1959年,在美国海军“乔治·华盛顿”号核潜艇成功地发射了射程为2200公里的北极星A-1导弹之后,导弹核潜艇开始正式为海军装备使用。目前,美国海军已拥有多艘北极星、海神导弹核潜艇。在建造中的三叉戟导弹核潜艇,其射程已达到11000公里。导弹核潜艇在军事上的威胁作用是很大的。为了适应现代战争的需要,核潜艇上的通信系统十分重要。 In 1959, after the U.S. Navy “George Washington” nuclear submarine successfully launched a Polaris A-1 missile with a range of 2,200 kilometers, the missile submarine was officially used for naval equipment. At present, the United States Navy already has many Polaris and Poseidon missile submarines. The Trident missile submarine under construction has a range of 11,000 kilometers. The role of missile submarines in the military threat is great. In order to meet the needs of the modern warfare, the communication system on nuclear submarines is very important.
