冷战结束以后,世界各国国防开支普遍出现了大幅缩减,但是我国周边各国却没有受到影响,国防开支普遍呈现增长态势,开始逐步加强本国军事力量的建设。其中,潜艇由于具有隐蔽性好、攻击性强等特点,尤其受到周边各国的重视,普遍将其作为重点采购和研制的装备之一,不断加强本国的水下力量建设。 Since the end of the Cold War, there has been a drastic reduction in the national defense expenditures of various countries in the world. However, the countries in our neighboring countries have not been affected. The national defense expenditures have generally shown a growth trend, and the construction of their own military forces has begun to be gradually strengthened. Among them, the submarine has the characteristics of good covertness and aggressiveness, and is especially valued by the neighboring countries. It is generally regarded as one of the key procurement and research and development equipment, and the submarine constantly strengthens its own submarine forces.
