1·Nor do UAS have to be rotated in and out of a war zone like manned aircraft.

因为在提供支援时，“无人飞行系统”通常是远离冲突区域的，它们绝不会像有人飞行器那样在战场上飞进飞出。

2·Along with persistence, UAS have other potential advantages over manned aircraft.

相比于有人飞行器，“无人飞行系统”还拥有除了毅力以外的其他优势。

3·The UAV costs less than the manned aircraft but its ability is growing at a very quick speed.

无人机的价格只有载人飞机的几分之一，而它们的能力正以指数形式增长。

4·Moreover, drone engines are smaller-and therefore cooler-than those powering heavier, manned aircraft.

此外，无人机的发动机比要驱动沉重的有人驾驶飞机的发动机体积小，因而发热更低。

5·NASA charges the same price — US$3, 500per hour — to use the Global Hawk as for various manned aircraft.

根据美国国家航空航天局规定，与有人驾驶飞机使用规则一样，“全球鹰”飞行时每小时收费3500美元。

6·UAV will be the supplemental and strengthening way for the satellite and manned aircraft in the reconnaissance missions.

无人机将成为侦察卫星、有人驾驶侦察机的重要补充与增强手段，成为未来战场上广泛应用的一种侦察工具。

7·Another potential advantage for UAS is that future designs may be better able to survive in contested airspace than manned aircraft are.

无人飞行系统的另一潜在优势是，其以后的设计会使其比载人飞行器更好地存活于竞争激烈的空域。

8·Target practice needs the cooperation from the Air Force so time and place are limited. Moreover, the manned aircraft is dangerous and is expensive.

炮兵打靶需要让空军配合练习，这样时间地点都受到制约，并且真飞机风险大训练成本昂贵。

9·In 30 years it should be technically feasible to imbue drones with all the capabilities of manned aircraft as well as some extra powers of their own.

在未来30年内，从技术上来说，在无人机上全额加载有人机的独有能力以及附加上无人机独有能力是行的通的。

10·But it is also capable of another trick: the ability to defend itself, like a jet fighter, if it is attacked by another drone or by a manned aircraft.

它也具有另一种技艺：倘若遭到另一架无人机或有人驾驶战机袭击，它能像喷气式战斗飞机那样，实行自卫。
