The '''UNSC Navy''' ('''UNSCN''')<ref>'''[[Halo: Glasslands]]''', ''page 64''</ref> is the branch of the [[United Nations Space Command|UNSC]] [[UNSC Armed Forces|Armed Forces]] responsible mostly for naval warfare and operations in space, though they still operate in the oceans with their terrestrial arm. Its roles include [[Space warfare|ship-to-ship combat]]; [[orbital bombardment]]; the deployment of atmospheric and [[space fighter]]s, and the delivery of [[UNSC Marine Corps|UNSC Marines]] into combat.

The UNSC Navy was created during the [[Interplanetary War]] of the [[2160]]'s—precisely during the [[Mars Campaign]] of [[2163]]—as a result of the [[United Nations]]' need to oversee and monitor [[UNSC Marine Corps|Marine]] deployments from space, thus forming the [[United Nations Space Command]]. After the UN's victory in that war, the UNSC Navy became involved in colonization, the settling of minor trade disputes, and anti-[[piracy]] operations as humanity spread through space.<ref name="evolutions436">'''[[Halo: Evolutions]]''', "[[The Impossible Life and the Possible Death of Preston J. Cole]]", ''pages 436-437''</ref>

Such low-level operations continued until the [[Insurrection]], which forced the Navy to develop a modern space warfare doctrine. Beginning with the [[Callisto Incident]] of [[2494]], the UNSC Navy was involved in a series of small but important actions against [[Insurrectionists]] across human space.<ref name="evolutions cole">'''Halo: Evolutions''', "The Impossible Life and the Possible Death of Preston J. Cole"</ref> In 2494, the [[Eridanus Government]] requested aid from the UNSC when rebels performed a well-planned and efficiently executed [[terrorism|terrorist]] campaign on the planet. This led to [[Operation: CHARLEMAGNE]] in [[2494|January of 2496]], when the UNSC Navy responded to the government's requests and began their campaign to retake Eridanus II, deploying a battle group to engage the makeshift Insurrectionist defense fleet.<ref>'''[[Halo Encyclopedia]]''', ''page 44'' (2011 edition)</ref> The clandestine activities of the [[Office of Naval Intelligence]] also proved to be particularly useful in dealing with Insurrectionists during [[Operation: TREBUCHET]] in the [[Eridanus system|Eridanus]] and [[Epsilon Eridani system]]s.<ref>'''[[Halo: Contact Harvest]]''', ''pages 9-20''</ref> The Navy played an important role in the elimination of rebel cells and in engagements of more organized insurgent groups—most notably the [[United Rebel Front]]. Other major battles and engagements the UNSC Navy participated in include the [[Battle of Theta Ursae Majoris]] and the [[Skirmish at Capella]].<ref name="evolutions cole"/>

 

At the [[Battle of Alpha Aurigae]] in the [[Origami Asteroid Field]] in [[2526|October 2526]], a total of 117 UNSC naval vessels defeated the Covenant's twelve—at least three of which were {{Class|CAS|assault carrier}}s. However, thirty-seven UNSC ships were lost. The [[Battle of XI Boötis A]] in 2528 saw the loss of thirty ships out of the UNSC's seventy to the Covenant.<ref name="battles">'''Halo: Evolutions''', "The Impossible Life and the Possible Death of Preston J. Cole", ''page 470''</ref> The [[Battle of the Great Bear]] at the [[Groombridge 1830 system]] in [[2530]] saw eleven destroyers out of the fleet of seventeen destroyed by three enemy ships.<ref name="battles"/>

[[File:H2A - BattleofEarth.png|250px|thumb|The Home Fleet engaging Covenant vessels during the Battle of Earth.]]

