Speaking of inlets…
Here is a picture of the yf-22 inlets:
Here is a picture of the super hornet inlets:
So, no stealth fighters, bombers and UCAVs till this day have canards. You say it’s a coincidence, I say it’s a fact.
You argumententing cum hoc ergo propter hoc. It is as valid argument as:
Every fat person sleeps during the night, therefore you get fat by sleeping.
“Regular line” = Standard su-27
“Dotted line” = RCS reduced
But Gripen NG is not powered by the RM12. The RM12 is a variant of the F404. NG has the F414, in a version with far less Swedish content.
Yes ofcourse, but that does not stop technology from RM12 to be transferred now does it?
There seems to be a consensus that no engine related technology from Gripen can be transferred and my point was only to show that that might not be the whole story.
Well, 60% of RM12 (which powers Gripen A/B/C/D) is Volvo Aero intellectual property, and could possibly be transferred (.. or might not, depending on what deal they have with GM).
It is extremely “heartening” to note that at Bharat Rakshak forums the current Tejas Mk.1 is being repositioned as an equivalent to the Gripen C/D in all respects, like avionics, weapos load, etc..
How about agility?
Instantanoues/Sustained turn rate? What AoA limit does Tejas have? Low speed handling?
And signature? How does it measure in regards to RCS/IR signature?
In a universe called reality..
If you have large facets like the f-117, which scatters diffusely over a very large amount of angles, or use planform alignment which scatters large, but very narrow spikes over a controllet set of angles, which one do you think is easiest detected in a multistatic (networked) radar enviorment?
From my understanding the ir-otis is not in development any more and is in it’s current shape not up to par with for ex PIRATE
I dont know about F414, but in RM12 that powers A/B/C/D quite alot of Volvo Aero intelectual property went into it, like the FADEC, the flame holder, IR reduction techniques like mixing air in the exhaust, bird strike protection etc..
A very good description of changes are available here: (States aroudn 50% of RM12 is Volvo Aero intellectual property, and that RM12 is now completely owned by the swedish state).

UPDATE: So what I meant to say with that is that I guess there are quite some things that could be transferred regarding engine technology.
Could you please translate it ? I found that Swedish to English translators are very very poor on the web..
Rough quick translation 🙂 :
Bofors hopes for new Indian aqusition
Weaponsmanufactor Bofors is hoping for a future sale of weapons to India.
The deal is valued over 14 billion SEK (swedish crowns). As of now a deal has been signed to develop the technical cooperation with India. Karlskoga-Kuriren writes that the eventual order is about a new artillery system.
During the 80ies India bought weapons from Bofors for roughly 8 billion SEK. This lead to the so called Bofors scandal where the company was accused of bribing it’s way to secure the deal, however, the investigation was closed down by the prosecutor.
One day ago BAE Systems Bofors signed a MoU with India about a new artillery system (Archer?), so I kind of fail to see how they could be interpreted as blacklisted.

Wrong don’t mistake IRIS-T for ASRAAM. The IRIS-T seeker is designed by Diehl BGT Defence.
I might be off on this, but I recall SAAB bofors dynamics part in the iris-t project having to do with the seeker as well.
Anyhow, I’m ofcourse cheering for Gripen to take this contract home, but rafale sure is one great plane, imho a notch better than SH.
here is a video by signatory that shows the time for 360 deg turns for a few fighters
Airplanes go to battle in groups, never singly. With NCW sensor sharing, there is no reason for rotating arrays. If there was a need, F-22 would have implemented the side arrays to increase FOV.
Are they scrapped or planned for a block further down the road? I can imagine some cooling issues with side arrays, but if/when implemented that setup should be superior to the swashplate.
F-35 isn’t F-117. There has been significant RCS technology advancement in access panels so they open and close as quickly as non-LO access panels and do not require goop, putty or butter to restore RCS.
Okay, thats what I was thinking as well, but spudmans response seemed to imply otherwhise…
If the radar is tilted upward at all times, only steered horiziontally, it should remain as stealthy a fixed array, no? With the benefit of greater FOV.
As for having to apply stealth coatings on the radome, does that apply to all access panels on f-35 as well?
