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。

Air Force Space Command data show that when the kill vehicle impacted the target satellite, debris was ejected from the impact point at velocities of up to 1,400 MPH. (2,000 FPS.).

美国空军空间指挥中心的数据表明，当拦截器撞击目标卫星时，碎片会以每小时超过1400英里(每秒2000码)的速度从撞击点飞散出去。

The programs in question are the Clementine II asteroid intercept experiment, the Army's Kinetic Kill Anti-Satellite Weapon and the Military Space Plane.
