Caterpillar

Drake maintains that the Caterpillar, a sprawling, modular spacecraft which appears at least somewhat like its namesake, is for legitimate commerce and extended search and rescue missions... but at the end of the day, the Caterpillar is truly the evil twin of the Starfarer.

Note
Officially, the length of the Caterpillar is 66.5 meters. However, during the 4th Annual Anniversary Livestream, Lead Ship Artist Elwin Bachiller mentioned that the ship is actually longer than the Starfarer. This would make the ship over 100 meters long.
