USS Yeager
From Star Trek: Theurgy Wiki
The USS Yeager was a 24th century Federation Saber class starship operated by Starfleet.
In 2373, the Yeager fought against the Borg in the Battle of Sector 001. (Star Trek: First Contact) Nolak Kalmil’s first posting was aboard the Yeager where he served from 2354 until 2362, when he transferred to the USS Excalibur. ([USS Yeager (NCC-61947) | Memory Alpha | Fandom powered by Wikia: Source: Memory Alpha]) Chief Petty Officer Nolak Kalmil was serving as a Starfleet Academy instructor at the time, but he volunteered for duty aboard the Yeager when he heard about the Borg. During the battle the Yeager’s senior officers were incapacitated, forcing CPO Kalmil to take temporary command of the starship.
