The Assassin’s Mace
<snip>
"The architects of China’s military transformation have also placed high priority on the acquisition of so-called shashoujian, or “assassin’s mace” technologies. While the exact meaning of the term remains elusive, the Pentagon report says “assassin’s mace” is used to designate a wide array of technologies that might afford an inferior military an advantage in a conflict with a superior military power. To this end, China has been beefing up its ballistic missile arsenal, which now totals over 500 and is growing at the startlingly high rate of 75 new missiles a year.
Beijing knows, too, that the Achilles’ heel of the modern American military is in outer space, and there is no doubt that China is developing and seeking to employ a variety of anti-satellite weapons. Presently, the only means China is known to possess to disable America’s intelligence and communications satellites is a nuclear warhead. But such weapons are impractical, since the electromagnetic field they create would also damage Chinese satellites. But press reports indicate that China has developed lasers that can disable low-orbiting satellites. China has also developed an array of miniature satellite technologies, and is reportedly experimenting with “parasitic microsatellites” that could potentially latch onto an American satellite and disable it or hijack the information gathered by it."

"A military space war-fighting strategy is also being put in place, some China-watchers claim. That line of attack calls for quick access to orbit, lofting anti-satellites, utilizing powerful ground-based lasers to blind spacecraft - all part of a technological tool kit for denying use of the "high ground" of space by an adversary."

And that's just China.

On a side note; I doubt NASA's DART Mission is solely for the use of sending unmanned cargo ships to space stations too.
