need evidence Are Swedish AIM-9Ls under preforming or are American Ls over preforming

[Gunfreak]

I tried to use the Ls on the Viggen for the first time. And I never got close to a front aspect lock. The missile bends far less than the standard Ls and the get easily spoofed by flares. 

This is completely different from the Ls I've used on the F16, F14 etc.

So is there a historical basis for the Swedish missiles being worse?

Or are the default Ls over preforming? 

In the F16 there is very little difference between the Ls and Ms.

No, it’s a bug, currently the Rb-74 cannot lock in frontal aspect. See here :

 

Problem is, ED ( weapons are their responsibility now) doesn’t seem interested in even replying to the report not to mention fixing the bug.

I pinged BN and he replied within 5 minutes!

Yea I saw, he must like you or maybe you have the magic touch 

TOViper pinged him twice in that very thread , in Aug and Oct and both times he times he never replied.

Still , let’s see when and if we get an actual bugfix. But thanks for the heads-up!

How it's even possible that this kind of bug exist for more than 1 update? It's same missile as aim-9L with diffrent painting, maybe temporary solution would be allowing aim-9L to be carried by Viggen, until bug get resolved

Welcome to the world of ED.

I did some own investigation and it turns out that all the sidewinders are from ED. But I also managed to shot RB-74 in front aspect with tone, and it tracked.

They are, but getting tone is harder than in platform that can slave aim-9 to radar, so overall performance in a2a will be worse, as it should be.

Related to this, is there some reason the RB-74 can't be loaded on the outer wing hardpoints?  They can take the RB-24 series only, currently, and it seems odd to leave them without the AIM-9L as an option given how they are apparently ONLY used for AIM-9s?

[PhantomHans]

For me the RB-74 will not track for head-on shots from any pylon.

 

Tested at altitudes between 8,000 and 15,000 feet against MiG-19 and MiG-25.
Works great for rear aspect shots though.

There is a disabled AIM-9M in the Entry file, enabling it gives you an AIM-9M mounted directly to the main hardpoint, without an adapter rail, that will not launch or tone.

 

Is there some reason the AIM-9M is not enabled for the AJS-37, or that the most modern sidewinders can only mount on the inner hardpoints where we want to carry other items?

I find it a little odd that the outboard wing pylons seem to be there exclusively for the AIM-9 missiles, as they don't carry anything else, but they can only use the older models?

All I can say with certainty is that this is reflected in real-life manuals.

I'm unsure what the reason for that is. Speculating though, the RB 74 requires an Argon cooling system for its seeker head, the 24 is uncooled and the 24J uses a peltier-effect cooler, which only requires power. Maybe it's got something to do with that.

Because the AJS 37 never carried it, nor is it a weapon the Swedish air force ever operated.

Seems strange for them to do it like that, and would the 24J have been in service up to the AJS-37 retirement?

 

You may be onto something about the cooling.  Perhaps they couldn't run the lines for the gas to the outer pylons, and couldn't get or didn't have the Navy style pylons that carry small bottles for the missiles.
