NCC-7100 was the registry number on a model of a Federation Template:ShipClass star cruiser.
The model appeared in Captain Jean-Luc Picard's ready room aboard the USS Enterprise-D throughout its lifetime (TNG: "Encounter at Farpoint"; Star Trek Generations), although it was briefly replaced by that of a refit Template:ShipClass heavy cruiser at various points in 2364. (TNG: "The Battle", "Hide and Q", "Too Short a Season", "The Big Goodbye")
