United Nations Navy

The **United Nations Navy (UNN)** is the naval branch of the United Nations military. It is considered the most powerful fleet in the system, if less technologically advanced than the fleets of some paramilitary megacorporations. Together with the United Nations Marine Corps it is the dominant military force of the Sol system. Most of the navy's military forces are spread throughout the solar system, overseeing and protecting Earth's interests in the Belt and the outer planets and generally keeping the peace.

The fleet consists of an array of capital ships (Dreadnoughts and Battleships) and a significant larger support force of smaller vessels (Cruisers, Destroyers, Frigates, Corvettes, Patrol Torpedo boats, and other general fleet support ships). On top of this, it contracts various paramilitary organisations to bolster its forces when needed, making it by far the most all-encompassing presence in the solar system.

## Structure

The UNN is divided into several established fleets, each commanded by an Admiral. Each fleet has its assigned area of responsibility. For example, the Third Fleet's area of responsibility is Jupiter and its moons; hence, it's known as the "Jupiter Fleet". However, in times of war, this division becomes rather fluid. For the purpose of executing various missions, the Navy creates temporary units of lesser size, which may consist of ships from different fleet. These units are called Task Forces.

The Secretary-General of the United Nations is the commander-in-chief of the UNN, and issues orders to the navy at large. From there, the rank structure (in descending order) of the United Nations Navy is as follows:

* **Fleet Admiral:** In control of the navy as a whole, second in command only to the Secretary-General. Usually only designated in wartime or during larger scale operations that involve multiple fleets.
* **Admiral:** In charge of a single fleet (and usually of task forces when necessary). Has the responsibility of managing multiple ships and controlling the security of the assigned region for the fleet.
* **Vice Admiral:** Second in command to the Admiral of the fleet, assisting with administrative tasks and serving as a deputy and general assistant in the management of the fleet, both in combat and out.
* **Captain:** Serves as a commanding officer of major commands such as capital ships, cruisers, or destroyer squadrons.
* **Commander:** Serves as a commanding officer of minor commands such as frigates, individual destroyers, and other fast-attack ships.
* **Lieutenant:** Serves as a department head or executive officer on an individual ship, generally second-in-command to the captain of the ship.
* **Junior Lieutenant:** Serves as a lieutenant in training on more minor commands, generally serving in this position for two years before promotion.
* **Ensign:** The initial commissioned officer rank held by graduates of the naval academy on the officer line. Generally, most ensigns are in training for their respective warfare or staff specialties. Others, serving in the fleet, are division officers.
* **Petty Officer:** A graduated sailor that holds regular job duties aboard a ship. Should generally be self-sufficient leaders and are typically tasked with mentoring junior sailors.
* **Seaman:** The lowest rank aboard a ship, generally just out of training and tasked with the general labour around the ship. Usually have specialties that they were trained in during basic training.
* **Recruit:** The first enlisted rank upon entering the Navy, considered an “apprentice in training.” In basic training, the recruit immerses themselves in the military culture, learning fundamental skills needed for their future career in the Navy.
