Avenger (NX-09)[1] was a 22nd century United Earth starship, an NX-class cruiser in United Earth Starfleet service from the 2150s decade.[1] Following the formation of the United Federation of Planets in 2161, Captain Shrun served as commanding officer of the USS Avenger[2].

Service history and disposition[]

The Romulan War[]

Avenger in 2159.

Avenger had entered service at some point during the Earth-Romulan War in the 2150s. Its registry number NX-09 identified it as the ninth ship of its class.

During the war, Avenger saw action against the Romulan Star Empire and its Imperial Navy by 2159.

In that year, following a hostile encounter with the Romulans during a mission on behalf of the Confederacy of Vulcan, Captain Jonathan Archer of Enterprise NX-01 was authorized by "Reggie" to requisition Avenger NX-09, Columbia NX-02, Currie NX-16, or one of the other available Earth starships for a mission to Research Station Gravenor. (ST video game: Legacy mission: "Breakwater")

No specific history or definitive final fate was established for this vessel as its name was selected for a scout by the Legacy game developers, and is sometimes placed randomly when the ship appears.


USS Avenger versus USS Tyson.

The Federation was founded in 2161, and United Earth's Starfleet was incorporated into the new Federation Starfleet. The Avenger received the USS prefix and was given to Captain Shrun, an Andorian and veteran of the century-long[3] conflict between the Andorian Empire and Vulcan.

With new NX-class ships in production, Starfleet launched a tactical training program for two new captains, Shrun and his Vulcan counterpart Sporik of the USS Tyson. Before the training began, the Avenger was in orbit of Lamda Paz. The ship's chief engineer reported in his log entry that programming the tactical exercise into the computer was successful but that there was concern about a resurfacing of the old rivalry between Shrun and Sporik.

During the exercise, an ion storm confused the sensors of both NX-class ships during their combat maneuvers among asteroids. Shrun became paranoid and suspected Sporik attacking Avenger for real. The crew could not differentiate between phaser fire and effects from the ion storm, but it was up to them to convince Shrun from assaulting the Tyson.

Mirror universe[]

ISS Avenger in 2155.

In the mirror universe, the ISS Avenger NX-09 enforced the brutal rule of the Terran Empire. This Avenger was destroyed in 2155 by Starfleet rebels controlling the time-displaced 23rd century Federation Constitution-class starship USS Defiant. (ENT episode: "In a Mirror, Darkly")


The USS Avenger in 2287.

Avenger was succeeded in name by the Miranda-class (Reliant-subclass) starship USS Avenger (NCC-1860) in the 23rd century. (TOS - DC second series comic: "Going, Going...")
