Default AJ-37 80s payload question

is it true that version AJ-37 of the 80s only loaded aim-9s in the belly?
that means that the most external pylons did not exist in the version AJ-37 of the eighties? because they can only load AIM-9s.

I hope somebody answers me I want to make realistic missions with the payload of the 80s

Yes, the AJ37 only could carry two Sidewinders ...

however, the Viggen version that Heatblur has simulated is the AJS37, which is a modernized version produced (actually, converted from AJ37 airframes) from 1993 to 1996. The AJS has an upgraded computer that allowed more weapon options, such as the Rb15F missile, the BK90 stand-off dispenser, and up to 6 sidewinders.

The outermost wing stations were originally intended for the rb 28 (AIM-4C, an early IR missile) but they were found to cause flutter and fatigue issues and were never used in service. The pylons therefore went unused for most of the aircraft's service life, until the AJS mod came around.

Thank you very much for your response, another question. The RB-15 in which year were already usable by the Viggen? I think it started to be used in the Swedish air force after 86? Or he could only use the AJS already entered in the 90s?

On 1986 the JA37 could carry only the earlier Rb04 missile. The Rb-15f could be carried by the JAS37 starting from 1993.

Initially the Rb15f was destined to be used by the Saab 39 Gripen, but as the Gripen development took longer than anticipated, the swedish air force upgraded the JA37 Viggen as an interim measure.

The Rb15f could also be carried by the armed recce version AJSH 37.

However, the Rb15 actually entered in service earlier, on 1984 with the swedish navy, which used it as a surface-surface missile similar to an Harpoon missile.

Could also mention that the rb24 is to heavy to be carried on the outmost pylons because of stressdamage in the wings and that would significantly reduce the lifetime of the frame. Therefor the outmost pylons was only allowed to be used in times of war.

Well, as missions in DCS are usually meant to be a conflict simulation, the important thing is if the weapon can or cant be mounted ... here is a photo of a AJS37 with the outboard stations armed:

This statement about the stress caused by the outboard Sidewinders always confuses me. In case of war during the 1970s/80s, would it have been possible to mount rb24 on the outboard hardpoints without modifications or not?

No, on that timeframe the Viggen AJ only could mount two sidewinders on its fuselage pylons.

beautiful photo and thanks for your clarifications, basically what I'm looking for is to know what weapon configurations it would take and what an AJ-37 could not carry between 1980 and 1990.

thank you very much
