The Chinese submarine with the hull number 201 is a Chinese dieselâÂÂelectric auxiliary submarine. It is used to test systems and technologies, including test launching ballistic missiles (SLBM). 201 is the sole member of its class, designated Type 032 (NATO reporting name: Qing).
201 commissioned into the People's Liberation Army Navy (PLAN) in 2012; the previous SLBM testbed, a Golf-class submarine (Type 031), subsequently decommissioned in 2013. It participated in testing the JL-2 SLBM. 201 made the first three JL-3 test launches starting in 2018.
201 resembles an enlarged Type 039A submarine, with bow-mounted retractable diving planes, instead of sail-mounted. The sail is disproportionately long, and extends below the keel like the Golf-class; at least one ballistic missile launch tube is fitted at the rear of the sail. In 2017, the height of the rear sail was increased, likely to support the larger JL-3.
