The USS Sovereign (NCC-73811) (also registered as NX-90201 and NCC-17454) was the prototype for the Sovereign-class starships in service to Starfleet in the 24th century. She was commissioned in 2372 as the first of her class. She was the sister ship of the USS Enterprise-E (TNG video game: Bridge Commander; Decipher RPG module: Starships; Last Unicorn RPG module: The Price of Freedom)


In June 2370, the Sovereign was launched however, initial testing of the Sovereign's new additions to its defensive and offensive systems proved disappointing. Design flaws in the regenerative shields led to phase synchronization instabilities in the graviton polarity generators powering the upgraded shields. The enhanced deflector system, which was upgraded with a new gravimetric distortion package, required extensive amounts of power that caused a drain on other essential systems. It was deemed too inefficient by Starfleet standards and the Sovereign was sent back to the Mars shipyards for storage and design reference. Many of these problems would be fixed by 2372 however. (TNG video game: Bridge Commander; SCE - What's Past eBook: The Future Begins)

From 2372 through 2375, Captain Montgomery Scott served as the vessel's chief engineer, part of that time under Captain George Sanders. The ship's chaplain during this time was named Blackwell. (SCE - What's Past eBook: The Future Begins)

Sanders must have taken command in 2373 or later, because prior to that he was in command of the USS Malinche, as per the DS9 episode: "For the Uniform".

The Sovereign's blueprints and schematics were incorporated into the USS Enterprise-E's computer systems. Unfortunately, many of the systems used aboard the Sovereign and Enterprise were different, especially offensive and defensive capabilities. (TNG eBook: A Sea of Troubles)

When the Sovereign was tested, the prototype regenerative shields failed. However, the Sovereign became the baseline for 2 anti-Borg design technologies: The regenerative shields on the Prometheus-class and the Defiant-class ablative armor. (ST video game: Bridge Commander)

Image of black hole "024 Gamma" recorded by the Sovereign.

In the year 2374, the Sovereign recorded data about the black hole designated 024 Gamma. (Starfleet Academy SCISEC Briefs episode: "SCISEC Brief 001: Mystery Behind Voyager")

The Sovereign was assigned to the Maelstrom in 2374 for research. In 2378, she was slated for a massive refit with an escort of 2 Klingon Bird-of-Preys. She was attacked by Romulan Warbirds who mistakenly believed that the destruction of the Vesuvi Star was the test-firing of a Federation weapon and that the two Sovereign-class ships were part of a Starfleet effort to claim the Maelstrom. During the attack, the Sovereign suffered minor damage but was saved by the USS Dauntless. She was later escorted to Starbase 12 by the USS Zhukov

Following the refit, the crew of the Dauntless was transferred to the Sovereign and helped by turning down the Cardassian rebellion. During the conflict, the Sovereign made first contact with the Kessok race and manged to destroy numerous Cardassian Galor-class and Keldon-class starships, as well as destroying a number of Cardassian stations, including the Nor-class Station, Litvok Nor. The Sovereign was part of the joint Federation-Klingon-Romulan-Kessok task force that launched an assault on the Cardassian controlled system Omega Draconis. After destroying multiple Cardassian Hybrid ships, and successfully contacting the Kessok colony on Omega Draconis III, she later pursued Legate Matans Keldon into a Solar orbit where she disabled his remaining Star-Destroying Probe and, later destroyed Matan's ship. She was assigned to the Maelstrom until the present. (ST video game: Bridge Commander)

In 2381, the Sovereign was docked at Starbase 22 following the Borg Invasion of 2381. (ST novel: A Singular Destiny)

Following the Undine attack on the Sol system in early 2410, the Sovereign was assigned as part of a permanent picket guarding Earth Spacedock. (ST video game: Star Trek Online)

Alternate timeline[]

In an alternate timeline, the USS Sovereign was Jean-Luc Picard's command, in place of the USS Enterprise-E. (TNG novel: Q & A)
