Definitely more than one, maybe three... weapon capasity of these Ohio SSGN's is so big. (and surface ships needs air defense cutting down free
"cells" in VLS available for TLAMs)
I don't know with 4 you more likely have 2 patrolling around 1 pacific 1 atlantic and 1 as a wild card and 1 in port for maintanance. I doubt they
will be in maintneance / overhaul. You might be hard pressed to keep 3 on station for a long duration. But 450 cruise missiles will ruin anybodys
weekend
I would be very surprised if they maintain the Blue/Gold crew system when they were used in a strategic detterence mode.
Might not be a bad idea to have a couple of SSN's around for protection escort. Ill bet volleying off 150+ Tomamhawks will cause quite a rucus.
