RE: Boomers... (ballistic missile submarines) ...
We currently have 4 Vanguard Class and 18 Ohio Class on patrol.
We don't have Vanguards. Those are problematic British ships. All are in port at Glasgow, one is unarmed for life extension.
We don't have 18 OH SSBNs on patrol. We have fourteen. The remainder are SSGNs. Two of which are undergoing life extension, another being rearmed with new missiles. We have, at best, three or four SSBNs on patrol.
