Using the RB-75 aft the 15's

[Capn kamikaze]

After I used the RB-15's on a pair of ships, I had a pair of RB-75's which I planned to use on the last one in the convoy, however the tv screen refused to come on no matter what I did, I can use the RB-75 on its own, I know how it works, but it seems after using the 15's it doesn't want to play.

 

Anyone else run into this?

You generally cant mix air-ground weapons.

 

there are only 2 exceptions.

 

RB 05 + Gunpods work.

And RB 75 + Gunpods work.

 

but those are the only air-ground mixes that are valid.

(This is as it should be)

all loadouts are ofc allowed together with air-air missiles but those 2 are the only valid air-ground mixes.

 

When you load a invalid loadout one of the weapon types in question wont work.

Why's that?

It's just the way that the Viggen was designed.

Fair enough.

It's just the way that the Viggen was designed.

 

Meaning the viggens weapon computer is not designed for mixed loadouts (except the two mentioned exceptions).

[mattebubben]

The Viggen has an Armaments panel oustide of the aircraft that is set to the correct position for each loadout as a part of the arming procedure.

 

(Here is an example of those pages of the manual concerning that armaments panel) http://imgur.com/a/xrc6o .

 

So for weapons to work in the Viggen you need both the outside weapons selector to be in the correct position

(to tell the aircraft what weapons are on the pylons) and the in cockpit selector to be in the correct position

(To select the weapon/mode of release)

 

And we need to consider again that the Attack Viggen is designed primarily for 1 pass type attacks so multiple weapon types are not that optimal since that would require atleast 2 passes on the target.

 

If there had been export customers its possible their aircraft would have been configured differently but for the Swedish airforce the mixing of loadouts was not really needed so its not something the aircraft is set up for. (Except for the already mentioned Guided missile / Gunpod combo)

.... so multiple weapon types are not that optimal since that would require atleast 2 passes on the target.

 

That's not entirely true if the first weapons fired are stand off weapons like the RB-15 is, it would be quite reasonable to fire those off, then approach and use shorter ranged weapons on soft targets.

 

It doesn't really matter though since if as you said it simply can't do it, or should I say couldn't do it, then fair enough.
