China Shipbuilding Industry Corporation
In 1966, PLAN decided to indigenously develop a new generation of large torpedo boat that is armed with four torpedo tubes. The large boat would have better sea keep capability than its smaller predecessors and because it is more heavily armed, less will be needed to achieve the same result in comparison when its smaller predecessors were deployed. The 701st Research Institute of the China Shipbuilding Industry Corporation (CSIC, known as Warship Research Academy at the time) was assigned as the designer, and Wuzhou 449th Factory, the predecessor of China Guijiang Shipbuilding Co., Ltd. (中船桂江造船有限公司) was assigned to build the first unit. Construction begun in 1971 and the boat was launched in 1974, and turned over to PLAN in 1976, and is designated as Type 027.
