据报道,美国首架代号为“X-45A”的样机已完成测试,并于今年春天进行了试飞,首次试飞使用的是两架小型样机,今后还将对目前正在设计的增强型X-45B进行试飞,若试飞成功,则将为战术无人机进入实战提供了技术保证。另外,为了尽快将无人机装备部队,美方还加大了在2003财年中无人机的国防预算,希望能在2003年装备14架,从而使无人机实现战术化。预计到2010年,美空军大约有1/3的作战飞机将替换成无人作战飞机。
It is reported that the first prototype of the United States, code-named “X-45A”, has been tested and was tested in the spring of this year. Two small prototypes were used for the first flight test. In the future, the enhanced X-45B Test flight, if the test is successful, it will provide technical assurance for tactical UAV into real combat. In addition, in order to equip the drone as soon as possible, the United States has also increased its defense budget for the UAV in fiscal 2003, hoping to equip 14 aircraft in 2003 so that the UAV could be tacticalized. It is estimated that by 2010, about one-third of the U.S. air combat aircraft will be replaced by unmanned combat aircraft.