By [[2536]], the Covenant had begun to encroach on humanity's [[Inner Colonies]]. To prevent the Covenant from discovering more [[human colonies]] or Sol itself, Admiral Preston Cole established the [[Cole Protocol]]. The protocol forbade retreating vessels from setting a direct slipspace course toward any colony and dictated the destruction of navigation data on Covenant-captured naval ships. Every shipboard commanding officer in the Navy was ordered to read the new protocol.<ref>'''[[Halo: The Cole Protocol]]''', ''page 33''</ref> Some naval vessels, such as {{UNSCShip|Midsummer Night}}, were ordered to patrol UNSC space to enforce to Cole Protocol.<ref>'''Halo: The Cole Protocol''', ''page 36''</ref> In [[2543]], the UNSC Navy scored one final offensive victory against the Covenant at the [[Battle of Psi Serpentis]], though at the cost at the apparent death of Preston Cole.<ref name="evolutions cole"/> Towards the end of the Covenant War, most remaining UNSC ground forces were consolidated on worlds in the Epsilon Eridani and [[Sol system]]s. As a result, the only representative that several surviving colonies had of UEG authority and defense were UNSC Navy ships. While the Navy attempted to provide aid to colonies cut off from direct military assistance, worlds with little strategic value or unstable local governments were sometimes abandoned to prevent risking the loss of irreplaceable Navy vessels and personnel.<ref name="fb9">'''[[Halo: Fleet Battles]]''', ''Cole Rulebook - page 9''</ref>

In [[2552]], the Navy scored a morale-boosting [[Battle of Sigma Octanus IV|victory]] at [[Sigma Octanus IV]], but this was quickly offset by the crippling military losses of the [[Fall of Reach]] and the [[Battle of Tribute]]. The Navy lost over a hundred ships, including irreplaceable cruisers and supercarriers such as the {{UNSCShip|Basra}}, {{UNSCShip|Trafalgar}}, and the {{UNSCShip|Musashi}} at [[Reach]],<ref>'''[[Halo: The Fall of Reach]]''', ''page 320'' (2001 edition)</ref><ref>'''[[Halo: First Strike]]''', ''page 168'' (2003 edition); ''page 206'' (2010 edition)</ref> and lost ninety percent of naval assets at [[Tribute]].<ref>'''[[Halo 3: ODST]]''', ''Dutch's biography''</ref> In the same year, a very large portion of its remaining ships were lost when the [[Prophet of Truth]]'s [[Truth's fleet|military forces]] occupied [[Earth]]. As a result, the UNSC Navy was only able to make a contribution of three [[UNSC frigate|frigates]] to the [[Battle of Earth]] and the [[Battle of Installation 00]], with the [[Swords of Sanghelios|Sangheili]] navy handling most of the space fighting.<ref>'''[[Halo 3]]''', campaign levels ''[[The Storm]]'', ''[[Floodgate]]'', and ''[[The Ark (level)|The Ark]]''</ref>

In the aftermath of the Human-Covenant War, all remaining naval assets were gathered to the [[Sol system]] for months so that the UNSC could take stock of its fleet. This time was spent accounting for, repairing, and refitting what little remained—only a few hundred vessels.<ref>'''[[Halo Mythos]]''', ''page 132''</ref> The Office of Naval Intelligence began operations to sow dissent amongst the [[Sangheili]], disregarding their wartime alliance in the hopes of rendering them unable to fight should they become a threat again. Among this operation's effects was the beginning of the [[Blooding Years]] and the establishment of a [[Jul 'Mdama's Covenant faction|Covenant remnant]] led by [[Jul 'Mdama]].<ref>'''Halo: Glasslands''', ''page 22''</ref> While the former Covenant fleet's naval vessels fell into the hands of various splinter factions established by the former client species,<ref>'''[[Halo 4: The Essential Visual Guide]]''', ''page 195''</ref><ref>'''[[Eleventh Hour reports]]''', ''Report 2''</ref> the UNSC Navy began to rebuild and continued to grow.<ref>'''Halo: Glasslands''', ''page 43''</ref> In the aftermath of the war, the rapidly modernizing Navy introduced the {{Class|Autumn|heavy cruiser}}, based on the highly resilient advancements applied to the {{UNSCShip|Pillar of Autumn}} as well as the {{Class|Strident|heavy frigate}} and the {{Class|Anlace|frigate}} among others, rapidly supplanting the prewar designs still central to the UNSC Navy.   

