{{Quote|What the hell are those things?|Cadet Thomas Lasky, upon seeing ''SDV''-class heavy corvettes for the first time<ref name="fud">'''[[Halo 4: Forward Unto Dawn]]''', ''Part 3''</ref>}}

The '''''SDV''-class heavy corvette''' is a class of [[corvette]], formerly in service with the [[Covenant]] [[Covenant fleet|fleet]].<ref name="ONI: SB">'''[[Halo: Reach]]''', campaign level, ''[[ONI: Sword Base]]''</ref><ref name="LNoS">'''Halo: Reach''', campaign level, ''[[Long Night of Solace (level)|Long Night of Solace]]''</ref> Manufactured by both the [[Forgemasters of Tanus]] and the [[Gorgon Assembly Vault]],{{Ref/Reuse|Warfleet}} these corvettes rarely engage in ship-to-ship combat (though if pressed, they are capable of taking on [[human]] [[frigate]]s on more-or-less even terms); instead, they typically escort [[capital ship]]s, deploy [[space fighter]]s in [[fleet]] engagements, and screen support ships from enemy fast-attack craft.{{Ref/Reuse|universe}} Although they typically serve as heavy escorts within a fleet, the ''SDV'' class can operate independently of support for extended periods of time.<ref name="mythos">'''[[Halo Mythos]]''', ''p. 154-155''</ref>

Mass-assembled during the [[Ages of Discovery|Twentieth Age of Discovery]], ''SDV''-class heavy corvettes were originally commissioned for charting distant stars and dangerous [[slipspace]] routes, or aiding the Covenant navy in war.{{Ref/Reuse|Warfleet}} During the [[Human-Covenant War]], the ''SDV'' class saw heavy use against humanity, most prominently during the [[Fall of Reach]].{{Ref/Reuse|essential}} With the collapse of the Covenant Empire, these corvettes are now serviced by the Covenant's [[Covenant remnants|successors]].{{Ref/Reuse|Have S'moa}}

==Specifications==
===Superstructure and hull===
{{Quote|Scans indicate a structural weakness surrounding a platform on top of the vessel.|Auntie Dot, referring to the ''SDV'' class{{Ref/Reuse|LNoS}}}}
[[File:HWF-ArdentPrayer.jpg|thumb|250px|left|A cutaway illustration of the ''Ardent Prayer'']]
''SDV''-class heavy corvettes are relatively small [[warship]]s once manufactured by the [[Covenant]],{{Ref/Reuse|universe}} with a length of 956 meters and a mass of 8 million metric tons.{{Ref/Reuse|Warfleet}} Like all Covenant vessels, these corvettes are armored with a lightweight, yet incredibly resilient, diamondoid and metal-matrix composite frame, covered by thin pieces of streamlined [[nanolaminate]] hull plating.{{Ref/Reuse|wf61}} Identifiable by their smooth oblong shape, the ''SDV''-class heavy corvettes are assembled with a selvage rim, a contoured extension of the hull for additional protection that is also capable of deploying combat carapaces. The rim is visually reminiscent of [[Suban]]'s [[qoerith slug]]s.{{Ref/Reuse|mythos}} ''SDV'' corvettes have a dorsal landing platform at the top of the ship,{{Ref/Reuse|essential}} a noted structural weakness to the design of the corvette. Red and blue lights are used to distinguish the port and starboard sides of the ship.{{Ref/Reuse|LNoS}} Mass-assembled in large numbers by the Covenant, the ''SDV''-class heavy corvette has a highly flexible [[design pattern]] that can be modified for a number of specialized roles.<ref name="fb121">'''[[Halo: Fleet Battles]]''', ''Core Rulebook'', ''p. 125''</ref>

