Photographs circulating on Chinese social media sites show a Type 927 twin-hulled acoustic surveillance ship berthed at the People’s Liberation Army Navy (PLAN) main South Sea Fleet base at Zhanjiang. The vessel bears the pennant number 780 and appears to be flying a naval ensign, indicating that the ship has most probably entered service. Three are known to have been built, two at the Huangpu shipyard in Guangzhou and one at the Shuangliu shipyard in Wuhan.

Type 927 vessels are twin-hulled, with a displacement of approximately 5,000 tonnes. The ships are 90 meters long and have a beam of 30 meters being completed at a shipyard in Huangpu near Hong Kong that has built SWATH designs for the Chinese navy before. SWATH vessels are both extremely stable and extremely quiet, especially when outfitted with electric motors for propulsion. Their stability and quiet make them especially useful for hydrographic surveying and research utilizing sonar and other sensitive acoustic equipment, and for locating submarines.
