SAAB JAS 39E/F Gripen - General discussion

I haven’t looked much inte the in-service versions, just the pre-production and production prototypes. I don’t think i’ve seen any of the Swedish prototypes having the LWS.

There is a Gripen C thread

But to answer your question it’s because gaijin uses the older radar for the Gripen Cs rather than their historical radar like the MK.IV

Maybe SAAB has integrated MWS and LWS into one sensor, or the Brazilian version has something that’s much more compact, and keeping the Gripen E streamlined and with little drag possible. Though without much documentation, can’t confirm if the LWS is part of the sensor or a separate thing itself.

I know the Su-30MKM in Malaysia has LWS sensors from SAAB itself, with the module being the LWS-310, though these were modified on. Probably from SAAB’s IDAS kit.

It’s not about numbers, but the QOL. Currently, the radar outright drops the tracks that fly straight and level, misalignes tracks symbols and beam position, drops then reacquire tracks out of nowhere, as if it has no mem. whatsoever. Sometimes it doesn’t plot track’s vector, just default north orientation, for 5, 10, or more passes, only to drop track altogether.
Something happened in Ninth wave and it hasn’t been the same since.

That sounds more like a bug. You can bug report it here: Gaijin.net // Issues (just search a bit first so that you don’t report something that is already reported and known about)

A guide on how to report bugs can be found here: ([Navigation] Technical Knowledge Base | War Thunder Wiki)

So they can keep ignoring the first report and don’t have to triage another more like.

The sensors used on Gripen E are the Elbit Systems PAWS-2, which only gained LWR capability with newer PAWS-2(HR) version.

Is it two sensors or one combining both functions

Wait the heat is melting my brain haha. I’m muddling up my AAR-47s and PAWS-2’s ahah. PAWS-2(HR) introduces TTI (time to impact) It doesn’t seem any PAWS sensors have a LWR capability.

PAWS-2 is based on the CMWS (AN/AAR-57) which also has no LWR and requires a LWR to be fit separately.

Oh bless, thanks for the info.

Now the real question is, on the Brazilian version, what that extra sensor entails now…

Let me know what you find out. :)

That only applies to PAWS-2 itself. Gripen E has a separate laser-warning system integrated into its EW suite if we are talking about wheter it has it or not. Saab lists MAWS and LWS as separate functions. PAWS-2 therefore does not need built-in LWR capability for Gripen E to detect laser threats as other parts of the EW/DAS can handle this.

Sorry if i am a bit confused as to what we are discussing.
Some good reading for the interested:
success-of-a-true-collaboration.pdf page 23

Yeah I don’t think you’ve followed the conversation, we know Gripen E uses PAWS-2, we’ve confirmed that has no LWR function. And Brazilian Gripen E’s have an additional aperture for the LWR near to the PAWS-2 apertures.

Due to a lack of those additional apertures on Swedish Gripen E, its reasonable to assume there is no LWR on Swedish Gripen E’s and that option wasn’t selected. (this is similar to the LWR on Typhoon which only a limited number of EFT operators selected (Spain, UK, Saudi)).

Fair point. I will try to attend the 100th-anniversary event this summer, so I’ll see whether I can find out anything new about it there.

Take photos of all the little sensors and lenses :)

Better shots of this;

In theory on the Swedish E that second aperture should be missing.

That’s one of the first in service planes delivered to Sweden’s air force.
(why are their heads Infront of the sensor in almost every shot?? 😭)

Edit:
Also interesting to note that the sensor mount on the Brazilian version is more rounded at the front and the Swedish one is more pointed.

Anyone have a chance to fly the 39E post turn/weight nerf?

Stuck at work so can’t try it currently. :(


Can we get gaijin to nerf it again so that it has no reason to be played please snail? Knowing them they’ll probably do it anyways
