Space Became a Battlefield in 2007, and the Space Force Is the Answer

Folks, I love a good joke about the Space Force. The costumes, the cartoons, the idea of a Navy fleet in orbit with a snack bar. It is one of the great softball pitches of modern comedy. But here is the thing about a joke: it works best when the thing you are laughing at is not the only thing between you and a dark phone, a dead cash machine and a missile that cannot find its target. The comedians have been so busy with the uniforms that they missed what happened on January 11, 2007.

Let me tell you what happened, and then let me tell you why a country that laughs at its newest military branch is a country that has stopped reading its own newspaper.

The day China shot down its own satellite

On January 11, 2007, China launched a ballistic missile, a kinetic kill vehicle carried by a missile known in the West as the SC-19, and destroyed one of its own aging weather satellites, Fengyun-1C. The satellite was in a polar orbit at roughly 860 kilometers. The test was a success in the narrowest sense: the missile hit a target that was moving at thousands of miles an hour, in space, and obliterated it.

There was no explosion to see. You do not hear anything in a vacuum. What you get is physics. The collision broke the satellite into an enormous cloud of fragments, and tracking networks eventually catalogued more than three thousand pieces of debris large enough to follow, with many times more too small to track. Because the satellite was so high, much of that debris would not come down for decades. It is still up there, moving at orbital speed, on paths that cross the orbits of other spacecraft.

I want you to hold two facts together. First, China demonstrated that it could reach a satellite in low Earth orbit with a missile launched from the ground. Second, it chose to do so in a way that littered the most valuable real estate in the sky with a permanent hazard. The first fact is a capability. The second is a statement of how little the Chinese government cared who else lived in that neighborhood.

Beijing said nothing for days: the test was first reported by a trade magazine, and China's Foreign Ministry acknowledged it on January 23. The reaction from several governments was sharp. The test created the largest debris field in the history of spaceflight. Later, other nations would add to the pile: Russia destroyed one of its own satellites in a November 2021 test that forced the astronauts aboard the International Space Station to shelter, and India conducted its own test in 2019. A pattern was clear. Anti-satellite weapons were no longer a Cold War exhibit. They were a menu item.

The United States, to be fair, is not a spotless observer. It tested an anti-satellite missile fired from an F-15 in September 1985, and in February 2008 a Navy ship fired a modified missile to destroy a failing American satellite, USA-193, in an operation Washington described as necessary because of the hazard from its fuel tank. The difference was that the American intercept took place at a much lower altitude, about 247 kilometers. But I do not want to wave away the fair point: the capability is not exclusive to one flag. The point is that the 2007 test put all of us on notice that the sky was now a contested domain.

Why the sky matters more than the jokes suggest

Let me connect this to your Tuesday morning.

The Global Positioning System is a constellation of satellites, operated by the United States government, that broadcasts timing and location signals. Your phone uses it. So does your car, the delivery truck, the ride-share app, the farmer's tractor that steers itself across a field to within a few inches. But the real surprise is not navigation. It is time. GPS carries an extremely precise clock signal, and a stunning amount of the economy runs on it: cellular networks stay synchronized with it, financial markets timestamp trades with it, and power utilities use it to keep parts of the grid in step.

The system is free to everyone on earth. It was built for the military and opened to the public, and the world built an economy on top of it. That is a remarkable gift, and it also makes a remarkable target. Take out or jam enough satellites and you do not need to invade anybody. You blind their navigation, scramble their communications, and slow their economy to a crawl.

Now add the military layer. Modern American forces see, talk and strike through space. Missile-warning satellites detect launches. Communications satellites link commanders to units. Imaging satellites watch troop movements. Precision-guided munitions use satellite signals to find their targets. An adversary who can cut those links does not have to match our fleet. He only has to blind it.

That is the premise of any serious military: you do not beat the strongest force at its strongest point, you beat it at the point where it depends on something fragile. For a generation, the American way of war depended on the sky, and a rival noticed. So the policy question is not whether the high ground matters. It is whether we want a military branch whose entire job is to hold it, or whether we want to leave that job as a sideline for a service with other priorities.

