Larsen & Toubro (L&T) Defence, led by Executive Vice President and Head Arun Ramchandani, has confirmed a key aspect of its joint bid with Navantia for the Indian Navy’s Project 75I tender. The bid proposes the S-80 Plus class submarines, with a significant focus on maximizing local Indian content.

If their bid is chosen, L&T-Navantia promises that nearly 60% of the components used in the S-80 Plus submarines constructed for India will be sourced locally. This signifies a substantial commitment to India’s “Make in India” initiative, promoting domestic manufacturing and technological expertise.

The L&T-Navantia team faces competition from Germany’s TKMS, offering its U-212 submarine with its Indian Partner Mazagon Dock Shipbuilders Limited (MDL) from India. 

The S-80 Plus submarine is designed to be a frontrunner in the conventional submarine market. Key features include:

  • Advanced Combat System: Ensuring superior offensive and defensive capabilities.
  • Enhanced Stealth: The latest generation Air-Independent Propulsion (AIP) system significantly reduces detectability by extending the submerged range and reducing reliance on surfacing for battery recharge.
  • Bioethanol-powered AIP: This innovative system utilizes bioethanol to generate hydrogen for electricity production, minimizing noise and emissions.
  • High Survivability: The S-80 Plus boasts a robust design, meeting the most demanding operational requirements.
