oh you would ask this well i am away from home and my books! i am workin from memory here but recall seein that the navy preferred the centerline due to flying characteriscs and the fact that their airbase could get closer to the fight. the air force usually seems to prefer the 2 wing tanks (740 gal vs 600 gal). however in the early days of LGBs one wing and and the centerline would be carried with a Pave Knife pod on the other wingtank station.
as for the brits, no gunpod before the 80s on F-4K (in RN or RAF service) and mostly brit munitions, GP bomb and RP. on loadout i have seen in photos alot is on the inboard, 2x AIM-9, TER with two Matra pods and one 540 GP bomb. and thats RN! three bags of gas for that loadout. after the jaguar came into service the FG1,FGR2 and F-4J(UK) were all tasked air defense with full load of missles 2 tanks and SUU-23.
and finally, go 4 mavericks (payload vs drag/wieght considerations). pre maverick go CBUs. yer not up armored like a Hog, one pass and get the hell outta Dodge!
hope this helps, thos like i said im not at home so cant double check me facts or photos. good thing its only my short term memory thats messed up!
