Had to this, they are being substituted for missiles DF-21, already described, that they possess minor reach, however they are more modern. Missiles DF-4A possess, as some estimates, reach of seven a thousand kilometers, being, therefore Mssil Balstico Intercontinental (MBI) of limited capacity. Being projected to be capable to reach the American base of Guam, in the Pacific Ocean, and the European Soviet Union, the missile, for the current standards, he is inexact, slow and of complex launching. Its load is exclusively nuclear and it does not have forecast for its substitution. Intercontinental missiles DF-5A are the main vectors of strategical attack of the RPC.
Its ray of allows it to reach to take powerful nuclear weapons the good part of the globe, abstaining itself it South America and small portion of Africa Occidental person. Such vectors possess unbalanced technology, being comparative to the one of missiles developed for the superpowers in the decade of 1950. Beyond slow, the missile is in service in small amount. The estimates vary. However it is given credit that they exist, currently, between nineteen and twenty and five operational missiles. Some sources cite that this inventory is always in state of alert in silos in the south of China, ready to leave to any minute, if necessary.
As and the last intercontinental missile in service in the SAC is the DF-31. Projected to substitute the DF-5A, the missile it possesss lesser reach that its predecessor, therefore being incapable to reach the coast east of U.S.A. Although this, it, in fact, represents a great advance for the Chinese strategical forces, especially due to better precision, to the simplicity of operation and the fact of that it can be operated from mobile bases, as trucks special, making it difficult its destruction before being launched. However, the vector is in operation in insufficient numbers to guarantee an efficient capacity of attack or counterattack.
