China’s 2021 orbital-weapon tests

In mid-2021, China launched two unprecedented test weapons that travelled long distances in low-Earth orbit before releasing hypersonic gliders into the atmosphere, which hit targets on Chinese territory. Much is unknown about these tests, but this ‘orbital glider-release system’ is a new technology that could substantially increase China’s nuclear second-strike capabilities against the United States and serve as a hedge against the deployment by the US of new missile-defence systems.
