This is ship is far and away the most appealing design I've ever built. It has multiple versions for multiple mods and a vanilla build, but I think the Kroom's and automation+ build is the best one mechanically.
Designed for durability above all else, the improved Eagle Class Destroyer by Mekwerks INC now comes standard with paired reactors and heavy duty ion cannons to counteract the energy shielding systems often employed by the opposition. The Eagle Class is now the backbone of the Earth Defense Fleet.
