DRDO and L&T tie-up for AIP System in Indian Navy


DRDO and L&T tie-up for AIP System in Indian Navy

Larsen & Toubro (L&T) and the Defence Research and Development Organisation (DRDO) have formed a partnership to create an Indigenous Air Independent Propulsion (AIP) System for the submarines in the Indian Navy. Under this collaboration, two AIP System Modules are being developed for the Kalvari Class submarines. These modules, comprising fuel cell-based Energy Modules (EMs), aim to generate power and produce hydrogen as needed. This innovative approach eliminates the requirement to store hydrogen onboard, thereby addressing safety issues associated with carrying hydrogen on submarines.

About the Agreement

  • L&T is the recipient of the Transfer of Technology (ToT) for this Defence Research and Development Organisation (DRDO)-developed system. Through the integration of these modules, India will establish itself among a select group of nations with the capability to develop indigenous fuel cell-based AIP technology.
  • This advancement will significantly enhance the endurance of conventional submarines. Moreover, this eco-friendly technology produces clean water as a by-product, contributing to environmental sustainability.
  • L&T, as the primary industry partner, has a longstanding collaboration with DRDO and has been entrusted with the Transfer of Technology for this AIP System. The manufacturing, integration, and factory acceptance trials of the Energy Modules (EMs) will take place at L&T’s AM Naik Heavy Engineering Complex in Surat, ensuring adherence to high-quality standards and timely delivery.
  • If this project is successfully implemented, it has the potential to result in additional orders for AIP Systems not only for the remaining Kalvari Class submarines but also for other countries that operate Scorpene class submarines, opening up possibilities for export opportunities.

Important takeaways for all competitive exams: 

  • DRDO Date founded: 1958;
  • DRDO Headquarters: DRDO Bhavan, New Delhi;
  • DRDO Chairman: Sameer V Kamath.
