The China Shipbuilding and Offshore International Corporation (CSOC) used the 2017 IDEX show in Abu Dhabi to reveal its new MSS-01 Mobile Submarine Simulator.
The simulator, which also serves as a decoy, is in service with the Chinese navy according to a company official.
The MSS-1 is described as a "self-propelled underwater acoustic countermeasure designed for ASW [anti-submarine warfare] engagement and training scenarios". It uses "high fidelity simulation of submarine radiated noise" and "echo repeat while receiving" it can deceive "sonar, acoustic homing torpedoes, and wire-guided acoustic homing torpedoes".
With a length of 5,500 mm, a 533.4 mm diameter, and a weight of 1,100 kg, it is launched from a torpedo tube and can be recovered when in training mode. It has a speed of 10-15 kt, an operating depth of 10-300 m, and an endurance of 100 minutes at 10 kt or 45 minutes at 15 kt.
