USS Aegis (NCC-7575) was one of the handful of Prometheus-class starships defending the Federation during the immediate aftermath of the Dominion War.
As is standard with this class, the Aegis boasted a multi-assault vector mode which allowed the ship to separate into three vessels, each with weapons platforms and capable of warp.
Launched in January 2376, under the command of Captain Terrence S. Glover, the Aegis performed admirably on patrol along the Cardassian border in the Lamenda system in February 2376, routing the True Way Cardassian insurgents in April 2376, and in dealing a major blow to the Crimson Shadow, another nest of Cardassian insurgents in the Crolsa system in May 2376.
Unfortunately, this would be the ship's last mission. It was destroyed in a daring suicide attack by the desperate Gul Sescal in orbit of the Bomos Mining Facility in the Crolsa System in May 2376. At the time of its destruction, it was under the command of Commander Geoffrey B. Thorne.
The ship's motto, "Deeds, Not Words" was chosen by Glover to honor the US 92nd Infantry Division, the famed Buffalo Soldier Division that fought with distinction in the Old Earth conflicts known as World War I and World War II.
