The Walker class was a 23rd century Federation starship type, a light exploration cruiser in Starfleet service from the 2220s decade. (DSC episode: "Battle at the Binary Stars", STO website: Jayce's Interstellar: Walker Class Crash Mobilization)

Technical data

The Poseidon-class USS Coto in 2159.

This class entered service in the 2220s decade with the launch of the USS Walker (NCC-1202) in the year 2221. Advances in propulsion technology soon made it near-obsolete, and a number of these vessels had been mothballed by the 2250s. (STO website: Jayce's Interstellar: Walker Class Crash Mobilization)

The ship's structure was based on the 22nd century NX-class starships but with a length of 423 meters significantly larger. (The Official Starships Collection Issue DSC issue 1: "USS Shenzhou")

In the 2150s and 2160s, Poseidon-class had been an early variant of the NX class. Its physical arrangement anticipated future Starfleet hulls. (ST video game: Legacy, ENT - Rise of the Federation novel: Live by the Code)

Physically, a vessel of the class included a saucer section with a navigational deflector integrated in the bow, and, atypically for a Starfleet vessel, a bridge at the bottom of the saucer. A compact secondary hull was attached to the rear of the saucer, and sat between a pair of nacelle pylons with one warp nacelle each. A Walker had 15 decks. (DSC episode: "The Vulcan Hello")

By 2255, at least one Walker-class starship, the USS Shenzhou, had been in service for decades. Lagging behind in technical upgrades, it was not a match for an up-to-date Constitution-class heavy cruiser. (DSC novel: Desperate Hours)

This ship class was capable of atmospheric flight by means of thrusters scattered over its hull. It carried shuttlecraft and worker bees, as well as escape pods. It was equipped with lateral vector transporters. (DSC episodes: "The Vulcan Hello", "Battle at the Binary Stars")

The ship's armament included phase cannons, phasers, and photon torpedoes. (DSC episode: "Battle at the Binary Stars")

Service history

Hovering in the atmosphere.

By 2249, it was considered an aging design. (DSC novel: Desperate Hours)

A ship of this class, the Shenzhou, was lost in the Battle of the Binary Stars on 11 May 2256.

Six months later, a picture of a Walker adorned a mess hall wall of the USS Discovery. (DSC episode: "Context Is for Kings")

In 2256, Starfleet Command directed Federation shipyards Yards 4, 32 and 39 to pull Walker-class ships from mothballs to partake in the Federation-Klingon War. This included the USS Walker. Vice Admiral Katrina Cornwell directed Bureau of Personnel to staff these vehicles with young officers. (STO website: Jayce's Interstellar: Walker Class Crash Mobilization)

Following the transfer of Starfleet and House of Mo'Kai ships and personnel from 2257 to 2409, the Walker-class returned to service again. (STO - Age of Discovery mission: "Downfall")
