Four-nacelle starships are not easy to build, which is why there have been only two designs. The Constellation class offered somewhat of a benchmark for the Cheyenne to use, but calibration still took almost a full year after the lead ship was launched in 2354. The vessel reached a speed of Warp 9.4 before hull stresses reached serious levels.
The Cheyenne class bears a striking resemblance to her Constellation class forebear. This is deliberate, as the Constellation design worked and the ASDB did not want to "mess with a good thing". The nacelles were specially designed for the Cheyenne, in an attempt to better harmonize the warp fields generated. The primary hull bears a striking resemblance to that of the Galaxy class, though it is much smaller. Some serving on a Constellation would marvel at the new staterooms aboard the Cheyenne. The wide elliptical primary hull allows room size almost 75% larger than those found aboard the Constellation. The sensor, survey, and scientific suites were the most advanced of their time.
Four warp nacelles were added. At it had with the Constellation class, this required the fitting of a larger warp core, which then tied together to provide balanced operations through a unified "H"-shaped intermix chamber system. The Cheyenne's warp enginer has proven to be a highly reliable design - a desirable trait in a deep-range explorer.
The Cheyenne is surprisingly lightly armed considering she is designed to operate so far from support. However, the Frederation of the Cheyenne's time was a far quieter and peaceful place than when the Constellations's plied the spacelanes. Three Type IX phaser arrays and two photon torpedo launchers are carried, along with basic deflective shielding.
The isolinear-chip based M-13 series of computers were custom built for the Cheyenne class, as the existing duotronic-based M-12 was too large and smaller, earlier models did not have the computing power or storage capacity to meet the stated requirements.
