Among defense experts the world over, there's little doubt that warfare in the 21st century will be an orbital affair. From communications and reconnaissance to navigation and logistics, you'll be hard-pressed to find an element of any modern nation's military that operates without the use of space-born satellites, and as such, many nations are developing weapons aimed specifically at causing trouble high above our heads.
While the U.S. government may be no exception, as the reigning space-race champ, America has the lead, and as such, much more to lose in orbit than its national competitors. At least one element of the Pentagon has a plan to help keep it that way: an orbiting space station purpose-built to support a fleet of defensive space drones.
Which beats out my proposal to just start dropping bombs from the ISS, I suppose.
You might be imagining a space station equipped with the latest defense gadgets, science experiments meant to usher in the next era of orbital weapons, and of course, enough utility to support a wide variety of Pentagon directives in the dark skies around our pale blue dot… and you'd be right on all counts… but where this new initiative breaks from fantasy is in its size. The Pentagon's proposed space station wouldn't be built to sustain any kind of manned presence whatsoever, at least for now.
The proposed orbital outpost received a great deal of media attention recently thanks to an industry solicitation posted by the Pentagon's Defense Innovation Unit (DIU). Put simply, the solicitation is seeking companies that want to compete for a chance to help launch a self-contained orbital facility that's "capable of supporting space assembly, microgravity experimentation, logistics and storage, manufacturing, training, test and evaluation, hosting payloads, and other functions."

The DIU envisions an orbital outpost that's equipped with robotic arms to manage assembly and even potentially repair duties for other orbital assets. That means this unmanned installation could feasibly be used to build autonomous satellite drones in space meant to help protect America's large and rather undefended constellation of satellites.
The tiny outpost would have a payload capacity of just 176 pounds (or 80 kilograms if you live in a nation that's never sent people to the moon), and would offer only a small 3 foot by 3 foot by 4 foot enclosure. That may not be enough room to house any members of the space infantry, but it would be enough to work on things like cube-sats, which are small, inexpensive satellites built to serve specific purposes in orbit and beyond.
Because the reality of war in space could be as mundane as simply nudging a satellite out of its orbit, cube-sats and other small platforms could actually play a massive role in orbital combat operations. A fleet of inexpensive satellites could provide system redundancy by temporarily filling service gaps as other assets are destroyed or interfered with by enemy platforms. They could also engage with or deter enemy systems (be they satellites or weapons themselves).

Thanks to advances in 3-D printing and a rash of commercial interest in orbital manufacturing in recent years, it seems entirely possible that an orbital outpost like the one proposed by the DIU could eventually support a broader space defense initiative, but it also seems unlikely that this specific enterprise would ever expand far enough to add human support to the equation, but then, humans may need to be present anyway.
Russia and China are both already believed to operate orbital weapons platforms that behave like autonomous satellites and the Air Force's secretive space plane known as the X-37B operates in orbit for months at a time without any use for human hands. Star Wars may indeed eventually come to fruition, but at least for now, it looks like the fighting will be up to R2-D2, with all of us Skywalkers just watching anxiously from the ground.
