UNSC Fleet Command

Were you looking for the Covenant FLEETCOM or the UNSC FLEETCOM communications channels? UNSC Fleet Command, colloquially known as FLEETCOM, is the primary operations group of the United Nations Space Command Navy, responsible for ship deployment, mission structures, and space operations. It is subordinate to the UNSC Naval Command. All naval vessels report through FLEETCOM and the commanding admirals of the UNSC.

FLEETCOM has two known headquarters, one on the planet Reach in New Alexandria, and another in Sydney, Australia, on Earth.

History
FLEETCOM has participated in nearly every UNSC space battle to date in some way. either minor or major. FLEETCOM designates orders to UNSC fleets during interstellar warfare operations.

In 2517, FLEETCOM Headquarters on Reach ordered Lieutenant Jacob Keyes to pilot the Han for Dr. Catherine Halsey to evaluate the SPARTAN-II candidates.

During the Fall of Reach, FLEETCOM HQ commanded over 150 vessels of the Epsilon Eridani Defense Fleet as well as the twenty Orbital Defense Platforms when the Covenant Fleet of Particular Justice invaded the colony. Nonetheless, Reach was glassed, with FLEETCOM HQ being one of the first headquarters to fall.

FLEETCOM Sectors
A sector is a region of space as identified by the United Nations Space Command. Sectors usually contain several star systems, some of which contain UNSC colony worlds. Other sectors contain no planets at all.

The UNSC Navy designates sectors as "FLEETCOM Sector (number)" to denote the division of command the sector's inhabitants fall under. Other sectors are simply designated "Sector (letter)-(three numbers)".

There are three known FLEETCOM Sectors:
 * Sector One - This sector of UNSC-controlled space includes the colonies and planets of the Epsilon Eridani, Tantalus, and Lambda Serpentis systems. UNSC naval forces there were commanded by Admiral Roland Freemont Fall of Reach in Summer 2552. Sector One's forces were ordered to defend Reach at all costs.
 * Sector Three - This sector of UNSC-controlled space includes the Sigma Octanus System. Commanded by Admiral Hieronymus Michael Stanforth in 2552, this sector was the site of the Battle of Sigma Octanus IV, one of the UNSC's few major victories against the Covenant.
 * Sector Four - This sector of UNSC-controlled space includes the Eridanus system. During the decision process for SPARTAN-II candidates, Dr. Halsey visited the system to observe John-117 a few months before he was abducted.

Fleet ships
FLEETCOM controls a variety of different types of ships and vessels, each designed and utilized in battle-specific roles in interstellar warfare. Below is a comprehensive listing of some of the types of vessels that are incorporated in a standard UNSC fleet:


 * Frigate - These relatively small and lightly armed ships typically escort larger vessels.


 * Destroyer - Similarly to frigates, UNSC destroyers also provide escort for larger ships, though they are more capable of direct combat.


 * Carrier - A small amount of these massive ships that deploy fighter ships and groundside troops can be seen in a standard UNSC fleet.


 * Cruiser - A handful of these gigantic, heavily armed, and heavily armored capital warships that emphasize armor and weaponry over fighter/troop deployment can be seen in a standard UNSC fleet.
 * Marathon-class cruiser - These cruisers are the primary vessels in many UNSC task forces and fleets. They are heavily armed and heavily armored.
 * Halcyon-class cruiser - These cruisers were largely obsolete by the outbreak of the Human-Covenant War, and many were scrapped.


 * Prowler - Prowlers serve as electronic warfare and intelligence gathering vessels, as well as mine layers. One prowler is assigned to each UNSC fleet and battlegroup.
