France has shown a keen interest in collaborating with India on its ambitious plan to manufacture three advanced nuclear attack submarines for the Indian Navy. As part of this collaboration, France has offered India non-nuclear systems and subsystems from its own SSN (nuclear attack submarine) program.

Talks are currently underway at the National Security Advisor (NSA) level, with Ajit Doval leading the discussions on the nuclear submarine cooperation between India and France. One of the key components being discussed is the pump-jets propulsor, which holds great importance for submarine operations.

The Indian Navy has expressed its requirement for pump-jets propulsors, which are crucial and often sensitive components of submarines. These propulsors are essential for the propulsion, manoeuvrability, and stealth capabilities of submarines. Pump jets, with their unique advantages, are being considered for use in India’s three advanced nuclear attack submarines currently under development. To fulfil this requirement, India is likely to approach France for the co-development of the pump-jets propulsor for the program.

Insiders familiar with the matter have revealed that the Indian SSN (nuclear attack submarine) will incorporate a pump-jets propulsor, and each submarine’s design will be specifically customized to optimize efficiency. This customization will ensure that the propulsor aligns with the specific requirements of the Indian Navy’s advanced nuclear attack submarine program. The collaboration between India and France will involve the co-development of the pump-jets propulsor based on French technology, enabling India to leverage the expertise and experience of the French submarine program.

In addition to the advanced nuclear attack submarine program, the Indian Navy is exploring the inclusion of pump-jets propulsors in its planned 3000-ton, 12 Diesel-Conventional submarine project. The use of pump-jets propulsors in these submarines would enhance their manoeuvrability, reduce noise signatures, and improve overall operational capabilities.
