Diligence-class light destroyer

The Diligence-class light destroyer was a class of destroyer in service with the UNSC Navy and the Colonial Military Authority.

Operational history
The Diligence-class entered service in 2433. Originally classified as a cruiser, the Diligence-class was eventually reclassified as a destroyer as ships grew in firepower and mass.

Some Diligence-class destroyers were operated by the Colonial Military Authority as peacekeeping ships. By 2525, the class had been retired for decades. However, with the dawn of the Human-Covenant War, some were brought back into service with the UNSC Navy and were retrofitted for combat against the Covenant.

During or after 2540, a Diligence-class destroyer, the, deployed a squad of Orbital Drop Shock Troopers and a SPARTAN-II commando, Cal-141, via SOEIV to the Covenant-occupied planet Heian. The commando team infiltrated a former alien settlement, where they engaged several Unggoy and a Jiralhanae chieftain before assassinating a Covenant Prophet. After the mission, which resulted in the deaths of the Spartan and one ODST, the vessel retrieved the survivors.
