USS Excalibur (NCC-26517)

The USS Excalibur (NCC-26517) was a 24th century Federation starship operated by Starfleet.
In 2368, the Excalibur was put in for repairs at Starbase 234, and much of the ship's crew was reassigned. Later that year, the ship was selected for a mission into Klingon territory. The mission commander, Captain Jean-Luc Picard, selected Commander William T. Riker as the ship's commander. His first officer was Lieutenant Commander Geordi La Forge.
In the mission, the Excalibur joined Picard's fleet which blockaded the Klingon-Romulan border during the Klingon Civil War. The ship was one of twenty-three assembled for the fleet and was one of the seventeen chosen for the tachyon network.

During this, the Excalibur would fall back with feigned engine troubles, taking the and the . In doing so, this would open up a small gap in the detection net for the Romulans to attempt to pass through. As their ships passed through the gap, the Enterprise-D and the would swing around, close the gap, and catch the Romulans in the act.
The plan was foiled when the network was disrupted by a high-energy burst released by the Romulans, the net was no longer effective in a of ten million kilometers around the . Subsequently, Picard ordered the fleet to proceed to Gamma Eridon at maximum warp, where the fleet attempted to reestablish the net before the Romulans got there. ()
In the late 2360s, the Excalibur survived an attack by the Borg during a night shift. Several members of the crew, including Marika Wilkarah, were assimilated in the encounter. ()
