U.S. Navy Ranks & Insignia

In the U.S. Navy, ranks are comprised of three groups: Enlisted (E-1 through E-9), Warrant Officer (CWO-1 through CWO-5), and Commissioned Officers (CO-1 through CO-5), and Admiral ranks (CO-6 through CO-10; FADM.) The letter and number represent the rank title and paygrade of the Seaman. It’s important to note rank is different from the paygrade and signifies the level of job duties and leadership responsibilities, designated by the insignia shown on the Seaman uniform. Seaman can further advance their careers by continuing education and through command and specialty opportunities.

Learn about the ranks and insignia below:

Navy Ranks and Insignias


Enlisted Sailors

Enlisted sailors are separated into three categories: Apprenticeships (E-1 through E-3), non-commissioned Petty Officers (E-4 through E-6), and senior non-commissioned Chief Petty Officers (E-7 through E-9).

Seaman Recruit (SR/E-1)

SR is the first enlisted rank upon entering the Navy and is considered an “apprentice in training.” In basic training, the SR immerses themselves in the military culture, learning fundamental skills needed for their future career in the Navy. The SR should expect to obtain an occupational field, otherwise known as a rate, which falls under five main categories: Seamen, Firemen, Constructionmen, Airmen, or Hospitalmen. The rate assignment further breaks down into specialty subcategories, such as Machinist’s Mate (MM), Sonar Technician (ST), or Hospital Corpsman (HN). These roles are defined as the SA pursues their studies.

Army Private E-1 (PV1)

Seaman Apprentice (SA/E-2)

Once a rate is assigned, a recruit becomes a Seaman Apprentice. SA is still considered a junior-enlisted rank, and the role is similar to that of the SR. The SR must begin studying at an A-School within their rating. Common labor duties continue. Promotion occurs when the sailor has completed six months of service (determined by job performance and standing record of exemplary service.)

Navy E2 Seaman Apprentice

Seaman (SN/E-3)

Seaman is the third-lowest enlisted rank before promotable Petty Officer. All basic qualifications are met. Their competency around the ship means more job responsibilities which include essential maintenance and watchstanding.

Navy E3 Seaman

Petty Officer 3rd Class (PO3/E-4)

Sailors who reach junior Petty Officer have made it to the Fleet. The PO3 maintains regular job duties, but much of what is learned in training now shifts into leadership roles. PO3’s should be self-sufficient leaders and begin mentoring junior sailors. Qualifying for extra-duty assignments above the standard job specifications, called Collateral Duties, are key to progressing in their career. Collateral Duties can either be service-related or specialized-duties (e.g., command career counselor, command equal opportunity coordinator.)

Navy E4 Petty Officer Third Class

Petty Officer 2nd Class (PO2/E-5)

The PO2 is considered a mid-grade Petty Officer. They are proven to be self-reliant leaders and do not need much oversight from their seniors. 2nd Class Petty Officers mentor junior Seamen to ensure work performance, professional development, and training. Leadership skills improve with years of experience, and those who are selected for C-School obtain technical expertise in their rate, much like studying for certification.

Navy E5 Petty Officer Second Class

Petty Officer 1st Class (PO1/E-6)

Petty Officer 1st Class is considered a high-grade Petty Officer.
