Allied Orbital Warfare Planning and the New Phase of Military Space Operations

Operation Olympic Defender

The May 12, 2026 Breaking Defense article, U.S., Close Allies Creating Joint‘Orbital Warfare’ Plan: SPACECOM Chief, reports that the United States and six close military space partners are developing a joint plan for future “orbital warfare” based on comments by U.S. Space Command Commander Gen. Stephen Whiting. The plan is being developed through Multinational Force Operation Olympic Defender, a military space coalition involving the United States, Australia, Canada, France, Germany, New Zealand, and the United Kingdom. Whiting said the participating nations expect to complete a collective concept of operations for defending orbital assets by the end of 2026.

The development marks an important shift in allied military space cooperation. Operation Olympic Defender has already served as a combined military planning structure, but the new concept of operations would move the partnership closer to practical coordination for protecting satellites, monitoring threats, synchronizing national capabilities, and preparing for conflict scenarios in orbit. U.S. Space Command states that the multinational force is designed to integrate military spacepower, enable joint and combined forces, deter aggression, and retain military advantage if deterrence fails.

The Meaning Of Orbital Warfare

“Orbital warfare” is no longer a fringe term in U.S. military space doctrine. The U.S. Space Force identifies orbital warfare, electromagnetic warfare, and cyberspace warfare as primary counterspace mission areas. In official Space Force framing, counterspace operations may include offensive and defensive actions intended to preserve space superiority and support the broader Joint Force.

In practical terms, orbital warfare refers to military operations involving satellites and other space systems in orbit. It can include defensive measures to protect satellites, actions to track and characterize suspicious spacecraft, maneuvering to preserve mission capability, and broader planning for how space systems may operate under threat. The public record does not disclose the detailed capabilities being integrated into the new allied plan, and the subject should be understood at the strategic and policy level rather than as a public description of operational tactics.

The term reflects a changing view of space. For decades, military space systems were often described mainly as support infrastructure for communications, navigation, missile warning, weather, intelligence, and targeting. The newer doctrine treats space as an active operational domain where friendly systems may need to maneuver, defend themselves, support military forces on Earth, and operate against hostile interference.

Operation Olympic Defender As The Allied Framework

Multinational Force Operation Olympic Defender began in 2013 under U.S. Strategic Command and has since expanded into a seven-nation military space effort. Its participating nations are Australia, Canada, France, Germany, New Zealand, the United Kingdom, and the United States. U.S. Space Command says the force formally achieved seven-nation membership and declared Initial Operating Capability in April 2025.

The coalition’s stated objectives include improving mission assurance, strengthening the resilience of space-based systems, synchronizing deterrence efforts, and reducing the spread of orbital debris. The group also developed collective concepts of operations for space domain awareness, a combined operational framework, national space inputs, communications processes, and a campaign plan as part of its Initial Operating Capability work.

The new orbital warfare plan would build on those earlier planning efforts. Whiting said the allied group is now working on how to integrate, synchronize, and deconflict the capabilities that each nation may bring to the defense of orbital assets. That language suggests a move from general cooperation toward practical operational planning among allied military space commands.

Why The Plan Matters

The new plan matters because modern military operations depend heavily on satellites. Space systems support command and control, secure communications, navigation, missile warning, intelligence collection, surveillance, reconnaissance, weather monitoring, and timing services. These functions are embedded not only in defense operations but also in civilian life, including banking, agriculture, aviation, logistics, communications, and emergency response.

The security environment has changed because potential adversaries have developed more ways to disrupt, degrade, or threaten satellites. The Secure World Foundation’s 2026 Global Counterspace Capabilities Report assesses counterspace capabilities across five categories: co-orbital systems, direct-ascent systems, electronic warfare, directed energy, and cyber. The same report notes continued counterspace development by 13 countries and states that non-destructive counterspace capabilities are being used in active military conflicts.

