20mm cannon. Centerline pod would also take a fuel tank, or probably a chaff and flare dispenser or anything else mission-necessary. Outboard pylons appear to be fuel. Can also carry luggage compartments for getting pilot's golf clubs to Homestead, or other Florida base with nice weather and golf courses.
F-4E incorporated the cannon in the nose. Made it harder to shoot the nose-gear off.
