’s ability to achieve decision superiority. Kristi Adams highlighted the ethical and operational challenges that advances in biometric identification present to Australia. The relationship between biometrics and security has progressed rapidly from fingerprints, through facial recognition, to include heartbeat identification. AI-enabled, non-cooperative biometric collection and identification promises enhanced security but potentially at the risk of privacy. Nate Streher provided a naval perspective analysing how the action-reaction balance will continue to define technological development in the military. Mine countermeasures (MCM) have been at the forefront of RAS adoption, and this will unlikely change in the future, but, as Streher highlighted, for the all benefits that RAS provide MCM teams, there will continue to be vulnerabilities that can be exploited by a tech-savvy adversary. These submissions represent a wide selection of voices with diverse experiences in uniform and academia. Authors have written to provide their expertise in their respective fields, and in doing so, have supported the Joint RAS Strategy’s consultation process. The Central Blue, Grounded Curiosity and The Forge thank all the contributors for their submissions on behalf of Force Exploration Branch.