The cavernous war [[bridge]] of the ''SDV'' corvette is located in the bow of the ship, rather than the center.{{Ref/Reuse|LNoS}} Referred to as the command center,<ref name="evg13">'''Halo: The Essential Visual Guide''', ''p. 13''</ref> the bridge is comparatively large and composed of an encompassing perimeter platform that surrounds a number of control consoles, with a [[holo-tank]] in the center and a retractable conference table off to the side.{{Ref/Reuse|hitd134}} In addition to the bridge's high-tier [[auspex array]] and [[battlenet]] interlinks,{{Ref/Reuse|mythos}} the ''SDV'' class is also equipped with a long-range communication system near the center of the ship for synchronizing orders and edicts.{{Ref/Reuse|Warfleet}} Located at the corvette's midsection is the ministerial cloister, an elevated access point and common terrace for dignitaries and commanders.{{Ref/Reuse|mythos}} ''SDV'' corvettes have a highly advanced [[automated surgery suite]] typically capable of tending to most injuries. As most [[Sangheili]] prefer to avoid the medical bay, the suite is frequented more by other species.<ref>'''Halo: Hunters in the Dark''', ''p. 308''</ref> The SDV initially had a series of maintenance tunnels interwoven throughout the ship, with compact dimensions designed for the Covenant's smaller species to traverse.<ref name="Covenant Escape">'''[[Halo: Outpost Discovery]]''', ''[[Covenant Escape]]''</ref>

[[File:HOD SupplicationofPurity Interior 1.jpg|left|thumb|200px|The interior of a maintenance corridor of the ''Supplication of Purity''.]]
The ''SDV'' class is outfitted with [[Energy shielding|''Morelia''-pattern dispersal field generators]],{{Ref/Reuse|Warfleet}} which provide the corvettes with energy shielding.<ref name="Halo p. 145">'''Halo: Hunters in the Dark''', ''p. 145''</ref> The corvettes are also equipped with a [[Active camouflage|''Ushab''-pattern stealth generator]], utilizing powerful distortion screens and a multispectral hypersink that renders the ships practically invisible to long-range passive sensors.{{Ref/Reuse|Warfleet}} A [[gravity lift]] near the center serves as a low-capacity utility lift for cargo transport.{{Ref/Reuse|mythos}}

===Propulsion===
''SDV''-class corvettes are highly regarded for their maneuverability and swiftness, using a combination of speed and stealth to infiltrate planetary defenses, though they are not as nimble as the {{Class|DAV|light corvette}}s.{{Ref/Reuse|essential}} The corvettes are fitted with four [[Repulsor engine|''Callipoas''-pattern repulsor engines]],{{Ref/Reuse|Warfleet}} located at the aft of the ship.{{Ref/Reuse|LNoS}}<ref name="Exodus">'''Halo: Reach''', campaign level, ''[[Exodus]]''</ref><ref name="Nightfall">'''Halo: Reach''', campaign level, ''[[Nightfall]]''</ref> Providing sublight travel, these repulsor engines are configured for swift and agile localized transit.{{Ref/Reuse|mythos}}

For travel in [[slipstream space]], the ''SDV'' class is outfitted with a [[Slipspace drive|''Tyros''-pattern borer]]—approximately equivalent to a [[Shaw-Fujikawa Translight Engine#CODEN series|CODEN Series VI Shaw-Fujikawa Translight Engine]].{{Ref/Reuse|Warfleet}}

===Crew and complement===
[[File:Corvette1.jpg|thumb|250px|The hangar of the ''SDV''-class heavy corvette]]
''SDV'' corvettes generally have a crew of thirty-eight,{{Ref/Reuse|Warfleet}} though these vessels are highly automated and only require a crew of ten for most operations.<ref>'''Halo: Hunters in the Dark''', ''p. 135''</ref> The crew consists of sixteen [[Sangheili|Superior]]s, twenty [[Menial]]s, and two [[Huragok]] serving as the ship's engineers.{{Ref/Reuse|Warfleet}} ''SDV''-class heavy corvettes are favored for their infantry transport and deployment capabilities.{{Ref/Reuse|essential}} They can carry fifty [[Sangheili Major|Sangheili Obedientaries]], another fifty [[Warrior]]s, and one hundred-and-thirty [[Thrall]]s. There are no long-term accommodations for the crew, except for those of the [[shipmaster]]. Instead, the crew use stimulants and [[dream-shaper]]s to stay alert for their tour, before being rotated with fresh personnel at the end of the mission.{{Ref/Reuse|Warfleet}}

