NEW DELHI: India on Sunday successfully test-fired 3500 km strike range nuclear-capable submarine-launched K-4 ballistic missile. The test-fire took place near the coast of Andhra Pradesh.

The test-firing was carried out from an underwater platform in the sea during the daytime, sources said.

The missile, under development by DRDO, will be equipped on indigenous INS Arihant-class nuclear-powered submarines of Navy.

India is expected to carry out more tests of the missile before it is ready for being equipped on the nuclear submarines.

At present, only the first nuclear boat INS Arihant is operational for the Navy.

K-4 is one of the two underwater missiles that are being developed by India for its submarine force.

The other one is the over 700-kilometre strike range BO-5.
