During National Security Adviser Ajit Doval’s recent visit to Paris, crucial discussions took place between Doval and top French officials regarding strategic defense cooperation. Among the key topics was France’s offer to assist India in the development of two nuclear-powered attack submarines (SSNs) for the Indian Navy. This cooperation could mark a significant leap forward in India’s naval capabilities, as France has proposed sharing Pump jet propulsion technology and other non-nuclear technologies from its Barracuda-class SSN submarine program.
Sources familiar with the talks revealed that France’s offer goes beyond just technical assistance. Paris has expressed its willingness to cooperate on a range of submarine technologies, including the Pump jet propulsion system—a technology that enhances the stealth and efficiency of nuclear submarines. While it remains unclear if France has formally offered the complete design of its Barracuda-class submarines, all non-nuclear technologies integrated into these advanced vessels are reportedly on the table.
The Barracuda-class nuclear-powered attack submarine (SSN), which is known for its low noise signature and advanced combat systems, is considered one of the most modern attack submarines in service. Its Pump jet propulsion provides a quieter, more efficient alternative to traditional propellers, making it a highly desirable technology for any modern submarine fleet. The Indian Navy, which plans to develop at least six SSNs, stands to benefit immensely from this offer, as it would significantly accelerate the timeline for inducting these submarines into service.
India’s Warship Design Bureau (WDB) has already made substantial progress in the design of a nuclear-powered attack submarine. The WDB’s finalized design includes provisions for incorporating Pump jet propulsion, which is critical for enhancing stealth and combat capability in undersea operations.
In addition to the design progress, several Indian defense firms have already tested small-scale models of the Pump jet propulsion system. While these trials have shown promising results, scaling up the technology for full operational use may require more time. The development of a fully indigenous Pump jet system involves overcoming various engineering challenges, and Indian companies are currently in the trial-and-error phase to refine and optimize the technology.
Given the time required to perfect this system domestically, the Indian Navy is reportedly considering a hybrid approach. The first two SSNs of the planned six-submarine program could incorporate French Pump jet propulsion technology, while the remaining four submarines would feature an indigenous propulsion system once the technology is matured and tested.
While France’s offer provides a significant boost to the Indian Navy’s SSN program, it is also an opportunity for Indian companies to advance their own technological capabilities. With India keen on developing indigenous defense solutions, the collaboration could allow for the transfer of critical technologies while fostering local development of advanced submarine systems.
