I've messed around with the first one.

UEN FF-031 'Javelin' Class Missile Frigate.
The Javelin was designed to be a fast-moving long-ranged missile platform to support small groups of Shortsword Frigates. Due to recent budget cuts, the Javelin was converted into a mid-to-long range warship and extra armor plating was added to the front and sides of the bow to increase its odds of survival against Altairian penetrator weapons. This addition sacrificed the Javelin's exceptional speed and maneuverability, assets that would have contributed more to its survivability than extra armor.

UEN FF-051 'Shortsword' Class Light Frigate
The Shortsword is the backbone of the United Earth Navy's Planetary Defense Force. It combines high-tech weaponry with a small profile and high speed. These warships were designed to operate in groups of four with long-range support to harass enemy formations while the larger Broadswords and Claymores maneuvered to deliver the full force of their broadside firepower.
