Exactly 20 years ago today, a modified Boeing F took its first flight. The only difference?

An airborne laser ABL is a laser system operated from a flying platform, as in the:. Of note is that the ALL demonstrated one of the early uses of deformable mirror technology. To compensate for various atmospheric aberrations arising from turbulence and absorption of energy from the beam itself, it was necessary to modify the wavefront of the beam after it emerged from the laser resonator in order to ensure it would arrive at the target as a tightly focused spot. The ABL was mounted on a modified Boeing See Boeing YAL-1 for further discussion. The original ALL, being a relatively long wavelength, sub-megawatt laser, killed its targets via two mechanisms.

It was designed to shoot down ballistic missiles in the boost phase of their flight, providing a defensive capability against missile threats. The laser system used a chemical oxygen iodine laser COIL to emit a high-energy light beam. This laser was powerful enough to track and destroy ballistic missiles from a distance while still in their boost phase. The primary objective of the YAL-1 Airborne Laser program was to demonstrate the feasibility and effectiveness of using directed energy weapons to intercept and destroy enemy missiles. The boost phase interception was considered advantageous because it allowed for the destruction of missiles early in their trajectory, reducing the potential damage they could cause. The YAL-1 underwent a series of flight tests and ground-based tests to evaluate its capabilities. It successfully demonstrated the ability to track and destroy multiple test targets during its testing phase. However, the program faced various technical and operational challenges, including the limited range and duration of the laser system, the size and weight of the equipment, and the complexity of maintaining and operating the aircraft. Despite some successes, the YAL-1 Airborne Laser program was ultimately canceled in due to cost overruns, technical difficulties, and shifting priorities within the Department of Defense. The system was never deployed operationally, and the aircraft was retired. The YAL-1 Airborne Laser represented an ambitious effort to develop a laser-based missile defense system. While the program was discontinued, it provided valuable insights and technological advancements that have influenced subsequent research and development efforts in directed energy weapons.

Future airborne laser systems may incorporate solid-state lasers or other advanced laser technologies, enabling longer ranges, higher power outputs, and boeing yal-1 operational capabilities.

Lasers are a hallmark of military science fiction and, to casual observers, seem a long way off. This is not the case ; various nations have developed lasers for military purposes, namely, point defense. The Boeing YAL-1 represents a unique take on this trend and therefore is the subject of this article. Defense contractors designed the YAL-1 to intercept and destroy tactical theatre ballistic missiles during their launch stage source. Defense experts in the s identified lasers as a promising technology to tackle airborne threats, including planes and missiles source. COILs in the late 90s were eight times more powerful than earlier generations source.

Boeing is responsible for programme management, systems integration, battle management system and modification of the F aircraft. TRW is building the laser systems. Lockheed Martin Space Systems is responsible for the target acquisition and beam control systems. In April the ABL final critical design review was completed. In July , the modified aircraft took the first of a series of test flights.

This weekend, Saturday, November 6 and Sunday November 7, , the Thunder and Lightning over Tucson Airshow at Davis-Monthan AFB in Arizona will thrill aviation enthusiasts from around the world with a unique mix of aerial and static displays that can only be presented at one of the most unique military aviation installations on earth. But 9 years ago, in , at this same Davis-Monthan Airshow, there was a very special exhibit that only appeared once, and then disappeared forever. In addition to being a massive repository for spare aircraft and parts, the Boneyard is also a living museum, where some of the most fascinating stories in all of aviation sit in quiet repose as their history echoes on into the future long after their demolition. The Davis-Monthan Airshow is always a special show because of its proximity to unique aviation artifacts and resources like the Boneyard and the Pima Air and Space Museum. It was the only time the public ever got a close look at the most expensive aircraft in history. The program was plagued with complex testing, mixed results and stratospheric cost overruns. The YAL-1 did, however, eventually experience testing success when, in January , its laser weapon engaged a ballistic missile surrogate simulating a ballistic missile. The program, the most expensive military aircraft in history to date, was beginning to show promise.

Load more. These challenges, cost overruns, and shifting priorities led to the program's termination. The YAL-1 has contributed substantially to this projected trend. These emitted photons were directed and amplified by the mirrors in the laser resonator, creating a high-energy laser beam. Sophisticated tracking and targeting systems were employed to ensure accurate alignment with the ballistic missile. Optical Pump Source: The laser system requires an optical pump source to energize the chemicals and initiate the laser reaction. In addition to the costs, the YAL-1 also had other operational drawbacks and range issues. DEWs utilize focused energy, such as lasers or high-powered microwaves, to damage or disable targets. Parallel Designs 2. It heated the missile skin, weakening it, causing failure from high-speed flight stress.

The target was an NCE Big Crow test aircraft that has been specially modified with a "signboard" target on its fuselage. Union of Concerned Scientists. Center for Strategic and International Studies. Fire Control System: The fire control system integrated the inputs from the ATP subsystem and adaptive optics system to calculate the necessary adjustments for the beam director. COIL 2. This type of laser utilized a chemical reaction to produce a high-energy beam of light capable of destroying ballistic missiles. In an April 6, press conference, the Secretary of Defense Robert Gates recommended the cancellation of the planned second ABL aircraft and said that the program should return to a Research and Development effort. The test validated the system's ability to track an airborne target and measure and compensate for atmospheric distortion. The Airborne Laser program was scrapped in due to high costs and inoperability. These tests fully qualified the system so that it could be integrated into the actual aircraft. The YAL-1 Airborne Laser represented an ambitious effort to develop a laser-based missile defense system. Tools Tools.
