In the mirror universe the Excalibur-class ships were the Terran Empire equivalent of the Federation's Ambassador-class. They had a specially designed transporter in the shuttlebay to beam shuttlecraft into other universes. (The Final Days)
The original design for the Excalibur class was created by Steven Davis.
