The CSS-NX-5 is an intercontinental-range, submarine-launched, solid propellant ballistic missile under development in the People�s Republic of China (PRC). It is the submarine-launched ballistic missile (SLBM) of the newest generation of PRC missiles. It is believed to have been developed along with the DF-23 land-based missile, which was later redesignated to the DF-31 (CSS-9). The CSS-NX-5 is reported to be similar to the CSS-9 and it is considered possible for the two missiles to be nearly identical. The CSS-NX-5 is designed for launch from the PRC Type 94 missile submarine, to replace the aging CSS-N-3 missiles currently in operation.
The CSS-NX-5, unlike the CSS-N-3, truly secures the PRC missile force against attack. The CSS-NX-5 has sufficient range to strike US and Russian targets from PRC territorial waters, protected by the PRC air force and navy. Its mobility is such that once at sea it can avoid detection and conduct missile launches before it can be found and destroyed. As it can be equipped with Multiple Independent Reentry Vehicle (MIRV) warheads, a single missile can be used to destroy multiple targets, dramatically increasing the damage a single missile submarine could inflict. And as the submarine can also transport the missiles to locations near the target, everywhere in the US and Russia is vulnerable. The CSS-NX-5 missiles can be hidden and protected against a first strike, can inflict considerable damage on their own, and can strike any target within the United States.
Unlike the CSS-N-3, the CSS-NX-5 is not necessarily a first strike weapon. Despite the fact that the missile submarine force is too small to truly provide a guaranteed deterrent, the CSS-NX-5 has sufficient range to allow the missile submarine to be heavily guarded in PRC territorial waters. Though it is still small enough to be theoretically eliminated prior to a first strike, it can be defended sufficiently to not be worth the risk of launch. However, the CSS-NX-5 still has distinct advantages as a first strike weapon. It can be positioned near US waters and be launched without warning. This would prevent a successful evacuation of a target area, such as the White House, and would enable high level strategic targets to be destroyed with minimal warning. The estimated accuracy is insufficient for use against missile silos with MIRV warheads, and single warhead missiles could not be deployed in sufficient numbers to hinder US or Russian missile forces. However, a large quantity of the US missile force will be vulnerable to a first strike should PRC guidance systems be upgraded to the point where a SLBM MIRV warhead can successfully destroy a hardened silo.
The CSS-NX-5 has a minimum range of 2,000 km (1,243 miles), a maximum range greater than 8,000 km (4,971 miles), and carries a payload of 1,050 to 2,800 kg. This payload is believed able to be equipped with either a single 1 MT yield nuclear warhead or between 3 and 8 MIRV warheads. The MIRV warheads probably weigh between 250 and 300 kg apiece and can be set to a nuclear yield of 20, 90 or 150 kT. The missile will likely be capable of being equipped with penetration aids to decrease the effectiveness of anti-missile defense systems. The system uses an inertial guidance system with stellar updates and a Global Positioning Satellite (GPS) system. An accuracy of 300 m CEP has been suggested, but other reports suggest 150 m CEP, which seems to better reflect current guidance technology. The missile uses a three-stage solid propellant engine.
The CSS-NX-5 is believed to have entered the initial design stage in 1970 along with a land-based DF-23, but both were redesigned in 1985 following an operational requirement change. This change probably occurred to take into account advancements in PRC warhead miniaturization technology. The CSS-NX-5 is expected to enter service in 2005, onboard the first Type 94 nuclear missile submarine expected to be completed that same year. Between four and six Type 94 submarines are expected to be built, carrying 16 to 18 CSS-NX-5 missiles each. It is considered possible that the remaining �Xia� class submarine was modified to carry CSS-NX-5 missiles, but it is probable that upgraded CSS-N-3 missiles were installed instead.(1)
