Advice mostly for me given by someone else concerning airships · 11:16am Feb 27th, 2019
We've seen several airships with propellers for power, and that includes the Storm King's airships. We've also seen some Equestrian designs that have no propellers, but have fins, instead (More fish-like, perhaps?).
I don't think we've seen any armaments on an Equestrian airship, and I think the only weapon we saw on the Storm King's ships was the harpoon gun--which from the flash and bang, appears to be a proper cannon.