What the 1967 treaty actually says

I hear a version of this objection all the time: "Doesn't a treaty keep weapons out of space?" Let me read the thing so you do not have to.

The Outer Space Treaty entered into force in 1967. The United States, the Soviet Union and the United Kingdom were among the first signatories, and it has since gathered well over a hundred parties, China among them. It does a number of things. It says outer space is free for exploration and use by all states. It says no nation can claim sovereignty over the moon or other celestial bodies. It says states bear international responsibility for their national activities in space, including those of private companies, under Article VI. And in Article IV it addresses weapons: the parties undertake not to place in orbit around Earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction, not to install such weapons on celestial bodies, and not to station them in outer space in any other manner. It adds that the moon and other celestial bodies are to be used exclusively for peaceful purposes.

Now notice what it does not say. It does not ban conventional weapons in orbit. It does not ban a ground-launched missile that destroys a satellite. It does not forbid military satellites; every major space power operates them, and many of the early ones were designed to watch for treaty violations. The treaty is a ban on a particular category, weapons of mass destruction, and a statement of principles about peaceful use. It was a good treaty for its time and its purpose. It was not a force field.

So here is the first honest conclusion: the law of space does not stop the destruction of a satellite. What stops it is the credible ability to retaliate, to defend, and to keep the system working when someone tries. That is not a legal matter. It is a military one. And you do not build military capability with a speech about peaceful purposes. You build it with an organization.

The argument, in four steps

Here is the numbered argument. I promised you one.

1. Space is now critical infrastructure. The economy and the armed forces both depend on satellites for navigation, timing, communications and warning. A loss would be felt everywhere, not just in uniform.
2. Rivals have shown the means and the will. China's 2007 test was the clearest proof, followed by tests by Russia and India. The capability to hold satellites at risk is not a theory.
3. The law does not protect us. The 1967 treaty bans weapons of mass destruction in orbit and sets principles for peaceful use. It does not prevent a missile from killing a satellite. Deterrence and defense do the protecting.
4. Defense needs an owner. Before the Space Force, American military space work was spread across the services, with the largest portion under Air Force Space Command, which had existed since 1982. A function that belongs to everyone tends to be nobody's first priority when budgets get tight. A service with its own budget, its own culture, and its own senior voice at the table cannot be quietly traded away for the next aircraft program.

That fourth premise is the heart of it. Every new military domain in history faced the same objection: that the existing services could handle it. They said it about air power in the 1940s, when the Army Air Forces were a part of the Army. The independent Air Force came in 1947, and few historians of the Cold War would argue that it was a mistake. Organizations get what they care about. A service that has to ask for satellite money from a pilot's budget will ask quietly.

The creation of the Space Force

The Space Force was established by the National Defense Authorization Act for Fiscal Year 2020, which President Trump signed on December 20, 2019. It became the sixth branch of the Armed Forces. It sits inside the Department of the Air Force, in the way the Marine Corps sits inside the Department of the Navy, and it is led by a Chief of Space Operations.

I want to point out what that structure means. Congress, which holds the power under Article I, Section 8 of the Constitution "To raise and support Armies" and "To provide and maintain a Navy," and "To make Rules for the Government and Regulation of the land and naval Forces," did what the Constitution tells it to do. It reorganized the military by statute. This was not an executive gimmick. It was a legislative act, passed with bipartisan support in a defense bill, and it was the Congress using its enumerated powers to answer a new problem. That is how the system is supposed to work. For more on those powers and what they leave to a President, see Commander in Chief Means Less Than Presidents Claim and More Than Critics Say.

What does the Space Force do? It organizes, trains and equips forces for space operations: missile warning, satellite communications, GPS operations, space surveillance, and defending those assets. Most of its people do not wear a spacesuit. They sit at consoles. They are, in the unglamorous way of military work, the ones making sure the signal stays on. If you want to understand why that matters, ask what would happen to a precision strike without a signal.

