It's all about the targeting. Whether the laser is millijoule or mega(giga)joule is beside the point. -Sean ---- Shag a Lizard

I still find a straight line way easier to calculate than a balistic curve including horizontal and vertical attrition, wind, temperature differences, initial speed, gravity, weight, density and so many other variables.

Also you have to consider reflected energy from the laser as well so as to not hit any nearby friendlies. ~Nitron.

We had, what, no one at the mutant hamster races. We had one entry for the Madam Curie look-alike contest, and he was disqualified later.

I just read this article on CNN today about a plain based laser weapon: http://www.cnn.com/2005/TECH/08/24/military.laser.reut/index.html[^] …and it got me to thinking about what I perceive as a very impractical problem with lasers on plains. Take a look at a bullet first. Not taking into account for any induced movement due to the movement of the barrel durring flight, a bullet is pretty much a fire-and-forget type weapon. The shale is ejected and goes on a trajectory independent (for the most part) of the plain that fired it. Lasers on the other hand are a bit different as I see it. Light by its very nature is very point-to-point. The beam extends from it point of origin outwards in a straight line. This seems to be to be one very big problem when it comes to targeting lasers from plains. One very small movement in any direction at the point of origin and, given any significant distance, that error is amplified many times. I am not math major by any mans here but this seems to me to be a big problem. It seems to me that a ground based laser solution fits the bill much better.

I suspect they use low intensity lasers for targetting together with iamge stabalisation so you just put the red dot where you want it. Ever seen a 56 ton Challenger II hit a target 2 miles away in mid air as it flies over a dune? OK, this was on telly but the fire control system can do it. Thats what the little bump at the end of the barrel is for. The tigress is here :-D

High energy lasers have been talked about for years in the military, and I have yet to hear of one that actually works. Maybe it's all hush-hush top secret stuff, but frankly, I doubt it. A lot of talk, a lot of wasted money. As to sighting, a laser is a heck of a lot easier to sight because the "impact" is instantaneous. So what if you miss? Your response time should be a LOT better than determining whether a ballistic shot hit the target. The other comments about gravity, etc., are right on. However, on the downside, keep in mind that light is 1) easily reflected and 2) subject to atmospheric disturbances. As to "very small movements", well that's what a gyroscope is for--to keep the laser platform rock stable. At least that's a technology that exists today. Marc My website

High energy laser systems are easy, not necessarily practical, but easy. This project[^] is closed, and "most" of the information is declassified. Tested, proven in single and salvo shots to higher accuracy than any other missile defense system I ever worked on. It's just too bulky to be practical. edit:
To date, THEL has destroyed 28 Katyusha test rockets and five test artillery shells. On May 4, 2004, THEL’s new transportable version, known as the Mobile Tactical High Energy Laser (MTHEL), tracked and destroyed a large-caliber test rocket at the U.S. Army’s White Sands Missile Range in New Mexico. The rocket flew faster and higher than the Katyushas, and carried a live warhead. The U.S. and Israel expect MTHEL to be operational and ready for deployment by 2007._________________________ Asu no koto o ieba, tenjo de nezumi ga warau.

First, your using of "plain" vs. "plane" threw me at first; I was thinking, "Why base lasers in Kansas?" One idea behind this is to have the airplane in a pattern near a battlefield or danger zone and then to use it primarily to shoot down enemy missiles during boost phase (one advantage is that the results of the destruction don't come raining down on you, causing incidental damage.) Tracking systems have gotten quite sophisticated, so I don't think this is that big of a problem. (The laser sight system on the Abrams tank is amazing.) Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke -- modifed at 12:08 Thursday 25th August, 2005

Latest Articles: Object Comparer String HelpersThey say the main reason for it being so big is the cooling system. By puting it on a plane that moves with the speed of sound in high cool air, how hard could it be to open a hole from front to back, full with hit sinks on the side? And the best part: you don't need a noisy fan!

Kastellanos Nikos wrote: how hard could it be to open a hole from front to back, full with hit sinks on the side? Uh, because air at high speed causes a lot of friction which causes a lot of heat. Ever heard about how the skin of the Concorde stretches several inches from the heat produced by the friction? Kastellanos Nikos wrote: you don't need a noisy fan! Any disturbance to the air flow at high speeds causes a heck of a lot more noise than a fan. Sonic booms, anyone? Marc My website
