Subject: Airborne Laser Test Bed Successful in Lethal Intercept Experiment
doggtag    2/12/2010 7:50:27 PM
latest on the ABL program, from the US Missile Defense Agency, link courtesy of Defense-Aerospace.Com: ( http://www.defense-aerospace.com/article-view/release/112256/airborne-laser-shoots-down-missile-during-boost-phase.html ) Airborne Laser Test Bed Successful in Lethal Intercept Experiment (Source: Missile Defense Agency; issued Feb. 11, 2010) The Missile Defense Agency demonstrated the potential use of directed energy to defend against ballistic missiles when the Airborne Laser Test Bed (ALTB) successfully destroyed a boosting ballistic missile. The experiment, conducted at Point Mugu Naval Air Warfare Center-Weapons Division Sea Range off the central California coast, serves as a proof-of-concept demonstration for directed energy technology. The ALTB is a pathfinder for the nation's directed energy program and its potential application for missile defense technology. At 8:44 p.m. (PST), February 11, 2010, a short-range threat-representative ballistic missile was launched from an at-sea mobile launch platform. Within seconds, the ALTB used onboard sensors to detect the boosting missile and used a low-energy laser to track the target. The ALTB then fired a second low-energy laser to measure and compensate for atmospheric disturbance. Finally, the ALTB fired its megawatt-class High Energy Laser, heating the boosting ballistic missile to critical structural failure. The entire engagement occurred within two minutes of the target missile launch, while its rocket motors were still thrusting. This was the first directed energy lethal intercept demonstration against a liquid-fuel boosting ballistic missile target from an airborne platform. 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, and at a low cost per intercept attempt compared to current technologies. Less than one hour later, a second solid fuel short-range missile was launched from a ground location on San Nicolas Island, Calif. and the ALTB successfully engaged the boosting target with its High Energy Laser, met all its test criteria, and terminated lasing prior to destroying the second target. The ALTB destroyed a solid fuel missile, identical to the second target, in flight on February 3, 2010. -ends-

The question I have is, might this also be effective on faster burn, non-ballistic profile SAM's - say S-300/400 class? I've not seen it mentioned in their specifications, but such an ability would be attractive.
 
Nonetheless, an actual ballistic missile shootdown by a mega-watt laser - even under controlled conditions -  seems to me to be a "big" deal.
 
The announcement mentions a potential range of "hundreds of kilometers", but it would be fascinating to learn what the actual range for this test was. At least they've now destroyed both liquid and solid fueld rockets.

The last I remember reading, the Obamination had decided to terminate much of our anti-ballistic missile research, including the ALTB.  Does anyone know the current status of this program and/or others like it?

Red fumic nitric acid.
 
A COIL laser is proof of concept, but a diode pumped laser is much SAFER for the user.
 
ABL is an exercise in experimentation. Effective range is atmospheric thermal insulator and optical horizon limited. A MASER would solve one and altitude solves the other.

Red fumic nitric acid.

Where is this currently being used in the ABL?

What happens when ammonia hits chlorine, WP?
 
 
THAT is why this crap article is so misleading. COILs are incredibly dangerous.

Whoops, that should be WN instead of WP.

Is that the left-overs from the Chemical Oxygen Iodine Laser reaction?
Obviously, the firing sequence's "spent" fuel has to be tanked somewhere inside the aircraft after the firing sequence,
hence it thus rules out refueling of the laser chemicals while in flight.
 
Still, IIRC, it was suggested the platform would carry enough tankage of laser "fuel" for 40 engagements (can't suggest how long the average engagement firing sequence is, though).
So at some point, in addition to the ignition fuel, there must also be tankage /storage for the "spent" fuel...
 
Read a story supposing deployment of a pair of YAL-1's, with their call signs being Scalpel 1 and Scalpel 2, because of the precision targetting they offer.
Myself, I still think it'd be cool if they named each of the fleet Death Star 1, Death Star 2, etc....sounds like a bit more psychological impact behind it.

Mikko    How to counter?   2/16/2010 7:46:08 AM
I'm worrying here whether all my ICBM's go obsolete after this thingie gets proper funding. Could anyone give me some hints on how to coat my missiles with something that either absorbs or reflects the beams directed to it?
 
I just hurried to fit my nukes inside disco balls but they can be delivered only through trends in popular music.
 
I also tried to mount fundamentalist teenagers with pocket mirrors on my missiles but they tend to drop off on launch. Figured they could shoot back at the jumbojet.
 
Seriously, shouldn't the pro's here also give light to some counter measures for this laser? Maybe the problem with the system isn't anything considering it's functioning but how easily it can be countered.
 
I'm first to admit complete ignorance in this field of technology to even find out myself.

Pretty please, dear Chief 'Steps On A Lego' ?
