Navy Officer Ranks in Order: O-1 to O-10 (Full Chart)
Navy officer ranks run from O-1, ensign, to O-10, admiral: ten commissioned grades, plus a separate chief warrant officer track for technical specialists. The complete chart sits directly below, because that is what you came for. We program for sailors and commissioning candidates through our tactical athlete training programs, and the physical standard is what gates a commissioning route long before any rank reaches a collar. Under the chart you get each tier explained, the warrant officer ladder, the insignia, 2026 pay by grade, and the cross-branch equivalents. If you need the whole ladder including the rates below O-1, our Navy ranks chart covers all of it.
Navy Officer Ranks in Order, O-1 to O-10
Figure 1.17 - U.S. Navy officer ranks in order, O-1 to O-10. O-1 Ensign (ENS), one gold bar, one ½-inch sleeve stripe, division officer or training pipeline. O-2 Lieutenant Junior Grade (LTJG), one silver bar, ½-inch stripe with a ¼-inch above, division officer earning warfare qualification. O-3 Lieutenant (LT), two silver bars, two ½-inch stripes, senior division officer, small-ship department head, aircraft commander. O-4 Lieutenant Commander (LCDR), gold oak leaf, two ½-inch stripes with a ¼-inch between, department head or executive officer. O-5 Commander (CDR), silver oak leaf, three ½-inch stripes, commands a destroyer, submarine or squadron. O-6 Captain (CAPT), silver eagle, four ½-inch stripes, commands a carrier, amphibious ship or shore command. Flag ranks wear one 2-inch stripe plus a ½-inch stripe per additional star: O-7 Rear Admiral (Lower Half) (RDML), one star; O-8 Rear Admiral (Upper Half) (RADM), two stars, carrier strike group commander; O-9 Vice Admiral (VADM), three stars, numbered fleet commander; O-10 Admiral (ADM), four stars, Chief of Naval Operations or combatant commander. Below flag rank, count the ½-inch stripes; the ¼-inch stripe marks LTJG and LCDR. Roles vary by community.

Key Takeaways:
The Navy has ten commissioned officer grades, ensign (O-1) through admiral (O-10), plus chief warrant officer grades CWO2 through CWO5.
Navy rank titles do not match the other services. A Navy captain is O-6, the same grade as an Army colonel, and a Navy lieutenant is O-3, the same grade as an Army captain.
Warrant officers are technical specialists who hold a commission. The Navy does not currently appoint W-1.
Petty officers are not officers. They sit in the E-4 through E-6 pay grades and hold no commission.
Promotion from ensign to commander normally takes 15 to 17 years of commissioned service under current DOPMA targets.
Read the chart lowest to highest: pay grade first, then title. Two details cause most of the confusion. First, the pay grade and the title are separate things, and Navy titles repeat words other services use for different grades. Second, four of the ten grades are flag officers, and the star count, not the title, is how the fleet refers to them.
The insignia column above describes the grade device. Where that device appears on the uniform changes with the uniform, which is covered further down.
Junior Officers: Ensign to Lieutenant (O-1 to O-3)
Junior officers lead a division: a group of sailors and the equipment they own, from a handful to several dozen depending on the platform. A newly commissioned ensign does not run the ship. The first tour is where a new officer earns a warfare qualification and learns the plant, the aircraft or the boat from the deck plates up.
Ensign (ENS, O-1)arrives from the Naval Academy, NROTC or Officer Candidate School. If you are unsure what OCS means, start there, because it is the fastest civilian-to-commission route. Lieutenant junior grade (LTJG, O-2)follows after roughly two years, and lieutenant (LT, O-3) roughly two years after that. Promotion through O-2 and O-3 is close to automatic for officers who stay qualified, per current DOPMA guidance.
By O-3 an officer is a credible technical authority: a division officer on a second tour, a department head on a small ship, or a qualified aircraft commander. This is the tier most people are searching from, and the one where the officer decides whether to stay for a career.
Senior Officers: Lieutenant Commander to Captain (O-4 to O-6)
Lieutenant commander (LCDR, O-4) is the first senior grade. LCDRs serve as department heads on major combatants and as executive officers of smaller commands, which is the last stop before command itself.
