CONSTITUTION-CLASS STARSHIP  
U.S.S. ENTERPRISE NCC-1701  
U.S.S. ENTERPRISE NCC-1701-A  

USS Enterprise-A In 2220, the Federation Council formed the Starship Design Bureau (SDB), a division of Starfleet, to oversee design and construction of new Starfleet starships. The Constitution-class vessel was co-designed by Vulcan and Earth. The first Constitution-class starship construction began in 2225 at Earth's San Francisco Fleet Yards. The starship was designed with two primary goals: deep-space exploration and to defend the Federation from the Klingons, Romulans, and Tholians.

Constitution-class starships used duotronic computers based on a design developed by Dr. Richard Daystrom in 2243. The computer operating system is usually referred to as the Duotronic Computer Library Database (DCLD).

The U.S.S. Constitution, Starfleet registry NCC-1700 was commissioned by Starfleet in 2343, commanded by Commodore Matthew Decker. The U.S.S. Enterprise NCC-1701, the first production vessel, was commissioned in 2345, under the command of Captain Robert April, then Captain Christopher Pike, and finally Captain James T. Kirk in 2264.

Due to advances in starship development, the Constitution-class vessels were slated to receive a major refit in 2269. The refit of the Enterprise NCC-1701, supervised by Captain Willard Decker, began in 2269 and completed in 2271. After the success of the Constitution, design of the Excelsior-class began.

The U.S.S. Enterprise NCC-1701 was destroyed at the planet Genesis in 2285. James Kirk ordered the auto-destruct to prevent the ship from being captured by the Klingons. The refit U.S.S. Yorktown NCC-1717 was recommissioned as the U.S.S. Enterprise NCC-1701-A and command was transferred to Captain James Kirk.

All Constitution-class starships were decommissioned from active service by 2295.
