Submarine Proliferation Resource Collection

Save to My Resources

The NTI Submarine Proliferation Resource Collection details the submarine capabilities and import/export behavior of several representative countries around the world. The collection focuses on technological improvements to global submarine fleets, such as the spread of nuclear propulsion and Air Independent Propulsion (AIP) technologies, which increase the capability of submarines to deliver weapons of mass destruction (WMD). Additionally, the collection tracks conventional submarine proliferation in potential global flashpoints, particularly the Middle East, South Asia, and Southeast Asia.

Air Independent Propulsion Technology (AIP)
Air Independent Propulsion Technology (AIP): A propulsion system that uses liquid (or compressed) oxygen or hydrogen fuel cells, thereby allowing submarines to stay submerged for longer periods without the need for external sources of oxygen. This increased endurance also increases a submarine’s survivability.
WMD (weapons of mass destruction)
WMD: Typically refers to nuclear, biological, or chemical weapons, though there is some debate as to whether chemical weapons qualify as weapons of “mass destruction.”
