These domains and areas are being weaponized for strategic purposes, as adversaries target cross-domain North Atlantic Treaty Organization (NATO) interests with the intent of weakening the Western security architecture and fragmenting alliance cohesion. The Trump administration must work closely with NATO allies to confront the many challenges that face them.

Strategic challenges, such as the Arctic, deep sea, and space, and the threats they pose require improved joint military readiness, enhanced deterrence by denial capabilities, and improved intelligence, surveillance, and reconnaissance.

“Over the last 15 years,” writes Scott Savits, “the Arctic has become a renewed theatre of military competition…. [T]op Russian officials have referred to the Arctic as Russia’s ‘Mecca,’ and a large fraction of Russia’s economy is based on Arctic fossil fuels and minerals.” Frustrating Russian efforts to gain a strategic advantage in the Arctic is of paramount importance to NATO’s deterrence mission.

Russia gaining an advantage in the Arctic will enhance its ability to establish escalation dominance against NATO in the event of a conflict with the alliance. Deterring Russia from broadening the scope of conflict, by threatening NATO’s vital interests in the Arctic, remains critical in dissuading other adversaries, such as China, from seeking to gain similar advantage.

With China developing and deploying new detection technologies in anti-submarine warfare, American nuclear submarine capabilities are becoming increasingly vulnerable to detection and targeting. China’s “Death Star” satellite claims to possess detection capabilities that renders the ocean transparent for up to 500 meters beneath the surface, putting American submarines at risk.

In the space domain, it is estimated that loss of access to space would come at a cost of roughly One billion pounds per day to the British economy. The reported deployment of Russian anti-satellite weapons systems (ASAT) in space are clearly coercive moves designed to threaten NATO’s space assets.

Russia’s weaponization of space is especially concerning as NATO depends on space to conduct an array of operations across the spectrum of deterrence and defence. Most notably, NATO airpower relies on space-based and space-dependent systems to fulfil a series of critical security functions. Leveraging robust deterrence capabilities in orbit, through targeting Russian and Chinese space-based military and non-military assets, is critical to securing NATO’s vital interests in space.

Beyond seeking strategic advantage, China is also expanding and modernising its nuclear arsenal at an unprecedented rate since the end of the Cold War. The Pentagon forecasts that China will be a nuclear peer of the United States by 2035. The latest figures published by the Federation of American Scientists show that China now possesses at least 500 operationally deployed nuclear weapons—up 43 percent from 2020.

Russian President Vladimir Putin continues to undermine international norms by persisting in threats to use battlefield nuclear weapons in Ukraine. Russia also deploys dual-use satellite technologies in space, capable of carrying nuclear warheads into orbit, in direct contravention of long-standing international treaties such as the Outer Space Treaty (1967), which prohibits the weaponization and nuclearization of space.

Meanwhile, Iran, a latent nuclear state, coerces the West by threatening the weaponization of its nuclear program. Iran also infiltrated the West by creating extremist networks through community centers, laundering money in major European and American cities that is used by criminal gangs to plot and execute terrorist attacks.

Proxies supported by Iran, such as Hamas and Hezbollah, can also launch increasingly devastating attacks. Furthermore, attacks like October 7, 2024, or September 11, 2001, do not warrant nuclear retaliation. A nuclear response to a terrorist attack, depending on the attack, is likely a disproportionate response.

China and Russia also engage in subversive activities within the cyber domain, sowing discord by using disinformation, intellectual property theft, and malign interference to destabilize NATO member states. Cyberattacks on critical national infrastructure can also inflict severe levels of damage. The appropriateness of cross-domain responses is yet to be decided.

The cyber attacks against Estonia in 2007, which lasted for 22 days, did not result in the triggering of NATO’s Article 5 collective defense clause. Yet, it was an attack on a NATO member state. The character of the attack complicated the process by which a viable and appropriate retaliatory response could be devised. In a multidomain threat landscape, hostile state actors conducting their operations in the grey zone can claim plausible deniability.

China, Iran, Russia, and North Korea also hold joint exercises, share intelligence, exchange military capabilities, and share a diplomatic and political kinship. This axis of Western adversaries shares the same geopolitical and economic objectives. They seek to replace the international rules-based order and establish alternative institutional frameworks to global order that undermine concepts such as democracy, human rights, rule of law, and national sovereignty.

Militarily, nowhere is this more apparent than in Russia, where Iranian drones and North Korean soldiers were provided to aid Putin’s war in Ukraine. Politically, emerging international blocs such as the BRICS demonstrate the extent to which countries like China and Russia are gaining traction in driving alternatives to the current order.

“As hybrid threats evolve to encompass the whole of digital and networked societies,” wrote Sean Monaghan, “so too will the capabilities required to deter them. A more complex threat environment will make predicting attacks and vulnerabilities more difficult, so nations may rely more on resilience.”

Hence, for deterrence to be effective today, credibility must incorporate more than hard power capabilities. Red lines must be communicated effectively across different channels. Resolve must be demonstrated through a force posture that includes a willingness to establish escalation dominance in a crisis scenario. The art of deterrence is also about determining and holding at risk what an adversary values.

