The Constitution class cruisers are among the most renowned vessels of their time. Serving as both a research vessel and a cruiser, these ships performed their duties to perfection for the majority of the 23rd century. The Constitution class ships were an integral part of the buildup during “The Great Awakening,” from the outset the most versatile of all ships built for the expansion efforts. class starships included the acclaimed U.S.S. Enterprise NCC-1701.[1] During the time of Captain James T. Kirk’s celebrated first five-year mission of exploration, only twelve of these ships were in existence.[2] Constitution class starships used duotronic computers, based on designs developed by Dr. Richard Daystrom in 2243.[8]

Deck Configuration

Deck 1: Bridge
As on nearly all Starfleet vessels, the systems of the Constitution class, from the environmental controls to the weapons systems, are coordinated from the bridge, which is located at the highest point of the ship. The bridge on Constitution class vessels follows the same basic layout that has been in use for more than two centuries. The bridge is a large, round chamber, and the main duty stations are in the middle. Prior to 2269, Deck 1 was served by a single turbolift shaft which opened directly onto the bridge behind the science station. A standby turbocar could also be accessed from Deck 2. The area behind the walls of the bridge contained spacesuit lockers, a weapons locker, and a ladder to Deck 2. In 2269, a new bridge module design was implemented; virtually identical to the original bridge, it featured a second turbolift adjacent to the viewscreen. The refit configuration bridges all continued to feature two turbolifts at the rear of the bridge, and shared largely identical layouts, though panel interface details continued to evolve.