In early [[2553]], the Navy launched its most powerful warship, the {{UNSCShip|Infinity}}, though she would not be officially commissioned for another four years. Built in secret using technology recovered from [[Forerunner]] and [[Covenant]] sources during the war, the ''Infinity'' is the UNSC's largest and most advanced warship to date.<ref name="Glasslands 422">'''Halo: Glasslands''', ''pages 421-422''</ref> In March 2553, she secretly intervened in the [[Blooding Years|Sangheili civil war]], and demonstrated the UNSC's new technical capabilities by easily destroying the [[Covenant destroyer]] ''[[Defender of Faith]]''.<ref>'''[[Halo: The Thursday War]]''', ''page 303''</ref> A second such ship of the ''Infinity''-class, the ''{{UNSCShip|Eternity}}'', was still in development as of 2558.<ref>'''[[Halo: Warfleet]]''', ''page 42''</ref>

In [[2557#July|July 2557]], the ''Infinity'' distinguished herself during the [[Battle of Requiem]] and the recovery of Master Chief Petty Officer [[John-117]]. The UNSC Navy's forces around Earth had also been rebuilt, and the [[UNSC Home Fleet|Home Fleet]] [[New Phoenix Incident|defended the planet]] against the [[Didact]] when he arrived with the intention of digitizing all of humanity with the Forerunner weapon known as the [[Composer]]. Earth's orbital platforms and the Home Fleet's [[Battlegroup Dakota]] had little to no effect against the Didact's ship, the ''[[Mantle's Approach]],'' but the ''Infinity'' managed to damage the ship, allowing John-117 to enter using an [[F-41 Broadsword]] and destroy the ship with a [[HAVOK tactical nuclear weapon]]. The fighting continued six months later with the ''Infinity'''s [[Requiem Campaign|second expedition on Requiem]].<ref>'''[[Halo 4]]''', campaign level ''[[Midnight]]''</ref>

On [[2558#October|October 28, 2558]] the UNSC Navy was largely [[Subjugation of Earth|incapacitated]] by [[Cortana]]'s [[Guardian]]s, with only a few ships, including ''Infinity'', managing to escape the [[Created]].<ref name="Guardians">'''[[Halo 5: Guardians]]''', campaign level ''[[Guardians (level)|Guardians]]''</ref><ref name="Rossbach">'''[[Halo: Fractures]]''', ''[[Rossbach's World (story)|Rossbach's World]]''</ref>

The UNSC Navy is subordinate to the [[UNSC High Command]] (HIGHCOM). The Navy is administered by the [[UNSC Naval Command]], or NAVCOM, headed by the [[Chief of Naval Operations]], which in [[2558]] was [[Terrence Hood|Fleet Admiral Lord Hood]]. The CNO is assisted by the [[Deputy Chief of Naval Operations]].<ref name="fs">'''Halo: First Strike''', ''page 22''</ref> NAVCOM is split into three commands; [[Fleet Command]], or FLEETCOM, has oversight of ship deployment, mission structures, and space operations, including the transport of troops and naval fighter operations. [[Logistical Operations Command]], or NavLogCom, oversees the construction, maintenance, and distribution of supplies and matériel, including ships, ammunition, replacement parts, and food. [[UNSC Special Forces|Naval Special Warfare Command]], or NAVSPECWARCOM, and Naval Special Weapons (NAVSPECWEP) are responsible for all Naval special operations, including deployments of [[SPARTAN-II program|SPARTAN-II]]s.<ref name="enc">'''Halo Encyclopedia''', ''page 64'' (2011 edition)</ref> The UNSC Navy also operates [[Central Command]]s (CENTCOM) which hold responsibility over a certain area of space. A CENTCOM commander has the authority to blockade a system,<ref name="evolutions436"/> or aid in the coordination of a battle occurring within the regional space they command.<ref>'''[[Halo: Reach]]''', ''[[Halo: Reach radio conversations#Part 6 - Reflection|Reflection radio conversation]]''</ref> UNSC and UEG space is further divided, governed, and protected by the Navy's [[UNSC Fleet Command#FLEETCOM Sectors|Fleet Command sectors]] which each contain a number of planetary systems.<ref>'''Halo: The Fall of Reach''', ''page 289''</ref>

