Why sea-going officers leave as command posts shrink

As officers reach commander, captain, and flag rank, the available jobs become increasingly staff-heavy. The career path moves from generalist training into departmental specialization, then back toward general command, with staff appointments increasingly dominant at senior ranks. Those who joined to command at sea may retire when promotion offers years of paperwork and few operational posts. A small service also has little room to accommodate an officer who refuses a major command such as an SSBN, because moving that person into another scarce post displaces the officer already prepared for it. Carrier groups, escort groups, and amphibious task groups can provide senior seagoing appointments that use and retain operationally minded officers. Fleet size therefore shapes the careers and leadership culture the Navy can sustain.
