The Space Force turns five years old on Dec. 20, with Guardians everywhere preparing to celebrate.
Yet public awareness of the Space Force remains low, acknowledged Katharine Kelley, Deputy Chief of Space Operations for Human Capital.
“If you look at that data, less than 8 percent [of the public] even know we exist, and a smaller subset of the national population can describe what we do,” Kelley said this week at the Center for Strategic and International Studies.
So, on the occasion of this milestone, here are five things to know about the Space Force and why it matters for the rest of the military and all Americans.
Getting Bigger and Bigger
Back on Dec. 20, 2019, the Space Force had just one member: Gen. John W. “Jay” Raymond. In the five years since, it has expanded at an astonishing rate.
“We have tripled in size every year for the last five years in personnel,” said Gen. B. Chance Saltzman, Raymond’s successor as the service chief.
Now, the Space Force boasts almost 15,000 military and civilian personnel, Saltzman said, including approximately 9,400 Active-Duty Guardians. It’s still the smallest military branch by number of service members, but those Guardians are responsible for a budget of roughly $29 billion and missions around the world and in orbit.
Everyday Services
When it comes to explaining what exactly it is the Space Force does, leaders often start by asking people if they use their phones to navigate to work, stop at an ATM, or fly on a plane. All of them rely on the Global Position System, a collection of satellites operated by the Space Force. Indeed, GPS is used for everything from agriculture to financial markets to scientific research.
According to some estimates, if GPS were to go down for 15 minutes, it would cost the U.S. economy around $1 billion.
On top of GPS, the Space Force is also responsible for tracking tens of thousands of objects in space, using a combination of satellites, telescopes, and antennae to do so. That’s critically important for making sure objects don’t collide and create more debris. Debris lingers in space and can threaten government or private satellites that provide internet access, communications, and imagery.
Missile Warning
The Space Force doesn’t just provide navigation, timing and collision avoidance services. It’s also responsible for protecting U.S. service members around the globe. That’s the focus of its missile warning satellites and radars.
Guardians operate overhead persistent infrared satellites like the Defense Support Program and Space-Based Infrared System that can detect heat from missile and booster plumes and share that data with Joint Tactical Ground Stations to give troops advance warning of an incoming attack.
Radars like the Upgraded Early Warning Radar, Perimeter Acquisition Radar Attack Characterization System, and Long Range Discrimination Radar track those missiles and help guide interceptors to take them out—an incredibly difficult technical task that officials sometimes describe as “hitting a bullet with a bullet.”
The Space Force alerted troops to incoming attacks in the Middle East in 2020, and more recently alerted U.S. forces of pending attacks on Israel, enabling a coalition of forces to intercept hundreds of incoming missiles.
Assured Communications
Through its satellites, the Space Force provides communications for supporting some of the military’s most vital missions. For example, the Advanced Extremely High Frequency Satellite System provides the secure communications necessary for nuclear command and control. The Pentagon’s essential mission of nuclear deterrence depends on having assured comms, so the service has to make sure those satellites stay secure and operational at all times.
Threats in Space
Not only does the Space Force help protect people and essential services on Earth, it is also responsible for defending U.S. assets in space—and that task is getting harder all the time as countries like China and Russia test out ways to destroy or disrupt satellites.
Knowing that the U.S. military uses space for navigation, missile warning, communications, and more, adversaries are experimenting with missiles that can shoot up from Earth to take out orbiting satellites, arm their own satellites with the means to grab and move another satellite, and put in orbit weapons that can fire projectiles to damage other satellites. Russia has even floated putting a nuclear weapon in space.
The Space Force not only monitors those threats, it is working on what it calls “orbital warfare” to make sure it can counter anything adversaries try to hurt the U.S. in space. Developing the means to hold others at risk—that is, to field its own offensive weapons in space—is increasingly a capability the Space Force says it needs. That is something the infant USSF is likely to develop in the coming years.
Supporting Spaceflight
When most of the public thinks of space, they think of NASA and its human spaceflight program—or perhaps the growing trend of commercial firms sending humans to space.
The Space Force doesn’t typically put Guardians in orbit—though one Guardian, Col. Nick Hague, is currently on the International Space Station as a NASA astronaut. The service does, however, play a key role. It operates multiple launch complexes at Cape Canaveral Space Force Station, Fla., and Vandenberg Space Force Base, Calif., and it provides situational awareness and collision avoidance warning for the International Space Station and rockets carrying humans into orbit.
