China's Anti-Stealth and countermeasures

China employs a range of “anti-stealth” and similar ‘asymmetrical’ air-defenses. These not only attempt to target stealth aircraft but also to shoot down or prevent cruise missile and precision guided weapons attack.

Foremost among these in my opinion are the anti-satellite program (“Space Denial”). These can disrupt/prevent GPS and spy satellites thus drastically improving the PLAs chances in any scenario with US. Also, because satellites are unmanned shooting them down is politically lightweight in times of limited warfare.

The main anti-satellite weapon of PLA is a ground based ASAT missile called KS-19 by western observers. The missile resembles a ballistic missile and is possibly based on the DF-21 or DF-25 missiles. The weapon was successfully tested in 2007 shooting down a satellite at over 500km altitude.