Commander (CDR, O-5) is where command of a warship becomes real: a destroyer, a submarine, or an aviation squadron. Captain (CAPT, O-6) commands the largest units, an aircraft carrier or a big-deck amphibious ship, or runs a major shore or staff organization.
Here is the cross-branch trap. A Navy captain is O-6, equal to an Army or Marine Corps colonel, not to an Army captain. An Army or Marine captain is O-3, which in the Navy is a lieutenant. Separately, any officer in command of a ship is addressed as "captain" regardless of grade, so a commander running a destroyer answers to the same title. Both errors are common and both matter if you are writing a resume, a letter or an award citation.
Flag Officers: Rear Admiral to Admiral (O-7 to O-10)
The Navy has four flag officer grades, and the fleet talks about them in stars.
Rear admiral (lower half), RDML, O-7: one star.
Rear admiral, RADM, O-8: two stars.
Vice admiral, VADM, O-9: three stars.
Admiral, ADM, O-10: four stars.
The highest Navy officer rank in normal use is admiral (O-10). Fleet admiral, the five-star grade at O-11, was awarded to four officers during World War II and has not been authorized since, so it is a wartime grade rather than part of the current structure.
Flag selection is a different process from every promotion below it. Boards are small, the field is narrow, and the number of flag billets is capped by law, which is why the pyramid narrows hard above O-6. The specific responsibilities, protocol and billet structure of the admiral grades are a subject of their own and deserve a fuller breakdown than this chart post can carry.
Navy Warrant Officer Ranks (W-1 to W-5)
Navy warrant officers are technical specialists, not generalist leaders. The Navy grows them from within: candidates come from the chief petty officer ranks (E-7 through E-9) through the Limited Duty Officer and Chief Warrant Officer In-Service Procurement Board, arriving with 12 to 20 years in a single technical field.
The current Navy warrant officer rank structure is CWO2 through CWO5. The Navy does not currently appoint W-1. WO1 accessions stopped in the 1970s, returned briefly for cyber specialists starting in 2018, and were removed again by NAVADMIN 161/25 in July 2025, which returned the cyber warrant program to CWO2 accession from FY27 forward. Chief warrant officers hold a commission, which is why the title carries "chief warrant officer" rather than "warrant officer."
Against the commissioned ladder, warrant grades sit above every enlisted pay grade and below ensign in precedence. In practice the comparison is about function, not seniority: a CWO3 answers technical questions that an O-3 with the same time in service cannot, while the O-3 carries broader command responsibility. The four grades progress by time and performance, and CWO5 is the senior technical authority in a rating community, often advising a commanding officer directly.
Navy Officer Rank Insignia: Shoulder Boards, Sleeve Stripes and Collar Devices
Navy officer rank insignia appears in three places, and the uniform decides which one you see.
Sleeve stripes are worn on the service dress blue jacket cuff. Gold stripes encode the grade: a 1/2-inch stripe is a full stripe, a 1/4-inch stripe is a half stripe, and flag officers wear a single 2-inch stripe with 1/2-inch stripes above it. An ensign wears one stripe, a lieutenant two, a commander three, a captain four. Chief warrant officers wear a broken 1/2-inch stripe. Above the stripes, line officers wear a gold star and staff corps officers wear their corps device instead.
Shoulder boards carry the same stripe pattern on service dress white and formal uniforms, as hard boards on the shoulder.
Collar devices are the pin-on metal insignia worn on khakis, working uniforms and flight suits. These match the Marine Corps pattern: gold bar for O-1, silver bar for O-2, two silver bars for O-3, gold oak leaf for O-4, silver oak leaf for O-5, silver eagle for O-6, and silver stars for flag officers. Chief warrant officer collar devices are silver bars broken by blue enamel segments, with CWO5 carrying a lengthwise blue stripe.
Officer vs Enlisted: Why a Petty Officer Is Not an Officer
Two errors converge here, and both come from the word "officer" doing double duty.
A petty officer is not a commissioned officer. Navy petty officer ranks are enlisted grades: petty officer third class (E-4), second class (E-5) and first class (E-6), then chief petty officer, senior chief and master chief at E-7 through E-9. The one-line rule: a commissioned officer holds a presidential commission, and a petty officer does not. The word "officer" in the title signals technical and supervisory authority within a rating, not a commission.
