Star Trek First Contact
Episode: MOV 008 - Star Trek: First Contact

This class of Federation starship entered service during the late 24th Century. A unique design element of this class is how it streamlines the warp nacelles into the saucer section.

The U.S.S. Appalachia was a Steamrunner-class vessel, one that defended Earth during the Borg invasion of 2373.
