Section VII: Editors Notes

The Mk. I Excelsior was a testbed for the Transwarp Project which ultimately failed.  The overall design of the ship was sound enough to have the project redesigned without Transwarp and had a long production run.  By the 2370's there were upgraded Excelsior Classes still in operation.

Known Ships in this Class:

USS Excelsior