The Navy does not use the term non-commissioned officer. In the Army and Marine Corps, NCO is a formal category. The Navy's equivalent leadership tier is the petty officer, and Navy documents say petty officer, not NCO. Searching "Navy non-commissioned officer ranks" returns Army terminology mapped onto a service that does not use it. If you mean the E-4 to E-9 leadership tier in the Navy, the correct term is petty officer, and above E-6, chief.
Practically, this matters for pay, authority and career path. Petty officers advance by exam and performance within a rating. Commissioned officers are appointed, selected by board, and carry legal command authority. The two tracks are not a ladder from one to the other, although the warrant officer and limited duty officer programs are the bridge between them, which is exactly why those programs exist. The full E-1 to E-9 breakdown is a separate chart and is covered in its own reference.
Navy Officer Pay by Rank
Officer pay is set by pay grade, not by title, and it rises with years of service inside each grade. The figures below are 2026 monthly basic pay at the "under 2 years of service" column, which is the table minimum for each grade, following the 3.8 percent raise effective January 2026.
Figure 1.2 - 2026 U.S. Navy officer basic pay at under two years of service. Monthly rates per DFAS, effective 1 January 2026: O-1 Ensign $4,150.20; O-2 Lieutenant Junior Grade $4,782.00; O-3 Lieutenant $5,534.10; O-4 Lieutenant Commander $6,294.60; O-5 Commander $7,295.40; O-6 Captain $8,751.30; O-7 Rear Admiral (Lower Half) $11,540.10; O-8 Rear Admiral (Upper Half) $13,888.50. Warrant grades: W-1 Warrant Officer 1 $4,056.60; W-2 Chief Warrant Officer 2 $4,621.80; W-3 Chief Warrant Officer 3 $5,223.30; W-4 Chief Warrant Officer 4 $5,719.80. No rate is published at this longevity for O-9 Vice Admiral, O-10 Admiral or W-5 Chief Warrant Officer 5, nobody reaches those grades inside two years. Basic pay for O-7 through O-10 is separately capped at Level II of the Executive Schedule, $18,999.90 per month for 2026, which binds at the top of the longevity table rather than at entry. Basic pay is taxable and excludes BAH, BAS and special pays; it is identical across all services at a given grade. Source: DFAS 2026 basic pay tables. Verified July 25, 2026.
Read one caveat into every row: nobody reaches O-6 with under two years of service, so the entry column is a floor, not a realistic salary. An O-4 at ten years earns considerably more than the figure shown. Basic pay is also only part of compensation, since housing and subsistence allowances are paid separately and vary by location. Basic pay tables are republished every January, so check the current DFAS table before quoting a number.
Navy Officer Ranks Compared to Army, Marine Corps and Air Force
All four services share the same O-1 to O-10 pay grade system, so equivalence is exact by grade even though the titles differ.
Figure 1.3 - U.S. officer rank equivalence by pay grade, O-1 to O-10. All six U.S. armed services share the same pay grades, so equivalence is exact by grade. The Navy and Coast Guard use one set of titles; the Army, Marine Corps, Air Force and Space Force use another. O-1: Ensign (Navy, Coast Guard) equals Second Lieutenant. O-2: Lieutenant Junior Grade equals First Lieutenant. O-3: Lieutenant equals Captain. O-4: Lieutenant Commander equals Major. O-5: Commander equals Lieutenant Colonel. O-6: Captain equals Colonel. O-7: Rear Admiral (Lower Half) equals Brigadier General. O-8: Rear Admiral (Upper Half) equals Major General. O-9: Vice Admiral equals Lieutenant General. O-10: Admiral equals General. Note the most common error: a Navy Captain is an O-6, while an Army, Marine Corps, Air Force or Space Force Captain is an O-3, three grades lower. Conversely a Navy Lieutenant is an O-3, equal to an Army Captain, while an Army Lieutenant is an O-1 or O-2. Basic pay is identical across services at a given grade, but precedence and command authority depend on position, date of rank and chain of command. O-11, Fleet Admiral, General of the Army, General of the Air Force, exists in statute as a wartime grade and is not currently held.