The Center for Strategic and International Studies described the normalization of space as a military warfighting domain as a major feature of the current security environment. CSIS also noted the rapid growth in space objects, reporting that the United States tracks roughly 50,000 objects, including more than 15,000 satellites, and warning that congestion, collision risk, and debris growth will increase without stronger space domain awareness and clearer norms.

Space Domain Awareness As The Foundation

The allied plan appears to rest heavily on space domain awareness, which means the ability to detect, track, identify, characterize, and understand objects and activity in space. Without space domain awareness, allied militaries cannot confidently determine whether a satellite is drifting, maneuvering normally, approaching another spacecraft, preparing for inspection, creating collision risk, or behaving in a potentially hostile way.

Operation Selene illustrates this foundation. U.S. Space Command reported in April 2026 that Operation Selene was a Canadian-led effort involving all seven Operation Olympic Defender nations. Whiting described it as the most focused combined space domain awareness operation to date and said it synchronized effects across eight command-and-control centers.

Whiting said Operation Selene involved a high-interest target on orbit and combined the seven nations’ space domain awareness capabilities to improve custody of that object. He also said the operation was successful enough to become a permanent operation for Multinational Force Operation Olympic Defender.

Rendezvous And Proximity Operations

The allied orbital warfare plan is also connected to prior rendezvous and proximity operations. These operations generally involve spacecraft operating near other space objects for purposes such as inspection, servicing, monitoring, characterization, or other mission needs. They can be legitimate and peaceful, but in a contested environment they also raise security concerns because close approach capability can be difficult to interpret.

Whiting indicated that the new planning effort builds on three rendezvous and proximity operations conducted over the prior 18 months with individual Operation Olympic Defender partner nations. U.S. Space Command also stated that it had executed three on-orbit operations under the Operation Olympic Defender framework with France and the United Kingdom since 2024.

This activity suggests that allied military space cooperation is becoming more operationally concrete. Earlier space cooperation often centered on data sharing, policy coordination, and awareness. The recent pattern involves combined operations, multinational command-and-control coordination, allied participation in space surveillance activity, and planning for future protect-and-defend missions.

The Role Of Canada And Other Allies

Canada’s leadership of Operation Selene is notable because it shows that the allied framework is not simply a U.S.-run activity with passive partners. Canada has invested in space surveillance, including a 2026 contract with MDA Space for ground-based optical capability under the Surveillance of Space 2 project. The Canadian government said the project will establish three remotely operated telescope sites in Alberta, Manitoba, and New Brunswick by 2028 and contribute data to allied networks.

Canada’s announcement explicitly linked the Surveillance of Space 2 project to the North American Aerospace Defense Command and Operation Olympic Defender. It also described Canada as a founding member of the coalition and tied the project to space domain awareness and protect-and-defend mission sets.

Australia, the United Kingdom, France, Germany, and New Zealand also bring different national space capabilities, policy priorities, and military requirements to the coalition. The central challenge for Operation Olympic Defender is not only whether each nation can contribute sensors or operational personnel, but whether the group can create shared rules, authorities, communications channels, and decision processes that work under time pressure.

Commercial Space As Part Of The Planning Environment

U.S. Space Command plans to continue Apollo Insight tabletop exercises with commercial industry on a quarterly basis in 2026. These exercises are separate from the allied orbital warfare concept of operations, but they are closely related because commercial companies now operate much of the infrastructure that modern military and civilian systems depend upon.

U.S. Space Command held its first Apollo Insight Commercial Integration tabletop exercise on March 23, 2026. The event included U.S. defense experts, government leaders, allied nations, and commercial mission partners, and it addressed a notional worst-case scenario involving weapons of mass destruction in space. The event was classified, but U.S. Space Command said discussions covered domain awareness, detection, characterization, and threats to U.S. and allied space superiority.

The command reported strong industry participation, including 62 companies and 175 people. Future 2026 Apollo Insight exercises were planned around orbital maneuver warfare, proliferated constellations across orbital regimes, and integrated missile defense.