Corvettes of this class have a single multipurpose [[hangar bay]],{{Ref/Reuse|hitd134}}{{Ref/Reuse|mythos}}<ref name="fb">'''Halo: Fleet Battles'''</ref> rated to handle heavy [[dropship]]s and medium [[space fighter]]s.{{Ref/Reuse|mythos}} These corvettes carry eight [[Type-31 Seraph]] fighters,{{Ref/Reuse|Warfleet}} locked onto the ceiling of its hangar bay.{{Ref/Reuse|evg13}} Seraph [[pilot]]s may be trained by a [[skymaster]]. In addition, ''SDV''-class corvettes carry ten [[Type-27 Banshee]] strikecraft and eight [[Type-26 Banshee]] support aircraft. Two [[Type-25 Spirit]] troop carriers are utilized by these corvettes to ferry troops to combat zones. ''SDV'' corvettes carry 104 [[Covenant drop pod|insertion pods and deployment carapaces]],{{Ref/Reuse|Warfleet}} deployed from the lower ring.{{Ref/Reuse|mythos}} When launched, the drop pods benefit from a temporary signature reduction when passing through the ship's distortion screen.{{Ref/Reuse|Warfleet}}

===Armaments===
Armed with relatively light weaponry, ''SDV'' corvettes rarely engage in ship-to-ship combat, often deploying fighters to engage enemies while the corvette escapes.{{Ref/Reuse|essential}} However, they are capable of engaging [[human]] [[frigate]]s on more-or-less even terms, if pressed.{{Ref/Reuse|universe}} The primary armament of the corvette is its array of six [[Plasma cannon (starship)|''Melusean''-pattern heavy plasma cannons]],{{Ref/Reuse|Warfleet}}{{Ref/Reuse|mythos}} with three on either side of the ship.{{Ref/Reuse|Warfleet}} The plasma cannon array is capable of rapid fire, providing dynamic-range flank coverage.{{Ref/Reuse|mythos}} The ''SDV'' class is also armed with sixteen [[Plasma bombardment mortar|''Carnax Nu''-pattern plasma bombardment mortars]] designed for bombarding surface targets. For point defense, the corvettes possess eleven [[Pulse laser turret|''Phot''-pattern pulse lasers]].{{Ref/Reuse|Warfleet}} Some corvettes are armed with low-yield [[antimatter mine]]s.{{Ref/Reuse|Halo p. 145}}

The "S" (for "Salvation") in the corvette's three-letter classification code indicates that the ''SDV''-class heavy corvette is a dedicated warship capable of cleansing enemies of the Covenant with "holy fire".{{Ref/Reuse|Have S'moa}}

==Operational history==
===Early service===
The ''SDV''-class heavy corvette was mass-assembled in large numbers by the [[Forgemasters of Tanus]] and the [[Gorgon Assembly Vault]] during the [[Ages of Discovery|Twentieth Age of Discovery]], an earlier era of glorious exploration for the [[Covenant]]. The corvette was designed by [[Master Shipwright]] [[Ckmu 'Raboree]] and [[Apprentice Hiveseeker]] [[Tek'ch]]—[[Sangheili]] and [[Yanme'e]] naval architects, respectively. ''[[Ardent Prayer]]'' was one of the corvettes assembled at this time, commissioned in around [[2070]].{{Ref/Reuse|Warfleet}}

The Covenant tasked the new ''SDV''-class with traveling to distant stars, charting dangerous routes in [[slipstream space]], and battling civilizations that resisted the empire's vision of a [[Great Journey]].{{Ref/Reuse|Warfleet}} Others were tasked with surveying [[Forerunner]] reliquary sites and deploying small artifact-retrieval teams to evade any active defensive measures.{{Ref/Reuse|universe}} However, such matters were often considered beneath the attention of true warriors; while these corvettes played vital roles in the [[Covenant fleet]], they possess no battle honors of note and are rarely mentioned in [[High Charity]]'s records.{{Ref/Reuse|Warfleet}} Nonetheless, the ''SDV'' was a popular warship in the fleet, with entire [[battle group]]s comprised of these corvettes.{{Ref/Reuse|fb121}}

