任何国家的海军,在确定他的作战要求时,或者在为他的舰艇确定一种新的作战思想时,都应该注童于舰艇的综合性防御,而不应该依赖于各个独立的系统,虽然用这些独立的系统也能装备成较好的舰艇。当人们考察一下使用中的各种舰艇,就会发现情形并非如此,例如英国皇家海军的无敌级通长甲板巡洋舰,根本没有任何近距离防御系统——既没有轻型火炮,也没有像“密集阵”和“守门员”这样的火炮系统,甚至连“海狼”这样有名气的反导弹导弹系统也没有。无敌级通长甲板巡洋舰仅有的防御系统是中程“海标枪”(实际上它没有真正的反掠海导弹的能力)、海上鹞式垂直起落战斗机和乌鸦座箔条散布系统。有些国家海军则仅选用火炮来 The navy of any country should, when determining his operational requirements or when determining a new operational concept for his ship, should inject a comprehensive defense of the ship instead of relying on separate systems. With these independent systems can also be equipped with better ships. When people look at the various types of ships in use, this is not the case. For example, the British Royal Navy’s invincible class long deck cruisers, there is no any short-range defensive system - neither light artillery, “And” goalkeeper “such artillery systems, and even the famous” Sea Wolf “anti-missile missile system does not.

In some countries, the Navy only used artillery
