在这部国家地理：超级航母大揭秘纪录片片中,The American Military's most advanced weapon—the Nuclear Powered Aircraft Carrier—is about to take on the 21st Century with the most significant technological change in over 50 years. Watch an exclusive, behind the scenes journey of the development and testing of EMALS, the electro magnetic aircraft launch system that will be state of the art on the US Navy's new class of Aircraft Carriers. 危机时刻,航空母舰的首要任务就是让战斗机起飞，投入战斗。让喷气式战斗机在大约90米长的甲板上起飞,是一项重大的技术挑战。因为飞机的速度要在两秒内从零增加到270公里/时。美国海军一直使用蒸汽弹射器弹射战斗机。现在,工程师正研发一种新系统—电磁弹射器。
