The **SDF Navy** (**海軍**) is the branch of the sirius defense forces responsible for space warfare and operations, though they still operate in terrestrial oceans with their maritime arm. Its roles include space warfare, orbital bombardment, the deployment of atmospheric and space fighters, and the delivery of UNSC Marines into combat.

## Mission

The SDF Navy's mission is to *"Provide naval forces to ensure freedom of access for aerospace and terrestrial operations."* More specifically, the Navy is responsible for destroying and suppressing hostil space and sea combatants. The Navy's collateral functions include;

* transportation of SDF assets.
* Development of doctrine, procedures and equipment that are of common interest to the Air Force and Marine Corps.
* Providing forces for joint aerospace and terrestrial operations, in accordance with SDF doctrine.
* Coordination with civil agencies for the establishment and maintenance of naval depots and yards.

## Organization

The SDF Navy is subordinate to the SDF High Command. The Navy is administered by the SDF Naval Command, or NAVCOM, headed by the Chief of Naval Operations. The CNO is assisted by the Deputy Chief of Naval Operations. NAVCOM is split into three commands;

* Fleet Command, or FLEETCOM, has oversight of ship deployment, mission structures, sea and space operations, including the transport of troops and naval fighter operations. It is the largest and most powerful component of any NAVCOM grouping.
* Naval Logistical Operations Command, or NavLogCom, oversees the construction, maintenance, and distribution of supplies and matériel, including ships, ammunition, replacement parts, and food.
* Naval Special Warfare Command, or NAVSPECWARCOM, and Naval Special Weapons are responsible for all Naval special operations.

The SDF Navy also operates with UNICOM forces to form one of four Central Commands which hold responsibility over a certain area of sea and space. These territories are known as CentCom regions. Forces assigned to one CentCom region can not be moved to another without HIGHCOM approval.

The Office of Naval Intelligence is technically subordinate to the SDF Naval Command. In practice, however, ONI's activities extend far beyond intelligence gathering, and it often receives mandates and directives from HIGHCOM or even higher. ONI holds a strong presence in the SDF fleet. Despite being under the command of the Navy, ONI's Commander-in-Chief holds a seat on the Security Council with equal stature and privilege to the committee members of the Navy, Marines, Army, and Air Force.

Commanding positions in NAVCOM tend to be held by commanders. Because of their role as an amphibious and space-deployed force, the SDF Marine Corps enjoys a close relationship with the Navy, with Marine complements being deployed on most warships.

## Operating forces

SDF Navy forces are divided into a number of fleets. These tend to be large formations, though they seldom patrol together; single ships are commonly seen patrolling throughout sirius. Defense fleets were often considered to be little more than glorified revenue police. Defensive fleets typically find a smaller "tactical" carrier at their core. The SDF Navy also has several numbered expeditionary fleets.

Fleets are typically assigned to sectors.

These fleets are further divided into several battle groups, more common tactical formations which are formed on an as-needed basis and vary dramatically in size from three ships to large carrier groups with smaller tactical carriers at their core. Battle groups are flexible fighting organizations that can be "plugged together" into arranged task forces. A squadron is a group of warships that is smaller than a fleet.

## Personnel

Large numbers of women are employed by the SDF Navy. Servicepeople hold ranks, which are divided between officers and enlisted. Navy personnel are given training in self-defense. All crewwomen are trained to use handguns. Navy recruits serve in initial recruit training operated by the Unified Combined Military Boot Camp. At boot camp, recruits are trained, tested, and evaluated on their physical fitness, proficiency with firearms, and command potential. Following graduation from UCMB, a naval recruit may be required to complete additional training revolving around the vacuum of space and microgravity. Finally, a recruit is assigned aboard a naval vessel or installation as a non-commissioned recruit within the Navy. there are several Officer Candidate Schools that provide training and allows enlisted personnel or civilians to become officers.
