Boeing yal-1

Exactly 20 years ago today, a modified Boeing F took its first flight. The only difference? The US military started the airborne laser program ABL inbut an experimental prototype was already tested more than a decade ago, boeing yal-1.

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. It comprises six sedan-sized interconnected systems, each weighing approximately 3,kg 6, lbs source.

It was primarily designed to test its feasibility as a missile defense system to destroy tactical ballistic missiles TBMs while in boost phase. Department of Defense. The YAL-1 with a low-power laser was test-fired in flight at an airborne target in It was ultimately scrapped in September after all usable parts were removed. It shot down several missiles in tests conducted in the s. The development of the system was being accomplished by a team of contractors. These tests fully qualified the system so that it could be integrated into the actual aircraft. Following the completion of the tests, the laboratory was dismantled, and the fuselage was removed. The aircraft was built as a F freighter at the Boeing Everett Factory with manufacturer's serial number and fuselage line number The aircraft took its first flight on 6 January The aircraft took to the skies again on 18 July On March 15, , the YAL-1 successfully fired this laser in flight, hitting its target. The target was an NCE Big Crow test aircraft that has been specially modified with a "signboard" target on its fuselage. The test validated the system's ability to track an airborne target and measure and compensate for atmospheric distortion.

The future of airborne laser technology holds significant potential for various applications and advancements in defense and other fields.

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.

COILs in the late 90s were eight times more powerful than earlier generations source. It comprises six sedan-sized interconnected systems, each weighing approximately 3,kg 6, lbs source. Each of these systems has 3, individual parts source. The source of this immense energy comes from chemical reactions. Hydrogen peroxide decays to produce oxygen, which in turn energizes iodine source.

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.

It was designed to shoot down ballistic missiles in the boost phase of their flight, providing a defensive capability against missile threats. The radar emits electromagnetic waves and analyzes the returning signals reflected off the target to determine its range, speed, and trajectory. Chemical Mixing: The gaseous oxygen and iodine were mixed in a reaction chamber within the laser system. You can help Wikipedia by expanding it. The main aim was to test the COIL or chemical oxygen iodine laser system and perform elaborate checks to ensure all components fit well. Optical Pump Source: The laser system requires an optical pump source to energize the chemicals and initiate the laser reaction. It successfully demonstrated the ability to track and destroy multiple test targets during its testing phase. The YAL-1 has contributed substantially to this projected trend. Tiahrt, who thinks that this program should, or would, ever be operationally deployed. Orlando Sentinel. Tracking used a conical scanning technique, which employed the beam of the boresighted high-energy laser to acquire and track the target vehicle via its illuminated infrared return.

The very idea of hitting a hostile ballistic missile with a laser beam produced by an airborne emitter sounds like science fiction. But such tests involving a Jumbo Jet equipped with a high-energy laser utilizing chemical reaction were indeed conducted some fifteen years ago.

Flight Image of the Day. Login Register. The Airborne Laser program was scrapped in due to high costs and inoperability. Here are a few key areas that could shape the future of airborne laser technology: Missile Defense: Airborne laser systems continue to be explored for missile defense applications. While the program was discontinued, it provided valuable insights and technological advancements that have influenced subsequent research and development efforts in directed energy weapons. Archived from the original on October 20, The ABL adaptive optics use the turbulence measurement to compensate for atmospheric errors. Toggle limited content width. The Laser System and How it Works. And there's nobody in uniform that I know who believes that this is a workable concept. July 29, Before working on the real thing, the Air Force performed laser tests on a retired Air India Boeing in Hidden categories: All articles with dead external links Articles with dead external links from October Articles with permanently dead external links Articles with dead external links from September Articles with short description Short description matches Wikidata Use mdy dates from January Short description is different from Wikidata All articles with unsourced statements Articles with unsourced statements from February Articles with unsourced statements from August Articles with unsourced statements from May Commons category link from Wikidata Webarchive template wayback links Coordinates on Wikidata.
