The ABL weapon system consists of a high-energy, chemical oxygen iodine laser (COIL) mounted on a modified 747-400F (freighter) aircraft to shoot down theater ballistic missiles in their boost phase.

A crew of four, including pilot and copilot, would be required to operate the airborne laser, which would patrol in pairs at high altitude, about 40,000 feet, flying in orbits over friendly territory, scanning the horizon for the plumes of rising missiles.

Capable of autonomous operation, the ABL would acquire and track missiles in the boost phase of flight, illuminating the missile with a tracking laser beam while computers measure the distance and calculate its course and direction. After acquiring and locking onto the target, a second laser - with weapons-class strength - would fire a three- to five-second burst from a turret located in the 747's nose, destroying the missiles over the launch area.

The airborne laser would fire a Chemical Oxygen Iodine Laser, or COIL, invented at Phillips Lab in 1977. The laser's fuel consists of the same chemicals found in hair bleach and Drano - hydrogen peroxide and potassium hydroxide - which are then combined with chlorine gas and water.


The laser operates at an infrared wavelength of 1.315 microns, which is invisible to the eye. By recycling chemicals, building with plastics and using a unique cooling process, the COIL team was able to make the laser lighter and more efficient while - at the same time - increasing its power by 400 percent in five years. The flight-weighted ABL module would be similar in performance and power levels to the multi-hundred kilowatt class COIL Baseline Demonstration Laser (BDL-2) module demonstrated by TRW in August 1996.


As its name implies, though, it would be lighter and more compact than the earlier version due to the integration of advanced aerospace materials into the design of critical hardware components. For the operational ABL system, several modules would be linked together in series to achieve ABL's required megawatt-class power level. Atmospheric turbulence, which weakens and scatters the laser's beam, is produced by fluctuations in air temperature [the same phenomenon that causes stars to twinkle].


Adaptive optics rely on a deformable mirror, sometimes called a rubber mirror, to compensate for tilt and phase distortions in the atmosphere. The mirror has 341 actuators that change at a rate of about a 1,000 per second. The Airborne Laser is a Major Defense Acquisition Program. After the Concept Design Phase is complete, the ABL will enter the Program Definition and Risk Reduction (PDRR) Phase.


The objective of the PDRR phase is to develop a cost effective, flexible airborne high energy laser system which provides a credible deterrent and lethal defensive capabilities against boosting theater ballistic missiles. The ABL PDRR Program is intended to show high confidence system performance scalable to Engineering and Manufacturing Development (EMD) levels.


The PDRR Program includes the design, development, integration, and testing of an airborne high-energy laser weapon system. In May 1994, two contracts were awarded to develop fully operational ABL weapon system concepts and then derive ABL PDRR Program concepts that are fully traceable and scaleable EMD.


A single contract team was selected to proceed with the development of the chosen PDRR concept beginning in November 1996. Successful development and testing of the laser module is one of the critical 'exit criteria' that Team ABL must satisfy to pass the program's first 'authority-to-proceed' (ATP-1) milestone, scheduled for June 1998. Testing of the laser module is expected to be completed by April 1998. The PDRR detailed design, integration, and test will culminate in a lethality demonstration in the year 2002.


A follow-on Engineering Manufacturing and Development/Production (EMD) effort could then begin in the early 2003 time frame. A fleet of fully operational EMD systems is intended to satisfy Air Combat Command's boost-phase Theater Air Defense requirements. If all goes as planned, a fleet of seven ABLs should be flying operational missions by 2008.


Performance requirements for the Airborne Laser Weapons System are established by the operational scenarios and support requirements defined by the user, Air Combat Command, and by measured target vulnerability characteristics provided by the Air Force lethality and vulnerability community centered at the Phillips Laboratory. The ABL PDRR Program is supported by a robust technology insertion and risk reduction program to provide early confidence that scaling to EMD performance is feasible.


The technology and concept design efforts provide key answers to the PDRR design effort in the areas of lethality, atmospheric characterization, beam control, aircraft systems integration, and environmental concerns. These efforts are the source of necessary data applied to exit criteria ensuring higher and higher levels of confidence are progressively reached at key milestones of the PDRR development. The key issues in the program will be effective range of the laser and systems integration of a Boeing 747 aircraft.

空載雷射 (Airborne Laser) 武器系統

ABL 是使用波音747-400F﹙貨機型﹚裝載百萬瓦級的化學雷射武器系統，主要目標是利用高能雷射，將正在發射昇空的敵方來襲彈導飛彈予以擊落摧毀。由於此武器統從發射到擊中遠方飛彈所需時間極短（一般防禦飛彈最多只能超音速，但雷射系統為光速），所以ABL 系統的成功部署對於美國飛彈防禦能力的提昇將是一項重要的棋子。



Airborne Laser Conformal Window Exposed During Flight

空中雷射系統的發射窗在飛行中展露


Air Force Lt. General Henry “Trey” Obering, Missile Defense Agency Director, announced today that the Airborne Laser’s 1.7-meter-wide conformal window was successfully exposed during flight for the first time, a maneuver necessary for the weapon system to complete its future mission of shooting down a ballistic missile during the boost phase.
美國飛彈防禦局局長空軍中將Henry  Obering(綽號"三點")今天宣布空中雷射系統的一點七公尺寬的發射窗第一次在飛行途中成功的展露出來,這是空中雷射系統在正式可射擊彈道飛彈程序前的一項必須的運作


The conformal window exposure occurred on May 17 during the eighteenth flight in the current test series for the Airborne Laser aircraft.
這個發射窗是空中雷射系統在五月十七日所實施的現階段測試的第十八次飛行時展露出來


The window, which is shaped like a huge contact lens, took five years to manufacture and is one of the most complex optics ever developed.
這個發射窗的形狀像一個大型的隱形眼鏡鏡片,共花了五年的時間來製造,是發展過最複雜的光學儀器.


It is mounted in a rotating turret-ball assembly on the nose of the Airborne Laser aircraft.
它被裝置在空中雷射機機鼻的一個旋轉鏡頭轉台總成中


During takeoff and landing, the window is rotated into the “stowed” position where it is protected by a gasket and shield. 在起飛及著陸階段,這個發射窗是旋轉收入一個用襯墊及防護罩保護的"收藏"位置


During an operational mission, three of the four lasers that propagate outside the aircraft, including the megawatt-class “killer” laser, are fired through the conformal window.
在執行作戰任務時,包括高瓦特的殺手雷射在內的四個雷射中的三個會由這個發射窗射出飛機


Although the lasers have not yet been installed aboard the aircraft, the exposure test, referred to as “unstowing the turret ball,” is an important part of the flight test series being conducted this year.
雖然結至目前為止這些雷射系統並沒有安裝在飛機上,但這個被視為將旋轉鏡頭轉入運作位置的展露測試是本今年的飛行測試中的重要階段


The Airborne Laser is one of the boost-phase segments of the overall integrated missile defense system, being developed to defend the United States, its allies and its deployed troops from ballistic missile attack.
空中雷射系統是為了防範美國及盟國與部隊,免受彈道飛彈攻擊的一個整合飛彈防禦系統發展階段的一部分
