Ouroboros class

The Ouroboros class was a Federation starship class, a tier 6 temporal raider escort in Starfleet service in the 31st century. It was the more combat-oriented counterpart to the multi-mission explorer. The Ouroboros class was designed to strike fear in the heart of the Federation's enemies. Its potent weapon systems made it a valuable asset in the Temporal Cold War. All tier 6 starships required a commanding officer ranked vice admiral or higher.
