China’s first AIP sub breaks records

Issue: 03-2018

China’s first submarine unit using airindependent propulsion (AIP) technology recently broke a number of records set by the Chinese Navy like the longest sailing distance, maximum submergence depth etc. Military commentator Zhang Haixiong disclosed that submarines equipped with AIP technology prolong operation duration underwater to about two or three weeks, indicating the increasing stealth of the submarines. He added that AIP submarines, with higher combat effectiveness, are second only to nuclear submarines.
