While playing Battle of the First Salvo, I had to successfully ward off a phalanx of soviet Shipwreck and Sandbox Missiles. After knocking down the first salvo with RIM Missiles that were shot off, I then received a message stating "Weapon cannot have its target illuminated-missile is self destructing." I waited a moment for the next bunch of missiles to arrive so that I could do a Screen Image to send to you, but then magically and mysteriously, the RIM's started working once more to take out the balance of incoming missiles.

I did a quick check on WIKI in an attempt to find an explanation but did not find what I sought. Is there a particular sequence, device or platform that I should be looking as a solution to this? And would it make a difference if it is a high flying weapon like Shipwreck or a sea skimmer like Sandbox?

Your opinions would be appreciated.

This can happen under two circumstances:

1) The SAM arrives at the target location while the target cannot be illuminated by the firing ship (usually because it is sea-skimming and under the ship's radar horizon, but can also happen because of jamming, LOS breakage etc.).
2) You have more SAMs arriving at their targets concurrently than you have illumination channels. For example if you have 4 channels (Tico) and you have 6 SM-2MRs intercepting their targets, you can only illuminate for four of them. There is simply no time to paint for all.

Both of these issues stem from the fundamental philosophy of Aegis: Don't limit the number of missiles-in-air by the number of illumination channels and don't require a pre-fire lock and illumination; instead get as many SAMs in the air as possible (IIRC 24 concurrently in the case of Tico) and illuminate them as late as possible. Sometimes this can mean that illumination will be found to not be possible at the endgame and the SAM will be wasted. From the SAM operator's point of view, this is an acceptable "cost of doing business with Aegis" (and much preferrable to the pre-Aegis problems).

The USN is employing a number of solutions to these issues:
* CEC (Cooperative Engagement Capability) which essentially brings the concept of buddy-lazing to SAM engagements (you shoot, I guide)
* SM-2MR BlkIIB, which has an extra IR seeker in addition to the SARH seeker and thus can still engage the target (if it detects it on IR) even without terminal SARH illumination.
* SM-6 ERAM, which has an active radar seeker and thus does not require TSARH illumination at all.

BTW, the high-flier is SS-N-12 Sandbox [P-500 Bazalt/P-1000 Vulkan] while the sea skimmer is SS-N-19 Shipwreck [P-700 Granit].

where can I get info on the radar horizon... is there a way to display the radar range at an altitude instead of the max?

just wonder about this because flight profiles describe the generic capability of the attacker, but I still don't have info on the basic capability of the defense except max ranges...

A quick way to check the radar horizon of a unit that has a surface-search radar, is to turn on the radar. The range symbol (ring or segment) displayed on the map represents the radar horizon.

Just keep in mind that actual detection ranges are possible to be higher than this value, depending on target altitude.

Many Thanks for the quick response and the explanation. At the end of the day, the Tico and its mates shot down all of the offending incoming missiles but it had me on pins and needles for a few moments as I waited to see what happened. I guess in this instance sometimes "more can be less". (Oh, and my bad on the Sandbox and Shipwreck profiles- A little dyslexia I guess)

BTW since I shot so many missiles but there is an AOE platform in my Carrier Group, does it automatically or partially (based on what it has in its load out) replenish my weapons stores? It's not likely I'd be able to fend off another dual attack like the one I just encountered again without replacements. Meanwhile I'll try not to let any other SAG's get close enough to try!

Thanx
