To me, this means you have a bad firing solution in the beginning, and all of these are essentially just snapshots. You might as well just drop the wire and let them do their thing on their own. All of this adjusting and re-adjusting, it's nice to have the capability but it really means the shot was ill conceived.

If you have DEMON, then you should be able to develop an excellent firing solution. You should assume the bad guy gets a TIW call and begins evasion immediately. When your torpedo arrives where could he be? The answer is he is anywhere in a circle centered on the initial position with a radius equal to his maximum speed times the time late for the torpedo.

Now it becomes a question, for a given salvo size, what is the maximum range to target at which the entire arc subtended by his circle diameter and originating at your position at the time of firing, is covered by at least one torpedo sensor? Just inside that is your optimal firing range.

Take that distance, subtract it from your target range. That's your RTE. No sense in letting him pull a Marko Ramius on you.

This still doesn't defeat the problem of countermeasures, but it does insure that no matter what direction he runs there's going to be a torpedo there even if gets away from you on sonar.

The success of this tactic depends entirely on good TMA. If you don't shoot with an accurate range to the target, you're more likely to whiff. How much more likely depends on how big the error is.

If you have a good solution, though, it's creepy to watch in "Show Truth" how quickly the torpedoes acquire their targets. They're TOTALLY right there. I also think it's a really great way to shoot wakehomers.

For some reason, I think it actually does have some impact on countermeasures effectiveness, although I can't proove it. I suspect it has something to do with what the torpedo acquires first. With it enabling in just the right place and acquiring the target so quickly, it seems to acquire the target more often before it releases countermeasures. I dunno....
