“Trek Registry Series - U.S.S. Excalibur Logo” T-Shirts & Hoodies by Christopher Bunye | RedBubble
Here, we see an example of a ship that’s not a regular Starfleet Vessel, but one from the “Star Trek: New Frontier” series of books. The Excalibur, commanded by Captain MacKenzie Calhoun, patrols a distant part of a recently destabilized area of space. This ship commemorates the second Starship Excalibur, which is a Galaxy Class vessel, named and numbered in honor of her Ambassador-Class predecessor, which was lost in an inexplicable manner, but not before her crew escaped.
