I don't usually trust these cutouts
but it makes sense to me that gunner control on the side of the ship would be able to track a pod fired out of the bottom of the ship if that is a view screen and not a window (as the scale seems to suggest).
Even so the room may be orientated to dip down (artificial gravity and all) so it could still be a window on the bottom of the hull (it's not very clear in the shot).
I don't think it's a bridge.
It seems to have little periscope style targeting scopes and the like.
It seems to be a specialised gunner control room and I imagine there may be many on a ship of that size.
