Gaijin expand JAS39 Gripen C (SAAF) to 12.7 BR in all mode. but wonder might considered infrared Air-to-Air Missile (50G ~ 65G) with IRCCM replace AIM-9M & Skyflash (Rb.71) after this month ?

Honestly, I’d hope/think not for the sake of the Game. R-73s and Nine Mikes are pretty powerful as is, i’d much rather more decompression and more powerful airframes rather than better weapons getting slung around. I don’t disagree that Skyflash is a bit… garbage for 12.7 but equally the only other thing they could add is AMRAAM, and I really don’t want to see that or equivalents yet.

The gripen is already the best plane in the game right now by a pretty wide margin, it doesn’t need any help.

Depends what others get i except the one coming to Sweden next to have AMRAAMS

If they add that then they must add aim9x as counter which I’m sure you would not like

I think he know if they add IRIS-T other nations equivalent will follow

Do have to agree. As far as A/G goes it looks pretty good going, and A/A it is a monster in everything but BVR. To which the correct response is “Get low”

Something with a bit more reach than Skyflash would be nice but if I’m honest I don’t think it needs it. It holds most of the advantages over something like an Su-27 or F-15 in CQC.

I expect gajin not forget change targeting pod to Rafael Litening III for JAS39C Gripen the first major update

Swedish Gripen C armed Rb.99 (AIM-120B) and Gripen C from Czech Republic, Hungarian & RTAF fired AIM-120C-5 AMRAAM except SAAF JAS39C Gripen

it will always have a problem in the amraam meta because it only carries 4…

Look guys proof that the Gripen has upwards of 90-100° of instantaneous AOA!!!

gaijin fix

Looks like the original FM from the dev server, god lord that was fun.

Is there any info on the development of the gripen and the use of computers to aid the overall design vs aircraft like the Mirage 2000 and F-16? It seems like it would be reasonable that the gripen has overall superior airframe performance over the mirage and F-16 since the airframe is much more modern. Maybe more modern computing makes the delta canard configuration possible to develop, resulting in the gripen, rafale, and eurofighter but sacrificing stealth.

There might be information about how it was developed in their books that they publish. You’d have to ask someone like @blockhaj

From what I read in Saab’s JAS 39 design history documentation they did not seem to compare it to the F-16 or other designs, only to their own in-house design options which included a conventional non-canard-delta type design. Sustained turn rate and other factors didn’t seem to be very important to them. Not as much as instant turn rate, short takeoffs, etc. They were also concerned with cost.

A lot of cost-cutting measures and simplifications were made to the design such as using an already available engine (The F/A-18’s)… and it being so small to fit their requirements.

It should be noted that canard-delta design doesn’t sacrifice stealth. That’s simply untrue in a lot of respects. With the exception of the KF-21 Boramae the Rafale is presumably the lowest RCS 4th generation fighter in the world and the latest block of F/A-18E/F comes a close third behind those two.

The introduction of fly-by-wire flight technologies allowed the use of a negative static stability which solved many issues with delta aircraft. The canard, which can deflect to create large down or upward movements (and also reduce the forward lift to make the aircraft statically stable all of a sudden), is what made the configuration attractive. It prevents the issue of deep stall as with the F-16 which does not have sufficiently large elevators to avoid deep stall. Tailed designs also exacerbate the issue in this case because losing the lift from the elevators to force pitch-down actually creates higher instability margin whereas canard has the opposite effect. Larger elevators with sufficient torquing motion are required such as on the Su-27, F-35, etc.

The canard-delta design allows them to save size, weight, make an airframe that lasts longer without sacrificing too much in the way of performance (albeit depending on what metric we are discussing)… While it is a cost-cutting measure, or done simply to meet size and weight restrictions. Meanwhile, the “heavy fighters” of the world continue to dominate. They’re useful for their specific purposes but stealth aircraft are quickly taking over as costs to procure them are coming down.

Since stealth is of more importance than flight performance (in regards to maneuverability) we are seeing more and more designs focusing less on dogfight performance. Top speed, acceleration, etc are important… stealth is also important. We are seeing designs such as the Chengdu J-20 appear which benefit from cost, weight savings, etc as I said… but introduce stealth as a primary design feature.

On the other hand, radar is getting more and more powerful, and if I remember correctly there is a german company that claims it can reliably track an F-22 and F-35 at far BVR ranges. That’s a ground based system though so Stealth can still make a big difference in A2A engagements without ground cover.

I wonder if Stealth will lose it’s value once radars can reliably track them from within an aircrafts airframe, and then I wonder what the focus will be set on next.

That’s part of the reason why I think electronic warfare is the way to go, getting better at jamming and disturbing enemy radars.

Not to say stealth fighters like F22/F35 can’t do that too

Sure they can do that, too.

But in my opinion stealth limits the design of an aircraft and usually has a negative impact on performance and combat roles. Reducing RCS is one thing, but making a plane stealth is usually really restrictive. So unless there is an easy way to build something aerodynamically efficient while keeping stealth it’s always going to have drawbacks.

Is some speculation that the new radar being fitted to the RAF typhoons currently might be able to track F22s. At least at a reasonable distance. But not much info available
