It consists of a main platform about the size of a heavy cruiser receiving information from many other platforms deployed through the system. It provides ~ 25,000 control links, give or take a link. But that system was pre-placed. Making it useless in enemy territory.
But Moriarty only had that many control links because:
a) Essentially the entire platform was fire control "four hundred thousand [tons] wasn't a lot . . . unless all of it was dedicated to fire control"
b) It relayed that fire control through a bunch of pre-placed platforms that were "in effect, a less capable, simpler minded version of the RMN's own Keyholes"
That second is what let it control that many missiles without wedges cutting all it's control links.
A mobile ship would not only need to carry all the normal ship things, plus all the CM launchers, plus magazines for CMs (and so be able to fit far, far, far, fewer control links per ton) but it wouldn't have all those fire control relays to disperse that fire control across and allow it to maintain the necessary lines of sight to each of its swarm of CMs.
Oh, and even with pods you can't get the kind of numbers of missiles that Moriarty enjoyed with its shoals of widely separated pre-deployed pods -- because a ship rolling pods still runs into limits on how many they can roll between incoming salvos and needing to spread them enough to provide clearance around each missiles's multi-km wide wedge. Moriarty also gets to take advantage of the fact that all its missiles were widely dispersed across predeployed shoals of pods around the system -- giving all kinds of room so wedge clearance wasn't a significant concern.
All that said, if you took an SD(P) and dedicated it to defensive fire it would be more capable and fleet defense than a normally balanced SD(P). But probably only somewhat more capable. I'd guess less than 50% more effective -- a current SD(P) can already throw and control a crazy number of CMs -- to the point where if you had two Invictus-class armed with Mk23s they'd likely be unable to land a single hit on each other. A quad-stacked salvo would sent 240 missiles at the other SD(P), which could respond with 8 full salvos from its 206 CM tubes; so 1648 CMs, nearly 7 per incoming missile!
But even if it's twice a good defensively, to get that you're giving up 100% of its offensive firepower -- firepower that helps more quickly reduce the number of platforms that are shooting back at the fleet. And it'd cost basically as much time and money to build as normal SD(P) so you're shrinking your offensive firepower significantly since you're limited in the number of ships that size you can build and operate. Every SD(CM) you has in one fewer SD(P).
Now if you were able to actually build something the size and cost of a heavy cruiser that gave you the defensive firepower of a SD(P) then it might start to make sense to build a dedicated anti-missile escort. But the way RFC set up his Honorverse I don't see how you could possible do that.
