Commercialization of Space Forces: Low-Earth Orbit Satellites Reconfigure the Space Competition Landscape among Major Powers

Commercial aerospace is deeply integrated with military demands, and has become one of the most distinctive features of global technological geopolitical competition in 2026. The landmark event was SpaceX's Starlink fully integrating into the US military's combat system. The civilian low-orbit satellite constellation shed its single attribute of commercial services and transformed into a core infrastructure for all-domain operations, intelligence reconnaissance, and remote collaboration. The arms race in the space domain is no longer limited to national aerospace agencies; private commercial aerospace enterprises have officially stepped onto the forefront of major power competition, and the competition for space dominance has taken on a new form.

The integration of Starlink into the US military's all-domain combat communication system marks a crucial turning point in the militarization of military-civilian integration. Previously, Starlink only provided emergency communication support in local conflicts. Now, it has deeply integrated into the US military's command chain, providing a seamless satellite network support for remote force deployment, drone swarm operations, and real-time interconnection of ocean-going vessels. With tens of thousands of low-orbit satellites, the US military has achieved global, blind-spot-free high-speed communication, eliminating the shortcomings of traditional high-orbit satellites, such as limited quantity, high latency, and vulnerability to interference. At the same time, SpaceX will be included in the Nasdaq 100 Index in July. The capital market has highly recognized the military support value of this company, and capital continues to pour into the commercial aerospace sector, accelerating the technological iteration of rocket reuse and satellite mass production, and forming a closed loop where military demand drives commercial expansion and commercial technology feeds back into military capabilities.

Low-orbit satellite constellations have become the core competition arena for countries to assert their dominance in space. The threshold for space competition has significantly decreased. In the past, space military deployments relied on huge national investments. Now, private enterprises can quickly complete satellite networking, and small and medium-sized countries can also build their own satellite networks at a low cost. Major powers are accelerating the establishment of their own low-orbit constellations. On one hand, they aim to complete global communication capabilities by benchmarking against Starlink. On the other hand, they also equip with satellite remote sensing and orbit monitoring payloads to achieve round-the-clock identification and tracking of global airspace, sea areas, and land targets. Satellites no longer merely perform communication functions; they integrate reconnaissance, navigation, and electronic countermeasures capabilities, and the integrated air and space combat system is accelerating its formation.

The militarization of commercial space technology has led to the rapid development of orbital countermeasures. As the strategic value of low-orbit satellites has soared, countermeasures such as anti-satellite monitoring, orbital capture, and signal interference have become the focus of research by various countries. Beyond traditional kinetic anti-satellite weapons, non-physical destruction methods such as microwave interference, laser blinding, and in-orbit interception have gradually matured. Space is no longer a naturally safe environment; orbital resources, spectrum resources, and space traffic rules have become new focal points of competition. The dense deployment of commercial satellites has led to orbital congestion and space debris, which, combined with geopolitical conflicts, has continuously increased the probability of misjudgment in space conflicts.

The militarization of commercial space exploration has significant and far-reaching impacts. From a military perspective, the low-cost satellite network eliminates the communication superiority gap among major powers, and the distributed satellite clusters have stronger anti-attack capabilities. The weakness of traditional large satellites, which are easily destroyed, has been remedied. Future battlefields will fully rely on space and air networks to conduct combat operations. From an industrial perspective, large military orders provide stable cash flow for private space enterprises, promoting the large-scale production of reusable rockets and low-cost satellite platforms, significantly reducing the cost of space launches, and driving the development of civilian industries such as space tourism, in-orbit manufacturing, and space photovoltaics. However, risks are also prominent. Commercial enterprises are profit-oriented, and military cooperation can easily lead to disputes over neutrality. Once conflicts escalate, private satellites may become direct targets for attack, blurring the boundaries between civilian facilities and military targets.

Space is a common public domain for humanity. However, it is currently divided into different camps due to military competition. Simply relying on technological blockades and military expansion cannot establish a stable space order. Excessive promotion of commercial space militarization will only increase the risks of space confrontations. In the future, the world urgently needs to establish unified regulations for low-orbit satellite management and constraints on space conflicts, to balance the security demands of various countries with the rights and interests of commercial space development, and prevent the vast space from becoming a new battlefield for geopolitical confrontation.