The [[Office of Naval Intelligence]] is technically subordinate to the UNSC 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.<ref name="enc"/> ONI holds a strong presence in the UNSC fleet and maintains joint control of the Navy's post-war flagship, {{UNSCShip|Infinity}}.<ref>'''Halo: The Thursday War''', ''page 46''</ref> Despite being under the command of the Navy, ONI's [[Commander-in-Chief of the Office of Naval Intelligence|Commander-in-Chief]] holds a seat on the [[UNSC Security Council|Security Council]] with equal stature and privilege to the committee members of the Navy, Marines, Army, and Air Force.<ref name="HE1">'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 1|Issue #1]]''</ref>

Commanding positions in NAVCOM tend to be held by [[admiral]]s.<ref name="fs"/><ref name="h2">'''[[Halo 2]]'''</ref><ref name="goo"/> Because of their role as an "amphibious", space-deployed force, the [[UNSC Marine Corps]] enjoys a close relationship with the Navy, with Marine complements being deployed on most [[warship]]s.<ref name="h2"/><ref>'''[[Halo: Combat Evolved]]'''</ref><ref name="tfor">'''Halo: The Fall of Reach'''</ref>

UNSC Navy forces are divided into a number of [[UNSC fleet|fleets]]. These tend to be large formations, though they seldom patrol together; single ships are commonly seen patrolling throughout UNSC space.<ref name="tfor"/> System defense fleets, such as the [[UNSC Home Fleet]] or the [[Epsilon Eridani Fleet]], are commonly formed to patrol and defend a human colonized-system.<ref name="fb9"/><ref name="Crows">'''Halo 2''', campaign level ''[[Cairo Station (level)|Cairo Station]]''</ref> Defense fleets were often considered to be little more than glorified revenue police, though they proved to hold an imperative role during the [[Human-Covenant War]] as they provided desperately needed training cadres and battle-ready—albeit, sometimes outdated—warships.<ref name="fb9"/> The UNSC Navy also has several numbered expeditionary fleets,<ref name="fb9"/> five of which were active during the Covenant War—the [[Second Fleet|Second]], [[Third Fleet|Third]], [[Fifth Fleet|Fifth]], [[Seventh Fleet|Seventh]], and [[Sixteenth Fleet]]s.<ref>'''Halo: Ghosts of Onyx''', ''page 205''</ref> Several expeditionary fleets were decimated early in the Covenant War. By late [[2552]], there was no longer any appreciable difference between fleets, as the Navy was no longer capable of conducting offensive operations without leaving the remaining colonies and Earth vulnerable.<ref name="fb9"/>

 

These fleets are further divided into several [[battle group]]s,<ref>'''[[Halo: The Essential Visual Guide]]''', ''page 188''</ref> more common [[UNSC Navy tactical formations|tactical formations]] which are formed on an as-needed basis and vary dramatically in size from three ships to large carrier groups.<ref name="evolutions cole"/><ref name="goo">'''[[Halo: Ghosts of Onyx]]'''</ref><ref>'''[[Halo Wars: Genesis]]'''</ref><ref>'''[[Halo Graphic Novel]]''', ''page 86''</ref> Battle groups are flexible fighting organizations that can be "plugged together" into arranged [[task force]]s. A squadron is a group of warships that is smaller than a fleet. By the final years of the Covenant War, squadrons became administrative—rather than tactical—units that ships were enrolled in for record-keeping and honorific purposes. [[Artificial intelligence]] administrators of the Navy carefully arranging the dwindling ship roles into attack, battle, carrier, monitor, and support squadrons. Many of the Navy's fleets had also become "paper fleets", or "dead fleets", with no command and no ships. These fleets were assigned to [[sector]]s lost to the Covenant early in the war, with their destroyed squadrons remaining attached to the sector to honor their sacrifice and as deference for tradition. A new ship was occasionally inadvertently attached to one of these dead fleets due to bureaucratic error.<ref name="fb9"/>

[[File:UNSCAircraftCarrier.png|thumb|250px|An aircraft carrier near the Mombasa Quays.]]

