JAS-39E for Sweden

I made this to help see the differences, there are a lot more than people seem to think:

JAS39C:
Empty weight: 6800kg
Thrust: 8208kgf
TWR: 1.207

JAS39E:
Empty weight: 8000kg
Thrust: 9993kgf
TWR: 1.249

Just empty clean configuration, not accounting for any channel losses (which should be the same for both).

The extra 0.042 TWR won’t feel that significant since you’ll be carrying extra weight in missiles. However its TWR will be less impacted by extra weight overall.
Add 4x aim120 to both, and 39C TWR reduces by 0.105 and 39E TWR reduces by 0.094

JAS39E in dev server has thrust 9490 kgf for now not 9993 kgf

I believe current engine stats in x-ray dont reflect actuals stats of the engine in game

Yeah well every engine in game has some “channel loss”. It’s not something devs strive to be accurate, they just use it to tune the FM until it matches whatever datapoints they have

Some engines have minimal channel loss, like Gripen C, I think some planes like the F15 have over 20% loss (in game)

While i do want to see the in-service skin as the default, it is a relatively boring paintjob IMO.

I hope we see the early E Paintjob

This one

as an unlockable skin and the Prototype paintjob

This one

as a GE one or something.

so that’s mean the engine still bugging ? why it is just 0,04 different too slow for E with 17% engine faster as they said JAS-39E for Sweden - #950 by Necronomica

You will get plain grey and nothing else and you will like it.

F/A-18A/C have negative channel loss or so Im being told

that comparation the E should be 0,1 M faster at least without payload

That’s Game Convention. It’s lower than stated values for every plane in the game.


I asked Interfleet a long time ago

Anyways, FM is not final, still in dev. Developers are still tuning it probably, doesn’t really make much sense to report channel loss

need more test for engine JAS39E I think, that’s kinda same while data say 17% faster

I don’t understand. The 17% comparison was full afterburner. There is also a difference in thrust based on speed.

Also, @JFIESTASR where did you get those numbers and could you compare to the C version?

He is tested fly away without armament in same time

Not sure what point you’re trying to make, I just used IRL stated figures for their thrust and weights
39C is marketed at 80.5kN and 39E at 98kN

Like I said small and super slim jet but idk why with 9490 kgf still slow

The E is heavier and fatter than the C .

I mean it’s pretty fast? Are you comparing to things like the Eurofighter? Those are dual engine beasts, much higher TWR

but 17% faster
