A Federation supply ship is a type of starship employed by the United Federation of Planets.
In the 24th century, a variant of the Miranda class served as supply vessels. An example of that variant, the USS Lantree had a nominal crew of 26 and was armed with only "Class 3 defensive" armaments.
In 2367, Paul Hickman's stolen Type-7 shuttlecraft, on a course toward Tarchannen III, was spotted by a Federation supply ship roughly 24 hours before stardate 44664.5. (TNG: "Identity Crisis")
