In a significant boost to its nuclear deterrence posture, India has successfully test-fired the K-4 submarine-launched ballistic missile (SLBM) from the depths of the Bay of Bengal using the newly commissioned nuclear-powered submarine INS Arighaat. This development, confirmed by defense sources, marks a pivotal moment in the country’s defense capabilities, further establishing its sea-based nuclear triad.
The K-4 missile can reach targets up to 3,500 kilometers away and is a cornerstone of India’s strategic arsenal, intended to enhance the nation’s second-strike capability. Launched from INS Arighaat, the missile’s test signifies technological prowess and the operational readiness of India’s indigenous nuclear submarine fleet, which now includes two vessels capable of stealthy underwater launches.
The test was conducted in the early hours of November 27th, with the missile emerging from underwater to travel its designated trajectory, showcasing the sophisticated launch and guidance systems. The Indian Navy, under the Strategic Forces Command, oversaw the operation, emphasizing the integration of nuclear technology with naval strategy.

Strategic Implications
The successful test launch reaffirms India’s commitment to a “no first use” policy while bolstering its deterrence against potential nuclear threats. The K-4 missile, which can carry nuclear warheads, provides India with the strategic depth to respond effectively to any aggression, thereby contributing significantly to regional stability.
Technological Milestone
INS Arighaat, an advanced iteration of the Arihant-class submarines, boasts several technological upgrades over its predecessor, INS Arihant. Equipped with four vertical launch tubes, each capable of holding three K-15 missiles or one K-4 missile, the submarine represents a leap in India’s maritime nuclear capabilities. The K-4’s design features include the ability to perform three-dimensional maneuvers in flight, aimed at evading missile defense systems, illustrating India’s advancements in missile technology.
Future Prospects
The successful deployment of the K-4 missile from INS Arighaat is seen as a precursor to the operationalization of subsequent Arihant-class submarines. With two more in different stages of construction, India is set to expand its underwater nuclear deterrent force significantly. This strategic development comes at a time when the geopolitical landscape in South Asia and the Indian Ocean Region remains dynamic, with India seeking to balance the presence of other naval powers.
