“水下鼹鼠”何以逃避第二次世界大战爆发后,潜伏在大西洋运输线上的德国潜艇,恶狼般地频频出击“扑食”盟国的军舰与商船。开始,由于盟国海军的反潜力量势单力薄,因此难以抵御德潜艇凌厉的攻势。而盟军飞机当时完全依靠飞行员的目视搜索;水面舰艇尽管装设了声纳,但由于技术不过关,作用距离太短,对水下噪声分辨率低,因而难以发现德潜艇,致使己方被击沉的运输船舶越来越多。为此,盟军最高统帅部着了急,下令一定要把这些“水下鼹鼠”一网打尽。可 “Underwater Mole ” Why avoid the German submarine lurking in the Atlantic transport line after the outbreak of World War II, wickedly attacked the warships and merchant ships in the Allied nations. In the beginning, the anti-submarine forces of the Allied Navy were struggling to withstand the fierce attacks of the German submarine because of their weak anti-submarine forces. Allied aircraft were completely dependent on the pilot’s visual search at that time; although the surface ships were equipped with sonars, they were difficult to find German submarines due to the shortcomings of technology, short distance of action and low resolution of underwater noise Ship sinking more and more ships. To this end, the supreme commander of the Allied forces took a hurry and ordered that these “underwater moles” must be brought to a close. can
