US Naval Officer Ranks: Grades, Insignia, and 2026 Pay

US Navy officer ranks run through ten commissioned grades, from Ensign (O-1) at the entry level up to Admiral (O-10) at the top, plus four active warrant officer grades from Chief Warrant Officer 2 (W-2) through Chief Warrant Officer 5 (W-5).¹ Each grade carries specific responsibilities, pay, and insignia, and together they shape everything from a small division aboard a destroyer to command of a numbered fleet.

The Commissioned Officer Grades at a Glance

O-1: Ensign (ENS)
O-2: Lieutenant (junior grade) (LTJG)
O-3: Lieutenant (LT)
O-4: Lieutenant Commander (LCDR)
O-5: Commander (CDR)
O-6: Captain (CAPT)
O-7: Rear Admiral (lower half) (RDML)
O-8: Rear Admiral (RADM)
O-9: Vice Admiral (VADM)
O-10: Admiral (ADM)

A five-star grade, Fleet Admiral, exists in statute but has not been awarded since 1950. Congress created it in 1944 as a temporary wartime measure, and US policy reserves it for situations where an American commander must hold rank equal to or above allied counterparts under their control.

Junior Officers: O-1 Through O-3

Every commissioned Navy career starts here. An Ensign is the entry-level grade, typically a recent graduate of a commissioning program who manages small work sections, stands watches, and learns the fundamentals of shipboard or squadron operations. A Lieutenant (junior grade) takes on broader duties as a division officer, leading a team responsible for a specific function like navigation or damage control. A Lieutenant is the senior junior officer grade, often serving as a department head on smaller ships or a division officer on larger ones, with real decision-making authority over people and equipment.

Original appointments to grades O-1 through O-3 are made by the President alone, without Senate confirmation.²

Mid-Grade Officers: O-4 Through O-6

The mid-grades are where officers move from managing sailors to leading large organizations. A Lieutenant Commander may serve as a department head on a major surface combatant or command a smaller vessel like a minesweeper. A Commander often commands a frigate, submarine, or aviation squadron, responsible for hundreds of sailors and complex weapons systems. A Captain is the most senior grade below flag rank and commands aircraft carriers, amphibious assault ships, major shore installations, or carrier air wings.

The jump in scope from Commander to Captain is enormous, and promotion is genuinely competitive. Original appointments to grades O-4 through O-6 require both a presidential nomination and Senate confirmation.²

Flag Officers: O-7 Through O-10

Flag officers are the Navy’s general officers, so named because they are entitled to fly a personal flag denoting their rank. A Rear Admiral (lower half) is the entry point, typically commanding a group of ships, an expeditionary force, or a major staff directorate. A Rear Admiral commands larger task forces or serves as a senior fleet staff officer. A Vice Admiral leads numbered fleets, major commands like Naval Air Forces, or serves as a Deputy Chief of Naval Operations. An Admiral holds the Navy’s highest active-duty grade, leading combatant commands or serving as Chief of Naval Operations.

Warrant Officers: W-2 Through W-5

Warrant officers occupy a distinct space. They are neither traditional commissioned officers nor enlisted personnel but deep technical experts drawn from the senior enlisted ranks. Federal law establishes five warrant officer grades, from W-1 through W-5, but the Navy no longer appoints anyone at the W-1 level.³ A Navy warrant officer enters as a Chief Warrant Officer 2 (CWO2) and can advance through CWO3, CWO4, and ultimately CWO5. Chief warrant officers at W-2 through W-5 are commissioned by the President and carry the legal authority of a commissioned officer within their area of expertise.

Candidates must be serving as a chief petty officer (E-7 through E-9) at the time of application and typically bring around 17 years of enlisted experience.⁴ That depth of hands-on knowledge is the point. A CWO running a ship’s engineering plant has likely spent nearly two decades maintaining and troubleshooting those exact systems. They direct the most technically demanding work in weapons systems, propulsion, electronics, and aviation maintenance.

One recent exception breaks the pattern. The Navy created the Air Vehicle Pilot warrant officer designator (737X) to operate the MQ-25 Stingray, the fleet’s first carrier-based unmanned aerial vehicle. Rather than converting from the enlisted ranks, 737X warrant officers are recruited primarily from civilian applicants at a much younger career stage.⁵ The Navy plans to build roughly 450 warrant officer billets for this program over six to ten years.

