Slenke:
A few years ago SAAB did a study on a RCS reduced Gripen. Redesigned divertless air-intakes, pylons, new canards and wing (for canard and wing edge alignment).

What do you expect them to do? Put out a press briefing stating they have are on par with NG’s offerings?
Nonetheless, if we assume they do not offer LPI modes on APG-79, it’s by choice (perhaps export restrictions or what not) and not lack of capability.

Geez. Give a handful of half-decent students a master thesis project to research and implement LPI algorithms for ESA radars and you would be surprised.

The foundations for LPI radars has been in the public domain for decades, it’s just until recently using digital recievers they can be counteracted (and yes, that includes APG-77.)

That particular picture is a photoshop. It shows a BAE Replica style aircraft at the Qinetiq facility in Boscombe Down, when the actual BAE Replica had the work done at BAE in Warton, Lancashire! There is only one known picture of BAE Replica, upside down in a hangar, in quite low resolution from the New Scientist magazine.

I really don’t see why it is impossible that QinetiQ was doing RCS pole testing at their facility, even though said aircraft was produced at another. Happens all the time in the rest of the world.

The chanche that Sweden will fund a new fighter programme in a forseeable future on it’s own is zero, zilch, zip, nada.

How can one verify it mathematically without knowing the correct RCS of the F35 ?

You can get a *very decent* ballpark figure by modeling the aircraft. And that is using open source intelligence.

Nope, sorry. Only have rumours.. And like I said I wouldn’t value them all too high.. 🙂

Neat looking machine, if it will be proceeded with. My immediate question is, what engine in the 170KN class will power this aircraft ? Will it be just like the long series of SAAB fighters , a licensed foreign engine adapted/ improved as needed, and if so, which one?

The chanche that it will ever be built are slim, but Volvo Aero did research on a heavily modified RM12 engine as a part of FS2020 R&D program.

FS2020 has been replaced with a new program called Flygsystem 2025 (FS2025) which is recieiving active funding from the defense research agency (FOI) and if the buzz is to be beilieved, is an aircraft design that is radically different from FS2020.
