美軍研製的機載激光反導系統周四晚在太平洋上空進了兩次測試，並取得了圓滿成功。
美軍當天擊落的靶彈相當於前蘇聯生產的飛毛腿 導彈大小。美軍飛機發射的激光柱有籃球粗細，可攔截速度達每小時6400公里的各類導彈。
美國 國防部透露，在被高能激光束照射了數秒後，目標導彈即因過熱而解體。
分析人士推測，美軍機載反導系統的有效殺傷距離在160公里以上。當第一次導彈攔截成功後，載有激光發射器的波音747飛機馬不停蹄地飛往另一戰區，成功攔截了第二枚來襲導彈。最初的報道只說摧毀了一枚導彈。
在今次試驗中，美軍發射的靶彈都從靠近美國本土的海上平台起飛。此後數秒，美軍機載反導系統就捕獲到了目標的軌迹，並且使用一個低能激光束來對其進行跟踪。在確定了目標的速度和大氣折射度後，主激光武器開始照射靶彈，最終利用超高溫將其徹底摧毀。

【明報專訊】電影《星球大戰》的激光炮不再是天方夜譚。美國 導彈防禦局周五宣布，首次成功利用空中激光武器擊落一枚彈導導彈。這次攔截試驗成功，標誌美國導彈防禦系統進入一次新紀元，準確度極高的高能量激光武器，未來可能成為美軍王牌武器。
美軍今次測試的是「空載激光武器測試平台」（ALTB），結合了美國最頂尖的航天和軍事科技。發射器安裝在由波音747噴射機改裝的飛機內、軍火商Northrop Grumman公司供應高能量激光，洛歇馬丁（Lockheed Martin）研發光束和發射系統。
波音747發射2分鐘中目標
試驗在周四進行，當局先在加州中部對出海面發射一枚短程彈導導彈，波音747飛機在加州愛德華茲空軍基地出發攔截。飛機先利用機上的感應器探測導彈位置，並以低能量激光追蹤，其後發射高能激光判斷大氣干擾狀况，最後發射激光將目標摧毁。
導彈防禦局稱﹕「這是首次直接利用空中致命能量攔截系統擊落液化推進彈導導彈目標」。該局稱，高能激光在導彈發射2分鐘內便能擊中目標。當局預期新技術可降低軍方攔截任務的成本，而且激光武器攻擊目標時較彈頭更迅速和精準，可減少不必要的傷亡。它還預測，空中激光武器有潛力同時對準多個目標，以光速擊中上千公里外的目標。

美以激光摧毀導彈試驗成功
(明報)2010年2月13日 星期六 17:20
美國 空軍表示，在加州海岸進行高能量的激光試驗，成功摧毀一枚飛行中的導彈。
美國空軍和波音公司周五宣布，試驗在周四晚進行。聲明稱，飛機運載的高能量激光系統追蹤到一枚在加州海岸上空加速飛行的目標導彈，然後透過能量光束，把導彈摧毀。這是首次以激光系統摧毀導彈。美國空軍表示，被毀的導彈是液態燃料推動的導彈。
高能量激光系統載具是一架波音747，該機先後發射三次激光，分別用以追蹤、修正和摧毀導彈。
美國官員表示，新技術成本較低，能夠在短時間內重覆發射，在同一時間打擊多枚敵方導彈。(綜合)

美國成功以導彈測試機載激光
U.S. successfully tests airborne laser on missile
WASHINGTON, Feb 12 (Reuters) -
A U.S. high-powered airborne laser weapon shot down a ballistic missile in the first successful test of a futuristic directed energy weapon, the U.S. Missile Defense Agency said on Friday.
華盛頓 2月12日（路透社） - 一件美國高馬力的機載激光武器，在未來的定向能量武器的首次測試中，成功擊落一枝彈道導彈，美國導彈防禦局週五表示。
The agency said in a statement the test took place at 8:44 p.m. PST (11:44 p.m. EST) on Thursday /0444 GMT on Friday) at Point Mugu's Naval Air Warfare Center-Weapons Division Sea Range off Ventura in central California.
"The Missile Defense Agency demonstrated the potential use of directed energy to defend against ballistic missiles when the Airborne Laser Testbed (ALTB) successfully destroyed a boosting ballistic missile" the agency said.
“導彈防禦局以抵禦彈道導彈示範定向能量的潛在用途，當機載激光試驗台（ALTB）成功地摧毀了一枝推動的彈道導彈”該機構說。
The high-powered Airborne Laser system is being developed by Boeing Co., (BA.N) the prime contractor, and the U.S. Missile Defense Agency.
那高馬力的機載激光系統正由主要合約商波音公司（BA.N），和美國導彈防禦局發展。
Boeing produces the airframe, a modified 747 jumbo jet, while Northrop Grumman (NOC.N) supplies the higher-energy laser and Lockheed Martin (LMT.N) is developing the beam and fire control systems.
"This was the first directed energy lethal intercept demonstration against a liquid-fuel boosting ballistic missile target from an airborne platform," the agency added.
“這是第一次定向能量在一空運的平台，針對一液體燃料推進的彈道導彈目標，作致命攔截示範”該機構說。
The airborne laser weapon successfully underwent its first in-flight test against a target missile back in August. During that test, Boeing said the modified 747-400F aircraft took off from Edwards Air Force Base and used its infrared sensors to find a target missile launched from San Nicolas Island, California.
The plane's battle management system issued engagement and target location instructions to the laser's fire control system, which tracked the target and fired a test laser at the missile. Instruments on the missile verified the system had hit its mark, Boeing said.
The airborne laser weapon is aimed at deterring enemy missile attacks and providing the U.S. military with the ability to engage all classes of ballistic missiles at the speed of light while they are in the boost phase of flight.
"The revolutionary use of directed energy is very attractive for missile defense, with the potential to attack multiple targets at the speed of light, at a range of hundreds of kilometers (miles), and at a low cost per intercept attempt compared to current technologies," the U.S. Missile Defense Agency said.
