This all sounds great to me, except for what you told me about the wire lengths. Since the proposed mod measures the distance from the launch point, a sub that is running will get a few extra miles of guidance, and a sub following the torp or resteering it at a nearby target will get ripped off.
I'd a bit worried about a 40 knot UGST at 600m trying to catch a 37 knot Seawolf, but with the advanced control mod, this might not be an issue that can't be dealt with tactically.
Is the UMP-1UE electric?
