Another entry into this fun contest.
Something of a science vessel, having powerful sensors and advanced technology needed for the exploration and surveillance of planets, uncharted systems and enemy territories. Focusing on sensing/tracking/navigation modules with a monstrous computer, it can cover great distances and quickly inspect its surroundings.
Although a science ship, due it to the potentially hazardous nature of it's missions it is not lacking in firepower or defenses. It can easily survive small engagements alone, and escape before real trouble arrives, and can serve as a capable, if not improvised support ship when with a fleet. The Atlas possesses great energy capacity for intensive warping, and utilizing high-end modules for long durations, but lacks the sturdiness to contend with larger or more numerous ships for very long.
Or something like thatů I'm just glad to participate and see all the other awesome designs.
