Anti Missle Laser Tests Delayed

 

August 17th was supposed to be the day of the most recent testing of the MDA´s (US´s Missile Defense Agency) new Boeing 747 mounted anti missile laser system. However, a faulty cooling system prevented completion of the tests.

The laser, created by Lockheed Martin, has been in testing for a while now. Preliminary tests seem promising, as it had 50% success rate with actual military grade missiles from the get go.

Testing is scheduled to resume August 21st, where the MDA will attempt to shoot down missiles from twice the range as the previous tests. Actual ranges that the missiles are being shot down from have not been disclosed.

  Well summarized  
 
Nice job Pyronius. Haven´t seen this story anywhere else and is very informative. Kinda scary in some ways. I guess the cold war isn´t over. Why in God´s name do we need the ability to shoot down missiles when we KNOW full well that every other country that has missiles that we are afraid of can do the same thing?

  hmmm..  
 
anti-missle laser? reminds me of "Spies Like Us"... at least they´re mounting the lasers on planes though... easier to correct targetting...

....but seriously,... 50% success rate? that means 50% failure rate.... so toss a coin... heads you live, tails you lose

  ya but  
 
that´s military grade. Since the extremists will be launching erector set nukes, we should be fine. It´s like 70%. :-)

SIDENOTE: If a guy can invent a functional automated turret running from what appears to be an ancient IBM computer running some form of DOS, why can´t we invent a system that targets accurately. It´s not like it´s a bullet.. It´s not like a laser DOESN´T fire and travel at the speed of LIGHT. Boy, there must be some lazy ass programmers at lockheed martin.

I kind of thought so at first as well, but it is in the early testing phases so, 50% might not be all that bad for now.

The more counters there are to intercontinental missiles and such, the better in my opinion. Granted it´s in the US hands now, if it turns out to be successful, I don´t the concept of a "big fricken laser" is hard to copy.

  Well...  
 
@blain, beats %100 Miss rate without it ;)

Targeting is not the only issue, the fact is that the laser has to focus on an object that has no predefined trajectory and is moving VERY fast in some cases, I.E. it must locate and attempt to define that trajectory. Considering some missiles depending on type and use can fly upward of 1.2 to 1.5 miles per second no trivial task.

The plus side is the impact is instantaneous for most intents, it must however be maintained for sometimes a 1k to 1.5k MS depending on angle.

This means the target could have moved by well over a mile easily in that time.

Now imagine trying to hit something 6´ long moving that 6300+ FPS, in a 180° X 360° target field. Not knowing where it is coming from going to or even when to expect it. Further consider that proximity to the targeting device could mean a trajectory correction of millimeters or feet as the triangulation expands outward.

Kind of makes %50 look like a damn good percentage.
