Project history: The first nuclear-powered vessels and the first submarines designed and built in China, by the Huludao Shipyard. Considerable help with the powerplant was received from West Germany. They have an Albacore-type teardrop hull. Changzheng 401 underwent prolonged trials, and construction of further units was delayed by powerplant problems. The last three units of the class are longer than the original boats.
Modernizations: late 1990s, all: + new anechoic plating, ability to use wire-guided Yu-6 torpedoes
late 2000s, all survived: sonars were replaced by H/SQ2-262B sonar suite
Naval service: No significant events.
