Here are just a few ship designs I have come up with for my story:
Apollo Class: A formidable vessel that combines the strengths of a fast attack destroyer with the long range strike ability of a light carrier. The apollo carries 3 full wings of VF-11 thunderbolts(12 planes per wing) as well as a battalion of anti air destroids to support its point defense. Apollos work best when acting as part of a battle group
Specter Class: A Stealth craft designed for advanced recon and black op missions. The specter has the most advanced long range sensors of any vessel within the U.N.'s battle fleet. It is equipped with advanced jamming sensors to distort enemy communications and targeting systems. With light armor and minimal armaments, the specter relies on it's speed and stealth as a weapon. The specter is a integral part of any battle group as they are the eyes and ears of the fleet.
Maximillion Class: The work horse of the U.N. fleet, the maximillion is a front line battle cruiser that delivers heavy fire power with a mix of durability and reliability. The Maximillion's Bow firing Heavy partical cannons are capable of delivering devastating damage to enemy craft, and combined with it's ability to launch reaction warheads, makes the maximillion a force to be reckoned with. It's one weakness is it's lack of effective point defense, there for it works best when paired with Apollos
strike carriers to defend it from enemy fighter craft.
