The U.S. Navy’s rank system might look complicated from the outside, but it’s actually a carefully designed structure that keeps one of the world’s most powerful naval forces running smoothly. From the newest recruit to four-star admirals, every sailor has a specific place in this hierarchy that determines their responsibilities, authority, and how they’re addressed.
This guide breaks down the three main categories of Navy personnel – enlisted sailors, warrant officers, and commissioned officers – and explains what all those stripes, stars, and anchors actually mean.
How Navy Ranks Work
The Navy organizes its personnel into three distinct groups: enlisted personnel who operate and maintain ships and equipment, warrant officers who serve as technical experts, and commissioned officers who lead and command. Each group has its own promotion path and insignia system.
Every rank corresponds to a paygrade – a standardized system used across all military branches. Enlisted paygrades run from E-1 to E-9, warrant officers from W-1 to W-5, and commissioned officers from O-1 to O-10. This system ensures consistent pay and benefits regardless of which branch you serve in.
The rank structure serves three critical purposes. It establishes a clear chain of command essential for military operations. It creates operational efficiency by assigning specific duties to personnel at every level. And it provides a path for career advancement that rewards experience, leadership, and technical mastery.
Enlisted Personnel: The Backbone of the Fleet
Enlisted sailors make up the majority of Navy personnel. They operate complex weapons systems, maintain ships and aircraft, and carry out the daily missions that project American naval power around the world. The enlisted career path takes sailors from entry-level apprentices to senior leaders who mentor officers and enlisted personnel alike.
Junior Enlisted: Learning the Ropes
The first three paygrades represent the apprenticeship phase of a Navy career. New recruits enter one of five broad career fields – Seaman, Fireman, Airman, Constructionman, or Hospitalman – which determines their initial training path.
Seaman Recruit (E-1) is where everyone starts. New recruits have no rank insignia and spend their time completing basic training, learning Navy customs, and developing fundamental military skills. Most sailors spend only a few months at this level.
Seaman Apprentice (E-2) comes after boot camp. These sailors attend technical training schools to learn their specific job while also performing general duties like watch-standing and maintenance. Promotion to E-2 typically happens automatically after six months of service.
Seaman (E-3) represents basic competency in your job field. E-3 sailors are expected to be proficient in their basic skills and take on more responsibility within their work group. They’re considered qualified junior crew members who contribute meaningfully to operations.
Petty Officers: The Technical Leaders
Promotion to Petty Officer Third Class marks a major transition from apprentice to Non-Commissioned Officer (NCO). Petty Officers are the Navy’s front-line leaders and technical experts, responsible for both leading junior sailors and performing hands-on work in their specialty.
Petty Officer Third Class (E-4) is the first leadership rank. These sailors must demonstrate technical expertise while developing skills to mentor junior personnel. They’re the workhorses of the fleet, executing tasks and leading small teams.
Petty Officer Second Class (E-5) takes on greater supervisory roles with more experience and often advanced training. They’re responsible for team performance and equipment functionality under their charge.
Petty Officer First Class (E-6) serves as a key leader within their division, often as the Leading Petty Officer (LPO). They’re the primary enlisted supervisor for divisions ranging from five to over fifty sailors, managing resources, training personnel, and serving as the link between enlisted sailors and senior leadership.
Chief Petty Officers: The Mess
Achieving Chief Petty Officer rank represents one of the most significant milestones in an enlisted career. The “Chief’s Mess” – the community of Chiefs, Senior Chiefs, and Master Chiefs – is widely regarded as the backbone of the Navy.
Chiefs wear distinctive khaki uniforms similar to officers and have separate berthing and dining facilities aboard ships. This reflects their unique position bridging the gap between officers and enlisted personnel.
Chief Petty Officer (E-7) serves as high-impact leaders who translate commanding officers’ intentions into action. They ensure discipline, mentor everyone from new recruits to new officers, and serve as the undisputed technical experts in their field.
Senior Chief Petty Officer (E-8) possesses advanced managerial skills and typically serves as a department’s senior enlisted leader. They advise department heads on all matters related to personnel and equipment within their area of responsibility.
Master Chief Petty Officer (E-9) represents the highest enlisted paygrade. Master Chiefs are senior enlisted leaders at the command level and the foremost experts in their fields, with the most extensive experience in leadership and technical supervision.
