INS Aridhaman, India's third nuclear-powered ballistic missile submarine, commissioned into naval fleet

The concept of a nuclear triad involves the capability to launch nuclear weapons from land, air, and sea platforms. For India, the development of SSBNs is critical to establishing a credible and survivable second-strike capability, enhancing its nuclear deterrence posture. Such submarines provide an assured retaliation capacity, even if land-based or air-based assets are neutralized in a first strike, thus contributing to strategic stability. INS Aridhaman joins INS Arihant and INS Arighat in India's growing fleet of indigenous SSBNs. This commissioning, alongside the launch of a stealth frigate and a cavitation tunnel facility, marks a significant milestone in India's self-reliance in defence manufacturing and maritime strategic capabilities. It demonstrates India's commitment to modernizing its armed forces and projecting power in the Indian Ocean region. This development is of paramount importance for national security and international relations syllabi. It signifies India's rise as a major maritime power, reinforces its nuclear deterrence doctrine of 'no first use' but 'assured retaliation', and impacts the balance of power in the Indo-Pacific. The indigenous development also highlights advancements in India's defence technology and engineering capabilities.
