The United States military is being urged to prepare for the possibility of conflict extending beyond Earth’s orbit and into the region surrounding the Moon, as Washington places greater emphasis on military capabilities in space.
General Dan Caine, chairman of the US Joint Chiefs of Staff and one of President Donald Trump’s senior military advisers, said American forces must be prepared to operate across a wider range of environments, including cislunar space — the area between Earth and the Moon.
His comments came as the United States publicly acknowledged for the first time that it has deployed weapons in Earth’s orbit. Air Force Secretary Troy Meink disclosed the existence of what he described as “on-orbit space control weapons”, although officials have not publicly detailed the systems or how they would be used.
The developments reflect a growing focus within the US military on space as a potential theatre of conflict. Satellites already play an important role in communications, navigation, intelligence gathering and missile-warning systems, making space infrastructure increasingly important to national security and military operations.
Caine’s warning also comes as the US Space Force prepares to expand its capabilities. The service, created in 2019, has been directed to increase its focus on combat operations and protecting American interests in space. Officials have identified cislunar space as an increasingly important area as more countries develop ambitions for lunar exploration and other activities beyond Earth’s immediate orbit.
US military officials have pointed particularly to China as a potential strategic competitor in space. American assessments indicate that rival powers are developing capabilities that could interfere with or attack satellites and other space-based assets.
China, meanwhile, has rejected suggestions that its space activities are intended to promote conflict and has reiterated its position that outer space should be used peacefully.
The possibility of military confrontation around the Moon remains far removed from conventional warfare on Earth. There are currently no reported battles in cislunar space, but military planners are increasingly considering how future conflicts could affect satellites, spacecraft and infrastructure operating farther from Earth.
The issue also raises questions about international law.
The 1967 Outer Space Treaty prohibits countries from placing nuclear weapons or other weapons of mass destruction in orbit or stationing them on the Moon and other celestial bodies. It also establishes that the Moon and other celestial bodies should be used for peaceful purposes. However, the treaty does not prohibit every form of conventional military activity or military technology in space, leaving important areas of modern space warfare subject to continuing international debate.
The recent American disclosure has therefore attracted attention beyond Washington. The development could encourage other major powers to increase their own counter-space capabilities, particularly if they conclude that military systems in orbit are becoming essential to national defence.
The United States maintains that its space capabilities are intended to deter attacks and protect critical national interests. Critics have warned that increasing military deployments in orbit could instead contribute to an arms race and make space less secure for everyone.
For the US military, however, the strategic calculation is changing as human activity moves farther into space.
Future missions involving lunar exploration, communications, navigation and commercial activity could create new infrastructure that countries may seek to protect. Military planners are therefore increasingly looking beyond traditional satellite warfare and considering what happens as activity expands towards the Moon.
The prospect of fighting around the Moon remains largely a future scenario. But the latest statements from senior American military officials show that preparations for possible conflict in space are no longer being discussed only as science fiction.
