This ship was active on the Klingon border in 2288, and engaged two Klingon B'rel-class Birds-of-Prey when they violated the Federation border. The Sentinel stood her ground and chased them off, but the Federation Council later apologised to the Klingons for the Sentinel's actions. (TOS video game: Starfleet Academy)
- This ship was seen in-game on a "news broadcast" to the cadets at Starfleet Academy. No name or registry number was seen on her hull, but the voice-over for the report indicated she was named Sentinel.
