Yes, but SCS has modelled the non-COTS version of Western platforms.
I can't change that without altering the interface heavily and making the western platforms so VASTLY superior to the russian units that it wouldn't be worth playing much... my guess is with full COTS implimentation, the US acoustic superiority over the Russians is probably at least as great as during the height of the Cold War pre-Sierra class.
But again, I'm wildly speculating...
