As part of the East China Sea Fleet, Submarine 330 is the first of a new generation of Chinese developed submarines. The primary features of this “new concept power” submarine include low noise level, long submerge time, advanced power systems and cutting edge weapons systems. During a recent trial trip in the northern seas under extreme low temperature conditions, the crew collected a large amount of data on the atmospheric variation patterns of the new cabin, the maneuver margin of the new power system and the physiological tolerance of the crew. The new submarine fleet is introducing new tactics focusing on concealment, breaking through a destroyer fleet, and combating air anti-submarine forces.
