Here’s a model: 12x CVNs. Each CSG does 120 days at sea followed by 245 days in port for repair, refit, workup. Of those 120 days at sea, up to 30 are in transit. Each month you put a different CSG to sea, and bring another one back to homeport. So in total, you have minimum 3x CSGs in theater at any given time, with a couple others in transit. Once a month, SECDEF would potentially have the flexibility to have 5x CSGs at sea as they are crossing paths (1 outbound, 1 inbound, and 3 on station) which gives SECDEF options for how and where to send them. Sailors have a 120:245 ratio of sea to homeport annually, giving time for training, family, etc.
Thoughts?
What are you going to do when the boats go into the yards? At any time one is in RCOH (4+ years), at a minimum, plus the extensive yard time required between cruises.
