Yellowstone class

## SPACECRAFT CLASS

The ***Yellowstone*-class** was a type of auxiliary craft developed by Starfleet in the early 25th century.

## History

Envisioned as a successor to the *Danube*-class, the *Yellowstone*-class shared many of its predecessor's systems, but included new developments made in the last decades of the 24th century.

## Technical information

The *Yellowstone*-class runabout was equipped with a standard tractor beam capable of towing other vessels at warp.

The class featured an experimental impulse engine powered by tetryon plasma. Pilots quickly learned that this could be turned into a defensive weapon by releasing the gas from the nacelle vents, producing a cloud of plasma that disrupted the warp drives of other vessels.

## Ships commissioned

It was standard practice to name *Yellowstone*-class vessels for rivers on Federation member worlds.
