【RQ-4全球鷹】美國最貴最無人機，造價高達2億美金，能留空60個小時,一次飛行可偵察700萬平方裏

RQ-4全球鷹（英語：Global Hawk）是由諾斯洛普·格魯門所生產製造的無人飛機（UAV），主要服役於美國空軍與美國海軍。 該機角色上類似1950年代叱吒風雲屢次被擊落的洛克希德U-2偵察機。它可以提供後方指揮官綜觀戰場或是細部目標監視的能力。它裝備有高分辨率合成孔徑雷達，可以看穿雲層和風沙，還有光電紅外線模組（EO/IR）提供長程長時間全區域動態監視。白天監視區域超過100,000平方公里（40,000平方英哩）。例如，要監視洛杉磯一樣大的城市，可以從緬因州遙控環球之鷹，拍攝370 x 370公里（230 x 230英哩）區域的洛杉磯市區24小時，然後悠閒地飛回家。 它還有潛在能力可以進行波譜分析的諜報工作，提前發現全球各地的危機和衝突。也能幫忙導引空軍的導彈轟炸。使誤擊狀況降低。 “R”開頭的名稱是美國國防部命名偵察（reconnaissance）的第一個英文字母；“Q”指無人飛機；“4”是指無人飛機計劃第4架作品。 “A”或“B”則是兩種不同的衍生版本。 全球鷹是第一架得到美國聯邦航空局（FAA）認證可以在美國民航機領空飛行的無人機。 這算是無人機產業一大革命，日後可能出現不需駕駛員操縱的商用飛機。 The RQ-4 Global Hawk (English: Global Hawk) is an unmanned aircraft (UAV) manufactured by Northrop Grumman and is mainly used in the U.S. Air Force and the U.S. Navy. The role of the aircraft is similar to the Lockheed U-2 reconnaissance aircraft that was repeatedly shot down in the 1950s. It can provide the rear commander with the ability to observe the battlefield or monitor detailed targets. It is equipped with a high-resolution synthetic aperture radar, which can see through clouds and wind and sand, and an electro-optical infrared module (EO/IR) to provide long-range and long-term dynamic monitoring of the whole area. During the day, the surveillance area exceeds 100,000 square kilometers (40,000 square miles). For example, if you want to monitor a city as big as Los Angeles, you can remotely control the Global Eagle from Maine, shoot the downtown area of ​​Los Angeles in an area of ​​370 x 370 kilometers (230 x 230 miles) for 24 hours, and then fly home leisurely. It also has the potential to perform espionage work with spectrum analysis, and spot crises and conflicts around the world in advance. It can also help guide the air force's missile bombing. Reduce the missed situation. The name beginning with "R" is the first English letter of the U.S. Department of Defense naming reconnaissance (reconnaissance); "Q" refers to the unmanned aircraft; and "4" refers to the fourth work of the unmanned aircraft program. "A" or "B" are two different derivative versions. The Global Hawk is the first UAV to be certified by the Federal Aviation Administration (FAA) to fly in the airspace of a US civil aircraft. This can be regarded as a major revolution in the UAV industry, and commercial aircraft that do not require pilots to operate may appear in the future.
