USS Typhon
From Star Trek: Theurgy Wiki
The USS Typhon a 24th century Federation prototype carrier vessel operated by Starfleet.
Tanithil Heilana’s first Starfleet post was aboard the experimental carrier USS Typhon one of the Federation’s attempts at a mobile outpost and carrier starship. He served aboard the USS Typhon from 2375 until 2379 with the rank of ensign. The USS Typhon would see little action in the final year of The Dominion War but was part of the mission to retake Betazed. Although the Typhon added to the concept for possible future mobile outpost and carrier starships, the flaws in her design wound up sealing her fate and she was mothballed in 2379.
