The frigates that are employed by the Citadel Navy are similar in comparison to that of the SR-2 Normandy. The key difference that they have with the Normandy is that they are already equipped with devices that the Normandy would consider upgrades. These frigates, dubbed Normandy-class Frigates are equipped with Javelin Torpedoes, Thanix Cannons, Silaris Heavy Armor, Multicore Shielding, Helios Thruster Modules, a Modular Probe Bay, and an Argus Advanced Mineral Scanner.
