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 (SPY 7 (V1=9 RMAs?) will have as well? We still really don't know how many RMAs the Canadian SP7 (V 3) will have?? 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 Raytheon SPY 6 (V1) with fewer RMAs. In any case, I believe this is all "speculation" on Milspec_1967's part. We should know more on all this in the next coming months of 2025/2026. Cheers!
