Type 065 Jiangnan-class Frigates
The Type 065 Jiangnan [Kiangnan]-class frigates [also designated destroyer escorts] were built in China based on a modified Riga-class design obtained from the Soviet Union, using diesel rather than steam turbine propulsion.
In 1962, the No. 701 Institute began the research and design of the Type 65 frigate. The first ship was built in 1963 in the Guangzhou shipyard. A second frigate was built two years later, and both ships were delivered to the PLAN in 1966. Western sources diverge as to exactly which shipyards were engaged in this project.
