Arcturus class

The Arcturus class was a type of starship fielded by the during the 24th century.

While very similar to the design of several Starfleet vessels, most notably the Excelsior- and Galaxy-class starships, the Arcturus class has several unique features which aid in their mission of far-reaching exploration and diplomacy. The warp nacelles, an improvement on the Galaxy-class design, are sleeker and more angular and can propel the starship at speeds of up to warp 9.995 for extended periods. However, the most unique feature is the primary hull. Unlike most other starships, the saucer is divided into pie-wedge-shaped sections which can be easily removed and replaced at most any Starfleet facility. Each wedge section can be configured to contain laboratories, cargo bays, crew quarters, recreation facilities, weapons and defensive systems or any other equipment the starship may require during its mission, allowing the Arcturus to be configured precisely as needed for its current mission. Also, in case of emergency, each wedge section can be employed as an autonomous lifeboat. The average crew of the Arcturus included over 1000 officers and enlisted, up to 500 family members in the years before the Dominion War, and up to 500 additional mission specialists, depending on the requirements of the current assignment.
