Well, far be it for me to interrupt a pleasant dream, but....
Please remember, while RFC has focused on the 'new stuff', there is still a limited number of "modern" warships in the SEM/Grayson inventory, and those ships are going to be called on to do
a lot of different missions to render the SL and protect their systems (and those systems that ally with them).
Just for the count, here's what the SEM and Grayson had for 'modern' (i.e., can eat Sollies lunch as long as the missiles last). NOTE: This is just before the BOM, pre-Python Lump, and pre-Oyster Bay so the numbers may have increased--but no more of these classes (or new classes) for at least several years.
SEM:
DD-Wolfhound (19), Roland (46 and building)
CL-Avalon (196 and building), Kamerling (48)
CA-SAG C (149)
BC-Agamemmon (P) (85 and building), Nike (12 and building)
SD(P)-Medusa (63), and Invictus (53 and building)
Grayson:
DD-Paul (17 and building)
CL-Disciple (52 and building)
CA-Burleson (17 and building)
BC-Courvosier(P) (40 and building)
SD(P)-Harrington (104) Harrington II (61 and building)
So in a way, we've been spoiled in that virtually all the new Nikes (Mike's orginal squadron and Oversteegen's) are in Talbott--and likely almost nowhere eles. And even if the number of Rolands were doubles in the python lump, that's still less than 100 ships.
And in a war against an 1800-world SL, they are going to be rather busy--and guarding convoys may be a mission to far.
So I can see those double squadrons of Sollie BC's ambushing a convoy, but it's protection is only a SAG-A, a couple of Disciples, and two elderly Chanson-class DD's.
IMHO as always.
