The Yellowstone comes with an advanced Tetryon-Plasma Engine. This engine grants a +32 bonus to your Starship Warp Core Potential. The Tetryon-Plasma can also be ejected behind the Runabout. Any enemy ship that passes through the Tetryon-Plasma cloud will be slowed and may have its engines knocked offline. The Tetryon-Plasma Engine may be used on any small craft or fighter.
Like other Runabouts, the Yellowstone is often used as a tow vehicle. It comes equipped with a Tractor Beam to handle these utilitarian missions.
Items from the Yellowstone Class can only be used on other small craft.
Unlocking this option also unlocks a Yellowstone Class non-combat pet that can be launched from your starship. The pet does not take up a device slot, but does need to be in your inventory to be launched.
