What is their command structure?
The Navy is one component of the Department of the Navy, (the Marine Corps is the other component).
It has one of the more complex command structures out of all of the US armed forces.
The Navy is broken into a dual command structure including an administrative structure and an operational structure.
The purpose of this is to alleviate operational commanders from administrative functions that might inhibit their ability to fully focus on commanding combat forces.
The administrative organization is responsible for training, research, maintenance, personnel, and supply chain.
The administrative organization begins with the Secretary of Defense and is followed by the Secretary of the Navy, the Chief of Naval Operations (CNO), and then the Commanders in Chief along with the Commander of the Naval Reserve Force.
The types of commands include:
- Shore Command- Installations that are on-shore who complete supporting operations such as repairs, training or medical.
- Systems Command- 5 Commands that assist with technical requirements
- Type Command- This command supports personnel, training, and repair on Navy fleets. This can be broken down further into smaller command types.
The Secretary of Defense issues orders to the combatant commands, who then issue orders to the component commanders.
The component commands include the Pacific Fleet, Naval Forces Central Command, Fleet Forces Command, and Naval Forces Command.
Component commanders control numbered fleet commanders.
Numbered fleet commanders command ships, submarines, and aircraft known as fleets.
There are six fleets in the Navy that are divided into task forces, task groups, task units, and then task elements.
The Navy also has squadrons for aviation units and Naval Construction Battalions (SeaBees).

This provides support and protection for ground troops below.
The USAF also has space operations that allow for missile warning, GPS, Space Situational Awareness, and to protect communications.

Navy vs. Air Force: 5 Key Differences
Difference #1: Responsibilities
Probably the most recognizable difference between the Navy and the Air Force is their responsibilities.
The Navy is responsible for protecting ports and the sea.
It consists of deployable ships and other water vessels.
Air Force members protect the sky and space.
Their force is made of mostly aircraft.
Both the Navy and Air Force will have ground positions on soil, but their main responsibilities are elsewhere.
They will both have positions that are in fields such as medic and policing and both have aircraft pilots.
But even with similar career fields, the responsibilities of those specific individuals are different.
The Air Force is known for its medical evacuation by aircraft.
While the Navy has positions in naval cyber warfare, protecting cyberspace is one of the key responsibilities given to the Air Force.
Even though their responsibilities differ, they will work together when needed.
Difference #2: Command
Another difference between the Air Force and the Navy is their command structure.
The active duty components of each branch fall under Title 10 of the US Code, but that may be all that is similar between their command structures.
The Air Force has a command structure that is similar to that of the Army.
Individuals in the Air Force fall under different commands, depending on their specific job.
They are organized using squadrons that are based on job function.
The Navy’s command is broken into two different functions: operational and administrative.
Navy members can actually fall under both commands simultaneously.
Operational commands consist of combatant commands that have primary duties of operations and exercises.
Administrative commands consist of commands that have the primary duty of all administrative functions such as training, repairs, and medical.
The Air Force commands all fall under the same structure, while the Navy breaks it into two separate commanding units to allow operational commands to focus on operation duties without the distraction of administrative functions.
Difference #3: Fighter Pilots
Despite the Navy having the main responsibility of protecting the US at sea, they also have fighter pilots.
Fighter pilots in the Navy are not the same as fighter pilots in the Air Force.
The training to become a fighter pilot in the Navy is shorter than training in the Air Force.
A large difference in fighter pilot training is that Navy members must become skilled in landing and taking off from an aircraft carrier.
Fighter pilots in the Navy and Air Force also fly different aircraft.

Difference #4: Promotions
Both the Air Force and the Navy follow the Congress recommendations for how many enlisted personnel can be on active duty and how many can be serving above an E-4.
For the Air Force, E-5 and above positions are competitive, and individuals must apply to open positions.
This means that an individual must take a position where someone has retired, been promoted, left for other reasons, or new positions have been allotted.
The Navy has also opened E-4 positions as competitive positions that must be applied for.
Lower promotions generally occur automatically based on time in service or time in rate, while higher ones will include a minimum time requirement in addition to testing requirements.
Additionally, the Navy does not have ranks, they are referred to as rates.
A pay grade and occupational specialty will determine an enlisted member’s rate.
An important difference in the promotional process is the ability for Air Force members to enlist at higher ranks if they agree to a longer enlistment.
This is something that is not offered in the Navy.

Difference #5: National Guard and Reserve
Another difference between the Navy and the Air Force is their National Guard and Reserve components.
The Air Force has a National Guard, referred to as Air National Guard.
Air National Guard has 54 organizations between states, territories, and the District of Columbia.
The Navy does not have an official National Guard component.
Both the Navy and the Air Force have reserve components.
There are several differences between the reserve components including size, base locations, and specific jobs.
It can be difficult to make a decision between the Navy vs. Air Force.
The Navy mainly supports operations in the sea but has a large air component as well.
The Air Force is responsible for protecting the United States through air operations, cyberspace, and space.
Above, we discussed what each branch does, what their responsibilities are, their size and their command structure.
Just as important, is the differences between the two branches.
Understanding what each branch does and what their differences may be will help make an informed decision on your future.
