Weaponry
The Chinese anti-satellite system has been named by the Director of the Defense Intelligence Agency, Lieutenant General Michael Maples, in a Senate Armed Services Committee Hearing as the SC-19. The SC-19 has been described as being based on a modified DF-21 ballistic missile or its commercial derivative, the KT-2 with a Kinetic Kill Vehicle mounted. The ASAT kill vehicle relies on an imaging infrared seeker and also has been described as a modified HQ-19 surface-to-air missile. The program is said to have been at least partially funded by China's 863 Program (specifically, the 863-409 focus area). The closing velocity of the intercept was approximately 18,000 miles per hour, comparable to the American National Missile Defense system.