Senior Enlisted Leaders
Several E-9 positions represent the pinnacle of enlisted leadership:
Command Master Chief (CMDCM) serves as the senior enlisted sailor for an entire command like an aircraft carrier or major shore installation. They represent enlisted personnel to the Commanding Officer and serve as advisors on morale, welfare, and discipline. On submarines, this position is called “Chief of the Boat” or “COB.”
Fleet/Force Master Chief (FLTCM/FORCM) serve as principal enlisted advisors to admirals commanding major fleets or force commands.
Master Chief Petty Officer of the Navy (MCPON) is the senior-most enlisted person in the entire Navy. Appointed by the Chief of Naval Operations for a two-year term, the MCPON serves as spokesperson for the enlisted force to Navy leadership and the public.
Reading Enlisted Insignia
Navy enlisted insignia tells a detailed story about each sailor’s paygrade, job, and experience. Understanding how to read these markings helps you understand the person wearing the uniform.
The Navy uses specific terminology that differs from other military branches. While other services use “rank” for everyone, the Navy reserves “rank” for officers. For enlisted personnel:
- Rate refers to the paygrade and title (like Seaman or Petty Officer Second Class)
- Rating refers to the specific job or occupational specialty (like Boatswain’s Mate or Information Systems Technician)
A sailor’s full title combines rate and rating, such as “Gunner’s Mate Second Class” or “GM2.” This system reflects the Navy’s deep cultural value placed on technical expertise. The Naval History and Heritage Command maintains a complete list of current and historical ratings.
When Navy leadership attempted to eliminate rating titles in 2016, the backlash from sailors was so strong that the decision was quickly reversed. This reaction shows how fundamentally a sailor’s identity ties to their technical craft.
Insignia Details
On dress uniforms, enlisted insignia appear on the upper sleeve:
Junior Enlisted (E-2 and E-3) wear diagonal stripes called Group Rate Marks. E-2 sailors wear two stripes, E-3 sailors wear three. The stripe color indicates their career field:
- White: Seaman (Deck and Administrative)
- Red: Fireman (Engineering)
- Green: Airman (Aviation)
- Light Blue: Constructionman (Seabees)
- White with caduceus: Hospitalman (Medical)
Petty Officers (E-4 to E-9) wear a Rating Badge, often called a “crow” because of the perched eagle at the top. The badge has three elements:
- The Eagle: Shows the wearer is a Petty Officer
- Specialty Mark: A symbol below the eagle indicating the sailor’s specific job
- Chevrons: V-shaped stripes indicating paygrade (one for E-4, two for E-5, three for E-6)
Chief Petty Officers add an arched “rocker” above the top chevron. Silver stars above the eagle denote higher paygrades: no star for CPO (E-7), one star for SCPO (E-8), two stars for MCPO (E-9), and three stars for MCPON.
Sailors with 12 or more years of continuous good conduct service can wear gold stripes instead of red – a significant mark of distinction and sustained superior performance.
Enlisted Rank Overview
| Paygrade | Rank | Sleeve Insignia | Collar Device | Key Responsibilities |
|---|---|---|---|---|
| E-1 | Seaman Recruit (SR) | No insignia | No insignia | Basic training, learning fundamentals |
| E-2 | Seaman Apprentice (SA) | Two diagonal stripes | Metal device with two stripes | Technical training, general duties |
| E-3 | Seaman (SN) | Three diagonal stripes | Metal device with three stripes | Basic job proficiency, increased responsibility |
| E-4 | Petty Officer Third Class (PO3) | Eagle, specialty mark, one chevron | Eagle on fouled anchor, one chevron | First leadership position, team leading |
| E-5 | Petty Officer Second Class (PO2) | Eagle, specialty mark, two chevrons | Eagle on fouled anchor, two chevrons | Supervisory roles, team performance |
| E-6 | Petty Officer First Class (PO1) | Eagle, specialty mark, three chevrons | Eagle on fouled anchor, three chevrons | Division leadership, resource management |
| E-7 | Chief Petty Officer (CPO) | Eagle, specialty mark, chevrons and rocker | Gold fouled anchor with “USN” | Bridge between officers and enlisted |

| E-9 | Master Chief Petty Officer (MCPO) | Two stars, eagle, specialty mark, chevrons and rocker | Gold fouled anchor with “USN” and two stars | Command-level senior enlisted leader |
Warrant Officers: The Technical Experts
Warrant Officers occupy a unique position in the Navy’s leadership structure. These commissioned officers are former senior enlisted personnel selected for their exceptional technical expertise and leadership potential. They serve as the Navy’s premier technical specialists, bridging the gap between enlisted personnel and traditional officers.