The Nuclear Payload Scenario And The Outer Space Treaty

One of the most sensitive topics associated with the Apollo Insight exercise is the scenario of a possible nuclear payload on orbit. Whiting said such a future is one the United States does not want to see and that it would violate the Outer Space Treaty.

The Outer Space Treaty’s Article IV states that treaty parties shall not place in Earth orbit objects carrying nuclear weapons or other weapons of mass destruction, install such weapons on celestial bodies, or station such weapons in outer space in any other manner. The treaty also requires activities in outer space to be conducted in accordance with international law and with regard to international peace and security.

This legal background matters because allied orbital warfare planning must operate within international law, alliance commitments, and national policies. The policy challenge is to strengthen deterrence and defensive preparedness without creating avoidable escalation, undermining norms of responsible behavior, or normalizing destructive conduct that could damage the orbital environment for all users.

Dynamic Space Operations And Sustained Maneuver

Dynamic space operations and sustained space maneuver are also planned topics for future U.S. Space Command tabletop exercises. These concepts are important because traditional satellites often have limited maneuvering capacity and must conserve fuel over long mission lifetimes. In a contested domain, that constraint can limit the ability to reposition, avoid threats, inspect nearby objects, or maintain mission advantage.

U.S. Space Command discussed the requirement for sustained maneuver and dynamic space operations as early as 2023. The command described dynamic space operations platforms as systems that could help mitigate constraints in the space domain through capabilities such as on-orbit servicing or extended lifespans.

The strategic implication is that future military satellites may need to be more mobile, more serviceable, and less dependent on one-time fuel budgets than many legacy spacecraft. That could increase demand for propulsion, refueling, on-orbit logistics, servicing vehicles, advanced space situational awareness, autonomous operations, and resilient command-and-control networks.

Strategic Deterrence In Orbit

The allied orbital warfare plan is best understood as part of a deterrence strategy. Deterrence in space depends on convincing potential adversaries that attacks against allied space systems would be detected, attributed, resisted, and answered in a way that denies benefit. The goal is not only to prepare for conflict, but to reduce the likelihood that an adversary would believe a space attack could succeed at acceptable cost.

Multinational planning strengthens deterrence by making the target set more complicated for an adversary. A hostile actor considering action against a satellite may face not just one national command structure, but a network of allied sensors, operators, data-sharing arrangements, and response options. That integrated posture can make space aggression harder to hide and harder to exploit.

At the same time, deterrence in orbit is difficult. Attribution can be complex, spacecraft behavior can be ambiguous, and some forms of interference may be reversible or non-destructive. A satellite anomaly may result from natural causes, technical failure, accidental interference, or hostile action. This is why space domain awareness, shared operating pictures, and agreed procedures are central to the new allied planning effort.

Risks Of Escalation And Misinterpretation

Orbital warfare planning also creates risks. Close approaches, maneuvering demonstrations, bodyguard satellites, co-orbital systems, and counterspace preparations may be interpreted differently by different nations. A defensive move by one state may appear threatening to another, especially when capabilities are dual-use.

The Secure World Foundation has warned that the growth of counterspace capability and more aggressive military postures require open public debate because conflict in space could produce long-term negative effects for society, the economy, and the space environment. Even testing certain counterspace capabilities can create long-lasting risks if debris or interference affects other operators.

This is why responsible allied planning must balance readiness with restraint. Clearer norms, better communications, stronger attribution methods, and careful rules of engagement are all important for preventing a crisis from escalating because of uncertainty or miscalculation.

Industrial And Space Economy Implications

The new allied focus on orbital warfare has direct implications for the space economy. Space domain awareness providers, satellite operators, on-orbit servicing firms, propulsion companies, secure communications providers, cyber defense vendors, analytics firms, and mission software developers may see growing demand from defense customers. U.S. Space Command’s Apollo Insight exercise already indicates that commercial industry is being brought into classified planning environments to identify technical pathways and potential responses to space threats.

