India's Submarine Deal Finally Moves After Years of Delay
16 Aug
Summary
- Six advanced conventional submarines to be built in India for Rs 70,000 crore.
- German firm TKMS partners with Indian companies for torpedoes and warfare systems.
- Project aims to boost Navy's capabilities amid rising Chinese submarine activity.

India's significant Project 75(I) submarine program, involving the construction of six advanced conventional submarines at an estimated Rs 70,000 crore, is poised for advancement. The proposal is expected to reach the Cabinet Committee on Security soon, potentially unblocking years of negotiation delays.
Primary construction will occur in India through Mazagon Dock Shipbuilders Ltd (MDL) in collaboration with Germany's ThyssenKrupp Marine Systems (TKMS). TKMS is proactively establishing Indian partnerships, including an MoU with VEM Technologies for torpedo development and integration, and a collaboration with CFF Fluid Control for anti-submarine warfare systems.
The project's core objective extends beyond acquiring submarines; it focuses on developing domestic capabilities in construction, maintenance, and design, with an emphasis on technology transfer. The new submarines are anticipated to feature air-independent propulsion for extended submerged operations and advanced weaponry.
This development addresses the Indian Navy's urgent need to enhance its conventional submarine fleet, which faces a shortfall. The delayed project aims to bolster underwater stealth and surveillance, a critical measure given increased Chinese submarine presence in the Indian Ocean. The partnership with TKMS renews a historical link with German submarine technology, now with a strong Make-in-India mandate.
