The Type-7 shuttlecraft (also known as the S20-class ) was a Federation Starfleet shuttlecraft type in service from the mid-2350s through the 2370s. Due to their size compared to other shuttlecraft, Type-7 shuttlecraft are used as administrative shuttles and sometimes referred to as personnel shuttles.
