India to test-fire 3,500 km range K-4 nuclear missile on Friday

To further strengthen its capabilities of hitting enemy targets from submarines, India is planning to test-fire the 3,500 kilometre strike-range K-4 nuclear missile from an underwater platform off the coast of Andhra Pradesh on Friday.
The missile system is being developed by the DRDO for the Arihant class nuclear submarines which are being built by India. These submarines would be the mainstay of India's nuclear triad. "As per plans, the DRDO will carry out test-firing of the K-4 nuclear missile from an underwater platform off the Vishakhapatnam coast on Friday. During the trial, the DRDO will test the advanced systems in the missile system," government sources said here.
