SAAF JAS-39C Technical Data and Discussion

Take the min fuel, use fuel tank to its max, on majority of maps its more than enough. At 10 mins, its still beast and you will rarely run into F16 running really low fuel as they cant afford it if they get stuck in fight due to large fuel consumption, even though they increased it on gripen, its still like twice better by feeling compared to F16. + you get absurd ammount of CMs and better acceleration after sharp maneuvers. Its better than all F16s ingame as a package.

Btw, not many modern jets with FBW pull large AoA at speed. They have optimal AoA for best turn and that usually what you get or what will FBW allow so you dont dump everything at once or break the plane as lets say 25° of aoa on F16 doing mach one would result in absurd Gs probably annihilating airframe and avionics.

I’m not asking for 25 degrees of AOA at speed. 8-10 degrees at 0.98 mach is fine. That would be in line with most of top tier. Currently it runs at about half that.

Question: did the devs mention missile load for the new sustained turn? Was your 30m fuel test clean-wing? Just checking.

I don’t think they stated in the bug report, but I assume also clean.

Playing live right now and I’m getting a weird thing sometimes where the nose gets hung up in a horizontal turn. Min fuel (or less) and its getting stuck at 10G sometimes between 1000-950kph. AOA also around 5 degrees.

Btw, on that wrong IRCCM about 9M, over the shoulder launched flares wouldnt be any better as it takes quite some time for pyrotechnic flares to get to temp. They would be long gone from seeker while at temp, esp when all russian CM launchers are placed literally on the ass which is barely in seekers FOV. Tests of first 9Ms which had not so effective IRCCM against soviet “dirty” flares due to slow temp rise shown they were exceptionally great from side aspect and rear aspect. Not so much front and i think it still stops tracking and pushes into the flight trajectory of plane if it detects flares. On top of that missing feature.

In a fact, it seems it works incorrectly in game as of now. Because when it suspends tracking, it continues in its OWN tracjectory, NOT targets trajectory. I saw many times when target flew from left to right and my missile had to pull up towards target and to the side. When it suspended tracking, it continued in flying UP, instead of continuing turning after the target. It knows where to fly before it suspends tracking. It seems its heavily underperforming in this aspect.
In addition, tracking is NOT smooth, it always jumps around when it detects flares, thats wrong as it should fly smoothly based on targets rates, not its own. In a sense, 9M is nerferd to Sh**. + its using filters at the edges of seeker so over shoulder flares at the edge barely picking up temp should be highly ineffective.

ER was way more powerfull before the change. It lost like 1/3? of its booster output.

If they didn’t butcher all soviet FMs and artificially buff the f16/f15 I agree

Gripen has a smaller turn radius. its much better than the F-16C in a knife fight.

It has hundreds upon hundreds of flares as well. This is clearly an exaggeration. I hope you are kidding.

He’s totally kidding, guys.

(and its probably missing 2x BOL rails :D )

Still need to check when would the oscillation normally happen. It’s stated in the FCS document that the lateral stability of the aircraft decreases rapidly between 30° to 45° AOA. And the High AOA recovery control law is engaged above 26° AOA by using sideslip rate (beta-dot) feedback to enhance lateral stability, and killing roll oscillations by centering the pitch command and using all aileron authority for roll damping.

I guess we only got the oscillations but not the damping effect provided by the (non-existent) FCS.

Some acronyms decoded in Fig 1.5.2 Flight test recording of a rapid deceleration
turn with max aft stick command (Bleed Of Turn).

It is apparent that the static stability decreases rapidly from neutral to negative above 10° AOA, as the amount of nose-down canard and elevon deflection start to increase:
max aft stick pull

For the canard and elevon, positive value means trailing edge down, and negative value means leading edge down.

Just so things get cleared up. Found this on the Defyn discord server. I said before the Blk 10 F-16 can beat the gripen especially after the nerf but after seeing this I am not so sure. Keep in mind this is an 800 kph merge and both are holding pitch up, so pilot skill is not a factor here but its also a simplified duel. However this goes to show how good the gripen is, keeping in mind a Blk 10 destroys the F-16C

So it’s definitely the best rate fighter in game now ?? Sounds strange but… ok

İts an advanced delta canard design coming from a nation who mastered delta designs.

İts not so surprised to see that it can beat F-16, remember guys USA doesnt produce best jet fighters in every single category same goes for Russia.

Not surprising its a monster in a one circle fight, delta’s always are.

No, it literally sounds perfectly fine… that thing was accepted into service in late 90s with god damn long development. F16, 15, flanker or 29 are pretty much 1-2 decades older designs. Thats like wondering why is F16 better than F-4.

how so

there are no bol rails in the wingtips, its not a eurofighter ;P

Inboard pylons are possibly missing an extra BOL739/3 which is either a 6 shot flare dispenser like the BOL739/2 or a BOL rail attachment like that of the BOL-304, 500 or 700.

so its got all of its rails, just missing a few single countermeasures…

im more interested in this tbh https://www.saab.com/contentassets/b6dbecc8e8574587b91116a778fcd20a/estl-product-sheet.pdf
