“鱼儿”上钩,“诱饵”逃窜潜艇之间的“斗法”在第一次世界大战时就开始了,但由于当时的装备技术水平不高,潜艇无法攻击水中潜航的潜艇。因此双方都采用诱骗战术,设法使对方潜艇浮上水面,然后像对付水面舰艇那样进行攻击。 “Fish” hooked, “bait” to escape the “law” between submarines began in World War I, but due to the equipment was not high level of technology, submarines can not attack submarines submerged in water. Therefore, both sides resort to trickery tactics to try to make the other submarine surfaced and then attacked like a surface ship.
