**India’s Nuclear Doctrine: A Strong Stance on Deterrence**
India’s nuclear doctrine, established in 2003, asserts that any nuclear retaliation to a first strike will be substantial and aimed at causing unacceptable damage. As one of the few nuclear powers alongside China, India has committed to a ‘No First Use’ (NFU) policy, clearly stating it will not initiate a nuclear attack. This doctrine serves as a stern warning: any nuclear aggression against India will result in a devastating response.
For this deterrent threat to be credible, India must possess what experts refer to as an assured second-strike capability. This involves maintaining nuclear weapons in highly secure locations that are nearly impossible to target in an enemy’s initial strike. One of the most effective ways to achieve this is through underwater platforms.
Recently, India is believed to have conducted a covert test of the K-4 submarine-launched ballistic missile (SLBM). Although the government has not officially confirmed the test, it represents significant progress in India’s strategic deterrence capabilities and its ability to execute a second strike. This marks the second test of the 3,500-km range missile from a submarine, with the first launch reportedly occurring in late 2024. The specific submarine involved in these tests remains undisclosed, as India currently operates two nuclear submarines, INS Arihant and INS Arighaat, with two additional vessels undergoing sea trials. Consistent with its tradition, India has not publicly acknowledged these launches.
**The Importance of SSBNs in India’s Defense Strategy**
To grasp the significance of these test launches, it is essential to understand the role of SSBNs (Ship, Submersible, Ballistic, Nuclear). These submarines are the epitome of stealth, capable of evading detection unlike land-based launchers or bomber aircraft. An SSBN can remain submerged for extended periods, powered by a reactor that can sustain operations for years. The submarine’s endurance is primarily limited by the crew’s supplies and not by its technology.
This capability ensures that even in the event of a catastrophic nuclear strike that could potentially eliminate India’s land-based silos and airbases, an SSBN lurking in the depths of the ocean can execute a retaliatory strike, inflicting massive and unacceptable damage on the aggressor. This deterrent effectively makes any first strike against India a perilous gamble.
Currently, India has two operational SSBNs: INS Arihant, commissioned in 2016, and INS Arighaat, which entered service in 2024. A third vessel, INS Aridhaman, is undergoing trials and is expected to be commissioned soon, with a fourth SSBN planned for the near future. The addition of these submarines will enhance India’s nuclear deterrent capabilities significantly.
In conclusion, India’s commitment to its NFU policy and the development of its SSBN fleet underscores its strategic approach to nuclear deterrence. As India continues to enhance its capabilities, the implications for regional security and stability remain profound.

**What is India’s No First Use policy?**
India’s No First Use policy means that it will not be the first to launch a nuclear weapon in a conflict, ensuring that any nuclear response will only occur after an initial nuclear attack against it.
