Galaxy
The Galaxy-class is the result of an ambitious development program at Utopia Planitia Fleet Yards.  It is the largest and most complex starship built to date.  The Galaxy-class is primarily designed to replace the aged Ambassador and Oberth classes in research missions.  Galaxy-class starships feaure a detachable and independently operational saucer section, three shuttlebays and a captain's yacht at the bottom of the saucer.
