The Thanatok was a Federation Starfleet starship in service in the late 22nd century. It was a cruiser.
The vessel was crewed entirely by Andorians with an overzealous captain. On reference stardate 1/1209.12 (circa 2186), the Thanatok attacked and destroyed an Orion pirate enclave at Brurem. However, a number of civilians were also killed.
The Botchok Planetary Congress protested the civilian deaths, and the Federation punished the Thanatok's captain. (FASA RPG module: The Orions: Book of Common Knowledge)
- As an early Starfleet vessel with no "USS" prefix name (these are always included in the source) and an entirely Andorian crew, the Thanatok is likely to be a former Andorian vessel included in the newly formed Starfleet. It may be part of the so-called "Blue Fleet" of Andorian-crewed Starfleet vessels.
