近年来,韩日两国基于自身利益的现实需要,大力强化潜艇力量建设。在日本加紧改进部署亲潮级潜艇的同时,韩国潜艇力量也得到了快速发展。2007年6月13日下午,韩国海军第2艘214级“郑地”号潜艇,在蔚山现代重工集团举行了隆重的下水仪式。韩军方表示,该潜艇将与KDX-II型“宙斯盾”驱逐舰一起,构成韩国的核心战斗力,“以抗衡日益扩张的日本海上力量”。 In recent years, both South Korea and Japan have greatly strengthened the building of submarine forces based on the actual needs of their own interests. While Japan has stepped up its efforts to improve the deployment of the pro-submarine submarines, the strength of the South Korean submarines has also been rapidly developed. On the afternoon of June 13, 2007, the 2nd Navy 214 “Submarine” submarine of South Korea Navy held a grand launching ceremony at Hyundai Heavy Industries Group in Ulsan. South Korean military said the submarine will be together with the KDX-II “Aegis” destroyers to form Korea's core combat capability, “to counter the ever-expanding Japanese maritime power.”