The Warrant Officer Path
The Warrant Officer ranks progress from W-1 to W-5. The W-1 rank (Warrant Officer 1) was discontinued for many years but officially reinstated in 2018 for the highly specialized cyber warfare community, showing the Navy’s flexibility in meeting modern technological demands.
- Warrant Officer 1 (WO1) – W-1
- Chief Warrant Officer 2 (CWO2) – W-2
- Chief Warrant Officer 3 (CWO3) – W-3
- Chief Warrant Officer 4 (CWO4) – W-4
- Chief Warrant Officer 5 (CWO5) – W-5
The “Mustang” Role
Warrant Officers are often called “Mustangs” – a term of respect for those who have “come up through the ranks” from enlisted service. To be considered for the program, sailors typically must be senior enlisted members (E-6 or above) with extensive service (often 12-14 years or more) and proven records of technical mastery and leadership.
Their primary function is serving as technical experts, leaders, and mentors within specific occupational fields. They possess the authority and knowledge to direct the most difficult and complex operations within their specialty. While their focus is technical, their leadership scope is broad – they may serve as division officers, department heads, or even Executive Officers or Commanding Officers of smaller units.
Each Warrant Officer specialty has a unique four-digit designator code, such as 711X for a Boatswain or 784X for a Cyber Warrant Officer. MyNavy HR maintains current designator lists.
Why Warrant Officers Matter
The history of the Warrant Officer program reveals its essential nature. The program was briefly phased out in the mid-20th century, with the belief that Master Chiefs and Limited Duty Officers could fill the void. This experiment failed because Master Chiefs lacked the statutory authority of commissioned officers, while LDOs often moved into broader management roles, losing direct connection to equipment and personnel.
The program’s reinstatement demonstrated that the Navy has a persistent need for officers defined by deep, sustained technical expertise rather than generalized command preparation.
Warrant Officer Insignia
Warrant Officer insignia are unique, visually distinguishing them from both enlisted personnel and other commissioned officers.
Collar Devices feature metal bars worn on collar points. The color and number of breaks indicate grade:
- WO1: Gold bar with one horizontal blue break
- CWO2: Gold bar with two horizontal blue breaks
- CWO3: Silver bar with two horizontal blue breaks
- CWO4: Silver bar with three horizontal blue breaks
- CWO5: Silver bar with one wide horizontal blue stripe
Sleeve and Shoulder Board Insignia on dress uniforms feature gold stripes of varying widths. Unlike other officers’ solid stripes, CWO sleeve insignia have breaks of blue fabric within the gold stripe corresponding to their grade.
Commissioned Officers: The Command Structure
Commissioned officers hold commissions from the President of the United States and are responsible for overall leadership, strategic planning, and command of Navy ships, aircraft, submarines, and shore installations. Their ranks are confirmed by the U.S. Senate.
Junior Officers: Building Leaders
Junior officers are developing their leadership and warfare skills while learning to command at increasing levels of responsibility.
Ensign (O-1) represents the entry-level commissioned rank, typically held by graduates of the Naval Academy, NROTC programs, or Officer Candidate School. Ensigns usually serve as division officers on ships, leading enlisted sailors under senior officer guidance.
Lieutenant Junior Grade (O-2) comes after approximately two years of service. LTJGs continue as division officers but with greater responsibility and less supervision.
Lieutenant (O-3) represents a fully qualified warfare officer. Lieutenants are seasoned division officers on large ships or may serve as department heads on smaller vessels. They play key roles in mentoring junior officers.
Lieutenant Commander (O-4) serves as a mid-level leader, often as department heads on large ships (like Engineering Officer or Operations Officer). They may serve as Executive Officers on smaller ships or Commanding Officers of small vessels like minesweepers.
Senior Officers: The Commanders
Senior officers hold major command and staff positions with significant leadership responsibilities.
