The magazine Aviation Week, which first reported the test, said the satellite was hit by a kinetic kill vehicle launched from a ballistic missile.

Since last time China attacked a satellite in 2007(also on 1.11) they've made great improve. GMD and the kkv(kinetic kill vehicle) capability is far beyond that scale.

自从中国上次在2007年用导弹击落卫星（也是1月11日），中国已经取得了很大的进步。

During the terminal guidance phase of the kinetic kill vehicle in the atmosphere, the variable structure guidance law can be used to improve the robustness to unknown escaping maneuver of the target.

Reports last month that China had successfully tested an anti-satellite (ASAT) weapon against one of its own antiquated weather satellites using a kinetic kill vehicle launched on board a ballistic missile raised the stakes in the ongoing battle between the U.S. and China over space supremacy.

As U.S. intelligence revealed last week, the destructive intercept was performed by a kinetic-kill vehicle (KKV) launched onboard a medium-range ballistic missile.

Casualties include a scale-back of the Airborne Laser program to enable enemy missile interceptions during their early launch phase, along with the elimination of the Multiple Kill Vehicle and Kinetic Energy Interceptor which uses small warheads on a single rocket to handle decoys and offer a better chance of success.
