The airframes will be new builds. But parts that can be scavenged, for instance the ejection seats, will be reused.
Metamaterials are potentially as effective as LO-shaping, unfortunately currently extremely narrowband, but given the current pace of advancements it’s not inconviebable in the near term (well, relative, who knows, a decade or so?) “shape, shape, shape, materials” will become “materials”.

So the official F-35 order cut is coming. The US Navy will be glad to just dump the F-35C and buy Silent Hornets instead.
Those cuts are a result of the automatic spending cuts triggered if the US debt ceiling is reached. They will probably make sure that does not happen.
But further along the road, F-35 cuts are likely.
There is no such thing as ‘IR stealth’, certainly not for an airplane that is supersonic. For subsonic flights low emissivity coatings and means to lower the signature of the exhaust reduces signature, but it not on the level which can be called stealthy.
FYI, ATD-X Shinshin was RCS measured in France, because only the US ad France had such RCS measuring facilities.
Here is a shot of Viggen from the 90ies, on its way up from the underground for RCS tests on Combtech’s (a SAAB subsidiary) outdoor antenna measurement range.

No problem! Easy thing to get mixed up. Thanks for reporting from the stream.
Signatory, the oracle of all things Gripen, seems to indicate May 2013 for resumed flights with Gripen Demo, no info on the first flight of a newbuilt aircraft though.
“Return to flight of #Gripen test aircraft 39-7 scheduled for May 2013 (Phase 5) fitted with digital HUD, 4 channel AESA, IRST.”
“#Gripen E flight test programme using a/c 39-7 (existing NG Demo) and future airframes 39-8, 39-9, 39-10.”
May 2013 is interesting! Last I heard it was as scheduled to fly in late 2013 (December IIRC?). Curious to the see if the rumoured external changes hold any water.
Syarikat means compay, Daesu = Dassault 😉 Creative spelling.
Gripen does not have any classified features. It has the engine that is flying in superhornet for decades. so the power supply for various systems is known. and second it has obsolete aerodynamics beloning to 1980s. More likely comparable to Lavi/J-10. that belong to pre supercomputer era.
I never heared SAAB installing new supercomputers or buying Japanese industrial robots.
Sweden simply dont have any surplus money or technical power. even if it knows anything it cannot implement effective counter measures. as most of R&D in Sweden is for benefit of foreign multinationals. so there is no control over R&D to create unique un saleble product on vast scale.You need alot of money and bargaining power to trade intellegence in 21st century. Sweden has none. maybe 20 to 30 years ago when it has niche capabilities in R&D. first thing is you start with supercomputers for design.

Ok! 😮
Hum a few navies have and even more are now building stealth frigates. The fact that the US stayed way behind for a while and is planning a doing so in the future with the prologation of current class of ships doesn’t mean the rest of the world is. China, Russia, India, Europe… many countries are building stealth ships.
Also while most people talk about the Visby class when thinking about steatlh ships, the very first were the French Lafayette class.
9/10 of those stealth sthips are arguably not stealthy but rather have reduced observability characteristics. Most (all?) of them have exposed weapons. Many sensors/antennas are not sufficenctly dealt with (lack of lo&bandpass-radomes for radar is not an uncommon sight for ex). Visby is one rare exception.
Anyway, that is for another topic and not the F-35 thread…
Aha… I mis(?)interpreted the text as if SAAB was chosen as a partner for the KF-X project. If so I thought there would be some kind of annoucment. I guess they where only discussing one of the proposals going forward for KF-X.
[…]
Some news.
– Saab was the foreign partner that was involved in the project under the radar.
– The KFX has a Saab-certified life-lime cost(Development + Production + Operation) of $23 billion for 120 Block 1 units.

Interesting.
Do you, or anyone else reading this thread, have another source for that? (I.e. a source that is not a forum posting / blog post)
The amibition (in terms of RCS) of most ‘stealth’ ships are far far far lower than what is deemed stealthy on an aircraft. Most of them only do the bare-minimum, reducing the specular return from the superstructure, but little else.
Gripen E/F will not necessairly use MAW300. As an alternative SAAB has proposed a two-color IR MAWS solution. I have not heard much about that lately though.
See this http://bayimg.com/MaiCaAAem for some older (~2008-2009 IIRC) information.
