The SRAMs or free fall nukes would be carried in the weapons bay and usually the inboard pylons. Sometimes depending on the mission the outer inboard pylons would carry a nuke, but usually a drop tank. These pylons pivoted with wings as they swept back. There are two more outer pylons that are at a fixed angle to match the first wing sweep possession. On the Alert birds one fuel tank would usually be uploaded to the inboard fixed pylon. The most common configuration was; 2 in the weapons bay, 2 on the inboard pivoting pylons, and a drop tank on the outer pivoting and inner fixed pylon.
