Beijing Highlander Digital Technology Co.Ltd(300065) said on the “interactive easy” platform of Shenzhen Stock Exchange on February 24 that the company’s undersea observation network business is mainly the R & D and production of the core component undersea connection box. During the war, the submarine observation network mainly monitors the activities of the surface and underwater combat units along the whole coast, and timely finds and prevents the infiltration of enemy submarines, frogmen, small ships and other equipment. At present, the laying proportion of China’s seabed observation network is low, and the follow-up needs to be rapidly improved.
