India’s upcoming generation of ballistic missile submarines (SSBNs), the S5 class, is set to significantly bolster the country’s nuclear deterrence capabilities. These submarines will feature a substantial increase in the number of launch tubes, accommodating a larger arsenal of submarine-launched ballistic missiles (SLBMs).Both S4 and S4 Star submarines are already on outer docks getting final fitments with S5 design phase nearing end, program is set to get official sanction soon.
The S5 class SSBNs are expected to have 12 or more launch tubes, a significant upgrade from the current Arihant-class submarines, which have only 12 tubes. This increased capacity will allow India to deploy a larger number of K5 and K5 SLBMs, which are currently under development. These missiles are designed to carry multiple nuclear warheads over long distances, providing India with a potent nuclear deterrent.
The S5 class submarines will also feature a number 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 have a longer range and a quieter signature, making it more difficult for adversaries to detect and track them.
With their increased size and advanced propulsion systems, the S5 class submarines will be able to operate more freely 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.
The S5 class SSBNs represent a major investment in India’s national security. These submarines will provide a credible nuclear deterrent, ensuring that India’s adversaries think twice before contemplating aggression. By maintaining a strong nuclear arsenal, India can safeguard its sovereignty and territorial integrity.
