Yes, how many RMAs for each country is a "head-scratcher" you bet with all; LM and the SPY 7 (V1, V2, & V3) countries are keeping that fact "close to their vest".

On the topic of the number of RMA in the different SPY-7 radar variants ...

I note a user by the name "Milspec_1967" wrote in a German language forum ( German language reference: https://forum-sicherheitspolitik.org/showthread.php?tid=5492&pid=242434#pid242434 ) : "SPY-7(V)1 that will go on Canada's FSC uses 9 RMA's and SPY-7(V)2 that will go on Spain's F110 uses 12 RMA's." (Google translation)

That was partly corrected by user by handle "Ottone" ( German language reference: https://forum-sicherheitspolitik.org/showthread.php?tid=5492&pid=242472#pid242472 ) who stated: "Not correct: SPY-7(V) 3 comes on the Canadian River class and is the smallest variant, while SPY-7(V)1 was ordered by Japan and represents the largest maritime configuration." (Google translation)

I have no idea as to where user "Milspec_1967" obtained their numbers of RMA from. Given the names of the variant SPY-7 (v)1 was inaccurate in Milspec_1967's initial post (where v(3) added later noted as a correction by user Ottone), I don't know whether to believe such. Further no reference was provided.

Hello "oldcpu". Don't know where "Milspec_1967" is getting his "unsubstantiated" info from, but if correct, it makes some sense as the CSC River Class Destroyers come on-stream. It was always about Canada's "destroyers" saving weight on the Integrated Mast of the River Class vs better ranges so that maybe the "trade-off" for Canada. Don't know what a SPY 7 RMA weighs but I'm sure not more than what the Mast can handle. 3 more RMAs for the River Class RMA "cluster" panels should be suitable to achieve ranges required. Perhaps Canada is also doing this to save $$ as well or perhaps more RMAs will be added in "Batch II" River Class Destroyers. He does not explain how many RMAs the Japanese Mogami Class Frigates will have as well? Or perhaps his "theory" of "More RMAs= More power requirements has merit and Canada may need to upgrade it's Generators IOT handle More RMAs. Or perhaps LM has found a way to reduce the RMA numbers (technically) with less power O/P to over-come the RMA power "thingie". In My Opinion (IMO) I believe LM has found a way so that the SPY 7 can out-perform the Ratheon SPY 6 (V1) with fewer RMAs. In any case, I believe this is all "speculation" on his part. We should know more on all this in the next coming months of 2025/2026. Cheers!
