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 destroyer 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 between one-and-a-half to two meters of titanium-A armor, with parts of the hull featuring components made up of vanadium steel. 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. 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 this issue. The destroyers' modular design allows them to be configured for different missions.

Translight power is provided by a Shaw-Fujikawa Translight Engine, located in the destroyer's expansive engine room. The destroyer class has a circular bridge with an array of display monitors for its crew. The hangar bay of the Halberd class is small and cramped, with little maneuvering room for shuttlecraft. Each destroyer of the class has two armories, each filled with an assortment of firearms and equipment. Unlike most warships of the UNSC Navy, they do not carry GA-TL1 Longsword starfighters. They do, however, carry several D77-TC Pelican dropships.

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 is armed with two Magnetic Accelerator Cannons, twenty-six oversized Archer missile pods, and 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 the, 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.
