How many jamming pods is the growler to carry? looking at this picture(see below) it looks like a total of 5, which would leave 2 hardpoints open for self defense weapons. If conformal tanks could be added, the drop tanks could be taken off freeing up an extra two harpoints for some sparrows or something(if the airframe could handle it). The growler is not going to be able to drop its jamming pods, so I wonder if the crew would rather have an extra two missles, with a little exrtra weight added to an already heavily weighted plane, as opposed to only two.