Two traps are worth repeating because they cause real errors on paperwork. Navy captain (O-6) equals Army and Marine colonel. Navy lieutenant (O-3) equals Army captain. If you are weighing services rather than just decoding a chart, the military officer pathways comparison lays out how each branch commissions and develops officers.
How Long It Takes to Move Through the Officer Ranks
Movement through the officer ranks is governed by law, not by ambition. Under current DOPMA promotion targets, the timeline looks like this:
Ensign to lieutenant junior grade: about 2 years of commissioned service.
LTJG to lieutenant: about 4 years total.
Lieutenant to lieutenant commander:9 to 11 years, with roughly an 80 percent selection opportunity.
LCDR to commander: 15 to 17 years, with roughly 70 percent opportunity.
Commander to captain: 21 to 23 years, with roughly 50 percent opportunity.
Minimum time in grade for O-4 through O-6 promotion is three years. The system is up-or-out: officers twice passed over for promotion at a given grade generally separate or retire rather than stay indefinitely.
Can you skip officer ranks? No. Officers move one grade at a time. The narrow exception happens at commissioning, not after: entry grade credit can start a new officer above O-1 based on prior service, advanced degrees, or professional qualification, which is why medical, dental and judge advocate officers frequently commission directly as lieutenants.
The gate nobody plans for is physical. Commissioning programs screen fitness on the way in, and the Navy PRT standards then follow you for an entire career, because a failed cycle stalls a record that a promotion board reads years later. Age is the other hard filter, and the OCS age limits by branch breakdown shows where each service draws the line. Before you commit, it is worth knowing how long OCS lasts and what the pipeline demands week to week.
If you are choosing a program to train for that gate, our military fitness buying guide walks through how to judge one, and the military fitness FAQ answers the questions candidates ask most. For the eligibility, packages and timelines side of the process, start with becoming a Navy officer.
FAQ: Frequently Asked Questions
What are the Navy officer ranks?
The Navy officer ranks are ensign (O-1), lieutenant junior grade (O-2), lieutenant (O-3), lieutenant commander (O-4), commander (O-5), captain (O-6), rear admiral lower half (O-7), rear admiral (O-8), vice admiral (O-9) and admiral (O-10). Chief warrant officer grades CWO2 through CWO5 run on a separate technical track.
What is the highest Navy officer rank?
Admiral (ADM, O-10) is the highest Navy officer rank in active use, worn as four stars. Fleet admiral, the five-star grade, was last awarded during World War II and is not currently authorized. The senior admiral billets include Chief of Naval Operations and combatant commander assignments.
Is a petty officer an officer in the Navy?
No. Petty officers hold the E-4 through E-6 pay grades and do not hold a presidential commission. The word "officer" in the title reflects supervisory authority inside a rating, not officer status. Commissioned officers start at ensign (O-1) and are appointed and promoted through selection boards.
Does the Navy have non-commissioned officers?
The Navy does not use the term non-commissioned officer. That is Army and Marine Corps terminology. The Navy's equivalent leadership tier is the petty officer at E-4 through E-6, and chief petty officer, senior chief and master chief at E-7 through E-9.
What are the Navy warrant officer ranks?
The Navy warrant officer ranks currently in use are chief warrant officer 2 (CWO2, W-2), CWO3, CWO4 and CWO5. The Navy does not appoint W-1. Chief warrant officers are commissioned technical specialists selected from the chief petty officer ranks through the LDO/CWO In-Service Procurement Board.
How long does it take to move through the Navy officer ranks?
Under current DOPMA targets, lieutenant comes at about four years of commissioned service, lieutenant commander at 9 to 11 years, commander at 15 to 17 years and captain at 21 to 23 years. Officers cannot skip grades, and minimum time in grade for O-4 through O-6 is three years.
Navy officer ranks are a legal structure, not a set of labels. Ten commissioned grades, four flag grades inside them, and a warrant officer track that exists because technical mastery is worth commissioning on its own terms. Learn the grades, then learn the two cross-branch traps, and the chart stops being confusing.
The part of this you control starts before any of it. Commissioning programs screen fitness on the way in, and the standard does not care when you decided to apply. Build the base now, on a structured plan, and arrive at the board already qualified.
