可恶的美国人

High-speed camera image of the Office of Naval Research Electromagnetic Railgun located at the Naval Surface Warfare Center Dahlgren Division on December 10, 2010, firing a world-record setting 33 mega-joule shot, breaking the previous record established Jan. 31, 2008. The railgun is a long-range, high-energy gun launch system that uses electricity rather than gunpowder or rocket motors to launch projectiles capable of striking a target at a range of more than 200 nautical miles with Mach 7 velocity. A future tactical railgun will hit targets at ranges almost 20 times farther than conventional surface ship combat systems.

高速的海军水面作战中心达尔格伦部位于12月10日，2010年美国海军研究办公室电磁轨道炮，发射了世界记录设置33兆焦耳出手，打破了以往的纪录成立2008年1月31日摄像机的图像。轨道炮是一种远距离，高能量炮发射系统比使用火药火箭发动机或电力而推出的引人注目的弹丸在超过200海里7马赫的速度范围与目标的能力。一个未来的战术轨道炮将打击目标范围近20倍远高于传统的水面舰艇作战系统。
