The Evacuationstar is one of the most secret projects of the Colonial Fleet. Developed in the early stages of the First Cylon War when the probability of defeat loomed large for the Twelve Colonies. Developed and funded in secret it was decided that knowledge of this project would cause grave harm to the morale of the people and the armed forces of the Colonies. They are based upon enlarged version of the Poseidon Class Battlestar developed by the Ravenstar Corporation; however, they are much longer, wider, and deeper. Designed to evacuate a large percentage of the population should defeat become inevitable each Colony was to have no less than two each. It was intended to be able to evacuate as much of the remaining population from all of the Colonies as physically possible with what time and available space could provide. A total of ten were begun before the project was cancelled and the money and resources were funneled into other military project which eventually led to victory. Kept hidden the existence of the four ships that were operational was maintained as a military secret known only to those with the highest clearance and a need to know. Two of these ships were seized by Anderian Forces in the later part of their coup attempt as that Civil War turned against them. The Evacuationstar differs from most colony ships in its ablity to offer a very credible self defense (although in no way can this ship be considered a combatant) and the fact that the colonist (or evacuees) live inside the ship itself and not in the agrodomes.
The ship boasts:
6 water storage globes
Port side docking facilities for larger ships from either their escort fleets or for resupply
4 livestock domes
3 environmental domes for evacuee use
dozens of smaller agrodomes for food production
2 oversized hanger pods for utilitarian vessels to develop any chosen colony site
2 oversized hanger pods converted into manufacturing and industrial facilities
8 small cruiser sized "lifeboats"
and
integral Viper and Raptor squadrons (although these craft date back to the First Cylon War)

Their size makes them an almost static target and their dradis signature can be seen for parsecs; especially their jump footprint
