National missile defense

Missile defense systems are a type of missile defense intended to shield a country against incoming missiles, such as intercontinental ballistic missile (ICBMs) or other ballistic missiles. The United States, Russia, France, India, and Israel have all developed missile defense systems.

The role of defense against nuclear missiles has been a heated military and political topic for several decades. However, missile defense is no longer limited to interception of strategic nuclear weapons. The gradual development and proliferation of missile technology has blurred the line between the technologies for the interception of tactical missiles (usually short to intermediate range with non-nuclear payloads) and the interception of strategic missiles (usually long ranged with nuclear payloads). High-performance tactical ballistic missiles carrying non-nuclear payloads now have the ability to affect strategic balance in conflict zones. Likewise, high-performance tactical missile defense systems can now influence force deployment strategies.

China tested the FJ ABM in the Cold War but they were ultimately cancelled. The PLA has currently developed the KT series of anti ballistic missiles and also have adopted limited anti ballistic capabilities on the HQ-9, KS series, and HQ-16.

China successfully tested its exoatmospheric interception capabilities in a test in 2010 and also in a test in 2013, being the second of two countries able to do so.

Four versions of the S-300 are in service, the PMU, PMU1 and PMU2 and the navalised S-300FM Rif. Based on the S-300PMU1, the Rif equips the PLAN’s two Type 51C Luzhou air-defence destroyers enabling them to contribute to the protection of a coastal site against SRBM attack.

The S-300PMU2 has the best chance of intercepting an SRBM missile as it employs the 48N6E2 missile which has a warhead optimised for destroying ballistic missiles, and better kinematics compared to earlier 48N6 missiles.
