India Successfully Tests Nuclear-Capable K-4 Missile From INS Arighaat, Adds Teeth To Naval Deterrence

India has successfully conducted a test of a nuclear-capable submarine-launched ballistic missile (SLBM) with a strike range of 3,500 km, according to sources. The trial was carried out from the newly commissioned nuclear-powered submarine, INS Arighaat, off the coast of Visakhapatnam and involved the K-4 missile, a solid-fuelled SLBM.

This marks the first instance of the K-4 missile being tested from INS Arighaat, which was inducted into the Indian Navy in August. Previously, the missile had only been tested from submersible platforms over several years.

India had earlier issued a Notice to Airmen (NOTAM) and a public alert for an intermediate-range missile test, covering a flight corridor of 3,490 km, scheduled between November 27 and 30.

A comprehensive analysis of the test results is currently underway to verify if the missile achieved its intended parameters and objectives, sources added.

The K-4 missile, developed by the Defence Research and Development Organisation (DRDO), is designed to equip India's nuclear-powered submarines, bolstering its maritime deterrence. Nations such as the United States, Russia, and China already possess SLBMs with ranges exceeding 5,000 km.

The 6,000-tonne INS Arighaat is India's latest addition to its fleet of nuclear-powered submarines, enhancing its second-strike capability. The country's first nuclear-powered submarine, INS Arihant, inducted in 2016, is armed with shorter-range K-15 missiles capable of reaching 750 km.

A third submarine in the series, expected to have a displacement of 7,000 tonnes and greater capabilities, is anticipated to be inducted next year. Additionally, last month, the Cabinet Committee on Security (CCS) approved the construction of two more nuclear-powered attack submarines to strengthen India's strategic presence in the Indo-Pacific region.
