Not sure what kind of ungodly ECM array requires two huge panels to work. When most people say "ECM" they mean specifically the jammer part of it, but the jammer itself is quite small compared to the rest of the EW array, which mostly consists of detectors.Interesting that both Naval Recognition & Henry lean to ECMs for those side hull arrays. Counter-argument for VSRs is their positions are too close to the waterline, and HPM power requirements won't be met. Placing ECMs to cover the flanks and amidship complements the H/PJ12 CIWS, and HHQ-10's obstructed coverage by the SATCOM and chaff launchers. Guess it's wait & see if the covers or new hints flip guesses.
Here is an AN/SLQ-32(V)2 with no jammer:
Here is an AN/SLQ-32(V)3 with jammer:
The V2 version is basically a RWR tied in to the ship's countermeasures system (chaff, flares, etc.)
As for the V3 version, clearly the jammer is the very small pair of panels on the bottom of the SLQ-32 EW array; an identical array on the other side of the Burke allows 4 jammers to face all 4 quadrants of the ship; this IMO is what the 055's bridge wing panels are; they are about as far away from the other shipboard electronics as is possible on that ship. The rest of those doodads on the SLQ-32 array are all radar detectors. Incidentally, that central semi-cylindrical device on the SLQ-32 array looks very much like the pair of semi-cylindrical devices sitting port and starboard at the base of the 055's coms/ESM mast. In any case I don't think those large flank panels are either jammers or detectors.
As for those large flank panels being VSRs, the fact that they are closer to the waterline is not a strong argument against this since VSRs are air search radars and therefore height above waterline is less important. OTOH I don't think they are VSRs either or they would cover bow and stern quadrants as well, but they don't. I think we should be willing to widen our imagination and consider non-electronics possibilities. I'm actually half-serious when I say those could just be panel coverings for something as mundane as life raft containers.
