在近代海战中,潜艇是一种有成效的舰种。在一次大战初期,曾有一艘德国潜艇取得在一小时之内连续击沉三艘英国大型装甲巡洋舰的战例。在二次大战中,被德国击沉的商船中近百分之七十是由潜艇击沉的。但是,当时的潜艇是用蓄电池作电源,不仅航速慢(最大时速只有四十公里),而且全速航行时只能跑一个小时左右,然后就需浮出水面利用柴油发电机进行充电;还需要经常浮上水面进行换气。这样频繁地上上下下极易暴露,对潜艇的战术性能影
In modern naval battle, the submarine is a fruitful ship. In the early days of World War I, there was a German submarine battle that resulted in the continuous sinking of three large British armored cruisers within an hour. Nearly 70% of the merchant ships sunk by Germany in World War II were sunk by submarines. However, the submarine at the time used batteries as its power source not only for slow speed (maximum speed of only 40 km / h) but also for an hour or so at full speed and then surfaced and charged with a diesel generator; it also required frequent Float on the surface for ventilation. This frequently up and down easily exposed, the tactical performance of the submarine shadow
