Service history and disposition[]

Excalibur-1664 — The original *Excalibur*.

The namesake USS Excalibur (NCC-1664) was in service as a 23rd century Constitution-class heavy cruiser in the 2260s decade. (TOS episode: "The Ultimate Computer")

The modern Constitution-class starship Excalibur was active in the 3180s decade. At one point in 3189, this ship was docked at the Federation Headquarters space station, the joint home of the Federation's civilian government and Starfleet Command after the Burn.

Excalibur-M 3189 — The *Excalibur*-M in 3189.

In that year, the time-displaced USS Discovery arrived at Federation HQ. Its 2250s-era crew marveled at the futuristic Starfleet ships visible from their ship's viewports. Lieutenant Joann Owosekun marvelled at the design and wondered out loud if this was a new Constitution. She estimated this ship could sleep a crew of one or even two thousand.
