USS Excalibur (NCC-1664)

The USS Excalibur (NCC-1664) was a Constitution-class Federation heavy cruiser starship in Starfleet service in the 23rd century. The vessel took on the name of a previous vessel, Rollin Bannock's USS Excalibur of several years earlier.


 * The Star Fleet Technical Manual gave the Excalibur a registry number of NCC-1705, however all other subsequent mentions have used the NCC-1664 registry used by FASA's RPG, originally devised by Greg Jein.

Between 2257 and 2265, the Excalibur had two separate encounters with N'shaii satellites orbiting Federation planets. Thanks to the USS Constitution's 2257 N'Shaii encounter, the Excalibur was well prepared to dispatch the menace. (TOS novel: My Brother's Keeper, #2: Constitution)

In 2265, Excalibur began a fourth (and final) five-year mission under the command of Captain Timothy Harris. The following year, the ship was assigned a seven-month patrol of the Romulan Neutral Zone. After this patrol, the Excalibur was allowed a two-week shore leave at Argelius II. (TOS comic: Who's Who in Star Trek #2)

In 2267, the Excalibur was one of the starships assigned to assist the USS Enterprise (NCC-1701) at the inauguration ceremonies on Altair VI. (TOS episode: "Amok Time")


 * While not actually mentioned by name in the episode, an earlier draft of the script that was later turned into a novelization by James Blish included this data.

A few months later, the Excalibur, along with the USS Lexington, responded to a distress call from the Enterprise after it became trapped in the black hole, TNC 65813, following a battle with Colonel Adrik Thorsen and his followers. The Excalibur and the Lexington towed the powerless Enterprise to the nearest Federation starbase on Neural III. (novel: Federation).

In early 2268, the Excalibur was sent to explore sector 221-G, where the vessel discovered a planet that had been home to a Priatian colony. (NF novel: After the Fall)

Later that year, the Excalibur took part in the disastrous M-5 multitronic computer tests. The Excalibur, along with the Lexington, Hood, and Potemkin, participated in war games to test the computer's reflexes while it was installed aboard the Enterprise. The computer went insane, however, and fired full weapons on the Excalibur, reducing the ship to a powerless hulk and killing her entire 400-odd crew. (TOS episode: "The Ultimate Computer")

A second Constitution-class USS Excalibur was commissioned, named in honor of this vessel's sacrifice.
