There appears to be two different ships shown in the trailers (not inclucding the fleet of ships). One ship is Lockdown's night ship and then there's another ship which in one of the trailers, is shaped like a shrimp that flies over the Great Wall of China (sunset behind). Are the two ships the same or different?
Different and that ship us much smaller. It's theorized that it may be lockdowns dropship. The same one that we see lockdown stepping off of with his minions. IMO, I don't think the larger ship can actually land.