Into the 26th century, the UNSC Navy continued to use maritime ships to patrol the seas. Little is known about this Naval arm. It is known, however, that Earth and the fortress world of [[Reach]] had bases for it. Other than that, it is known that the Navy possessed numerous [[UNSC aircraft carrier|aircraft carriers]] with full complements of [[F-99 Wombat|F-99 Unmanned Combat Aerial Vehicle]]s,<ref>'''Halo 3''', multiplayer level ''[[Longshore]]''</ref> suggesting that they were constantly kept at a high level of alert.

Other than participating to some extent during the [[Battle of Mombasa]], the wet Navy may have been involved with the operation to the [[Yucatan Peninsula]], where the [[SPARTAN-II program|SPARTAN]] [[Blue Team]] attacked and destroyed a Covenant excavation force on the sea floor of the [[Wikipedia:Gulf of Mexico|Gulf of Mexico]].<ref name="goo204">'''Halo: Ghosts of Onyx''', ''pages 203-204''</ref>

Large numbers of men and women are employed by the UNSC Navy. Servicepeople hold ranks, which are divided between officers and enlisted. UNSC Navy personnel are given training in self-defense. All crewmen are trained to use the [[M6 series|M6 series of handguns]].<ref>'''Halo: Combat Evolved''', campaign level ''[[The Pillar of Autumn (Halo: Combat Evolved level)|The Pillar of Autumn]]''</ref> Naval personnel are sometimes referred to as "[[swabbie]]s", which can be a joke or a sign of disrespect.<ref name="flood"/><ref>'''Halo: First Strike''', ''page 92''</ref> 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.<ref>'''Halo: Evolutions''', "The Impossible Life and the Possible Death of Preston J. Cole", ''page 421''</ref> Several [[human colonies]] are home to [[Officer Candidate School]]s that provide training and allows enlisted personnel or civilians to become officers.<ref name="for38">'''Halo: The Fall of Reach''', ''page 38''</ref> Renowned OCS academies include the [[Academy at Mare Nubium|Luna OCS Academy]] and the [[Corbulo Academy of Military Science]].<ref>'''[[Halo 4: Forward Unto Dawn]]''', ''Part 1''</ref>

UNSC Navy personnel wear distinctive [[UNSC Navy uniforms|uniforms]] for identification, comfort, and practicality. [[UNSC Navy Dress Uniform|Dress uniforms]] are worn on formal occasions, such as ceremonies and other official functions,<ref name="h2"/> while [[UNSC Navy Service Uniform|service]] and [[UNSC Navy Working Uniform|working uniform]]s are the basic uniform worn by UNSC Naval personnel while on duty.<ref>'''Halo: Contact Harvest''', ''page 322''</ref><ref>'''Halo 2''', campaign level ''[[Delta Halo (level)|Delta Halo]]''</ref> Carrier flight crew are a mix of Navy and Marine personnel, divided into "Blue" and "Green" sides respectively, with coloured jerseys signifying their role on the flight deck: red for ordnance handlers, white for safety technicians, green for technicians, and so on.<ref>'''Halo: Warfleet''', p 41</ref>

==Equipment==

UNSC Navy vessels are typically armored with [[Titanium-A armor]]; such protective armor remained the defensive standard of UNSC vessels<ref>'''Halo: Ghosts of Onyx''', ''page 185''</ref> until they were further reinforced with the introduction of [[energy shielding]] in the post-war era. At least the Navy's flagship, {{UNSCShip|Infinity}}, and {{Class|Strident|heavy frigate}}s are equipped with energy shields,<ref>'''[[:File:H4FrigateShields.jpeg|Image showing frigate shields above hull]]'''</ref> while {{class|Autumn|heavy cruiser}}s featured a cheaper but more limited system of localised shield emitters.<ref>'''[[Halo: Warfleet]]'''</ref>

