In a significant boost to its naval capabilities, the Indian Navy has been offered advanced pump-jet propulsion technology by France for its upcoming next-generation diesel-electric attack submarines under Project 66, and Project 77, which focuses on acquiring nuclear-powered attack submarines (SSNs).
The pump-jet propulsion system, a modern alternative to conventional propellers, is currently in use by France’s Barracuda-class submarines. It reduces the acoustic signature of the submarines, enabling quieter and more stealthy operations. With this technology, India’s submarines could become the quietest in the Indian Ocean Region, providing a strategic advantage in underwater warfare.
Stealth is critical for submarines navigating hostile waters. In addition to reducing operational noise, this cutting-edge technology enhances the maneuverability of submarines, making them more agile in complex underwater environments.
According to a report titled ‘Australia’s Future Submarine: Getting this Key Capability Right’, “a submarine with a pump-jet will always outperform one with a propeller in terms of dived endurance, range, and indiscretion ratio, conferring significant tactical and strategic advantages in various operational scenarios.”
By adopting this technology, India enhances the operational effectiveness of its submarine fleet and establishes itself as a major power in the Indo-Pacific region. France’s offer underscores the strengthening defense ties between the two nations, encompassing joint military exercises and collaborative endeavors in designing, developing, and producing advanced military equipment.
