Class Overview

(From Haynes USS Enterprise Owners' Workshop Manual)

In the second half of the 23rd century, Constitution-class starships were in the front line of Starfleet's mission to explore the galaxy. They were tasked with supporting newly established colonies and research missions, exploring new worlds, and seeking out new life. They also patrolled the Federation's borders, ready to respond to hostile alien powers. All Constitution-class ships served with distinction, but the Enterprise NCC-1701 became the most famous.

Constitution-class ships were among the most advanced ships in Starfleet. They were fitted with matter/antimatter warp engines that gave them a regular cruising speed of Warp 6, and could maintain speeds of Warp 8 and above for limited periods of time. The class's structure was strong enough to survive speeds in excess of Warp 10 on the old warp scale (or around Warp 8 on the redrawn scale in use in the 24th century). The warp engines were the class's primary power supply, with the impulse engines offering a backup, but if they failed, these ships could survive on battery power for approximately a week.
