DRDO, L&T join hands for AIP system for Navy's 'Kalvari' class submarines
Larsen and Toubro and DRDO have signed a contract for the realisation of two Air Independent Propulsion (AIP) system modules for 'Kalvari' class submarines of the Indian Navy.
AIP system is a unique one that generates hydrogen on demand thereby obviating the need for carrying hydrogen onboard which is a major safety concern for a submarine. Image: Twitter/@indiannavy.
