Navy Ranks – Enlisted Sailors

Enlisted sailors are divided 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 (E-1)

E1 is the first enlisted rank upon joining the Navy and is known as an “apprentice in training.” In basic training, they immerse themselves in the military culture, learning fundamental skills needed for their future career in the Navy. The E1 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 rating assignment further breaks down into specialty subcategories, such as Machinist’s Mate (MM), Sonar Technician (ST), or Hospital Corpsman (HN).

Seaman Apprentice (E-2)

Once a rate is assigned, a Seaman recruit becomes a Seaman Apprentice. While it provides opportunities for Seamen Recruits to receive training and experience in a particular occupational field as they progress through their Navy careers, E2 is still considered as a junior-enlisted rank, and the role is similar to that of the E1. Common job duties continue. Promotion will come when the sailor has completed six months of service (determined by job performance and standing record of exemplary service.)

Seaman (E-3)

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

Petty Officer 3rd Class (E-4)

Sailors who reach junior Petty Officer have made it to the Fleet. The E4 maintains regular labor duties, but much of what is learned in training now shifts into leadership roles. E4s should be self-sufficient leaders and begin mentoring junior sailors. Qualifying for extra-duty assignments above the standard job specifications, called Collateral Duties, are the key to progressing in their career. Collateral Duties can either be service-related or specialized duties (for example, command career counselor, command equal opportunity coordinator,…)

Petty Officer 2nd Class (E-5)

The E5 is considered a mid-grade Petty Officer. They are supposed 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 at their rate, much like studying for certification.

Petty Officer 1st Class (E-6)

Petty Officer 1st Class is considered a high-grade Petty Officer. The E6 has a leadership part in a Division team, a smaller group within a Department that includes 5-50 sailors (For example, Work Center Supervisor.) They delegate tasks and handle the most complex tasks. Some responsibilities consist of managing more significant resources, such as expensive technical equipment, repair shop personnel, and large duty sections.

Chief Petty Officer (E-7)

The Chief Petty Officer is considered the “ground level” leader of the Navy. Sailors will hold the same regard for Chiefs as they do for Officers. According to the Master Chief of the Navy (MCPON), the Chief Petty Officer utilizes skills to direct sailors toward accomplishing the Navy’s mission. They work in conjunction with the Division Officer, taking care of personnel and equipment issues.

Senior Chief Petty Officer (E-8)

At this rank, the Senior Chief commands a higher level of technical and managerial expertise. They are considered as the senior technical supervisor within a rating. An E8 has more influence in the Chiefs’ Mess (a group of Petty Officers that work closely together), and have responsibility for training new Chiefs.

Master Chief Petty Officer (MCPO/E-9)

Master Chief is the most distinguished Petty Officer. They are also known as “Department Chiefs.” E9 officer is highly credentialed in their expertise and holds the most authority in large Departments. As Master Chiefs, they’re responsible for maintaining unity, communication, and cooperation in the Chiefs’ Mess.

Command Master Chief Petty Officer (CMC/E-9)

It’s a Senior Enlisted Advisor rank. CMC is the leading Chief aboard ships or shore-based units and acts as a bridge between enlisted officers and the commanding officer. As the principal enlisted advisor to the commanding officer, the CMC is supposed to create and enact operational and human resource policies.

Master Chief Petty Officer of the Navy (MCPON/E-9) 

The MCPON is considered the most senior Enlisted Senior Advisor. By and large, the MCPON represents all enlisted members and their families in the U.S. Navy. Their duties adapt according to the needs of the Chief of Naval Operations and Chief of Naval Personnel. Over the course of two years in term, the MCPON has to travel to meet with service members and their families to address the concerns and issues of the fleet.

Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff/ SEAC

The Senior Enlisted Advisor to the Chairman of the Joint Chiefs of Staff is the main advisor to the chairman and plays a vital role in decision-making for the enlisted joint force.

Navy Officers Ranks

Warrant Officers
