. Promotion to captain is governed by Department of Defense policies derived from the Defense Officer Personnel Management Act (DOPMA) of 1980 or its companion Reserve Officer Personnel Management Act (ROPMA). DOPMA/ROPMA guidelines suggest that no more than 50% of eligible commanders should be promoted to captain after serving a minimum of three years at their present rank and after attaining 21–23 years of cumulative commissioned service, although this percentage may be appreciably less, contingent on force structure and the needs of the service. With very few exceptions, such as Naval Aviator Astronaut and Naval Flight Officer Astronaut, unrestricted line officer captains in the Navy will have successfully completed at least one commanding officer assignment at the commander (O-5) level, typically a

Others may hold command as commodores of destroyer squadrons (DESRON) or surface squadrons (SURFRONs) consisting of multiple destroyers and frigates. Surface Warfare Officers may also command large deck amphibious warfare ships or combat support ships, or serve as commodores of amphibious squadrons (PHIBRON) or other type of surface ship squadrons. In the submarine community, a captain typically commanded a nuclear-powered ballistic missile submarine (SSBN) until the early 21st century, when the requisite rank for the position was downgraded to commander. Today, like their surface warfare counterparts, captains in the submarine community may serve as commodores of submarine squadrons (SUBRON), commanding a group of SSBNs or attack submarines (SSN).

). In the Naval Special Warfare "Sea Air Land" ( SEAL) community, captains with sea commands are typically commodores in command of Naval Special Warfare Groups (NAVSPECWARGRU). In contrast, commanders of aircraft carrier strike groups (CSG) and expeditionary strike groups (ESG) are normally rear admirals, while subordinate destroyer squadron commodores, amphibious squadron commodores, carrier air wing commanders and the individual ship commanding officers within the strike group are of captain rank or lower. In addition, in the expeditionary strike group, the Marine Expeditionary Unit (MEU) commanding officer will always be a Marine Corps colonel. Adding to the confusion, all commanding officers of commissioned U.S. Navy warships and submarines (e.g., USS or "United States Ship") are called "captain" regardless of actual rank.

U.S. Coast Guard

The

also uses the same naval rank system for its commissioned officers as the U.S. Navy, with a Coast Guard captain ranking above a commander and below rear admiral (lower half). The sleeve and shoulder board insignia are similar to the Navy insignia, with a lighter shade of blue with a gold USCG shield above the stripes. Coast Guard captains follow career paths very similar to their Navy counterparts, with marine safety, security, and boat forces officers serving as Captain of the Port in command of Coast Guard Sectors, seagoing officers typically commanding large maritime security cutters or high endurance cutters and aviators commanding Coast Guard air stations. Coast Guard captains will also command all types of major Coast Guard shore installations and activities, as well as serve as chiefs of staff / executive assistants, senior operations officers, and other senior staff officers for Coast Guard flag officers. The Coast Guard has no staff corps officers. Like the U.S. Navy, all commanding officers of commissioned cutters (e.g., USCGC or "United States Coast Guard Cutter") are addressed as "captain" regardless of their actual rank.
