India's S5 SSBN to Armed with 12 SLBM Launch Tubes, K5 Missile, and 190 MW Reactor

India's naval strength is set for a significant boost with the development of its next-generation ballistic missile submarines (SSBNs), the S5 class.

These submarines are poised to dramatically enhance the country's nuclear deterrence capabilities, marking a substantial leap forward in firepower and technological sophistication.

The S5 class SSBNs are anticipated to feature a remarkable 12 or more launch tubes, a considerable upgrade from the current Arihant-class submarines, which possess only 4.

This expanded capacity will enable India to deploy a more formidable arsenal of K5 and K5 SLBMs, which are currently in the development phase. These missiles are designed to carry multiple nuclear warheads across vast distances, providing India with a potent and credible nuclear deterrent.

Furthermore, the S5 class submarines will incorporate a series of technological advancements to enhance their stealth and survivability.

Equipped with a new 190MW pressurized light-water reactor (PWR) fueled with enriched uranium, these submarines will boast a longer range and a quieter signature, making them significantly more difficult for adversaries to detect and track.

The increased size and advanced propulsion systems of the S5 class submarines will grant them greater operational freedom in the vast expanses of the Indian Ocean and Pacific Ocean regions.

This will ensure that India maintains its nuclear triad, consisting of land-based, sea-based, and air-based nuclear delivery systems, which is considered vital for a robust and credible nuclear deterrent.

While the S4 and S4 Star submarines are already in the final stages of fitment, the S5 design phase is nearing completion, and the program is expected to receive official sanction soon.

This ambitious undertaking underscores India's commitment to maintaining a credible and effective nuclear deterrent in an increasingly complex geopolitical landscape.

Sir, 6 SSBNs would allow for a continuous patrol of 1 boat, with a second boat occasionally available. In order to get 3 boats on near-continuous patrol, you'd need 10 boats. The rough rule is 3.5 to 1.

wow! Our defense budgets even if they double to say $150B by 2035 (which is also a stretch) will not be enough for 10 SSBNs! Maybe by 2050 we may get there...National security is expensive, just ask the Americans and the Chinese...

China has the largest navy in the world. We still have a long way to go before we can challenge them.

That Chinese Navy manned by newly trained sailors and admirals has no experience. They are comfortable being in China Sea and not any further. For them to come to Indian Ocean and leave China Sea open for retreat is unthinkable. They would be wise to not travel to come 4000km into Indian Ocean and face Indian Navy and shore and coastal firing squad of India. No they won’t come….

That can be said for the Indian Navy as well. Our experience is limited to dealing with the Pakis, most of it on borrowed technology from the Brits and the Soviets.

Have a huge experience, in 1965, 1971 and 1999. Even few weeks back Indian Navy intervened quickly to prevent hijacking near Somalia coast.

China watch out. India is ready to take you on.
