Stemming from President Sheridan's request for proposals concerning an enlarged version of the White Star that would be able to confront enemy capital ships on an equal footing, the Allegiance Destroyer is only 40% larger than a standard White Star. This heavy combat vessel fills the mission requirements that call for a ship more powerful than a White Star, yet does not befit a Victory.

The Allegiance has slightly more firepower than the White Star, but is much more versatile. Increased firepower over the standard model White Star allows the Allegiance an advantage when combating the enemy. The Achilles' heal power shortage was also corrected in this decendant of the White Star, allowing it to power all of its weapons and jammer both in a combat situation. The Allegiance can also operate six fighters, providing fighter support for other alliance ships.
