Staff Reports
Gen. Dan Caine, chairman of the Joint Chiefs of Staff, told a crowd at the Air and Space Forces Association conference that the U.S. military “is prepared to fight, endure and win … from the seabed to cislunar space.” In plain English: America must be ready to fight not just in orbit around Earth but in the space between our planet and the Moon. That’s a big shift from yesterday’s thinking, and the Pentagon’s recent admission that it has a weapon in orbit only underlines how real this is.
What the chairman actually said
Gen. Dan Caine wasn’t speaking in metaphors. He named cislunar space — the region between Earth and the Moon’s orbit — as part of the battlespace the U.S. must defend. Lt. Gen. Gregory Gagnon, who runs Combat Forces Command, backed him up: Space Force is preparing to “defend U.S. interests” as humans push farther into space. This isn’t science fiction. It’s planning. If you think the only combat zone that matters is Earth, you’re not reading the room.
Why cislunar space matters for national security
Cislunar space holds strategic value. Future bases, communications relays, navigation nodes, and even mining operations will sit between Earth and the Moon. Whoever controls those platforms can disrupt communications, jam navigation, or deny access to rivals. China and Russia have already shown their willingness to push military capabilities into space. So the idea that we’ll limit our defenses to low-Earth orbit is a recipe for strategic surprise — and defeat.
Pentagon disclosure: yes, there’s a weapon in orbit
The Pentagon’s own recent disclosure that it has a weapon in orbit removed any illusion that space can stay purely peaceful. That admission matters. It changes deterrence and raises the stakes, but it also makes sense. Adversaries test anti-satellite weapons and gray-zone tactics. You don’t answer that by stuffing your head in the sand and signing idealistic treaties. You prepare. Critics who wring their hands about “weaponizing space” forget that deterrence kept the peace on Earth for decades.
Congress and the American people need to match words with budgets and laws. Space Force was created to meet this moment, and it needs the resources to operate in cislunar space, build resilient systems, and work with industry and allies. Call it conservative common sense: hold the high ground, deter aggression, and make sure America’s sons and daughters have the tools to protect the country — whether the fight is on the seabed, in low orbit, or all the way around the Moon. Those who want to pretend space is a utopia for all nations should at least explain how that will stop adversaries who don’t play by the rules.