===Human-Covenant War===
[[File:CirciniusIV attacked1.jpg|left|250px|thumb|A corvette fires a pulse laser at the Corbulo Academy space elevator, destroying it.]]
During the [[Human-Covenant War]], ''SDV'' heavy corvettes were utilized in front-line combat roles, as well as providing the Covenant fleet with long-range reconnaissance of potential naval staging areas and colonies.{{Ref/Reuse|universe}} At least three ''SDV''-class heavy corvettes were present during the Covenant's [[Battle of Circinius IV|attack]] on the [[human]] [[Human colonies|colony]] of [[Circinius IV]] in [[2526]]. During the battle, the three corvettes entered the planet's lower atmosphere over the [[Corbulo Academy of Military Science]], where one of them fired on the school's [[space elevator]], causing it to collapse.{{Ref/Reuse|fud}} A lone corvette was present for the beginning of the [[Battle of Meridian]] in [[2548]], acting as the ship for a Covenant force working on excavating a Forerunner artifact in [[Brume-sur-Mer]]. The corvette attempted to shoot down [[Sundered Legion Prowler|a]] [[Prowler]] carrying escaping colonists, firing blind due to the ship being in stealth mode. However, [[Victor Gallardo]] returned fire with the Prowler's missiles, scoring several hits and forcing the corvette to retreat.<ref name="HBB4">'''[[Halo: Battle Born]]''', ''Chapter 4''</ref><ref name="HBB16">'''[[Halo: Battle Born]]''', ''Chapter 16''</ref><ref name="HBB24">'''[[Halo: Battle Born]]''', ''Chapter 24''</ref> Several ''SDV'' corvettes participated in the [[Battle of Sigma Octanus IV]] in [[2552]], attached to the [[Second Fleet of Solemn Accord]].<ref>'''Halo Mythos''', ''p. 81''</ref>

When the [[Fleet of Valiant Prudence]] arrived over [[Reach]] later that summer, several attached ''SDV''-class heavy corvettes were present for the ensuring [[Fall of Reach]]. On [[2552#July|July 26, 2552]], a corvette [[Battle of Sword Base|attacked]] the [[Office of Naval Intelligence]]'s [[Sword Base]], but retreated when its forces were driven off. As it left, the corvette was struck amidships by a round from an [[orbital defense platform]]'s [[Magnetic Accelerator Cannon|MAC]] and sank in a nearby lake.{{Ref/Reuse|ONI: SB}} At least four corvettes were present in the Covenant staging area in the [[Viery Territory]] and were discovered by [[Recon Team Bravo]] during [[Mission to Szurdok Ridge|a reconnaissance mission]].{{Ref/Reuse|Nightfall}} Later in the battle, ''Ardent Prayer'' played a vital role in [[Operation: UPPER CUT]], when she was engaged by {{UNSCShip|Savannah}} while being [[Boarding|boarded]] by several [[YSS-1000 Sabre]] fighters, including one piloted by [[SPARTAN-B312]] and [[Jorge-052]]. The pilots hijacked the corvette and brought aboard ''Savannah''<nowiki>'</nowiki>s [[Shaw-Fujikawa Translight Engine|slipspace drive]], which was used as a [[Shaw-Fujikawa Translight Engine#Atypical uses|makeshift bomb]]. ''Ardent Prayer'' was sent towards the fleet [[flagship]] ''[[Long Night of Solace]]'', where Jorge-052 activated the drive and created a devasting [[Slipstream space|slipspace]] rift. The resulting loss of ''Ardent Prayer'' and ''Long Night of Solace'' effectively crippled the Fleet of Valiant Prudence, though the fleet's remnants were reinforced by the [[Ministry of Resolution]].{{Ref/Reuse|LNoS}}

Other ''SDV''-class heavy corvettes took part in later ground battles on Reach. At least three corvettes were present during the [[Siege of New Alexandria|siege of]] [[New Alexandria (location)|New Alexandria]]. One took up position over the city's starport, preventing civilian [[Unidentified civilian transport craft|evacuation transports]] from escaping. When one took off in desperation, the corvette shot it down. As the situation grew dire for the transports, SPARTAN-B312 reactivated a [[M95 Lance|missile battery]] which he used to fire on the corvette. The corvette was badly damaged and retreated, allowing the remaining civilian transports with thousands of people on board to escape. The corvette was last seen descending at a steep angle, indicating it may have crashed from the damage it sustained.{{Ref/Reuse|Exodus}} Several of these corvettes also participated in the Covenant's [[Battle of Tribute|attack]] on [[Tribute]], with some assaulting its capital, [[Casbah]].<ref name="landf">'''[[Halo 4]]''', multiplayer map, ''[[Landfall (level)|Landfall]]''</ref>