Commander (O-5) holds significant leadership positions as Commanding Officers of smaller ships (frigates, destroyers, fast-attack submarines), aviation squadrons, or shore installations. On larger ships, they often serve as Executive Officers.
Captain (O-6) represents a highly prestigious rank with major command responsibilities. Captains command the Navy’s largest warships including aircraft carriers, cruisers, and ballistic missile submarines. They also command carrier air wings, destroyer squadrons, and major shore installations.
Flag Officers: The Admirals
Flag Officers are the Navy’s senior executives, responsible for strategic direction and command of vast naval forces. Their title comes from the tradition of flying a flag from their command ship.
Rear Admiral Lower Half (O-7) is a one-star admiral who may command an amphibious group, expeditionary strike group, or serve as deputy commander in larger organizations.
Rear Admiral (O-8) is a two-star admiral who often commands Carrier Strike Groups or holds senior strategic positions within the Department of the Navy or Defense.
Vice Admiral (O-9) commands entire numbered fleets (like U.S. Fifth Fleet in the Middle East) or serves as deputies for major regional commands. Current flag officer biographies are available on the Navy’s website.
Admiral (O-10) represents the highest permanent Navy rank. Admirals hold the most senior operational commands like U.S. Pacific Fleet or U.S. Naval Forces Europe-Africa, and serve in the Navy’s highest positions including Chief of Naval Operations.
Fleet Admiral (O-11) is a five-star rank only authorized during wartime. It hasn’t been held since World War II, when it was bestowed on naval legends like Chester Nimitz, William Leahy, Ernest King, and William Halsey.
Officer Insignia Systems
Navy officer insignia vary significantly depending on the uniform, reflecting deep naval traditions.
Sleeve Stripes on the formal Service Dress Blue uniform feature gold stripes on the lower sleeves – a tradition inherited from the British Royal Navy. Rank is indicated by the number and width of stripes. For example, a Lieutenant wears two half-inch stripes, while a Captain wears four half-inch stripes.
Shoulder Boards on the Service Dress White uniform display the same stripe patterns on hard shoulder boards called epaulettes.
Collar Devices on less formal uniforms like Service Khaki and working uniforms feature pin-on metal insignia on collar points, similar to other military branches:
- Bars: Ensign (one gold), LTJG (one silver), Lieutenant (two silver)
- Oak Leaves: Lieutenant Commander (gold), Commander (silver)
- Eagle: Captain (silver)
- Stars: Rear Admiral Lower Half (one silver), Rear Admiral (two), Vice Admiral (three), Admiral (four)
Staff Corps Distinction: Line Officers eligible for command of warships wear a gold star above their stripes. Staff Corps Officers who are specialists in fields like medicine, law, or supply wear unique corps devices instead. Medical Corps officers wear a gold oak leaf with silver acorn, while Judge Advocate General (JAG) officers wear a millrind symbol.
Officer Rank Overview
| Paygrade | Rank | Collar Device | Sleeve Stripes | Command Responsibilities |
|---|---|---|---|---|
| O-1 | Ensign (ENS) | One gold bar | One half-inch stripe | Division Officer in training |
| O-2 | Lieutenant Junior Grade (LTJG) | One silver bar | One half-inch, one quarter-inch stripe | Division Officer, increased responsibility |
| O-3 | Lieutenant (LT) | Two silver bars | Two half-inch stripes | Experienced Division Officer; Department Head on small vessels |
| O-4 | Lieutenant Commander (LCDR) | Gold oak leaf | Quarter-inch between two half-inch stripes | Department Head on large ship; XO/CO of small ship |
| O-5 | Commander (CDR) | Silver oak leaf | Three half-inch stripes | CO of destroyer/frigate/submarine; XO of large ship |
| O-6 | Captain (CAPT) | Silver eagle | Four half-inch stripes | CO of aircraft carrier/cruiser/major installation |
| O-7 | Rear Admiral Lower Half (RDML) | One silver star | One two-inch stripe | Commander of Strike Group/Amphibious Group |
| O-8 | Rear Admiral (RADM) | Two silver stars | Two-inch stripe with half-inch above | Commander of Carrier Strike Group; strategic staff |
| O-9 | Vice Admiral (VADM) | Three silver stars | Two-inch stripe with two half-inch above | Commander of numbered fleet |
| O-10 | Admiral (ADM) | Four silver stars | Two-inch stripe with three half-inch above | Major regional command; Chief of Naval Operations |
How to Address Navy Personnel
Properly addressing military personnel shows respect and understanding of military culture. While the rules may seem complex, a few guidelines work for most situations.
