Atlas Class Heavy Frigate:
While Lacking a Scout MAC that its smaller counterpart the Aegis Class Frigate possess the Atlas has one capability that no other ship in the fleet has, it can Hover in atmosphere thanks to its massive Vertical Lift Engines. If it had a MAC the weight of the weapon would unbalance the ship in atmosphere. While Capable of flight it is still not capable of Escaping into orbit without help from the mass driver at Pendragon Military Base.
1(2x) Medium Mass Driver Battery
4(2x) Light Mass Driver Batteries
6(2x) CIWS Batteries
Length: 330 meters
Theia Class Electronic Warfare Frigate:
While Not As Capable as most frigates the Theia posses one weapon no other ship does, the ability to scramble any form of radar and communications. While this may not sound as deadly as 4 massive Assault class MAC just think about the confusion and disarray that would ensue if an entire fleet of ships suddenly lost communications and radar.
Cool designs on both ships, I really like the agresive look of the second. However, it's possible to defeat jamming, and ships can still detect ships by other means than radar, and can still communicate using stuff like tight beam communication. Still, good idea, it should be useful.
