The 2^nd China International Import Expo opened in Shanghai on November 5. The “Deep-Sea Warrior” manned submersible, which is mainly developed by China Ship Scientific Research Center, has participated in the China International Import Expo and demonstrated China's ability to independently develop deep sea equipment.

"Deep-Sea Warrior" manned submersible first adopts the domestic developed ultra-high pressure sea water pump and a large depth, high specific energy, large capacity oil filled lithium battery and battery management system, breaking through a series of key technologies such as low-noise thruster, hydraulic source, buoyancy material, manipulator, deep sea lighting and high-resolution shooting. The domestic equipment such as manned cabin, underwater acoustic communication, Doppler velocimeter, etchas advanced performance and stable technical status, and the localization rate reaches 95%.