As the outgoing US Secretary of Defence General (Ret.) Lloyd Austin said in 2022, cross-domain deterrence “is the right mix of technology, operational concepts, and capabilities—all woven together and networked in a way that is credible, flexible and so formidable that it will give any adversary pause…. [It is] multidomain, spans numerous geographic areas of responsibility, is united with allies and partners, and is fortified by all instruments of national power.”

Ultimately, deterrence is about credibly threatening to impose unacceptable costs, by denial or punishment, on a would-be aggressor. Those costs must convince the would-be aggressor that they outweigh any potential gains made.

Therefore, it is imperative for the US and NATO to increase cross-domain capabilities to match those of adversaries. Adopting a combination of different violent and non-violent means, to conduct deterrence credibly across multiple domains and at various levels of intensity, will enhance NATO’s ability to secure its vital interests in an increasingly volatile era of global strategic competition.

Deterrence and NATO’s Emerging Security Environment was originally published on Global Security Review.

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.

In planning to strengthen space defense capabilities, the French military procurement agency, Directorate General of the Armament (DGA) focuses on surveillance, security, and cooperation. France aims to have a full space defense capability by 2030, built on military space capabilities such as Earth observation, communications, positioning, and navigation. The country is also expanding its space situational awareness capability to monitor, classify, and better understand space activities and threats.

France unveiled Toutatis, a new space surveillance program to protect low-Earth orbit assets, focusing on satellite detection, characterization, and targeting. Toutatis works with two satellites. A “spotter” cubesat detects targets and a smaller target satellite—developed by French start-up U-space in partnership with defense industry major MBDA.

France also works on geosynchronous orbit surveillance through the Yoda program of small satellites with cameras to monitor space threats. The annual military space exercise, AsterX, highlights the need for enhanced situational awareness in low-Earth orbit. Within two years, the Toutatis program will test capabilities with planned launches of maneuverable satellites.

Rather than kinetic weapons against weaponized space assets, France deploys non-destructive measures like dazzling adversaries with lasers to neutralize threats—without creating debris. The country also seeks to balance autonomy with international cooperation. For example, an envoy from Ukraine recently discussed space defense in Paris. Pawan Kumar, Director of the Indian Defense Space Agency, recently provided the French space command with an update on military space cooperation between the two countries.

The French view is that enhanced situational awareness in space, through programs like Toutatis, is a cornerstone of its space defense strategies. Nations should prioritize investments in monitoring technology to observe potential threats and signal their deterrence capabilities.

France’s focus on space start-ups indicates a shift towards commercial and civilian involvement in space security. A timely joint-announcement made by two rising space ventures, Cailabs and Unseenlabs, revealed they successfully tested space laser transmission for satellite downlink in a world first. While Cailabs supplied the optical ground station, Unseenlabs deployed a low-Earth orbit nano-satellite with a laser payload. The pair established a stable link for several minutes. France’s Ministry of Armed Forces called the successful test a world first. It was a first for the commercial sector, but a few other experiments remain confined to American government attempts.

The French Defense Innovation Agency funded the test with €5.5 million ($6.1 million). The Cailabs/Unseenlabs system will be integrated on France’s future military satellites. Laser technology is hard to intercept or hack, compared with radio antennas.

Such a capability would be useful for expanding battlefield data transmissions. France’s optical communications satellite project, dubbed Keraunos (thunderbolt in Greek), helps mitigate the effects of atmospheric turbulence, making space-Earth liaisons handy on mobile, land-based, naval, and airborne platforms.

The European Space Agency Director, General Josef Aschbacher, rightly noted that a gap in space spending between Europe and the United States (a ratio of 1 to 6) is complicated further by spending in Europe that is spread among a wider range of national space agencies. Streamlining European defense and space governance is thornier than in the US since it involves structural reforms on technological gaps, fragmented capital markets, and strategic spending.

A rather disappointing report on European competitiveness by Mario Draghi, former Italian Prime Minister and president of the European Central Bank, generated immediate push-back from Ludwig Moeller, director of the European Space Policy Institute (ESPI). ESPI methodically reviewed the Draghi Report’s shortcomings when it came to European Defense and Space. ESPI suggested the report lacked an impulse for the needed market reforms.

As stated by Eva Portier, space deputy in France’s military procurement agency, Directorate General of the Armament (DGA), “Access to space is an essential element of our national sovereignty, our capacity to use space to launch our satellites and conduct operations.” While greater Europe is struggling to fundamentally unite in its efforts to counter future malicious space efforts by China and Russia, France is stepping forward in a more limited way. It is not lost on observers that French satellite names harken to a past where France needed protection. For example, Toutatis, discussed above, was a divinity once worshipped in ancient Gaul and Britain, and was considered a protector of Gallic and Celtic tribes. The annual military space exercise, AsterX, led by the French Air and Space Force and involving 15 partners countries, is a wink to Asterix and Obelix, leading characters of a comic book series describing the adventures of a small village resisting the Roman invaders. Legend has it the Gauls feared only “that the sky would fall on their head.”

French efforts are moving in the right direction, but unless Europe reforms and consolidates space defense efforts across the continent, Europe will be unprepared when a crisis occurs. Major space reforms take time. Thus, it is important those reforms begin now. France simply cannot accomplish what is needed on its own.
