The only known Missionary Ship mentioned thus far is the Minor Transgression, which was captained by Shipmistress Chur'R-Yar and made first contact with humanity. It was destroyed during a battle with Sergeants Johnson and Byrne by the Shipmistress, Chur'R-Yar, in an attempt to kill Sgt. Johnson.
The Minor Transgression was described as being shaped like a fishhook, with many segmented compartments and barbed antennae spanning from the prow to the stern engine. The ship had an umbilical that the crew used to board enemy vessels.
