Shuttlecraft

In starship classification, shuttlecraft, or shuttles, are auxiliary craft typically attached to a starship or a starbase. Most shuttles are short-range vessels, possessing only impulse drive or limited warp capability. Utilization of shuttlecraft is common for most spacefaring civilizations, especially for situations where the transporter cannot be used for landings, or where such technology does not yet exist.

Shuttlecraft range in size from the larger, longer-range, and more versatile type of shuttle, known as a runabout, to the small and short-range type of shuttle, known as a shuttlepod. All Starfleet shuttlecraft from the 23rd century onward had warp nacelles indicating warp capability.
