What is “Project-75”

• It is a programme by the Indian Navy that entails building six Scorpene-Class attack submarines.
• The programme has been undertaken with transfer of technology from French company Naval Group (formerly known as DCNS) at the Mazagon Dock Limited (MDL).
• The submarines in the P75 Scorpene-Class are powered by the conventional diesel-electric propulsion system.
• The first Scorpene submarine, Kalvari, was commissioned in 2017 and it would go for a normal refit after six years in 2023, during which time the Air-Independent Propulsion (AIP) would be installed.
  
  • AIP technology is being developed by the Defence Research and Development Organisation (DRDO) to provide submarines long-range and extended endurance capabilities undersea.
• Second Scorpene Khanderi was inducted in September 2019.
• The remaining submarines (Vela, Vagir, and Vagsheer) in the series are in advanced stages of manufacturing and trials.
