India successfully test-fired its K-4 submarine-launched ballistic missile (SLBM) from the nuclear-powered submarine INS Arihant in the Bay of Bengal on Tuesday, significantly boosting its sea-based nuclear strike capability.
The missile, capable of hitting targets up to 3,500 km away, was launched off the coast of Vishakhapatnam and is designed to carry a 2.5-ton nuclear warhead. The K-4, commissioned into the Indian Navy on August 29, 2024, is the country’s longest-range sea-launched strategic weapon and is derived from the Agni-III land-based missile, modified for submarine launch.
Experts said the test strengthens India’s nuclear triad, allowing ballistic missile submarines to remain undetected on extended deterrence patrols. The ‘K’ series of missiles is named in tribute to former President APJ Abdul Kalam, a key figure in India’s missile development program.
The successful test marks a milestone in India’s undersea nuclear capabilities and enhances its strategic deterrence posture in the region.
