The Thofsin-class was a type of Andorian Empire starship, a cruiser in Andorian Imperial Guard service in the 22nd century. The Thofsin vessels were combatant vessels on the side of the Coalition of Planets allies during the Earth-Romulan War. Entering service on reference stardate 0/9902, 415 vessels of the Thofsin series were built over the next 18 years. After the Federation was founded, many of these cruisers joined the nascent Federation Starfleet. (FASA RPG module: The Romulan War)