The market opportunity is not limited to traditional prime contractors. Smaller companies working on optical tracking, radar data, satellite autonomy, maneuver planning, resilient networks, onboard processing, cybersecurity, space logistics, and commercial imagery may become more relevant to defense and security customers. Canada’s Surveillance of Space 2 contract with MDA Space shows how allied nations may invest in domestic space firms to strengthen sovereign capability while contributing to shared coalition networks.

This trend also reinforces the growing overlap between military, civil, and commercial space. U.S. Space Command has described the current environment as one in which national security, civil, and commercial sectors are interwoven. That means allied orbital warfare planning will likely depend not only on government satellites, but also on commercial systems that provide data, communications, manufacturing capacity, and technical innovation.

Policy Challenges For Allied Governments

Allied governments face several policy challenges as they develop a shared orbital warfare concept. The first is classification. Military space activity often involves sensitive capabilities, but multinational operations require enough information sharing to support coordination. Too much secrecy can limit integration; too little protection can expose vulnerabilities.

The second challenge is national authority. Even close allies may have different legal authorities, parliamentary oversight models, military doctrines, and public expectations. A shared concept of operations must account for these national differences while still enabling timely action during fast-moving events in orbit.

The third challenge is escalation management. Space systems are deeply connected to nuclear command and control, missile warning, conventional military operations, and civilian infrastructure. Actions that affect satellites can be interpreted through several strategic lenses at once, making careful coordination especially important.

The fourth challenge is debris and sustainability. A conflict in orbit could damage satellites, create debris, increase collision risk, and reduce the usability of important orbital regimes. The long-term consequences could affect countries and companies not involved in the original conflict.

How The Plan Fits Into A Larger Shift

The allied orbital warfare plan fits into a broader movement toward treating space as an integrated military domain. The Combined Space Operations Initiative met in April 2026 and stated that the space domain has become more complex and less secure, with offensive capabilities putting shared interests at risk. The same statement said members would prioritize and align activities to protect and defend freedom of access and use of outer space, with a particular focus on Operation Olympic Defender.

The U.S. Space Force’s 2025 Space Warfighting framework similarly emphasized space superiority as a joint force priority and identified orbital warfare, electromagnetic warfare, and cyberspace warfare as mission areas for counterspace operations.

Together, these developments show that allied space policy is moving beyond passive resilience. Resilience remains important, but the emerging model also includes active defense, maneuver, combined domain awareness, commercial integration, and planning for contested operations.

The Central Message

The central message is that the United States and its closest space allies are preparing to coordinate military operations in orbit more directly than before. The planned concept of operations is not merely a policy statement; it is intended to guide how allied national capabilities may be integrated, synchronized, deconflicted, and used to protect orbital assets.

The effort is being shaped by recent operational experience. Operation Selene, earlier U.S.-France and U.S.-UK activities, prior space domain awareness concepts of operations, and Apollo Insight industry exercises all point to a defense environment where military space planning is becoming more structured, more multinational, and more connected to commercial capability.

The most important strategic implication is that allied defense of space systems is becoming a standing mission rather than an occasional coordination activity. Space is no longer treated only as a background layer supporting terrestrial operations. It is becoming a domain in which deterrence, defense, maneuver, surveillance, industry integration, and international law must be managed together.

Summary

The reported allied orbital warfare plan represents a major step in the maturation of military space cooperation among the United States, Australia, Canada, France, Germany, New Zealand, and the United Kingdom. Through Multinational Force Operation Olympic Defender, these countries are moving toward a shared concept for protecting orbital assets, integrating national capabilities, and coordinating responses to threats in space.

The effort is driven by a more contested space environment, the growth of counterspace capabilities, the importance of satellites to military and civilian life, and the need for better allied space domain awareness. Operation Selene, Apollo Insight exercises, and prior allied rendezvous and proximity operations show that the plan is grounded in recent activity rather than abstract doctrine.

The opportunity for allied governments is to create a stronger deterrent posture that protects space systems without increasing instability. The challenge is to do so in a way that preserves international law, limits escalation risk, protects commercial and civilian infrastructure, and keeps the orbital environment usable for all responsible space actors.
