Why It Matters
The US established the Space Force in 2019 under President Trump as its sixth military branch. Recent developments include the revelation of deployed on-orbit space control weapons and preparations for operations in cislunar space, the region between high Earth orbit and the moon.
American troops need to prepare for combat not only in Earth’s orbit but around the moon, President Donald Trump’s top military adviser said on Wednesday, looking ahead to a new frontier in warfare after the US revealed for the first time that it has deployed weapons in space.
General Dan Caine, chairman of the Joint Chiefs of Staff, told service members and industry figures at the Air, Space and Cyber Conference outside Washington that the US military should adapt now so it “is prepared to fight, endure and win … from the seabed to cislunar space”.
Space Force, the newest military service, which was created by Trump in 2019, is preparing to fight in space and around the moon because “humanity is advancing deeper into space – the Space Force’s job is to help be prepared to defend US interests,” Lieutenant General Gregory Gagnon, head of the force’s Combat Forces Command, told reporters separately.
The announcement that the US military is ready to fight in the area between high Earth orbit and the moon itself comes days after Air Force Secretary Troy Meink revealed at the same conference that the US has fielded “on-orbit space control weapons”.
