Flying ABL is still very immature concept... and it is not clear if it will ever be good enouth. Reflective material will work good enouth UNTIL temperature melts it - and it could give enouth time for warhead to survive. Ablative material is DESIGNED to melt under heavy load - again, giving warhead enouth time to survive. Also, keep in mind what modern warheads (and even some modern missiles) rotate itself in flight, making impossible to concentrate beam on one spot. Plus, ABM defence what work ONLY when installed on flying unit is very expencive and slow to responce (need to take off, need airfield nearby, etc.)What is the big deal? Clouds don't extend far into the troposphere. If the ABL flies above cloud level it can target the vehicle when it comes out with plenty of time for intercept. Reflective/ablative material won't work if the temperature increase melts it.
Space BASED INTERCEPTOR? Will not work as interceptor need to orbit the earth. You will need millions of interceptors to cover all areas lol. Space based laser could theoreticaly work but it will suffer the very same problem - reflective/ablative material, rotating warhead, decreasing beam focusing at large distances, etc. Plus, it is even more expencive than air-based ABM (MUCH MORE expencive).Forgive me for a rather uninformed question;
Why not space based systems? A nuclear tipped interceptor for example would't have far to go to intercept an ICBM at launch, nor would it need be so accurate.

Geostationary orbit are about 36 000 km away from earth. Maximum apogee for long range ICBM is about 1600 km, and is at middle distance from the target, not above the launching point.Is it not possible to place such an interceptor system on a geostationary orbit near say, iran?
The target of the ABL is not the warhead. There is far too much shielding there for a long distance shot to do any good. The target is the fuesalage where the most combustable fuels make it the easiest point of failure. The goal of the ABL is not a total KE kill like the SM-3 or THAADS, all they care about is knocking it out of the sky over the launch pad. If it falls back to earth that's the enemies problem as it will be over their territory. The ABL is the first component of the ABM defence network and is slated to be quite effective at what it is supposed to do.Flying ABL is still very immature concept... and it is not clear if it will ever be good enouth.

There have been some interesting concepts to deal with this problem. Some have included atmospheric blimps that would carry ABLs. As you pointed out the ranges for geosync orbit are far too great for lasers. One concept has something so simple as a large piece of tungesten with a thruster pack on it. As the ICBM reaches it's apogee the ball will collide with the rocket at 60,000 mph. Reloads for this system would be cheap, it came as part of the meteor bombardment program.Geostationary orbit are about 36 000 km away from earth. Maximum apogee for long range ICBM is about 1600 km, and is at middle distance from the target, not above the launching point.
Besides this, and fortunatly, there is still the 1967 treaty that bans weapons in space.
Let's say a space base laser could be deployed it might have problems (not easy to upgrade/modify). A ground based laser (sea based) is the ideal, as it could be moved around, serviced, upgraded, make the laser more powerful every week, the system smaller and more mobile, etc... If the technology is attained to go from space to earth, the opposite would be true.Space BASED INTERCEPTOR? Will not work as interceptor need to orbit the earth.

This is not realistic in absolutely most cases as it will require positioning ABL very close to enemy launch area. Any country capable of lauching 8000+km ICBM will be most likely capable of launching 200+km SAM, ESPECEALLY in 10-20 years when such ABL could appear. Moreover, IF laser science manage to reach that level - when ABL become effective - then the flying ABL will become first victim of its own success as it will be very easy to shot it down with ground-based laser. All in all, the money for ABL development is good spend but dont hold breath about any success soon.The target of the ABL is not the warhead.

All these steps are much easer said than done. Right now there are no sign what ABL reach any usefull status in the next 20 years.Let's say a space base laser could be deployed it might have problems (not easy to upgrade/modify).

My understanding is that GBLs has become the top priority (when it comes to Laser Defense) and ABL is secondary due to the size of the equipment, power needed, and toxic chemicals used to fire the laser. It's been tested and the results are sketchy (i don't know what the truth is). I believe the the laser system works somewhat like this (e.g. ABL):
1) missle launch detected
2) 1 tracking laser is immediately sent from plane to missile.
3a) Computer computations are made adusting for everything in the "atmosphere" temp, reflection/refration, and all the other factors... so that the laser that might have been "bent" when reaching its target is compensated for so it becomes a "straight beam." This is computer processing power.
3b) "Millions" of "small" mirrors are continuely adjusted based upon computer...
4) Second Powerful Laser is sent from plane to missile, which follows the tracking laser but it basically is meant to "burn a hole/tunnel through the atmosphere"--before turing atmosphere into plasma-- creating something like vacuum.
5) Most powerful laser is fired from plane. It follows the missile tracking laser, through "the tunnel" to the missile, which is destroyed basically on contact (I believe from all I've read, .2ms-- don't hold me to it).
6) Ideally system is reset within seconds as more missles will most likely follow.
I definitely don't think any ABL system can get passed the 6th step today.
This makes the case for GBL where one could use (in theory) 3 GBLs with 1/3 the ideal power, and aim/fire "as one unit."
High powered GBLs (if deployed) could immdiately eliminate satellites of unfriendly countries--blinding them-- and take out incoming missiles.
Again, I believe the main problem today, is the size of "equipment" needed to "power" a single laser that is itself "powerful" enough to destroy a missile over and over again.:unknown
Well, you said that in your opinion its the best all purpose air defense, but how sure are you??? Theres no evidence to support....Well,after reading up about it....i would say that its impressive, but it has to be proven in combat to actually see how capable it is(patriot), or it has to go through a series of thorough testing(arrow)....I myself would go for the S-400 Triumf. In my opinion the best all purpose air defense and misile defense system in the world (albeit needs a variant for ABM)
Over the years, the Russians have tested the S-300V against a wide array of targets. Antey officials claim that, in a recent series of tests in early 1997, the Gladiator and Giant interceptors successfully destroyed more than 60 ballistic and cruise missiles. Among the target missiles were Scud Bs modified to simulate Iraq's Al-Hussein short-range ballistic missile used in the Persian Gulf War. In a series of tests, S-300V had a single-shot kill probability of 0.4 to 0.7 against tactical ballistic missiles. An average of 1.5 to 1.75 interceptors are required to bring down a single target.Ibid.

Will it be able to beat the Israeli's arrow?There is no such thing as a 100% achievement even for the Arrow or other BMD /SAM systems. The S-300 and the S-300V have excellent probability of kills (what you were reffering to 100%) achievement. So far alot of interest has been generated for the S-400 Triumf by certain nations I cant remember which ones exactly at the top of my head. The Patriot has a way lower probability of interception than the basic S-300 series (PAC-3 and modernizations). The S-400 is estimated by Western intelligence experts as having a 0.9 PK (90%) probability of kill against manned aircraft , 0.8 for UAV's etc... (USING 9M96 missile). I hope this has been informative.
Btw heres some more information.
