#2With rockets I'm guessing that thermal signatures are used to home in on the projectile being destroyed. But I'm wondering what's being used here to keep the laser locked onto the target projectile. It's definitely an impressive technological feat.

The arrow missile system uses the Israeli green pine radar for acquisition and tracking while the arrow interceptor has both passive ir and active radar tracking.

#4This tech will be the end of MAD and the start of WW3. The only thing holding back current super powers from direct confrontation are ICBMs and MAD. Once they can be reliably shot down via lasers, then full scale war is much more likely. I understand the current tech is for much slower, much lower rockets and cruise missiles. But the tech will evolve and get better. Israel is the current test bed for high tech defense, so expect further improvements over the next decade. We have seen a century of relative peace, enjoy it while it lasts.

My (completely unsubstantiated) guess is that a targeting IR laser is used for the required granularity of target correction.

Typically you'd use radar to detect incoming projectiles, using multiple detections over time to determine the trajectory of an incoming missile (they are usually unguided and will thus follow a predictable ballistic trajectory).

As long as EMPs are viable MAD is still in effect.

But would it not be possible to build missiles that can intelligently alter route upon detecting detection ? I recall once working on a auto guided industrial machine based on Motorola 68000 microprocessor that could figure out how to route itself to its destination. So unless you can detect and eliminate the missile almost simultaneously, an intelligent missile could throttle it's velocity etc. to avoid predictable trajectory.

No system, even THAAD is 100% reliable. And nothing ever has been tested in the battlefield. Statistical significance of extreme levels is needed to eliminate MAD. Also, we shouldn’t be too reliant on MAD theory to avoid developing defense tech. If we don’t, it’s a guaranteed SAD (Self-assured destruction :-) ).

AFAIK shooting down warheads will always be harder than launching them. Unless your system is really reliable, it can be bypassed by simply launching more missiles.
