Halberd-class light destroyer

The Halberd-class destroyer is a class of destroyer in service with the UNSC Navy with a hull classification symbol of DD. The Halberd class was in service with the Navy during the Insurrection, throughout, and after the Human-Covenant War.

Superstructure and hull
The Halberd-class destroyer features a distinctive "arrowhead" profile. The hull of the Halberd class is reinforced with approximately two meters of titanium-A armor, with parts of the hull featuring components made up of vanadium steel. The hull is embedded with thermal superconducting radiators to more efficiently transfer the heat generated by the destroyers into space. At 485 meters in length, the class is only seven meters longer than a, yet it has almost double the mass at 7,900 metric tons; this is due to the destroyer's thick titanium hull that allows destroyers of this class to take a tremendous amount of damage. The destroyer has six emergency thruster tanks strategically placed on hardened points of the hull. Fast and requiring only a small crew, Halberd-class destroyers do not have as much armor as larger warships within the UNSC fleet. Though they lack general-purpose utility, the destroyers' heavy armaments compensate for this issue. The Halberd class has a modular design which allows them to be configured for different missions.

Halberd-class destroyers are powered by high-thrust fusion drives located at the aft, with four primary and four secondary drives. Translight power is provided by a Shaw-Fujikawa Translight Engine, located in the destroyer's expansive engine room. The aft of the Halberd class has reinforced armored screens fitted to protect fusion drives and the slipspace engine. Halberds are also equipped with an advanced sensor array, the Mk. 45 long-range fire director. The destroyer class has a circular bridge with an array of display monitors for its crew. Later into the Human-Covenant War, Halberd-class destroyers were outfitted with an ε-pattern layout, providing an increased field of view. The crew quarters are cramped with limited recreational facilities. The hangar bay of the Halberd class is small and confined, with little maneuvering room for shuttlecraft. The hangar is reconfigurable with an electromagnetic catapult launch assist that can quickly deploy shuttlecraft. Unlike most warships of the UNSC Navy, they do not carry space fighters. They do, however, carry several D77-TC Pelican dropships. Each destroyer of the class has two armories, each filled with an assortment of firearms and equipment.

Armaments
Though these destroyers are not as heavily armored compared to other warships in the Navy's fleet, they are armed with enhanced weapons systems that make up for their relatively light defensive capabilities. The Halberd-class destroyer's primary armament is a spinal-mounted 14B11R2 MAC Battery, which is composed of twin-linked 1170mm/647mm high-velocity coilguns. The Halberd class is also armed with twenty-six oversized Archer missile pods, capable of holding a total of over eight hundred Archer missiles. The class also holds a payload of three Shiva-class nuclear missiles. For defense against single ships, the destroyer class carries eight twin-linked 50mm point-defense autocannons. One of the most heavily armed classes of UNSC vessels, a group of Halberd-class destroyers is capable of engaging and inflicting heavy damage upon even the largest of Covenant ships.

Operational history
The Halberd-class destroyer was the most commonly deployed destroyer class during the Human-Covenant War and the later years of the Insurrection. Such vessels were in service as early as 2517 and continued to serve throughout the Human-Covenant War. Despite their powerful armament and maneuverability, many fleet officers looked down upon destroyers, considering them too ineffective against Covenant ships. It was generally agreed that seven destroyers were an even match for four Covenant frigates.

Though Halberd-class destroyers can be configured for a variety of mission types, resource shortages during the Covenant War led to most Halberds only being configured purely for escort duty, with entire subsystems left out to reduce construction time. At some point between 2548 and 2552, one destroyer of this class,, participated in the Battle of Algolis, where it destroyed five Covenant ships when it initiated its self-destruct fail-safe. Many Halberd-class destroyers participated in the Battle of Sigma Octanus IV, most notably, which was captained by Commander Jacob Keyes. During the battle, Iroquois performed the daring Keyes Loop, destroying three Covenant vessels in the process. Several dozen destroyers later participated in the Fall of Reach. This destroyer type continues to be in service with the Navy by 2557, with some serving with the UNSC Home Fleet over Earth.
