International destroyers

In the years prior to the formation of the United Nations Space Command, nations and associations of nations built several military escort craft that were generally referred to as "destroyers." Following the Jovian Moons Campaign and the deployment of warships under the general command of the United Nations Space Authority, most national forces remained within the UNSA's oversight. They were eventually fully consolidated and commissioned into the new UNSC on January 1, 2164.

==Destroyers==
The destroyer designation was introduced in 2105, alongside cruiser, patrol ship, patrol craft, and destroyer tender designations. The fleet further clarified the roles of destroyers in 2114 with the introduction of the heavy destroyer and light destroyer designations, with the latter intended as frontline combat ships and the latter intended for escort and other supportive roles. Lastly, the recommissioning of the destroyer Allegiance in 2150 officially introduced the super-heavy destroyer designation as a warship intended to be capable of outfighting a quartet or more of contemporary heavy destroyers.
