美国无人机被击落

In what appeared to have been a major provocation, Iran shot down what the U.S. military said was an unarmed and unmanned U.S. RQ-4A Global Hawk drone flying in international airspace over the Gulf of Oman near the Strait of Hormuz.

伊朗击落了一架美国RQ-4A“全球鹰”无人机,美国军方说,这架无人机没有武装,无人驾驶,在霍尔木兹海峡附近的阿曼湾上空的国际空域飞行。

"This was an unprovoked attack on a U.S. surveillance asset in international airspace," Navy Capt. Bill Urban, a U.S. Central Command spokesperson said in a statement.

美国中央司令部发言人、海军上尉比尔·厄本在一份声明中说,“这是对美国在国际空域的一项监视资产的无端攻击。”

The RQ-4A Global Hawk is a $120 million surveillance drone which CENTCOM said "provides real-time intelligence, surveillance and reconnaissance missions (ISR) over vast ocean and coastal regions.”

RQ-4A“全球鹰”是一架价值1.2亿美元的无人侦察机,美国中央司令部说,它“在广阔的海洋和沿海地区提供实时情报、监视和侦察任务”。

The aircraft has a wingspan on 116.2 ft, nearly the same size of the Boeing 737 Max, and is able to reach altitudes of 65,000 feet.

飞机翼展116.2英尺,几乎与波音737 Max相同大小,能够达到65,000英尺的高度。

According to the drone's developer, Northrop Grumman, the drone "flies autonomously at altitudes of more than 60,000 feet, above inclement weather and prevailing winds, for more than 32 hours at a time" and has amassed more than 20,000 flight hours.

据无人机的开发商诺斯罗普·格鲁曼公司称,该无人机“可以在超过6万英尺的高度,在恶劣天气和盛行风之上自主飞行,每次飞行时间超过32小时”,累计飞行时间超过2万小时。

The first generation experimental Global Hawks were deployed to the Persian Gulf less than two months after Sept. 11, 2001.

2001年9月11日之后不到两个月,第一代实验性全球鹰就被部署到了波斯湾。

In 2006, the RQ-4A became the first unmanned aircraft system to earn both a military airworthiness certification and a national certificate of authorization to operate in the national airspace, according to Northrop Grumman.

根据诺斯罗普·格鲁曼公司的说法,在2006年,RQ-4A成为第一个获得军用适航认证和国家授权在国家领空运行的无人机系列。

"With this historic accomplishment and more than 35,000 total flight hours, most of that time in combat support over the skies of Iraq and Afghanistan, Global Hawk continues to be a trailblazer in UAS certifications and a pathfinder supporting our men and women overseas in combat," George Guerra, vice president of HALE systems for Northrop Grumman, said in a statement.

”带着这一历史性的成就和超过35000飞行小时,全球鹰大部分时间都在支持在伊拉克和阿富汗的天空中的战斗,“它在无人机认证和支持我们的空军在海外作战时仍然是一个开拓者,”乔治·圭拉,诺斯罗普·格鲁曼公司的副总裁,在一份声明中说。
