India Tests Ballistic Missile for Subs

India successfully tested a new, longer-range submarine-launched ballistic missile (SLBM) on March 24, Indian news outlets reported last month.

The test of the missile, known as the K-4, took place off the southeastern coast in the Bay of Bengal using a submerged pontoon. The two-stage, nuclear-capable missile traveled approximately 3,000 kilometers, the news accounts said.

India did not immediately publicize the missile test. But The Hindu on May 8 quoted officials who were present at the test as calling it “excellent” and saying that they would conduct “many more missions” like it to increase the reliability of the missile.

The K-4 eventually is to be deployed on Indian submarines, the first of which is currently undergoing testing.

Avinash Chander, director-general of India’s Defence Research and Development Organisation (DRDO), said May 13 that India would be conducting a test launch of the K-4 from the INS Arihant “within the next few months.”

The DRDO is the main Indian government entity responsible for developing new, advanced military technologies.

India announced the successful development of a shorter-range SLBM, the K-15, in July 2012 and indicated at that time that the longer-range K-4 was under development. (See ACT, September 2012.)

According to the DRDO, the K-15 has a maximum range of 700 kilometers for a 700-kilogram payload.

Only four other countries—China, France, Russia, and the United States—have the capability to produce SLBMs. Although the United Kingdom deploys such missiles, they are produced in the United States.

India is planning to develop four nuclear submarines in total, and the boats are designed to carry four K-4 missiles or 12 K-15 missiles. New Delhi is planning to deploy the submarines by 2023.
