The ***Cheyenne*-class** was a type of spacecraft developed by Starfleet in the mid 24th century as part of the Century Cruiser Project.

## History

The *Cheyenne*-class was designed as an economical replacement for the aging *Constellation*-class using elements from the Century Cruiser Project. The class incorporated the project’s primary hull design and used nacelles akin to those of the *Springfield*-class. These were used instead of the newer ones piloted on the *Challenger*-class, due to many *Springfield*-class vessels being decommissioned at the time and the practicality of refurbishing their nacelles over adapting the new nacelle design for quad pairing. The USS *Cheyenne*, lead ship of the class, entered service in 2364.

After the Battle of Wolf 359, Starfleet Command created the Perimeter Defense Directive. This program was intended to design new starship classes that could be rapidly deployed to defend Federation planets and borders. Though the *Cheyenne* design was effective, it was sidelined in favor of classes like the *Akira* and *Steamrunner* that were developed under the program.

### Command systems

The *Cheyenne*-class pioneered a new bridge module designed for starships of the Century Cruiser Project. Designated the VAR-2, the interior had three tiers instead of the slopping flooring of the VAR-1 series. The lowest and foremost tier contained the consoles for the conn and operations stations. The command chair was centered on the middle level and was flanked by two additional chairs, the starboard being for the executive officer. Port of the command area and on the same tier were doorways to a turbolift and the commanding officer's ready room. These were mirrored on the opposite side by another turbolift and the entrance to the head. The aft most tier had five consoles, four of which were against the aft bulkhead. The fifth console, which was the tactical station, faced the viewscreen and was embedded in a railing the curved around the command area. Behind the tactical station was a corridor that led to another turbolift and the executive conference room.

The VAR-2 bridge module was the *Cheyenne*-class standard and was used in some *Galaxy* and *Nebula*-class starships, although it never found widespread use in those designs. New bridges were designed for *Galaxy* refits in the late 2370s and these new VAR-3 modules were eventually used in *Cheyenne* vessels as they were refit.

## Ships commissioned

Names of *Cheyenne*-class vessels were typically chosen from ethnic groups and vast open spaces of Federation members worlds.