The primary offensive armament of UNSC spacecraft is the [[Magnetic Accelerator Cannon]] (MAC). These are high velocity coil guns that are used to accelerate projectiles ranging in mass from 600 metric tons in the case of smaller warships, and 3,000 tons in the case of Super MAC platforms. These projectiles are composed of [[titanium]], [[depleted uranium]], or [[tungsten]] with a [[Iron (element)|ferrous]] core. "Super MAC" [[Orbital Defense Platform]]s accelerate MAC rounds to "point four-tenths" the speed of light<ref>'''Halo: The Fall of Reach''', ''page 297'' (2001 edition); ''page 320'' (2010 edition)</ref> with twenty-three linear accelerator coils, while ship-based MACs have a lower velocity. Super MAC platforms can also reload a round in five seconds, where as ships will need several minutes to charge their MAC coils.<ref name="for108">'''Halo: The Fall of Reach''', ''page 108'' (2001 edition); ''page 130'' (2010 edition)</ref>

The UNSC frigate ''[[UNSC Gettysburg|Gettysburg]]'' is quoted as firing a 600 ton shell at 30 kilometers per second.<ref name="for108"/> Before Reach fell, the {{UNSCShip|Pillar of Autumn}} was equipped with a modified MAC that could quickly fire three lighter projectiles in succession instead of just one heavier projectile. It was originally intended to allow the ''Pillar of Autumn'' a better chance of disabling a Covenant ship, which was a feature required for a mission that was later scrubbed following the [[Fall of Reach]].

Ships of the UNSC Navy also carry a number of [[GA-TL1 Longsword|GA-TL1 Longsword interceptors]]. These are armed with [[110mm rotary cannon]]s and [[ASGM-10 missile]]s, and sometimes a [[Moray space mine]] system or even a single Shiva-class nuclear missile. They can also be remotely-operated and used to carry a remotely-detonated Shiva missile, which, when detonated, effectively destroys both the Longsword and its selected target.<ref name="evg112">'''Halo: The Essential Visual Guide''', ''page 112''</ref>

Despite all of this firepower, however, UNSC warships during the Human-Covenant War had great difficulty in defeating Covenant ships even with a numerical advantage. It typically took multiple hits from a ship-based MAC weapon to disable a Covenant ship's shields, although larger, [[Orbital Defense Platform|ODP-based]] "Super MACs" fire a round that can literally shatter Covenant capital ships.<ref>'''Halo: The Fall of Reach''', ''page 297''</ref> Archer missiles had to be used in tremendous volumes to breach Covenant shield systems. Even with their shields down, Covenant ships have been noted to remain operational after multiple direct hits from normal MAC rounds. Throughout the [[Human-Covenant War]], this advantage in firepower and shielding gave the Covenant an effective 3:1 ratio when in battle against the UNSC. However, as of the [[Timeline|post-war era]], thanks to Forerunner technology and the [[Huragok]] retrieved from [[Onyx]], UNSC ships have become faster and stronger, making them more effective against Covenant vessels.

[[File:H2A - In Amber Clad render 3.jpg|thumb|left|300px|The UNSC frigate, the most common of UNSC Navy ships.]]

