The P-75 I project (Project 75 India) is a follow-on project to Project 75 of the Indian Navy, which involved the construction of six Scorpene-class submarines. P-75 I aims to acquire a new class of diesel-electric submarines equipped with Air Independent Propulsion (AIP) technology to increase their underwater endurance.

– P-75 I is part of India’s plan to modernize its submarine fleet.
– The project emphasizes indigenous construction under the ‘Make in India’ initiative, often involving collaboration with foreign partners providing technology.

Diesel-electric submarines are also known as conventional submarines. AIP technology allows these submarines to operate submerged for longer periods than traditional diesel-electric submarines, reducing the need to surface or snorkel for air to recharge batteries.
