The F104G had a double rail pylon (2xAIM9s) that could be mounted on
the center fuselage station. I don't know if the C had the same
capability. FWIW USAF experimented with a 104A carrying a Genie (MB1)
nuke rocket on an extendable rail hung on a center fuselage station. I
think the problem was lack of precise ranging information for an
accurate launch. (Glad they didn't do it - nukes were always a PITA.)