Line Officers Versus Staff Corps Officers

Two commissioned officers can hold the same grade but do very different jobs. Line officers are trained and eligible to command combat units at sea or ashore, in surface warfare, submarine warfare, aviation, special operations, and related communities. Unrestricted line officers can command any unit appropriate to their rank; restricted line officers work in fields like intelligence, information warfare, and oceanography but do not command warships.

Staff corps officers are professionals commissioned into one of eight specialized communities: Medical Corps, Dental Corps, Nurse Corps, Medical Service Corps, Judge Advocate General’s Corps, Supply Corps, Civil Engineer Corps, and Chaplain Corps.⁶ A staff corps officer holds the same grade and wears the same rank insignia as a line officer of equal seniority but commands within their professional field. A Supply Corps Captain might run a major logistics command rather than an aircraft carrier.

2026 Officer Pay by Grade

The 2026 pay tables, effective January 1, reflect a 3.8 percent raise over the prior year. Monthly base pay at the entry point for each grade:

Ensign (O-1): $4,150.20
Lieutenant (O-3): $5,534.10
Lieutenant Commander (O-4): $6,294.60
Commander (O-5): $7,295.40
Captain (O-6): $8,751.30
Rear Admiral, Lower Half (O-7): $11,540.10

Base pay climbs with both grade and longevity, so a Lieutenant Commander with 16 years of service earns considerably more than one who just pinned on. Pay for grades O-6 and below is capped at $15,408.30 per month, tied to Level V of the Executive Schedule. Flag officer pay is capped at $18,999.90, tied to Level II.¹

Officers also receive tax-free allowances on top of base pay. The Basic Allowance for Subsistence for officers in 2026 is $328.48 per month.⁷ A Basic Allowance for Housing varies with grade, dependency status, and duty station. Total compensation runs meaningfully higher than base pay alone.

Rank Insignia

Commissioned Officers

On dress uniforms, Navy officers wear gold sleeve stripes. An Ensign wears a single half-inch gold stripe. Each promotion adds stripes up through Captain, who wears four half-inch stripes. Flag officers switch to a distinctive pattern: a two-inch wide gold stripe at the base, with half-inch stripes added above it for each grade. A Rear Admiral (lower half) wears just the two-inch stripe; an Admiral wears the two-inch stripe plus three half-inch stripes above it.⁸

On service khaki and working uniforms, officers wear metal collar devices instead: gold bars for junior officers, oak leaves for O-4 and O-5 (gold and silver respectively), a silver eagle for Captain, and stars for flag officers. Line officers wear a five-pointed star above their sleeve stripes to indicate line status. Staff corps officers substitute a symbol identifying their community, such as an oak leaf for the Medical Corps or a cross for the Chaplain Corps.

Warrant Officers

Warrant officer insignia follows a different visual language. Their sleeve stripes are half-inch gold bands interrupted by breaks of bright blue, distinguishing them at a glance from commissioned officers.⁸ A CWO2 wears a single broken stripe; a CWO5 wears a half-inch stripe with a blue strip and a single hash mark. On working uniforms, warrant officers wear distinctive silver-and-gold collar bars. The 737X Air Vehicle Pilot warrant officers wear a Pegasus collar device and receive specialized aviation wings upon completing flight training.⁵

How Navy Officers Are Addressed

Junior officers are addressed by their full rank and last name: “Ensign Smith,” “Lieutenant Jones.” At O-4, it is “Lieutenant Commander” in full. Commanders and Captains go by “Commander” and “Captain” respectively.⁹

Flag address has a quirk that trips people up. Vice Admirals and Rear Admirals (upper half) are both addressed simply as “Admiral.” A Rear Admiral (lower half) is addressed as “Rear Admiral.” Context usually makes the specific grade obvious, and the shorthand avoids the awkwardness of “upper half” and “lower half” in conversation.

A few functional titles override grade-based address entirely. The commanding officer of any ship is called “Captain” regardless of actual rank, and the executive officer is addressed as “Commander.” Medical and dental officers are addressed as “Doctor.” Junior personnel address all seniors as “Sir” or “Ma’am.”
