It should be straightforward enough about Arkbird and SOLG; they belong in space. As for the other two,

XB-10 - It's a bomber with limited AA capabilities.

Sphyrna - I think this one has more than enough capabilities to be called an aerial warship. It's a command craft, an aircraft carrier, and an ECM support craft. Not to mention it's large. I would just roll with an aircraft being called aerial warship if it's shockingly large and XB-10 couldn't fill in that role IMO.
