The Paris-class heavy frigate is an escort class ship in the UNSC Navy. They are manufactured by Sinoviet Heavy Machinery. They are used by the Alliance of Nations. The Paris-class heavy frigate is more heavily armed and armored, designed for direct combat action rather than fleet support, with a larger complement of point-defense guns, Archer missle pods, and a lengthened Magnetic Accelerator Cannon for additional support. It lacks the vehicular deployment bay of the other two classes of frigates, but its heavier armament can handle enemy fighters and larger vessels. When fielded in larger numbers, Paris-class frigates can screen a formation, engaging Covenant frigates and destroyers while allowing more powerful UNSC destroyers and cruisers to focus fire on the larger Covenant cruisers and carriers.
