The perception of adversaries that western democracies are increasingly dependent on space for joint and integrated military operations gives them an incentive to threaten access to the assets that enable this capability prior to beginning of a conflict. The United States and its allies, including Australia, are now responding to this changing strategic dynamic, with a much greater focus on the challenges of undertaking space control as an important new task, along with the potential opportunities of establishing dedicated space forces.

The Policy Path to Space Control

In 2020, the then Morrison-led Coalition government sought for the Australian Defence Force (ADF) to play a more ambitious role in space. The release of the 2020 Defence Strategic Update and the accompanying Force Structure Plan represented the first significant formal policy recognition of the importance of space control and the importance of space as an operational domain. The 2020 Force Structure Plan stated that:

Defence will need capabilities that directly contribute to war fighting outcomes in the space domain using terrestrial and/or space-based systems. The Government’s plans include the development of options to enhance ADF space control through capabilities to counter emerging space threats to Australia’s free use of the space domain and that assure our continued access to space-based intelligence, surveillance and reconnaissance.

It also aligned with the establishment of the Australian Space Agency in 2018 and the rapid growth of an Australian commercial space sector. This marked a truly fundamental shift from Australia’s previous approach of passive dependency on foreign states and commercial providers for space capabilities. Australia sought to become an active participant in a rapidly growing global space market, but also recognized that space access must be assured and protected in a contested and congested space domain.

The establishment of Australia’s Space Command (known initially as Defence Space Command) on January 18, 2022, also saw the release of the Defence Space Strategy which lists space control capabilities as a key objective towards “enhancing Defence’s space capability to assure joint force access in a congested, contested and competitive space environment.” The Space Command document states that “Defence will continue to identify space control gaps and opportunities to develop a credible Space Control capability, and space capability developers will actively seek to improve resilience of the space capabilities.” That would align with the decision by the following Albanese Labor government.

The Albanese government, which came to power in May 2022, largely sustained the previous coalition government’s approach to the ADF’s role in space. The 2023 Defence Strategic Review (DSR) sought to highlight the importance of the space domain, “re-posturing” Space Command into Joint Capabilities Group. The subsequent 2024 National Defence Strategy (NDS) and Integrated Investment Program (IIP) lifted planned government investment for the ADF in the space domain from about $7 billion (Australian dollars) under the previous Morrison-led coalition government to between $9 billion and $12 billion, though the vast bulk of this extra funding would not appear until late in the current decade. On space control, the Albanese government largely followed the lead of the previous Morrison liberal-national coalition, with the 2024 IIP stating planned spending will include “measures to enhance Defence’s space control capability to deny attempts to interfere with, or attack, Australia’s use of the space domain. These will help ensure the ADF is able to continue using the space capabilities it needs to support its operations.”

Capability Options for ADF Space Control

If Australia is to acquire a space control capability, it is certain to be a
“soft kill” system that disables or denies rather than physically destroys a target. The Albanese government signed a ban on destructive testing of direct-ascent ASAT systems on October 27, 2022, and any acquisition of a “kinetic kill direct-ascent ASAT would violate such a ban.” A kinetic kill ASAT capability is not consistent with Australia’s policy of sustainable use of space.

In 2021 the Morrison government announced a new defence project (DEF-9358) that would explore options for a ground-based space electronic warfare capability. Such an approach would be consistent with a preference for reversible or scalable effects that disable or deny rather than destroy.

Space-based “co-orbital” space control could conceivably include space electronic warfare technologies such as on-orbit jamming or even high-power microwave weapons for electronic attack in orbit. It is also conceivable that a ground-based electro-optical laser dazzling capability could be considered, with Australian commercial space companies demonstrating capability expertise in such a system. Finally, ground-based cyber capabilities could be exploited in space control operations against both satellites in orbit and ground facilities undertaking satellite telemetry, tracking, and control (TT&C).

Such soft-kill defensive, and potentially offensive, space control capabilities would contribute to assuring ADF space access by denying an adversary the ability to attack critical space support capabilities, such as ADF satellites for communications and intelligence, surveillance, and reconnaissance. This is consistent with the military strategy of deterrence by denial as laid out in the 2024 NDS. Other measures could be taken that include hardening key space support capabilities and potentially “silent spares” deployed in orbit.

To significantly strengthen ADF space resilience, the opportunity for the ADF to exploit emerging Australian commercial space launch capabilities is important. Embracing space lift as a means to assure sovereign space access makes eminent sense, given Australia’s geographic advantages for launch. By developing a responsive sovereign launch capability that can deliver small satellites into orbit, Australia can augment space support for the ADF and its allies in a crisis, or, if necessary, reconstitute lost capability in the aftermath of a counterspace attack.

Next Steps

Looking forward, the 2024 NDS established a biennial defence policy process, and the 2026 NDS and IIP represent the next best opportunity for Defence to more clearly conceptualize its approach to space control. Doctrinal documents within Space Command already suggest a role for space control, but greater detail is needed. Most importantly, there needs to be a public and unclassified policy explaining how the ADF will undertake this important task alongside allies and partners. Space control, like space domain awareness, represents an opportunity for the ADF to undertake a next step in its use of the space domain, beyond simply capability assurance and satellite communications, which was the perceived role of space in the 2023 DSR. In a contested space domain, Australia must burden share to a much greater degree in orbit and in acquiring the means to undertake space control tasks. This represents an important next step towards that outcome.

