of power to fire, and it literally tears itself apart with use. The EM
railgun has already been in development and testing for over a decade with
total costs exceeding $500 million for the project.
能量消耗太大。
打一炮，炮架材料都蒸发不少，后坐力也太大损害发射系统。
海军放弃EM railgun了。 |

电磁炮炮弹速度太快，海上开炮时隔得太远空气阻力决定弹道是随机的，根本没法控制
落点。

According to the Wall Street Journal, the Pentagon's Strategic Capabilities
office has allocated $800 million to develop a "defensive capability" for
the gun—i.e. making it shoot with less power for closer ranges—as well as
adapting conventional weapons to fire the tungsten projectile.

如果不求打中呢?
比如发射卫星这样初速度很大, 空中再二次点火
火箭可以少带好多燃料啊

发帖数: 3192 | 22 其实电磁轨道炮并不划算，因为初速度太大，速度越大，阻力成平方增加，大量的能量
都耗在阻力上了。如果用导弹或者巡航导弹，都可以节省不少能量。太空中倒是可以使
用电磁轨道炮。或者近距离防空也可以使用电磁轨道炮，但是弹头可以小很多，能量也
不必那么大了。 |
