In the pursuit of bolstering India’s naval capabilities, Larsen & Toubro (L&T) Defence, under the guidance of Executive Vice President Arun Ramchandani, unveils a pivotal aspect of its bid alongside Navantia for Project 75I. This joint endeavor proposes the deployment of the S-80 Plus class submarines, emphasizing the integration of locally sourced components.

L&T-Navantia’s bid pledges that approximately 60% of the components utilized in constructing the S-80 Plus submarines for India will be procured domestically. This steadfast dedication aligns with India’s “Make in India” initiative, championing indigenous production and technological advancement.

The formidable bid faces competition from Germany’s TKMS, presenting the U-212 submarine in collaboration with Indian Partner Mazagon Dock Shipbuilders Limited (MDL).


Pioneering Features of the S-80 Plus Submarines

  1. Advanced Combat System: Equipped with state-of-the-art technology, the S-80 Plus submarines ensure unmatched offensive and defensive capabilities, enhancing the Indian Navy’s operational prowess.
  2. Enhanced Stealth: Leveraging the latest generation Air-Independent Propulsion (AIP) system, these submarines significantly diminish detectability by extending submerged range and minimizing the need for surfacing to recharge batteries.
  3. Bioethanol-powered AIP: Embracing innovation, this groundbreaking system harnesses bioethanol to produce hydrogen for electricity generation, resulting in reduced noise emissions and environmental impact.
  4. High Survivability: Engineered to meet stringent operational requirements, the S-80 Plus submarines boast a robust design, ensuring resilience in challenging maritime environments.

The integration of high indigenous content not only fosters self-reliance but also strengthens India’s maritime capabilities, offering enhanced security and operational flexibility. Moreover, collaboration with Navantia underscores India’s commitment to fostering global partnerships for technological advancement and defense cooperation.