The Case for Space Control: An Australian Perspective was originally published on Global Security Review.

They continue similar priorities and themes to the previous coalition government’s 2020 Defence Strategic Update and Force Structure Plan on the space domain. As with those documents, the 2024 NDS and IIP highlight the importance of space as a critical enabler for terrestrial military operations and an operational domain in a multi-domain approach to a strategy of deterrence by denial.

Furthermore, they identify three broad capability areas for further development.  These include (1) the provision of space support, notably through satellite communications to be provided by Australian-owned satellites through project JP9102 in geosynchronous orbit; (2) the establishment of enhanced space domain awareness, with the establishment of a Deep Space Advanced Radar Capability (DARC) at Exmouth in Western Australia—part of a global network of three such sensors—in collaboration with the US and UK; and (3) the development of space control capabilities.

This last aspect of the NDS and IIP opens some intriguing possibilities for future development that could be announced in subsequent policy documents, with the next NDS and IIP due in 2026. It also raises the possibility that space could start to play a larger role as a priority area in AUKUS Pillar 2. Already, the agreement to establish DARC is seen as part of AUKUS and will extend Australia’s ability to undertake space domain awareness out to geosynchronous orbit (GEO) at 36,500 kilometers. That complements the existing C-Band radar and space surveillance telescope already located at Exmouth and will dramatically enhance the ability of Australia to undertake space surveillance under Operation Dyurra. This is an essential requirement for Australia to undertake the space control mission, so it would make sense to bring this role into AUKUS Pillar 2 as well and see the two missions as integrated.

Just how Australia will undertake space control needs further clarification. There is only the following paragraph in the IIP, which states that space control will include “measures to enhance Defence’s space control capability to deny attempts to interfere with, or attack, Australia’s use of the space domain. These will help ensure the ADF is able to continue using the space capabilities it needs to support its operations.”

Australia has signed the ban on undertaking destructive testing of direct-ascent anti-satellite (ASAT) weapons as part of steps to promote responsible action in space, and it is extremely unlikely that Australia would pursue destructive “kinetic kill”’ ASATs, either direct-ascent or co-orbital in design. Exactly what Australia could pursue in terms of space control is open to speculation at this stage. Defence has undertaken work toward a space-electronic warfare capability under Defence Project DEF 9358, and this would be consistent with the 2024 IIP’s stated approach to space control, as well as the 2020 Force Structure Plan.

A “soft kill” capability, which is either ground-based or co-orbital, that could deliver scalable and reversible effects without creating space debris would contribute directly to the need for space control in a manner that is also consistent with Australian approaches to responsible actions in space. In the same way, other non-kinetic approaches—directed-energy or cyber—might open up opportunities for Australia to develop space control in the future.

The 2022 Defence Space Strategy, released by Defence Space Command, makes clear the importance of assured access to space. This can be achieved in part through resilience of space support, including through defending satellites on-orbit via space control. But it also can be strengthened through enhancing sovereign launch capability. It is in this area where the 2024 NDS and IIP misses a valuable opportunity to integrate the space needs of defense with the growing commercial space sector.

There is no mention whatsoever of Australia’s vibrant commercial space sector in the 2024 NDS and IIP. It is almost as if the view from Defence is that this growing sector does not exist. Yet, Australia’s space sector is fast emerging as the basis for an end-to-end ecosystem, comprising not only the ground segment, but also satellite design and manufacturing through to sovereign launch capabilities.

Indeed, Australia is truly blessed in geographic terms for sovereign launch, with launch sites in the north located close to the equator to take full advantage of Earth’s rotational energy for cheaper cost per kilogram into equatorial low-earth orbit, and launch sites along the south of the continent that are well placed to access polar and sun synchronous orbits. Australia’s launch geography is a key factor prompting the signing of a Technology Safeguards Agreement with the United States on launches and returns.

Defence missed this opportunity to strengthen space resilience through supporting sovereign launch of small satellites that could complement large satellites in GEO, such as those envisaged for JP9102 with proliferated LEO (pLEO) constellations of small satellites for satellite communications and earth observation, to support both civil and defense needs. It missed the clear benefits of sovereign launch to reinforce assured access to space, through rapid augmentation of existing space capabilities in a crisis—or reconstitution of those capabilities in the event of an adversary employing counterspace capabilities against Australian satellites. It missed the opportunity for Australia to take a new step forward to do more to burden share in orbit with allies and strengthen the resilience of space support in the face of counterspace threats from China and Russia.

As the NDS and IIP are biennial documents, the opportunity is still there for Defence to embrace a bolder vision for Australia in space in the next release in 2026, whilst government more fully supports the growth of the commercial space sector. The question is whether Defence and the government will have the vision and determination to do something new. They have begun to think in these terms, given their support for developing space control capabilities, but they can do so much more.
