Air-independent propulsion
PROPULSION SYSTEM FOR SUBMARINES WHICH OPERATES WITHOUT ACCESS TO ATMOSPHERIC OXYGEN
Air Independent Propulsion; Air-Independent Propulsion; Air independent propulsion; Air-Independent Power; Air-independent power; Air-independant propulsion
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen (by surfacing or using a snorkel). AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
