DRDO Begins Preliminary Study on Development of Indigenous Conventional Submarines

Project-76: Indigenous Submarine Development for Indian Navy

The Defence Research and Development Organisation (DRDO) has initiated a study for the design and construction of India’s first indigenous diesel-electric attack submarines under Project-76.

Project Overview

• Goal: To design and build 12 indigenous diesel-electric attack submarines.
• Advancements: Integration of Air-Independent Propulsion (AIP), lithium-ion batteries, and indigenous weapon control systems.
• Submarine Features: A submerged displacement of 3,000 tons, offering enhanced underwater endurance and capabilities.
• Timeline: Prototype construction is targeted for 2028.
• Significance: Reduced reliance on foreign technology, enhancing India’s self-sufficiency in submarine production.

Development Background

• Successor: The new class of submarines will replace the Sindhughosh class, with improvements in operational performance.
• Inspiration: Draws on lessons from previous projects like Project-75 (French technology) and Project-75I (German/Spanish collaborations).