The largest vessels of the UNSC fleet are [[UNSC carrier|carrier]]s and [[UNSC supercarrier|supercarriers]].<ref name="tfor"/> While possessing weapons of their own, their primary role is to deploy fighter craft such as the [[GA-TL1 Longsword]], and may serve as [[flagship]]s in fleet actions.<ref name="goo"/> If a carrier is unavailable, however, then heavily-armed and armored [[cruiser]]s may fill this role.<ref name="tfor"/> The UNSC Navy has fielded numerous carrier types, among them the {{Class|Epoch|heavy carrier}}, the {{Class|Orion|carrier}}, and the postwar {{Class|Poseidon|light carrier}}. The [[Punic-class supercarrier]]s, among the largest vessels in human history, upheld the Navy's outreach and field capabilities as "Space Control Vehicles" before assuming offensive roles in the Human-Covenant War. The ''Punic''-class was one of the few vessels to rival those of the Covenant in terms of tonnage and firepower. The current flagship of the UNSC Navy is the {{UNSCShip|Infinity}}, the first of the [[Infinity-class supercarrier|''Infinity''-class supercarriers]] which make use of defensive and offensive advances reverse-engineered from both Forerunner and Covenant technologies, with the specific intention of matching Covenant warships in terms of offensive firepower.<ref name="Glasslands 422"/> The UNSC Navy has operated four known classes of cruiser; the {{Class|Marathon|heavy cruiser}}, the {{Class|Valiant|super-heavy cruiser}}, the now-obsolete {{Class|Halcyon|light cruiser}}, and the postwar {{Class|Autumn|heavy cruiser}}.<ref>'''Halo 4: The Essential Visual Guide''', ''page 191''</ref>

Th primary shipyards utilized by the UNSC Navy are on and in orbit of [[Mars]],<ref name="havesmoa">[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-have-s-moa '''Halo Waypoint''': ''Canon Fodder - Have S'moa'']</ref> with at least some UNSC ship production handled by the [[Reyes-McLees Shipyards]] over Mars.<ref>'''Halo: The Fall of Reach''', ''page 238''</ref> [[Tribute]] is also host to prominent shipbuilding yards. By the end of the Covenant War, the shipyards orbiting Tribute and Mars began building a new generation of warships for the UNSC.<ref>[https://www.halowaypoint.com/en-us/news/canon-fodder-buzz-generating '''Halo Waypoint''': ''Canon Fodder - Buzz Generating'']</ref> Additionally, [[SinoViet Heavy Machinery]] manufactured and decommissioned {{Class|Paris|heavy frigate}}s on [[Reach]] prior to the [[Fall of Reach]].<ref name="alexandria">'''Halo: Reach''', campaign level, ''[[New Alexandria (level)|New Alexandria]]''</ref>

[[Space fighter]]s are small, maneuverable spacecraft, often used for bombing or "dog fighting" in space or in an atmosphere. The UNSC Navy operates a number of fighters, the most common of which is the [[GA-TL1 Longsword]]. The Longsword is a multi-role fighter that can be used in a variety of missions, including ground support, anti-ship attacks, and combat with other fighters.<ref name="tfor"/><ref name="evg112"/>

The [[F-41 Broadsword]] is a multirole space fighter in use after the Human-Covenant War. Like the Sabre, the Broadsword is equipped with energy shielding that covers the entire fighter and recharges when depleted. However, these shields are not rated for slipspace travel. The Broadsword is equipped with two [[Machine-linked autocannon#M1075 ASW/AC 35mm|M1075 ASW/AC 35mm MLA cannon]]s and two [[ST/Medusa missile#M6088 ST/MMP|M6088 ST/MMP missile]] pods. The fighter can also be equipped with a single piece of heavy ordnance, such as a [[HAVOK tactical nuclear weapon|HAVOK warhead]].<ref name="H4VG114">'''Halo 4: The Essential Visual Guide''', ''page 114''</ref>

A less common UNSC fighter is the [[OF92 Booster Frame|OF92/EVA "Booster Frame"]]. The Booster Frame is an experimental fighter developed as a prototype. They are specifically designed for [[extra-vehicular activity]] and special operations roles, dropped from hooks within the hangars of specialized UNSC ships. The fighter itself has no sealed cockpit, so a [[Vacuum suit|pressurized suit]] must be worn in order to operate the vehicle.<ref>'''Halo Waypoint''', ''Gauss Technology article''</ref><ref>'''Halo Waypoint''', ''Booster Frame article''</ref>
