想象一个巨型的轨道炮出现在肯尼迪太空中心上的样子吧。

' Today 's railgun test demonstrates the tactical relevance of this technology , which could one day complement traditional surface ship combat systems , ' adm carr said .

“今天的电磁炮试射显示了该技术的战术价值，也许我们有一天会把它应用到传统水面舰艇作战系统的，”carr少将说道。

The railgun is a longe-range , high-energy device that uses electricity instead of explosives or propellants to launch projectiles , which could reduce the need to carry explosives or chemical propellants out to sea .

轨道炮是一种长距离、高能量设备，它使用电力而非爆炸物或者推进器来发射炮弹，这样就可以减少将爆破物或者化学推进剂运到海上的需要。
