Navy tests 3500 Km range K-4 ballistic missile from submarine INS Arighaat

Indian Navy test fired of the 3,500 Km range K-4 ballistic missile from the newly-inducted nuclear submarine INS Arighaat on Wednesday. According to defence sources, the test results are being analysed. 

Sources said that the ballistic missile test was done for the full range. The details are being analysed and the top military and political brass would be briefed by officials concerned on the exact details after complete analysis.

As part of India’s nuclear deterrence strategy, the K-4 provides the Indian Navy with the ability to conduct second-strike capabilities, ensuring a robust deterrent against adversaries.

What is the K-4 ballistic missile?

The K-4 ballistic missile is an intermediate-range, submarine-launched ballistic missile (SLBM) developed by India's Defence Research and Development Organisation (DRDO). It is part of India's nuclear deterrence strategy, designed for second-strike capability as part of the country's nuclear triad. The missile is designed to be launched from Arihant-class nuclear-powered submarines, ensuring stealth and survivability.

The K-4 missile has an operational range of approximately 3,500 kilometers, making it capable of striking deep into enemy territory. It can carry a nuclear warhead with a payload capacity of up to 2,000 kilograms, although the warhead is typically much lighter for strategic purposes.

The K-4 features maneuverable re-entry vehicle (MaRV) technology, enabling it to evade missile defense systems. The missile uses a solid-fuel propulsion system, which offers greater stability and ease of storage compared to liquid-fueled systems. 

The K-4 missile employs an advanced inertial navigation system (INS) combined with satellite guidance for precise targeting. The missile is equipped with advanced ring laser gyroscopes for enhanced accuracy.
