Temporal department patch

The temporal science vessel was a starship type developed by Federation Starfleet in the early 25th century due to learning about the 29th century iterations. Temporal science vessels were science vessels rated for time travel and designed to protect the timeline. Their mirror universe counterpart was the temporal destroyer. (STO - Legacy of Romulus missions: "Temporal Ambassador", "Spin the Wheel")

Due to increased Federation and Alpha Quadrant Alliance involvement in the Temporal Cold War in the early 2410s decade, older ship classes we refitted and returned to service as temporal-rated vessels, including the Daedalus-class. (STO video game: Agents of Yesterday)

History and specificationsEdit

The Alpha Quadrant Alliance first encountered the temporal science vessels during conflict with the Tholian Assembly in the Azure Nebula. The Tholians had captured starships from other time periods and timelines in order to gain an advantage. The Ferengi-operated Lobi Crystal Consortium found some of these ships, though stripped of their most futuristic technology, and sold them to AQA captains through the temporal lock box. (STO - Legacy of Romulus missions: "Temporal Ambassador", "Spin the Wheel")

In 2411, tier 6-rated versions of the 29th century temporal science vessels became available to AQA commanding officers by way of Lobi Crystal Consortium's infinity lock boxes. (STO - Season 14.5 mission: "Spin the Wheel")

While the Klingons and Romulans had joined the Federation by 2769, they continued to produce their own ships in the 29th century, including counterparts to Starfleet temporal science vessels. (STO - Future Proof mission: "Time and Tide", STO - Legacy of Romulus missions: "Temporal Ambassador", "Spin the Wheel")

In the 31st century, Starfleet fielded the Eternal-class temporal multi-mission science vessel. In response to the Temporal Cold War, this class of ship was made available to commanding officers in 25th century Starfleet, Klingon Defense Force and RRF. (STO - Agents of Yesterday mission: "Welcome to Earth Spacedock")
