Ouroboros class

For other uses, see Ouroboros.

The Ouroboros class was a 31st century Federation starship class, a temporal raider and variant of the 29th century Wells-class timeship, in Starfleet service during the Temporal Cold War.

History and specifications[]

The Wells-class USS Relativity and its sister ships^[1] were active in the 2870s decade. (VOY episode: "Relativity") The USS Pastak temporal science vessel was involved in the Temporal Wars as well. (STO - Future Proof missions: "Temporal Ambassador", "The Temporal Front")

In that time period, protecting the timeline was the mission of Starfleet and the Temporal Integrity Commission. (VOY episode: "Relativity")

The USS Ouroboros entered service in the 31st century. Like the Chronos-class temporal dreadnought and the Eternal-class multi-mission explorer, the Ouroboros was designed for cross-temporal engagements during the Temporal Wars. Structurally, all three classes were based on the Wells-class active in the 29th century. (STO - Agents of Yesterday mission: "Welcome to Earth Spacedock", STO website: Agents of Yesterday: 31st Century Ship Stats)

It was named for the "ouroboros" concept of Earth mythology. (DS9 - The Lives of Dax short story: "Allegro Ouroboros in D Minor")

This 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. (STO - Agents of Yesterday mission: "Welcome to Earth Spacedock", STO website: Agents of Yesterday: 31st Century Ship Stats)

The Ouroboros was armed with antiproton banks, cannons, an antiproton turret, and chroniton torpedo launchers. As a combat-oriented timeship, it was able to fire a molecular deconstruction beam at enemy targets. Its tactical system stabilizer temporarily improved weapon performance by hastening energy cycles. Defensive systems included deflector shields and a cloaking device.

The temporal raider was highly maneuverable and able to perform flanking maneuvers unique to raiders. Overall, the ship's design and capabilities were a marriage between the Wells class and the venerable Klingon bird-of-prey of centuries past. (STO - Agents of Yesterday mission: "Welcome to Earth Spacedock")

Due to the opening of a new front of the Temporal Cold War in the year 2410, the Temporal Integrity Commission and Temporal Agent Timot Danlen worked with Khitomer Alliance authorities native to the 25th century. Some commanding officers of that time were recruited as temporal agents, and given access to starship classes of the 26th and 31st centuries. This included the Ouroboros class. (STO - Agents of Yesterday mission: "The Once and Future Agent")

USS Elizabeth — USS *Elizabeth* at the Battle of Procyon V.

In the 26th century, Agent Danlen directed Ouroboros-class raiders to protect the USS Enterprise-J and engage the forces of the Temporal Liberation Front during the Battle of Procyon V. One of the raiders' captains was an unidentified Ferasan captain, whose ship was destroyed in initial permutations of the battle before the TLF reset the timeline several times. (STO - Agents of Yesterday missions: "Ragnarok", "Battle of Procyon V")

By the 3050s, temporal guardianship had transferred into the hands of a civilian Federation authority, the Federation Temporal Agency. (DTI novel: Watching the Clock)

Following the end of the Temporal Wars, time travel was banned and related technology dismantled. As a result, time travel was unavailable when the Burn occurred in 3069^[2]. (DSC episode: "That Hope Is You, Part 1")

Livery[]

In the 25th century, the design of the Ouroboros-class temporal raider allowed its commanding officer to choose from different designs of hull materials, which could be modified further at shipyards. (STO - Klingon War mission: "Welcome to Earth Spacedock")

The hull did not display the ship's name or registry number. (STO - Agents of Yesterday mission: "Welcome to Earth Spacedock")

Furthermore, the installation of deflector shields from specific factions modified the hull appearance, including shields from the Reman Resistance, the Breen Confederacy and the Dominion. (STO missions: "Coliseum", "Cold Storage", "Boldly They Rode")
