Options top to bottom:
-16 x 120 kg bombs + droptank, OR 16 x flarebombs + droptank
-3 x Rb 04 ASM. This was a transport mode, since the one fitted to the central pylon couldn't be fired. (Could also have been a planned option)
-1 Rb 04 in transport mode + ECM and flare/chaff pod
-2 Rb 04 + droptank
-2 Rb 75 Maverick on wingpylons
-2 Rb 75 on inner pylons
-2 Rb 05 AGM, rough equivalent of AGM-12 Bullpup + Countermeasures
-2 Rb 05, CMs, droptank
-2 Rb 05, 2 gunpods, droptank
-2 Rb 05, gunpods
-2 Rb 05
-2 6x135mm rocket pods, CMs
-2 rocketpods, droptank
-4 rocketpods
-2 gunpods
-2 gunpods, droptank
-2 Rb24/Rb24J Sidewinders, droptank
-2 sidewinders, 2 gunpods
-2 sidewinders
Computerpower and wiring are the biggest limiters regarding number of weapons carried at one time. More could be hung of course, but it couldn't be fired.
There has also been some surprise at forums over some of these options as some of them simply weren't used. (mounting on different pylons for no apparant reason)
The droptank was used as often as possible (always during peace) and was really considered an extra tank, only to be dropped in emergencies.
