The U.S. Navy boasts of an extensive array of ranks that form the backbone of the Navy’s organizational structure. US Navy ranks are an essential aspect of the Navy's everyday operations as they define the roles, responsibilities, and authority of each sailor and officer.

However, to understand US Navy ranks, it is important to understand that U.S. military rank is more than just who salutes whom. Military rank is a badge of leadership. Responsibility for personnel, equipment and mission grows with each advancement.

It is also important not to confuse US Navy ranks with paygrades, such as E-1, W-2 and O-5. Paygrades are administrative classifications used primarily to standardize compensation across the military services. The "E" in E-1 stands for "enlisted" while the "1" indicates the paygrade for that position. The other pay categories are "W" for warrant officers and "O" for commissioned officers. Some enlisted paygrades have two ranks.

US Navy ranks are divided into three categories: Enlisted ranks, warrant officer ranks, and officer ranks. The enlisted ranks are the ranks held by sailors who have successfully completed boot camp and have not completed or are not attending Officer Candidate School (OCS). They are usually in charge of carrying out orders and ensuring the smooth operation of Navy operations. The enlisted ranks are further divided into four categories, namely Seaman, Petty Officer, Chief Petty Officer, and Senior Chief Petty Officer.
