Wiliam K;  That is a very good point.  Optimization of that feature might even be a better route to go.  If one shot from a position was enough to have that position identified and destroyed by return fire (in less than a minute ?), who would dare to shoot first ?

good point, GlennA. I didn't notice the simulation reference at first glance.

Army's rocket intercept system

One interesting unmentioned fact is that if the system can track incoming well enough to hit them, it can also track well enough to locate the launch site and target it with "suitable response". The result is that an attempt to overwload the intercept system would certainly provide lots of return fire targeting information. One other detail is that the same intercepting system could also target incoming with directed energy weapons, which have a very good "hit" score Also, directed energy travels very fast.

HITTING A MISSLE WITH A MISSILE

I hate to be skeptical but hitting a missile with a missile is a daunting task----seeing is believing.  I worked in ballistic systems during my years in the Air Force and deployment speeds lead me to believe the reliability relative to "hits" would be considerably lower than would be tolerated.  Basically, show me a system and give me the hard data on the number of strikes.

What they HAVE in common is exhibited precisely in the movie "BRAZIL".  Any one who reads Design News should be required to see the movie. I'm betting that most of the readers of this column don't know about "Brazil" the world's most accurate (and entertaining) predicition of the future.

It should be required viewing for all high school and college students.

is tracking enough?

Intercept by tracking works best if the launch takes place from the target area. If these rockets are fired from a "safe" area, they will lose effectiveness. This means intercept can easily change to pursuit and that's whole new ballgame - and may add to enemy fire.

Of course, launching from the target area will surely increase the incentive to make a hit.

Not all applications require no collateral damage.  It can be handled operationally by implementing in an AO with clear fire zones.  As I staed in a previous post, CM is very unlikely for this class of target. 

More than likely adversaries would try to overwhelm the system to regain effectiveness.  This would require more of them to break cover and become targets themselves, which incidentally, is the biggest problem we have in low intensity conflict; identifying bad guys well enough to fit the ROEs.  When they finally meet criteria under the ROEs, they don't last very long.

Closing speed in this application is an order of magnitude less than BMD (the current progeny of SDI), and BMD has proven fairly successful.

Current systems like the CIWS can detect, track, and intercept artillery rounds with unguided 20mm DU or tungsten rounds.  Although it shoots 3000 rnds/min to accomplish the task, this new system uses a guided interceptor to reduce the amount of ammo expended for defense.

Lock Mart has had some issues in other areas in the past, but also a long line of successes in the missile realm (PAC-3, THAAD, ATACMS, GMLRS, Hellfire...).  Although it is ballistically launched, a guided weapon is a guided weapon.

Yes, if you read the article it has only been successful as a simulation.  Until real-life targets and real-life countermeasures work it is still pie-in-the-sky.  And collateral damage has to be zero = no non-targets destroyed.  It's too early for the posted enthusiasm.

Artillery ammunition isn't currently that sophisticated.  It is unlikely that an adversary would waste time trying on-projectile counter measures as any additional payload would require a reduction in warhead size. Ultimately an arms race in this niche would result in expensive artillery rounds that were less effective than they were originally - a win-win for us!

Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