The strongest objections

Let me give the critics their best arguments, because they have a few.

It adds bureaucracy. Every new service needs a headquarters, a staff, a set of regulations. That is true, and conservatives are right to watch for it. But the answer is to measure it, not to refuse the mission. The Space Force is small compared with the other branches, and it draws on existing Air Force personnel. If it grows into a thicket, the right tool is oversight, not repeal.

It could have been a corps inside the Air Force. Some critics, serious ones, argued that a separate service was not needed and that the Air Force could have fixed its own space priorities. It is a respectable position. My reply is the history: Air Force Space Command had existed for decades, and the 2007 test and the years after it showed how much attention the problem had actually received. A dedicated service concentrates attention. You may still prefer a different structure, but you cannot argue that the old one had worked.

It militarizes space. This one has it backward. Space was militarized in the 1950s. The first satellites were military projects. What changed in 2007 is that someone demonstrated he could attack them. Pretending that an unarmed sky is the status quo does not produce an unarmed sky. It produces one where only the aggressive side has weapons.

It could provoke an arms race. Deterrence is not provocation. Our rivals were testing weapons before we organized a service. A strong defensive posture reduces the temptation to strike first, because it reduces what a first strike gets you. See Mutual Assured Destruction Versus Missile Defense, the Debate Never Ended for the long argument about whether defense stabilizes or destabilizes.

The cost question

Conservatives should demand to know what it costs and whether it works. That is the right instinct. But the cost should be weighed against what the satellites it protects are worth. A single modern GPS or missile-warning satellite costs a great deal to build and launch, and the economy that rides on those satellites is far larger. For the budget picture overall, see Defense Spending as a Share of the Economy, From Korea to the 2010s. A nation that spends heavily on aircraft carriers but leaves the sky to chance has bought an expensive ship and left the compass in the glove compartment.

And there is an industrial question. Launching, building and replacing satellites requires factories, engineers and supply chains that do not appear overnight. The earlier lesson of wartime production applies here: a country must be able to make what it needs, fast. See The Shipbuilding Gap with China Is an Industrial Story Before a Navy Story for the parallel at sea, and The Defense Production Act of 1950 Is a Wartime Tool with Peacetime Habits for the legal tools government has used to speed it.

What the joke gets right, and what it gets wrong

I said I would give the comedians their due. The joke is partly right. Any new organization invites ridicule, and any government unit deserves skepticism. Humility is good for institutions. The Space Force should be asked, regularly and in public, to justify its budget.

Where the joke goes wrong is in assuming the mission is silly. The mission is the oldest one in warfare: hold the high ground. Armies have fought over hills, navies over straits, air forces over the sky above the battle. Now the hill is a few hundred miles up, and it carries the signals that run a modern country. The country that loses it will not lose it in a dramatic scene. It will lose it quietly, one dead satellite at a time, and the first sign will be a screen that stops working.

That is not a punchline. It is a reason to be grateful that somebody, somewhere, stays up all night watching the sky.

The case in brief

1. On January 11, 2007, China destroyed its own satellite with a ground-launched missile, proving it can hold orbiting assets at risk and littering low orbit with thousands of tracked fragments.
2. GPS, communications and missile warning satellites underpin both the economy and the military, so an attack on them is an attack on daily life.
3. The Outer Space Treaty of 1967 bans weapons of mass destruction in orbit and sets peaceful-use principles, but it does not ban conventional weapons or anti-satellite missiles.
4. Defense of the high ground needs an owner with its own budget and voice, which is why Congress created the Space Force in the defense authorization signed December 20, 2019.
5. Skepticism about cost and bureaucracy is healthy, and the answer is oversight, not pretending the sky is safe.

What you can do: read the Constitution's Article I, Section 8 on Congress's power over the armed forces, then ask your representative how the Space Force's budget request compares with the satellites it protects.
