Hello I'm new to this system and I have a question about choosing a ships hull. What class do I put the cobra class ship under? Would it be a frigate or raider, or is there a RT supplement that already has them statted up?

Thanks.

Cobras are statted out as NPC vessels in Battlefleet Koronus. They're Raider hulls.

Thank you. I just ordered it and rites of battle for DW.

Cobra are also detailled in Into the Storm, page 152. They are Raiders.
