Simulation: DF-21D 'Chinese Carrier Killer'
An artist impression of the Chinese DF-21 ballistic guided missile's anti-ship capability. The simulation shows the missile launched against an aircraft carrier. The missile releases the upper stage that uses steering nozzles to position the payload on the required trajectory, while dodging missile interceptors in space...
Before reentering the upper atmosphere the upper stage releases the unitary warhead protected by the reentry vehicle. This section is also equipped with decoys and pyrotechnical charges that are kicked in to avoid missile interceptors and reposition the warhead on target.
According to missile experts, such terminal manoeuvring isn't necessary when nuclear warheads are used, but would be useful for conventional attack. DF-21 is likely to carry a 0.3-0.5kt nuclear warhead or several conventional warheads.
Another intriguing part of this video is the upper stage 'dodging' missile interceptors, since this element doesn't have the means to respond to incoming interceptors. Hence, these manoeuvres are more likely to be pre-programmed rather than reactive.