===Post-Covenant usage===
Following the [[Battle of the Citadel|collapse]] of the Covenant, ''SDV''-class heavy corvettes continued their service with newly formed [[Covenant remnants|successor factions]] of the fallen empire. [[Jul 'Mdama]]'s [[Jul 'Mdama's Covenant|Covenant]] had several ''SDV''-class heavy corvettes in its fleet.{{Ref/Reuse|Have S'moa}} The [[Swords of Sanghelios]] also operated at least one corvette of the ''SDV'' class—''[[Mayhem]]''. This corvette was deployed on [[Operation: FAR STORM]], delivering the joint forces of the Swords and [[United Nations Space Command]] to [[Installation 00]] via the [[Portal at Voi]].{{Ref/Reuse|hitd134}}

In [[2558#March|March 2558]], [[Shipmaster]] [[Vata 'Gajat]] was using an ''SDV''-class heavy corvette as the [[flagship]] of his [[Vata 'Gajat's mercenary group|mercenary faction]], although both corvette and shipmaster were destroyed during the [[Ambush at Oth Lodon|Oth Lodon incident]].<ref>'''[[Halo: Escalation]]''', ''[[Halo: Escalation Issue 5|Issue 5]]''</ref>  A [[Kig-Yar]] [[Kig-Yar pirate queen|pirate queen]] operating on [[Ven III]] used an ''SDV'' corvette as her personal flagship, until its destruction in [[Operation: WHISTLE STOP]].<ref>'''Halo: Escalation''', ''[[Halo: Escalation Issue 12|Issue 12]]''</ref> The [[Banished]] also maintained the heavy corvette ''[[Elegy's Lament]]'' in their fleet,{{Ref/Reuse|hp}} which was used by the faction to raid and harry in its formative years.<ref>'''[[Halo: Rise of Atriox]]''', ''[[Halo: Rise of Atriox Issue 4|Issue 4]]''</ref>

==Production notes==
{{Linkbox|gallery=yes|gallerypage=Images of SDV-class heavy corvettes}}
{{Quote|For Reach's corvette, artist Glenn Israel created something new yet familiar using motiffs from the Covenant cruiser.|Frank O'Connor<ref name="abw73">'''[[Halo: The Great Journey: The Art of Building Worlds]]''', ''p. 73</ref>''}}
The ''SDV''-class heavy corvette made its visual debut in the [[2010]] game ''[[Halo: Reach]]'', playing an integral role in the [[campaign]] level ''[[Long Night of Solace (level)|Long Night of Solace]]'', as well as serving as the setting for the [[Firefight]] map ''[[Corvette (map)|Corvette]]'' and the multiplayer map ''[[Zealot (map)|Zealot]]''—both taking place aboard the corvette ''[[Ardent Prayer]]''. For the game, the corvette was conceptualized and designed by artist Glenn Israel, who attempted to create a new, yet familiar, ship class. The corvette's design was partly inspired by the {{Class|CCS|battlecruiser}}, particularly ''[[Truth and Reconciliation]]'' which had previously served as a setting for ''[[Halo: Combat Evolved]]''. While the corvette's interior resembles that of the battlecruiser, the increased processing power of the [[Xbox 360]] allowed for significantly more detail.{{Ref/Reuse|abw73}} The design of the ''SDV''-class corvette for ''[[Halo: Fleet Battles]]'' was achieved without using the ''Halo: Reach'' model for reference. The {{Class|ORS|heavy cruiser}} (which was designed for the game) features a "runner" amidships in reference to the corvette.<ref name="canon fodder">[https://www.halowaypoint.com/en-us/community/blog-posts/canon-fodder-in-the-loop '''Halo Waypoint''': ''Canon Fodder: In the Loop'']</ref>

In the campaign level ''[[Long Night of Solace (level)|Long Night of Solace]]'', the player's [[Sabre]] is able to destroy a corvette's engines and laser turrets, encountering no resistance from shields.{{Ref/Reuse|LNoS}} A corvette in ''[[Exodus]]'' is also crippled with a single missile barrage, again without any prior attack to shields.{{Ref/Reuse|Exodus}} In addition, several missiles from [[Sundered Legion Prowler|a]] [[Prowler]] during the [[Battle of Meridian]] caused enough damage to force a corvette to retreat.{{Ref/Reuse|HBB24}} This stands in contrast to the {{Class|CCS|battlecruiser}} in the final level, whose shields render it immune to damage until it exposes a weak point. However, later media ''[[Halo: Hunters in the Dark]]'', ''[[Halo: Fleet Battles]]'', and ''[[Halo: Warfleet]]'' all make reference to the ''SDV'' class being equipped with energy shielding.