Formal Address
The safest approach is using a service member’s rank or rate followed by their last name.
Enlisted Personnel:
- E-1 to E-3: “Seaman [Last Name]”
- E-4 to E-6: “Petty Officer [Last Name]”
- E-7: “Chief [Last Name]” or simply “Chief”
- E-8: “Senior Chief [Last Name]” or “Senior Chief”
- E-9: “Master Chief [Last Name]” or “Master Chief”
Warrant Officers: “Chief Warrant Officer [Last Name]” or “Mr./Ms. [Last Name]”
Commissioned Officers:
- O-1 to O-4: Use full rank and last name (e.g., “Lieutenant Commander Smith”)
- O-5: “Commander [Last Name]”
- O-6: “Captain [Last Name]”
- O-7 to O-10: “Admiral [Last Name]”
When speaking to any officer senior to you, “Sir” or “Ma’am” is always correct and expected.
Common Navy Address
Within the Navy, less formal terms reflect the service’s unique culture.
Petty Officers are often addressed by their rating and paygrade rather than “Petty Officer” – such as “IT1” for Information Systems Technician First Class or “BM2” for Boatswain’s Mate Second Class. This reinforces the cultural importance of technical specialty.
Junior Officers are sometimes addressed as “Mister [Last Name]” or “Ms. [Last Name]” – a tradition particularly prevalent in submarine and aviation communities.
Positional Titles are common for senior officers. The Chief Engineer is called “CHENG,” the Navigator is “NAV,” and the Executive Officer is “XO.”
The Commanding Officer of any ship or squadron is often called “Skipper” or traditionally “The Old Man.”
Common Questions About Navy Ranks
What’s the difference between a Captain and the captain of a ship?
Captain (CAPT) is a formal rank with paygrade O-6. However, “captain” (lowercase) is a position, not a rank. Any Commanding Officer of a commissioned Navy vessel is called “captain” regardless of their actual rank. While an aircraft carrier’s CO will be a Captain (O-6), a destroyer’s CO is likely a Commander (O-5), and a patrol craft’s CO could be a Lieutenant (O-3).
How does an enlisted sailor become an officer?
Several paths exist for enlisted personnel to earn commissions. The Limited Duty Officer (LDO) and Chief Warrant Officer (CWO) programs are designed for outstanding senior enlisted personnel and don’t require college degrees. Other paths like Officer Candidate School (OCS) are available for enlisted sailors who have earned four-year college degrees.
What are some common Navy terms?
The Navy has unique terminology that reflects its maritime heritage:
- Bulkhead: Wall on a ship
- Deck: Floor
- Overhead: Ceiling
- Rack: Bed or bunk
- Galley/Mess Deck: Kitchen/dining area
- Head: Bathroom
- Scuttlebutt: Drinking fountain; also rumors or gossip
- Aye, Aye: Reply to an order meaning “I understand and will comply”
- Bravo Zulu (BZ): Naval signal meaning “Well Done”
Where can I find military records?
Official military service records for discharged and deceased veterans are maintained by the National Personnel Records Center in St. Louis, Missouri. You can request records online through the National Archives or by mail using Standard Form 180. For general information, visit the U.S. government’s military records portal.
Understanding Navy Culture
The Navy’s rank structure reflects more than just organizational hierarchy – it embodies the service’s core values and maritime traditions. The emphasis on technical expertise, the respect for experience, and the clear chain of command all serve the ultimate goal of maintaining the world’s most capable naval force.
Whether you’re a family member trying to understand your sailor’s career path, a civilian working with Navy personnel, or simply someone interested in military structure, understanding these ranks and insignia provides insight into how the Navy operates and what drives its culture.
The complexity of the system serves a purpose: it creates clear expectations, rewards expertise and leadership, and maintains the good order and discipline essential for naval operations. From the newest Seaman Recruit learning basic seamanship to the Admiral commanding entire fleets, every sailor knows their place in this time-tested structure that has served America’s maritime interests for over two centuries.
