Interestingly, the CG model of the Bird of Prey has weapon ports that resemble -- it seems to me, intentionally -- the SeaRAM launchers
on guided missile cruisers. I had forgotten about that myself, but I saw the way the model is represented in both the IDW comic and the Hot Wheels toys and some of the screencaps. The film version doesn't have the radar dome on top, but the same squared off design the right size and shape to be a kind of multi-tube rocket launcher. If the similar design isn't a hint of that particular design intent, I would be VERY surprised.
