坎大哈的野獸-美三角型隱型無人駕駛戰機





美軍證實使用隱身無人機 可搜集中巴導彈數據

中評社香港12月9日電/據美國《航空周刊與空間技術》網站報道,

美國空軍已經向《航空周刊》證實存在所謂的“坎大哈野獸”隱身遙控噴氣無人機,該機曾在2007年底在阿富汗上空出現。

  該RQ-170“哨兵”(Sentinel)據信是採用無尾飛翼布局,傳感器平滑地安裝在機翼的上表面,該機由洛克希德.馬丁公司先進研究計劃項目部(Advanced Development Programs,ADP,也就是著名的臭鼬工程隊)支持開發。一名空軍軍官在12月4日透露空軍“正在開發一種為前線部署的作戰部隊提供偵察和監視支援的隱身無人機系統(UAS)”。

  《航空周刊》的技術博客和其他網站均曾討論過該無人機,但是美國空軍提供給《航空周刊》的官方聲明是該無人機的首次細節披露。

  電子郵件形式的官方聲明中稱:“RQ-170的裝備是與國防部長羅伯特.M.蓋茨增加對作戰指揮官的情報、監視和偵察(ISR)支援的要求和空軍參謀長諾頓.施瓦茲關於提高美國空軍對於無人機依賴程度的觀點密切相連。”

  RQ-170目前由Tonopah測試試驗場的第30偵察中隊負責測試使用,當F-117隱身戰鬥機還處於保密階段時也部署在該試驗場,該無人機隸屬於空中作戰司令部位於克裡奇空軍基地的第432聯隊,“哨兵”曾被看到從通用原子航空系統公司的飛機庫中出現。

  2005年9月1日,第57作戰集群下設第30偵察中隊,2007年7月17日正式批准了該編制。儘管不能代表整個事件,但是中隊編制的正式設立仍引起了跟蹤國防秘密事件各種跡象的人士的關注。

  RQ-170的編號與F-117相似,正確的前綴,但是其特別序列號是為了防止對於該項目存在情況顯而易見的猜測。從技術角度分析,RQ編號指出這是一架非武裝無人機,而MQ前綴則是指“捕食者”和“死神”之類的武裝無人機。美國空軍的官方聲明中有“支援前線部署的作戰部隊”的字樣,當考慮到其他的細節時,表明該無人機具備中等程度的隱身能力(包括鈍前緣,簡單噴管和翼上傳感器吊艙),同時“哨兵”是基於戰術作戰使用的平台,而不是戰略級的情報搜集設計。

  關於該無人機的使用仍存在許多疑問。如果它是一個高空無人機,那麼它的塗裝是一種非常獨特的顔色—中度灰色,這與“捕食者”或“死神”相似,但是與最高空飛行器實用的深灰或全黑差異很大。“哨兵”翼展約為65英尺,尺寸與MQ-9“死神”近似。根據互聯網上有限的圖片判斷(所有圖片均為左側拍攝),無人機是一個中心寬厚融合至外翼的構型。
根據其低觀測性設計,無人機可用於伊朗邊境地區飛行以及監視中國、印度和巴基斯坦的導彈試射,搜集相關數據,也可執行諸如信號和多光譜情報搜集等任務。

'坎大哈的野獸'後的神秘被暴露

Can fly unnoticed through radar
Faster, more manoeuvrable than the Predator
May be used for Iran, Pakistan surveillance


Over the last two weeks, an increasingly steady stream of grainy images have appeared on the internet of a strange, sleek new aircraft spotted in the skies above the war-torn country.
Now the US Army has confirmed it - the RQ Sentinel stealth drone is real.
Shaped like a B-2 stealth bomber and created by Lockheed Martin, the Sentinel has no metal parts outside its engine and can fly completely unnoticed through areas "thick with radar".
The aircraft is also coated with a special paint, or "secret sauce", as it was described to FOX News by Oklahoma State University's associate professor of Aerospace engineering Dr Jamie D. Jacob.

"It is jet-powered - probably twin turbojet or low bypass ratio turbofan engines - so it'll be faster and more manoeuvrable than a comparable Predator vehicle and have the ability to fly higher," he said.

"We don't know what the range is, but it should easily be able to cover most of Iran and Pakistan based out of Kandahar."

The Sentinel is reportedly set up as a "troop support sensor platform", meaning it's unlikely to carry Hellfire missiles such as that fired by the current fleet of Predator aircraft.
Whether that will change once the Sentinel is rolled out is up for debate, as bad publicity mounts about the increasing use of "death robots" in conflict zones.

The Sentinel will at the very least be far more capable at seeking out and pinpointing enemy targets, and may even be used in the search for Osama bin Laden, Dr Jacob said, while questioning the need for stealth surveillance craft in Afghanistan.

"The Taliban and Al Qaeda don't have radar-seeking missiles we know of, so Predators and Global Hawks should work fine," he told FOX New.
"This may mean then that Afghanistan is being used as a base of operations to fly covert surveillance missions over Iran, who do have radar based ground-to-air missiles."
