I think there are multiple potential options available.
AW101 to replace the Cyclone on the River-class and MH-60R/MH-60S or AW159 for AOPS and CDC
MH-60R/MH-60S for the River-class, AOPS and CDC
MH-60R/MH-60S for the River-class and AW159 for AOPS and CDC
2 x AW159 for the River-class and singles for AOPS and CDC
...or any combination of the above.
Hopefully any decision on the MH portion would also consider the options for the Griffon replacement....with AW159 being an option on the light, crewed portion of the project and either the AW101 or UH-60 being options for the medium, crewed portion.
And what about the uncrewed portion of both the MH and Griffon replacements? Are there options that work for both? That will work in a cold weather Arctic/North Atlantic environment?
But as
@Baz had pointed out there needs to be a serious review of what we want/need from our MH and TacHel communities.
