President Trump’s top military adviser, Gen. Dan Caine, has urged American troops to prepare for combat in space around the moon, marking a significant shift from previous policies. This comes after Air Force Secretary Troy Meink revealed that the US now has operational "on-orbit space control weapons," despite international norms aiming to keep outer space non-militarized. Lt. Gen. Gregory Gagnon of the Space Force emphasized that potential adversaries like China are developing their own capabilities in space, prompting a response from the U.S. military. China’s foreign ministry spokesperson has responded by calling for adherence to peaceful use and opposition to militarization of space.

Story summary
At the Air, Space and Cyber Conference in Maryland, Gen. Dan Caine, chairman of the Joint Chiefs of Staff, emphasized the urgent need for U.S. troops to prepare for combat in cislunar space and on Earth's orbit, not just in response to China and Russia’s advancements but as humanity advances further into space. The Space Force—established by Trump in 2019—recently activated the 77th Surveillance Squadron, responsible for detecting moving targets in space, reflecting a growing military presence there. This comes days after Troy Meink, Secretary of the Air Force, confirmed that the U.S. now has weapons deployed in orbit to maintain "space superiority." While nations like the U.S., Russia, and China have demonstrated satellite destruction capabilities from Earth, the Space Force’s current mission highlights a shift towards more active space warfare readiness amidst growing concerns over potential adversaries extending conflict into space.

Space Force says potential US foes may look to turn space into a battleground
While several nations, including the US, have previously demonstrated the ability to destroy satellites in Earth orbit, those tests were conducted from terrestrial locations against their own assets.
According to Gagnon, however, "the intelligence community has been clear that potential adversaries have been seeking to extend warfare into space," compelling a reaction from the US military.

Treaty signed by the US says space is for peaceful purposes
The 1967 Outer Space Treaty, ratified by both the US and China, mandates that celestial bodies, including the moon, be used "exclusively for peaceful purposes," prohibits nuclear weapons in orbit, and dictates that nations remain "liable for damage caused by their space objects."
A renewed effort to strengthen UN anti-militarization rules occurred two years ago following US intelligence indicating Russia was constructing a space-based weapon.
Russia vetoed a joint US-Japanese resolution at the UN that called on all nations to refrain from deploying nuclear arms or weapons of mass destruction in space.
