Specifications - Constitution-class refit


In 2271, the USS Enterprise was selected to be the first ship to undergo a massive refit of the original Constitution class, and went into Earth spacedock for eighteen months of work. Never in Starfleet history, at the time, had any vessel been so comprehensively updated; essentially a new vessel was built onto the bones of the old replacing virtually every major system.

Once the Enterprise was through her shakedown cruise successfully the remaining Constitutions where refitted in quick succession. The new ships proved to be more than capable of carrying out their normal exploratory and scientific roles, while in the combat arena they where judged an easy match for the refit Klingon K'T'Inga class. The Constitutions continued in service, and once again the Enterprise set the standard for the rest of the ships to follow.

During the turn of the century the Constitution class proved to be a formidable starship on the frontier in both exploration and combat patrol. However the newer Excelsior Class starships proved to be too much to keep the Constitution class remaining in production. The remaining Constitution Class starships were all refitted to the new design by 2290, and production ceased with 24 starships of the class in service.
