Morsam-pattern Seraph

The Type-31 Exoatmospheric Multi-role Fighter, otherwise known as the Seraph, is a widely used Covenant starfighter, essentially the Covenant's counterpart to the UNSC's Longsword interceptor. The Seraph is the successor to the older Tarasque-class fighter. A more powerful counterpart to the unshielded Type-27 XMF, it serves as the Covenant's primary superiority fighter.

Design details
The Seraph features a piscine, teardrop-like shape, fitting with the overall design elegance the Covenant is known for. Seraph fighters are mostly stored in the hangar bays of Covenant ships or stations when they are not in battle or escorting a ship. Seraphs have two movable flaps on either side of their hull, and their twin "tails" are articulated to aid with directing exhaust. These features give the Seraph superior turning capabilities in zero-gravity environments.

As the Covenant's main space-based attack fighter, the Seraph is highly maneuverable while in space, and can easily keep pace with the UNSC's Sabres and Longswords. Though not specifically intended for in-atmospheric use, Seraphs still are significantly faster than Banshees while flying at low altitudes. They have even been shown to fly in the hurricane force winds of the gas giant Threshold. The Seraph also appears to be able to power down and become invisible to Human ship sensors. This has proven to be extremely useful for sneaking past ship defenses undetected.

Armaments
Seraphs have demonstrated that they are a very effective counter-weapon against Longsword interceptors unless the latter attacks from the side or behind. Seraphs usually attack in formations of ten, their assaults on enemy ships range from simple harassment, to full out strafing attacks. They have also been seen patrolling in pairs. Unlike the Banshee or Phantom, Seraphs are equipped with energy shields, but these are only a fraction of the strength of those on Capital Ships and are easily depleted with sustained fire. It is assumed that Seraph fighters can be piloted by a single Sangheili, succeeded by the Jiralhanae after the Great Schism.

The Seraph is armed with a variety of weapons. Seraphs are seen firing a heavy plasma cannon, and are also armed with a pulse laser and plasma charges for strafing and bombing runs. A Seraph's bombing runs are very deadly, as evidenced in the SPARTAN-IIIs' attempted destruction of a Covenant factory as read in Halo: Ghosts of Onyx. The energy weapons the Seraph is equipped with delivers a hard punch to anything it attacks, such as Pelican dropships, and Albatross heavy dropships, and when dueling with the UNSC space-superiority Sabres.

Operational history
Seraphs have been seen operational as early as the Second Battle of Harvest. They are a common adversary of the Longsword fighters. These starfighters provided excellent fire support to all Covenant forces in space and on the groundside. Seraphs were prominently used during the Raid on the Third Fleet of Glorious Consequence, the Fall of Reach, the Battle of Earth, the Battle of Onyx, and the Battle of Installation 00.

In Operation: TORPEDO, the Seraphs harassed the incoming SPARTAN-IIIs by bombarding them during the UNSC surprise assault of the Covenant refinery facilities. Several fighters were shot down by missiles fired from the M19-B Surface-to-Air Missile Launchers used by the SPARTAN-IIIs.

During the Battle of Reach, the Seraphs attempted to disable the UNSC ships and orbital stations over the planet Reach, while providing some cover for the Covenant boarding crews. These attempts were subsequently prevented by UNSC Sabre-class interceptors, frigates and Longsword interceptors. Similar tactics were also employed during the Battle of Earth.

Trivia

 * The Seraph is actually an old model of a Covenant tank that Shi Kai Wang created.
 * Instead of having a name that represents a sinister supernatural being like the Wraith or Phantom, the word "Seraph" is derived from the highest level of angels as described in certain texts of the Bible. However, Biblical seraphim have six wings while the Type-31 XMF has none.
 * In the level Long Night of Solace if the player's highest kill is the Seraph when viewed in Campaign Scoring, the picture shown will be that of the Sabre.
 * Additionally in the same level, there is a glitch that makes it possible to hit a Seraph with an EMP shot from a Plasma Pistol and hijack it.
 * In the firefight map Corvette, upon exiting the initial spawn room, if you look on the roof of the opposite side of the main Hangar, you will see Seraphs hanging from the roof. They are not easily noticeable and you might need to turn your night vision on to see them.
