Suppose the US launches strikes upon China's 200 nuclear facilities, DF5A silos, missile storage tunnels and 100 airforce and ground-to-air missile bases in the initial round of nuclear attacks, with 4 warheads aiming at each of the above targets, the total consumption of nuclear warheads would be 1.200.

Let's say the firingsuccess rate is 50%, after the first round of attacks, each of the Chinese target above would have to endure 660-1.000KT nuclear attacks. Such as attacks should be sufficient to give rise to a "nuclear winter" on the land of china and consequently have huge impact on the neighboring countries.

Under the 660-1.000KT nuclear strike, pending on the explosion altitude of the warheads, the direct destruction radius of each explosion would be at least 300km, with the shock wave stretching as far as 500 km.

The impact of nuclear radiation would be more than 1.000 km, and EMP phenomena could influence an area of 1.300-1.500 km. These impacts may lead to the blackout over a vast area of the country, or the dysfunction of computers, trains and autumobiles. A series of subsequent nuclear explosionswould take the whole of China into a state of intense nuclear pollution and the coverage of nuclear EMP.

Major earthquakes may also be induced. Even if DF31 and some of the DF5 storage tunnels remain intact and survive the first round of strikes, how will the launch vehicles and computer systems be started ? Will they still function properly ? There are all big questions with unknown answers.

Affected by formidable X-rays created by nuclear explosions, the DF31 ICBM nuclear warheads in the underground storage tunnels that survive the strike may look intact. But in the course of moving around at the launching sites, to what degree the ignition devices on the warheads would be affected ?

This is another unanswered question.
