After nearly two decades of counter-terror operations around the world, the United States military has recently begun shifting its focus away from this form of asymmetric warfare and back toward the potential for near-peer conflicts with nations like China or Russia.

Despite maintaining the most powerful military apparatus on the globe, this pivot won’t be without its challenges. Over the past 19 years, the United States military has funneled the majority of its funding into combat operations and new technologies that support the counter-terrorism endeavor. During this time, national opponents like China have had ample opportunity to observe the way America’s military operates, and find cost-effective methods of countering the U.S.’s most significant strengths.

In 2015, for instance, both China and Russia established space-specific branches of their armed forces tasked with replicating some of America’s orbital strengths (like a GPS satellite constellation), but also with finding ways to mitigate America’s established orbital dominance. Put simply, it’s cheaper and easier to interfere with or destroy technology than it is to replicate it, and America’s enemies have leveraged that simple logic to great effect in recent years. Today, it’s believed that both Russia and China operate semi-autonomous orbital assets that can already spy on or potentially even destroy satellites that are currently in orbit.
