Enterprise-D was a ship that was warp-capable.
Warp-capable was a term used to describe any type of spacecraft that was capable of warp drive or transwarp drive.
Such a spaceship was often referred to as a "starship," and it could have been anything from a shuttlecraft to a dreadnought.
In the 33rd century, when Craft learned that the USS Discovery had a warp-capable shuttle in its' shuttlebay, he realized that his homeworld of Alcor IV was in range. (ST: "Calypso")
