The Galaxy-class is one of the largest most advanced and powerful ships in Starfleet. The Galaxy was developed at Utopia Planitia and began service in the year 2357. The Galaxy was design for long term deep space missions, which includes scientific exploration, diplomatic and defense duties.

Galaxy-class ships have 42 decks, a habitable area of 800,000m2, and a spaceframe design of 100 years. Because of the families onboard its saucer separation procedure helps greatly in getting civilians out of harms way in hostile battle situations. There are three shuttlebays, one on the saucer section, and two on the neck large enough to carry Danube-class runabouts.

The production and amount of the Galaxy ships have greatly increased since the Dominion War. Further production of the class will remain for the forseeable future.

Gene Roddenberry once speculated that there were only six Galaxy-class ships built and that the Enterprise was the second constructed, but this has not been firmly established in an episode. The Galaxy-class model, the Enterprise-D, was was designed by Andrew Probert. Interior sets were supervised by Herman Zimmerman and Richard James.
