First-class summer

First-class cruises occupy a minimum of eight weeks, which can be spent on a surface ship or submarine or with an aviation squadron. Mids considering the Marine Corps can spend four weeks in an officer candidate course at Quantico and another four weeks with a Fleet Marine Force unit. Selected Mids can substitute a four-week internship for half of their eight weeks. Opportunities as a detailer and to attend summer school are also available.
