Glossary term
ABL (airborne laser)
TERM SUMMARY
ABL stands for airborne laser, a laser system carried by an aircraft. NATO glossaries use the term, and NATO has applied it to the U.S. Boeing 747-mounted boost-phase intercept laser.

ABL is the abbreviation for airborne laser. It refers to a laser system carried by an aircraft. NATO's glossary of acronyms and abbreviations lists "ABL" with the expansion "airborne laser", and a NATO Science and Technology Organisation publication gives the same definition: "ABL = Airborne Laser."
In NATO material the term appears in discussions of high-energy lasers, atmospheric effects on laser beams and missile defence. NATO has also used ABL as the name of a specific system, the U.S. Boeing 747-mounted boost-phase intercept laser. Sources for these points are the NATO acronym glossary (AAP-15) and the NATO STO educational note EN-SCI-340.
The Boeing 747 system and its YAL-1A designation
NATO describes the U.S. system as a Boeing 747-mounted boost-phase intercept laser and identifies it as the "Airborne Laser", abbreviated ABL. Boost phase is the powered stage of a ballistic missile's flight, and that is the stage this system was built to engage. The NATO description is available in a NATO opinion piece on the system.
A U.S. Army medical publication on laser hazards adds that the Airborne Laser was designated YAL-1A and was designed to destroy theatre ballistic missiles during the powered boost phase. The designation is useful when you are reading U.S. technical or program documents, which may use YAL-1A where NATO texts use ABL. The publication is the U.S. Army laser chapter.
The laser technology behind ABL
The U.S. Defense Advanced Research Projects Agency states that the Chemical Oxygen-Iodine Laser formed the basis of the Air Force's Airborne Laser. That places ABL in the family of high-energy chemical lasers rather than in the lower-power lasers used for ranging or target designation. DARPA's account is on its page for the MIRACL innovation timeline.
Related laser abbreviations in NATO technical material
The NATO technical publication that defines ABL lists several neighbouring terms. Bid teams reading defence directed-energy documents will meet them together:
- ABL: Airborne Laser
- SBL: Space Based Laser
- THEL: Tactical High Energy Laser
- ATL: Advanced Tactical Laser
The list shows that ABL is one platform category among several. Each abbreviation names a different way of carrying or using a high-energy laser: on an aircraft, in space, or in a tactical role.
What ABL means for a supplier bidding on Canadian public contracts
ABL is a technology term from NATO and allied defence literature. It does not designate a Canadian buyer, solicitation type or contract clause. If you see it in a Canadian tender, in a standard or in a technical annex, read it as "airborne laser" and check the statement of requirement for the actual scope.
Suppliers working in laser, optics, beam control or aerospace integration can use the NATO glossary and the related abbreviations above to read allied technical documents accurately. When a requirement cites a NATO publication, use the definition in that publication in your technical response, and keep your terminology consistent with it.
