Mobilising Space for Army
Space Assets, Space Data, and Space Workforce on the Ground
Modern militaries have developed a high dependency on space-based services for all operations during peacetime, times of tension or competition, and times of conflict. Satellites are critical for providing a range of data and supporting technologies, many of which have little or no redundancy in terms of non-space-based alternatives. This observation encompasses the entire range of military activity: encrypted and classified communications, navigation, situational awareness, monitoring adversary movement, deploying precision-guided weapons, intelligence-gathering and meteorological data, and the ability for deployed soldiers to communicate with families at home across peace, competition and conflict. All of these needs are served by satellite capabilities, only parts of which are sovereign owned and operated. For Army, this high dependency has implications in the case of rapid mobilisation, both in terms of strengthening operations and in terms of vulnerabilities, both of which will be explored in this paper.
Mobilisation is defined in this paper according to Defence’s ‘Preparedness and Mobilisation’ doctrine, where mobilisation is described as a shift in the usual peacetime balance between civil and Defence needs, in favour of Defence needs at a time of crisis. These needs ‘may require greater capability and a more comprehensive national support base than is normally available to Defence’.[i] This situation necessitates taking capability away from the civil workforce, production and services. The extent of this shift towards Defence needs can occur along a spectrum. The doctrine describes the spectrum of mobilisation as ‘the process of transition between preparedness and the conduct of a specific operation’, comprising four stages.[ii] The first is ‘elective Defence mobilisation’. During this stage, operations may be launched without budget supplementation and so Defence’s financial reserves may need to be called upon. Examples of this are the range of small natural disaster response operations (bushfires, floods etc.) and peace operations. The second stage is ‘Partial Defence Mobilisation’. This stage of mobilisation requires budget supplementation and an increase in functional inputs to capability (FIC), as well as likely mobilisation of industry or national resources. Examples of this stage are the early part of Australia’s operations in East Timor and more recent operations in Iraq and Afghanistan. ‘Defence Mobilisation’ is the third stage and is much more intense than prior stages. It requires the preparation of all capabilities, a call out of Reserve forces, significant budget supplementation, and increases to FIC (an extension of capabilities may also be required). An example of this stage of mobilisation is the introduction of conscription to expand the Australian Defence Force (ADF) for Vietnam.
The fourth stage is known as ‘National Mobilisation’. It is the most extreme form of mobilisation and would lead to significant impositions on the general public. Also known historically as ‘total defence’ (such as was employed by the Australian Government during the Second World War), it entails full government control over the entire nation’s civil workforce and production. Peter Layton’s historical comparison of mobilisation efforts suggests that, while there was sufficient societal will for government to deliver a policy of total national mobilisation at the peak of the Second World War (in particular after the attacks in Darwin), it would be difficult to achieve similar levels of social commitment in today’s context. A modern government would therefore struggle to enforce total national mobilisation.[iii] However, as pointed out in one RAND study, total defence concepts remain a key frame of reference because they offer a way to ensure that not only are armed forces prepared to become actively engaged when the nation’s security requires it ‘but the entire nation is, that is, individuals, community/volunteer groups, local governments, businesses, key industries, and state and municipal governments’.[iv] The necessity of all these individual and collective parts of the nation being prepared to become actively engaged is especially true as Australia finds itself in a multi-polar or possibly ‘networked’ geopolitical reality, where civil society, academic experts, the private sector and other non-state actors are highly influential in shaping global strategic and political realities, and are all intertwined with Defence. As Layton puts it:
An Australian national mobilisation in a networked future would be whole-of-society by design, make use of market forces to allocate scare resources, and have governmental controls that encourage business and workforce participation through financial incentives.[v]
In the 2024 National Defence Strategy (NDS), the term ‘mobilisation’ does not appear, but the concept of ‘national defence’ shares striking similarities with the definition of mobilisation under the doctrine. In the NDS national defence is defined as ‘a coordinated, whole-of-government and whole-of-nation approach that harnesses all arms of national power to defend Australia and advance our interests’.[vi] A paper by the Asia-Pacific Development, Diplomacy and Defence Dialogue (AP4D) has identified how this ‘whole-of-nation’ approach has been echoed in many public policy statements by Prime Minister Albanese, Foreign Minister Wong, and Deputy Prime Minister and Minister for Defence Marles, and gives the following definition:
Whole-of-nation refers to coordination with tools beyond the immediate control of government. In international policy this involves the Australian Government engaging consistently and broadly with state and territory governments and with nongovernment actors such as business, the tertiary sector, NGOs, community and diaspora groups, media, sports and cultural organisations.[vii]
Certainly when it comes to high-tech threats, such as cyber and the loss of space-based services, the private sector specifically will need to be prepared to mobilise. This is particularly the case in regard to the first and second stages of mobilisation described in the doctrine. Indeed, Australia’s 2023–2030 Cyber Security Strategy includes civil, commercial and defence entities and organisations, not only because the private sector is vulnerable to cyber interferences but also because it may hold the key to contributing to Defence and other national cybersecurity needs.[viii] The extent to which cyber-threats and cybersecurity pervade people’s lives and impact Australia’s national wellbeing has led to an integrated approach under this strategy. Space-based services permeate Australia’s national security in similar ways, and a greater awareness is needed of space technologies as critical infrastructure: we all need to think about space, a little bit all of the time, in the same that way we think about cyber, a little bit all of the time. What this means for Army is the focus of this article.
As a starting point, it is important to understand that space systems comprise more than just ‘satellites’. Rather, space systems encompass four segments:
- The space segment, including satellites and spacecraft
- The ground segment, including satellite dishes and data processing or management
- The link segment, which is the communication link between a satellite and the ground station. All satellites need to send and receive data and instructions, and the majority of them do so by way of radio frequency (RF)
- The human segment, including operators, data processing experts, and users. This includes soldiers, sailors and aviators, as well as civilians. The majority of space systems today are ‘dual use’, providing the same service to military and civilian end users simultaneously. This has implications for targeting and grey zone operations designed to interfere with space systems because the impact on civilians must be taken into account under the laws of armed conflict.[ix]
In a scenario where Army is required to mobilise rapidly—whether in response to civil and natural disaster needs, national or regional security crisis, or conflict—space systems are an integral support to multiple aspects of Army’s needs. But currently Australia has no sovereign-owned satellites, and space services for military needs are purchased as data or as timeshare access to partner country owned satellites, or provided in return for access to Australian ground infrastructure and data management. Mobilisation of space technologies and a skilled space workforce will therefore be necessary to support Defence needs in times of competition, crisis or conflict.
This article will first consider how space-based technologies support Army and the ADF more generally. It will then discuss the context of mobilisation and resilience in our 21st century geopolitical context, including how space-based technologies fit into Australia’s integrated, focused armed forces under the new 2024 NDS. It will then identify how Army needs to think about mobilisation of (a) space-related assets, (b) space data and (c) people, who are the operators and users of space capabilities. To be clear, mobilisation of space-related assets includes the ground segment, such as major satellite dishes on Australian or foreign territory, which may not always comprise military assets. It may also include mobile ground stations, such as any vehicles which carry smaller satellite dishes for use during deployment, and small personal units like satphones or navigational equipment. Mobilisation of space data includes the ability to task satellite systems such that geospatial intelligence (GEOINT) data can be gathered, and assured access to secure communications and navigation can be provided. Given that Australia currently has no sovereign-owned space assets, the ADF is dependent on relationships with foreign government and commercial partners, which leaves Army vulnerable to loss of service or poor-quality data. And mobilisation of the people who are the operators and users includes Army personnel, Defence personnel broadly, contractors, and civilians in the private and research space sectors.
