Excelsior-class
The Excelsior-class starship first appeared in Star Trek III: The Search for Spock. Nicknamed "the great experiment", the first vessel in this class was fitted with a new transwarp drive. The experiment was deemed a failure, and a standard warp drive was subsequently installed. The Enterprise B was a variant of the class. Later on, the USS Lakota was refitted with ablative armor, stronger phasers, quantum torpedoes, and a faster warp drive.
The ship class remained in service through the end of the TNG era, making appearances in large fleet actions and battles in both TNG and DS9.
