This spaceship has occurred from an asymmetric soup.
This spaceship has occurred from a symmetric soup.
This spaceship is an elementary spaceship.

Notes

  1. ↑ Although neither the first nor the smallest known c/3 spaceships have appeared on Catagolue, the speed as a whole is semi-natural, as on March 4, 2022, a symmetric soup was found containing a dart.[1]
