20世纪初从英国的“无畏”舰建成服役开始,改变海战模式的时代开始了,美国、德国、意大利、日本等国纷纷仿效英国“无畏”号的设计,开始了新一轮战列舰的建造。很短的几年里,当时的世界海军强国都有了“无畏”舰为模式的新型战列舰,这些战列舰的主炮其口径在280～305毫米之间,其中的代表包括德国的“拿骚”级、美国的“南卡罗来纳”级。 At the beginning of the 20th century, the era of naval warfare began with the inauguration of the British “dauntless” ship. The United States, Germany, Italy, Japan and other countries all followed the example of the British “dauntless” design and started a new round Battleship construction. In a very short span of a few years, the world naval powers at that time had new models of “dauntless” warships. The main guns of these battleships were between 280 and 305 millimeters in diameter, and their representatives included the German “ Nassau ”level, the United States “ South Carolina ”level.
