JA37 Mod based on AJS37?

[spacemishka]

Hi there,

 

would it be possible to have a JA37 as MOD of the AJS37? 

 

...P.

Love the idea!

I’d actually prefer a recon variant - with photos we can have passed to our hard drive for analysis later. Might make the recon features of the U/22A a bit more useful too ;)

After watching the video below, I would still prefer this over F-4 (don’t hit me)

I guess if someone could pull it off it would be neat, but I don't see how you would include e.g. the HUD symbology for an a/a gun or radar, or BVR missiles (or whether they could be included in the mod at all), while recycling the assets from the AJS.

From the video, the air frame is a bit longer, the engine and the turn characteristics are better, there is MFD and/or HDD, much more powerful LD/SD A2A radar and (supposing) different HUD display. I am no modder but I think all the above are theoretically doable (ref. JAS-39 mod). Only sparrows is acceptable but the possibility of using AMRAAM would be nice. The only hard part I can think of is the fighter-to-fighter datalink.

The airframe is identical except for the vertical stab as far as I know. The engine was less prone to compressor stalls at high AoA but that's it. Turn performance should be unchanged.

Yep this is correct

 

The question isn't whether the above are doable by a modder taking educated guesses (the A-4 mod had an air to ground radar years ago before the Hornet even, and that was entirely lua based), but whether all those features can be implemented while re-using the FM, systems model, and art of the AJS.

Actually it is a little mor powerful but overall i think there are just parameters to adjusted. Same for the Skyflash,...which is an british Variant of the AIM-7 ( maybe B-version)

There is some work to do...

 

this discusssion seem to come up a little frequent

The Skyflash (and Selenia Aspide) basically started from an AIM-7E and then overhauled most of it. In terms of capability they should be in the ballpark of an AIM-7M iirc.

There’s an good cockpit model from WT 

[streakeagle]

In terms of the 3d model, the JA-37 is dimensionally different, about 10 cm longer.

Skyflash preceded the AIM-7M. It is largely an AIM-7E with an inverse monopulse seeker that is better at look-down shots and far more ECM resistant than the disappointing AIM-7F.

The AIM-7M was the Skyflash inspired upgrade to the AIM-7F: i.e. retrofitted with the US version of an inverse monopulse seeker.

The AIM-7M may or may not have caught up to or surpassed the Skyflash seeker, but it also had the engine/warhead/range/speed of the AIM-7F, which was a tremendous gain over the AIM-7E used as the Skyflash baseline.

I have always wondered why the Skyflash wasn't updated to the AIM-7F/AIM-7M engine baseline.

Dang! I thought there were a mod out there already.

As far as airframe differences go, the JA 37 is as mentioned longer (because the engine has an extra compressor stage), it has different elevon actuators, the drop tank is different, it has a conformal gun pod underneath, and a bunch of data link antennas all over.

 

The hard part though would be the cockpit and avionics; only basic controls are the same as on the AJ 37.

the intakes are also a little different.

All we need now is somebody who are willing to put it into motion.

JA-37 entered service early 1980s, maybe Heatblur will have enough data to make it in the future. They said something about JA-37 sharing the datalink with the early Gripen and this was a big deal, not allowing them to make JA-37, but i don't remember the details.

JA-37 fighters with Skyflash fighting MiG-21/23/29 escorting AJ-37 with bombs or anti-ship missiles attacking Soviet Navy on Baltic Sea would be great.

1971 was the first flight

The topic is about JA-37 (fighter variant), not slightly earlier AJ-37 (strike variant).

Quote

JA-37 first flight was on 27 September 1974, with the first deliveries starting in 1979, serial numbers 37301-37449.

mmmh someone should update Wikipedia

Why? It's all correct. First flight in 1967 and introduction in 1971.

It very clearly states that this is for the AJ (Attack Jakt/attack fighter) variant.

The JA (Jakt Attack/fighter attack) variant was introduced later.

The primary mission is the first letter, the secondary mission the second letter, and so on.

I.e. the AJS featured in DCS had a spaning/reconnaissance mission as well.

Why updating Wikipedia? Wikipedia is correct.

AJ-37 (strike variant, not the one this topic is about) was introduced in 1971. Fighter variant JA-37 (which is the one in the title of this topic) has been delivered to the military in 1979. I don't see the mistake in Wikipedia.

We can all dream! Would love some sort of mod, even if it only added rudimentary Fox 1 capability.
