A tiny wedge-shaped Starfleet shuttlepod with seats for two, carried by the Enterprise-D for short trips and first seen as the El-Baz in the second-season episode Time Squared.
The Type 15 shuttlepod is the smallest craft carried by the Enterprise-D in Star Trek: The Next Generation. It seats a pilot and one passenger side by side, has a hatch on each side and is meant for short hops between ships or down to a planet.
It first appears in Time Squared as the El-Baz. Later examples include the Onizuka, in which Data flies to Tau Cygni V in The Ensigns of Command, and the Pike, which Data is piloting when Kivas Fajo fakes his death in The Most Toys. In In Theory Picard flies one ahead of the Enterprise to guide her through a field of dark matter pockets.
The pod was designed for the series so that a complete, full-size craft could be built on a modest budget. It remained in use alongside the larger Type 6 until the end of the series.
