The INS Arighaat, commissioned earlier this year, represents a significant enhancement over its predecessor, INS Arihant, with improved propulsion systems and the ability to carry a mix of K-15 SLBMs, with ranges up to 750 kilometers, and the more advanced K-4 SLBMs. Each K-4 missile is capable of carrying a nuclear warhead, enabling India to sustain credible deterrence even under the most challenging conditions. Such capabilities are vital in maintaining a strategic balance and ensuring national security amid regional tensions.
The INS Arighaat operates under the Strategic Forces Command, tasked with overseeing India's nuclear arsenal. It joins the ranks of submarines equipped with nuclear-capable missile systems, a technology mastered by only a handful of nations, including the United States, Russia, and China. The submarine's nuclear propulsion system allows for prolonged underwater operations, offering stealth advantages over conventional diesel-electric counterparts.
This development comes as part of India’s broader strategy to bolster its defense capabilities. Over the years, the country has invested significantly in modernizing its armed forces and developing indigenous technologies. The K-4 missile test and the commissioning of the INS Arighaat reflect the fruits of these efforts, showcasing the collaboration between the Navy and the Defence Research and Development Organisation (DRDO). The integration of such advanced systems is expected to enhance India’s position as a regional power and contribute to global strategic stability.
