TTR seawolf platform for UUV

Hello,
I have one of this submarines (http://www.ttrobotix.com/products/list/263.html) and I want to use ardupilot to make it autonomous, but I cannot find this frame in the configuration. Please, anyone could advice me?
Thanks!

Ardusub is part of Ardupilot but at this time QGroundControl is the GCS of choice.
