由于地球上四分之三的面积是海洋,因此争夺海上优势在军事斗争中至关重要。潜艇作为一种能在水下作战的武器,已愈来愈成为争夺制海权的重要力量。随着潜艇作战威力的日益增强,潜艇自身固有的一些弱点也日渐暴露。其中,远程通信就是极为薄弱的一项。 Since three-quarters of the planet’s area is sea, fighting for maritime advantage is crucial in the military struggle. Submarines, as a weapon capable of under water, have increasingly become an important force in the fight for sea-control. With the growing submarine combat power, some inherent weaknesses of the submarine itself are also increasingly exposed. Among them, long-range communication is a very weak one.
