K-4 Missile:
India tested an intermediate-range ballistic missile called K-4, which is designed to hit targets 3,500-km away, from the nuclear-powered submarine INS Arighaat in the Bay of Bengal recently.
- Kalam-4 or K-4 Missile, is a nuclear-capable intermediate-range submarine-launched ballistic missile (SLBM) designed mainly for deployment on Arihant-class submarines.
- Each Arihant-class submarine can carry four K-4 missiles.
- K-4 was indigenously developed by the Defence Research and Development Organisation (DRDO).\
- The missile has a two-stage solid-fuel system.
- It has a range of around 3,500 km.
- One of its key features is its ability to be cold-launched from underwater, which allows the missile to be ejected from the submarine before the engine ignites.
- It is guided by an advanced inertial navigation system supported by GPS and India’s NavIC system.
- This combination ensures high accuracy.
- The missile is also equipped with manoeuvring features that help it evade missile defence systems.
