USS Ranger
From Star Trek: Theurgy Wiki
The USS Ranger was a 24th century Federation Fredrickstad-class starship operated by Starfleet. During the 2370's the Fredrickstad-class shuttle carrier was considered obsolete and ships of the class were in the process of being retired. During the early 2370's, the Ranger was being used as a training vessel for war games involving small craft such as armed shuttles, gunboats, and fighters.
In mid-2370, Lieutenant Marcus Alexander Slayton was transferred from the Columbia to the Ranger and served as its chief tactical officer and Second Officer until 2372.
(It is unknown if the Ranger was still serving in 2381, but it more likely that it was decommissioned, since Starfleet would have decommissioned many older starships after the Dominion War.
