AIP (Air-Independent Propulsion)

Air-Independent Propulsion (AIP) refers to technologies that allow submarines to operate underwater for extended periods without needing to surface or rely on oxygen from the atmosphere. Traditional submarines use diesel engines that require air, making them vulnerable when submerged. AIP systems, which can include fuel cells or batteries, provide power without needing oxygen, enabling stealthier operations and greater endurance underwater. This capability enhances naval warfare by allowing submarines to remain hidden for longer, thus improving their effectiveness in surveillance and strategic missions.
