Warrior-class destroyer

The Warrior-class destroyer was a class of guided missile destroyers in service with the United Nations Space Command, which saw extensive combat throughout the Swarm War. The Warrior-class replaced a number of outdated -era destroyer classes, and was designed to take on the roles of each of these classes, as well as, and accomplish them with a single, versatile destroyer class. The Warrior-class destroyer and the lighter Vanguard-class destroyer together filled the UNSC's destroyer requirements with two versatile, multirole warships, rather than a larger number of less adaptable ship classes.

The Warrior-class destroyer served through most of the 27th century, seeing extensive action through the apocalyptic Swarm War which gripped the galaxy from 2633 until 2678. During the war, the destroyer's exemplary capabilities were affirmed as it regularly engaged larger and more numerous Swarm vessels with success. This success was the result of a combination of factors; relatively high speed, expansive armament, good endurance and heavy armour combined to form a potent and capable warship.

Although notably larger, the Warrior-class destroyer's design and layout was based on that of the Remembrance-class frigate. At 614 metres long, the Warrior-class was the biggest vessel ever classified a destroyer by the UNSC Navy. It was also one of the most well armoured ships in service relative to its length; a minimum of 1.5 metres of armour plating meant its mass was nearly twice that of the Remembrance-class frigate. A total of 4,602 ships of the Warrior-class were produced during its service life.
