Type 922III
Type 922III was originally planned in 1978, but original design had to be modified to meet the updated requirement. In September 1982, design work was completed and construction begun on December 20, 1982 at Wuchang Shipyard. The ship was originally scheduled to be built by Guangzhou Shipyard International but a decision was made on May 27, 1982 to have it built at Wuchang Shipyard instead. Type 922III was launched on May 20, 1983, and after traveling to Shanghai, begun sea trials on April 17, 1986. Further tests were conducted in Zhoushan from May 28 to June 17, 1986, and in Qingdao and Dalian from July 21 to September 2, 1986. Trials revealed some modification was needed and after such modifications were completed, the ship was formally handed to PLAN as Bei-Jiu (北救, meaning North Rescue in Chinese) 122 in Qingdao on March 31, 1987. Type 922III is armed with twin 37 mm guns and received NATO reporting name Dalang II class.
Type 922IIIA
Type 912IIA is the improvement of earlier Type 912III. The obvious external difference between Type 912IIIA and its predecessor Type 912III is minor and both share the same NATO reporting name Dalang.II class. A total of three ships were built with one serving in each fleet. Type 922IIIA ships in PLAN service are designated by a combination of two Chinese characters followed by three-digit number. The second Chinese character is Jiu (救), meaning rescue in Chinese, because these ships are rescue and salvage ships. The first Chinese character denotes which fleet the ship is service with, with East (Dong, 东) for East Sea Fleet, North (Bei, 北) for North Sea Fleet, and South (Nan, 南) for South Sea Fleet. The pennant numbers have changed or some units due to the change of Chinese naval ships naming convention.
