India’s naval deterrence is set for a significant upgrade with the upcoming S5 class of nuclear-powered ballistic missile submarines (SSBNs). These underwater behemoths, boasting a submerged displacement of a staggering 13,000 tons, will be powered by a revolutionary new reactor – the 190 MW Pressurized Light Water Nuclear Reactor (PWR) – developed indigenously by the Bhabha Atomic Research Centre (BARC).
This marks a substantial leap from the 83 MW reactors currently powering the Arihant-class SSBNs. The new design, according to sources at idrw.org, is complete and awaits funding clearance before construction of a land-based prototype can begin.
The 190 MW PWR promises significant advancements over its predecessor. It will offer not only increased power but also improved efficiency and refinement. A key benefit is the extended refueling interval, with the new reactor requiring replenishment only once every 10 years, significantly enhancing the operational endurance of the S5 submarines.
However, the S5 class is still in the early stages of development. Project approvals are yet to be granted, and construction is not expected to begin before the end of this decade. The first S5 submarine is likely to be inducted into service sometime after 2035.
The arrival of the S5 class will be a major milestone for India’s strategic nuclear program. The increased range and firepower offered by these submarines, coupled with the extended operational periods thanks to the new reactor, will further solidify India’s position as a major naval power.
