The X-35C touched down at Patuxent River NAS on 10 February 2001, completing the first-ever transcontinental flight of a JSF demonstrator aircraft and initiating a series of flight tests that demonstrated carrier suitability in sea-level conditions. The X-35C's flight-test program included a series of Field Carrier Landing Practice tests to evaluate the aircraft's handling qualities and performance during carrier approaches and landings at an airfield, and also included up-and-away handling-quality tests and engine transients at varying speeds and altitudes

g2 X$ X5 Q6 ^2001年2月10日X-35 C抵达 Patuxent 河国家科学院，完成了JSF 型号机型的首次不间断横贯大陆的飞行试验，并且开始验证一系列在海上条件下同航母适配的的飞行测试。X-35 C系列试验科目包括一系列的Field Carrier Landing Practice以验证飞机在陆地机场起降的操作性能，也包括测试在起降操作性能上突然改变速度和高度产生的发动机的瞬时性能等。
