Resembling a Bydo more than any other R-craft, this "ship" is more scaled serpent than fighter. The Arvanche was a daring step forward in research for the Space Corps; along with its successor, the B-5A Claw Claw, it tested the tough armored hide of Bydo in combat as applied to Space Corps fighters.


Pilots can unlock this ship by logging in 30 minutes of flight time after obtaining the B-3C Sexy Dynamite.
