What is a Department Head in the Navy?
If you are researching Navy officer jobs, you will see “department head” often. It is a leadership job that sits between junior officer roles and senior command leadership. It is also one of the clearest signs that an officer is trusted to manage people, equipment, and mission readiness.

The Role Defined: What Does a Department Head Do?
A department head is a commissioned officer who leads one major department in a Navy unit. That unit could be a ship, an aviation squadron, a submarine, or a shore command. In plain terms, a department head owns results for a whole slice of the mission, not just one small team.
In most Navy units, department heads work directly for the commanding officer, often through the executive officer. They also coordinate closely with senior enlisted leaders, including chiefs and leading chief petty officers, to keep standards and readiness high.
Department head is a job, not a rank. Many department heads are mid-grade officers (often O-3 or O-4), but the exact grade depends on the unit type and the warfare community.
If the Navy were a company, department heads would be the leaders responsible for several teams at once. Many supervise multiple division officers and the divisions those officers lead.
Key Responsibilities
Most department head duties fall into a few big buckets. Titles and details change by platform, but the core work stays similar across the fleet:
- Readiness and performance Set priorities, track readiness metrics, and make sure the department can execute its mission today.
- Training and standards Plan training, qualify watchstanders, and enforce written procedures and safe work practices.
- Maintenance and material readiness Own equipment upkeep, inspections, and corrective actions, then push resources to the right place at the right time.
- People leadership Develop junior officers and enlisted leaders, manage evaluations, and handle discipline and accountability issues when needed.
- Planning and operations Translate the command’s plan into daily execution, including drills, evolutions, and mission planning.
- Administration and compliance Keep programs running, manage records, and follow Navy organization and administrative requirements.
Where Department Heads Work
Department heads exist across the Navy, but the department names change by unit:
- Surface ships: Common departments include operations, engineering, combat systems, and supply.
- Aviation squadrons: Common departments include operations, maintenance, safety, and administration (often called admin).
- Submarines: Department structures differ from surface ships, but the idea is the same: officers lead major functional areas tied to the mission and the ship’s systems.
- Shore commands: Department heads can lead major functional departments like operations, training, logistics, or administration.
Department Head vs. Division Officer vs. XO
These three roles work together, but they are not the same job:
| Role | What they lead | What they are accountable for |
|---|---|---|
| Division Officer (DIVO) | One division | Daily tasks, training, and readiness for a smaller team |
| Department Head | One department (often several divisions) | Readiness, programs, and performance across a much larger slice of the unit |
| Executive Officer (XO) | The whole unit (as the CO’s second in command) | Coordination and execution across all departments |
How to Become a Department Head?
Most officers do not become department heads immediately after commissioning. The department head role usually comes after an officer has shown strong performance in earlier leadership jobs, including division-level leadership.
Qualifications Needed
What it takes varies by community, but most department head selections have the same general pattern:
- Commissioning and education Officers must commission and meet their community’s education and training requirements.
- Strong performance in junior officer tours Officers typically complete early tours (often including division officer or equivalent roles) and earn strong performance evaluations.
- Warfare qualification Many communities expect officers to earn a warfare qualification before they are competitive for department head jobs.
- Leadership and technical training Some communities require formal pipelines before a department head tour. For example, Surface Warfare Officers may attend a formal department head course (see SWOS guidance such as the Surface Warfare Officer School department head curriculum).
Selection Process
The Navy fills department head billets based on the needs of the service and the officer’s competitive record. In many communities, the process includes formal screening and milestone timing guidance. Surface Warfare career guidance in the MILPERSMAN includes department head tour expectations and timing that can help officers understand the general pathway (see MILPERSMAN 1301-110).
In practice, strong performance, reliability, and the ability to lead across departments are the traits that make someone competitive.
Example: Department Heads on a Destroyer
On many Arleigh Burke-class destroyers, department heads commonly lead major departments such as:
- Operations Department Plans and executes operations, including navigation support, intelligence support, and watchstanding programs tied to the mission.
- Engineering Department Owns propulsion, electrical generation and distribution, damage control readiness, and shipboard maintenance programs.
- Combat Systems Department Operates and maintains sensors, weapons, combat system networks, and communications systems.
- Supply Department Manages supply, food service, ship’s store, and the logistics and contracting functions that keep the ship supported.
Medical support on many surface ships is led by an enlisted senior medical representative (often an independent duty corpsman), not a separate officer-led department.
Day-to-Day Life as a Department Head
Day to day work changes with the schedule, but most department heads rotate between operations, maintenance, and people leadership:
- Morning coordination Review department status, align priorities with the command’s plan of the day, and clear issues that block execution.
- Meetings and readiness reviews Run maintenance meetings, training reviews, and readiness updates that connect your department to the ship or unit plan.
- Deckplate leadership Walk spaces, observe work, and coach junior leaders so standards stay consistent.
- Admin and programs Handle evaluations, awards, disciplinary actions, and program requirements that keep the department running.
- Training and qualification work Support drills, certify watchstanders, and prepare for inspections, certifications, and major assessments.
Career Progression: What Comes After?
Department head tours often open the door to broader leadership positions. A common next step is serving as an Executive Officer and later competing for command, depending on community requirements and career timing.

To Sum It Up
A Navy department head is a commissioned officer who leads a major department and owns real readiness outcomes. It is a demanding leadership job built on trust, technical competence, and the ability to manage people and resources under pressure.
If you are tracking a long-term officer path, department head tours often mark the shift from learning how the Navy works to leading larger teams and delivering mission results.
