Defence capabilities of US, Russia and India are some of many factors forcing China to modernise its nuclear force and strengthening its strategic strike capabilities, the Pentagon has said.
The Pentagon, in a report to Congress, said China was deploying new command, control and communications capabilities to its nuclear forces to improve control of multiple units in the field.
It said that China insists that the new generation of mobile missiles, with warheads which consist of independently targeted re-entry vehicles (MIRVs) and penetration aids, are intended to ensure the viability of its strategic deterrent in the face of continued advances in the US and, to a lesser extent, Russian strategic ISR (Intelligence, surveillance and reconnaissance), precision strike, and missile defence capabilities.
"Similarly, India's nuclear force is additional driver behind China's nuclear force modernisation," the Pentagon said in its report.
With help of improved communication links, ICBM (intercontinental ballistic missile) units now have better access to battlefield information and uninterrupted communications connecting all command echelons, the report said.
As per Pentagon, China is working on a range of technologies to counter the US and other countries' ballistic missile defence systems.
