A new open-source investigation has revealed that China recently launched their third anti-submarine detection ship at a shipbuilding facility in Wuhan, augmenting Beijing's ability to detect submarines.

The ship is most likely a SWATH design, or Small Waterplane-Area Twin Hull. The twin-hull design is both very stable, even at high speeds or in rough seas, and is also known for being very quiet, a useful quality to have for a ship intended to use sonar and other acoustic listening devices to detect submarines.
