Type 927 acoustic surveillance ship is a type of vessel used by the People’s Liberation Army Navy. There are three known Type 927 ships,[1] plus one predecessor Ruili No.10, which is slightly larger than Type 927 ships, and it was used to test onboard systems such as sonars for the three Type 927 ships.[2] The first Type 927 ship was launched around June 2017 in Guangzhou.[3][4] Type 927 has received NATO reporting name Dongjian class,[5][6][7] 东监 in Chinese, meaning East Surveillance, because the West first observed it performing acoustic surveillance missions in East China Sea.

Characteristics

Type 927 vessels are twin-hulled, with a displacement of approximately 5,000 tonnes.[1] The ships are 90 meters long and have a beam of 30 meters.[3]
