In the U.S. Navy, pay grades for officers are:
In the event that officers demonstrate superior performance and prove themselves capable of performing at the next higher pay grade, they are given an increase in pay grade. The official term for this process is a promotion.
Commissioned naval officers originate from the United States Naval Academy, the United States Merchant Marine Academy, Naval Reserve Officer Training Corps (NROTC), Officer Candidate School (OCS), the since-disestablished Aviation Officer Candidate School (AOCS), and a host of other commissioning programs such as the "Seaman to Admiral-21" program and the limited duty officer/chief warrant officer (LDO/CWO) selection program. There are also a small number of direct commissioned officers, primarily staff corps officers in the medical, dental, nurse, chaplain and judge advocate general career fields.
Commissioned officers can generally be divided into line officers and staff corps:
See also commodore (United States)—today a title for selected URL captains (O-6) in major command of multiple subordinate operational units, and formerly a rank (O-7).
The Act of Congress of March 4, 1925, allowed officers in the Navy, marine corps, and coast guard to be promoted one grade upon retirement if they had been specially commended for performance of duty in actual combat. Combat citation promotions were colloquially known as "tombstone promotions" because they conferred all the perks and prestige of the higher rank including the loftier title on their tombstones but no additional retirement pay. The Act of Congress of February 23, 1942, enabled tombstone promotions to three- and four-star grades. Tombstone promotions were subsequently restricted to citations issued before January 1, 1947, and finally eliminated altogether effective November 1, 1959. The practice was terminated in an effort to encourage senior officer retirements prior to the effective date of the change to relieve an overstrength in the senior ranks.
Any officer who actually served in a grade while on active duty receives precedence on the retirement list over any tombstone officer holding the same retired grade. Tombstone officers rank among each other according to the dates of their highest active duty grade.
Navy officers serve either as a line officer or as a staff corps officer. Unrestricted Line (URL) and Restricted Line (RL) officers wear an embroidered gold star above their rank of the naval service dress uniform while staff corps officers, and chief warrant officers wear unique specialty devices.
