UNSC Frigate or Destroyer

Scale drawing of the UNSC Frigate of Halo 2/3 to my previous deviation, the UNSC Concordia-class carrier. No official name has been given to the class.

Also note that in Halo: The Fall of Reach, the UNSC Destroyer is nearly identical to the frigate, except it is seven meters longer, twice the mass and has more battleplate, and that it does not boast an air wing.

Examples of Canon Frigates:
UNSC In Amber Clad FFG-142
UNSC Aegis Fate FFG-307
UNSC Forward Unto Dawn FFG-201

Examples of UNSC Destroyers:
UNSC Iroquois
UNSC Glasgow Kiss
