Paris-class heavy frigate

The UNSC heavy frigate is a form of light capital warship operated by the UNSC Navy. It saw use during the UNSC's twenty-seven year-long war with the genocidal theocracy known as the Covenant.

History
Prior to the Insurrection of the late 25th century, the concept of a "heavy" frigate was considered a gross misuse of the UNSC's funding. In the years following the coup d'etat on Eridanus II and the rebels' capture of the, there was much more support for a shake-up of the UNSC's relatively lax and ill-defended fleet. These upgrades would take effect during the disastrous Operation: TREBUCHET.

Design
The heavy frigate was essentially a more heavily-armored variant of the standard UNSC Frigate, equipped with more point-defense guns to provide stronger support in battle situations.
