Developed in the 2350's with technology from the Galaxy project, the Type 7 was a radical departure in established Starfleet shuttlecraft design. Larger than the commonplace Type 6, it featured a forward entrance ramp between the two viewing windows, more cabin space and far more powerful warp engines.
Originally only intended to be used on Galaxy project-related starships (such as the Nebula, Challenger and New Orleans classes) and brand new stationary installations, it eventually saw limited service in older starships and stations. However its large size and complex construction limited its possible uses, and it was quickly superseded by more practical and easy to deploy shuttle designs.
