The E/F is a UAE-specific version, developed for the UAE at their expense, & for which any other buyer would have to pay a royalty to the UAE. Some buyers may prefer not to do that - and perhaps the UAE does not want it sold to some buyers (does anyone know if the UAE has a veto?).Will the Gripen C/D still be sold once the E/F version is avalible? I was just curious since the F-16 C/D is still being sold even though there is a E/F.

Regards,Sweden to Modernize its JAS-39 Gripen Fleet

It has been a good couple of days for Saab. Fresh off a come-from-behind win in Thailand, the firm has signed a SEK 3.9 billion ($600 million) contract with the Swedish Defence Material Administration (FMV) to upgrade 31 Swedish Air Force JAS-39 A/B Gripens to the very latest JAS-39 C/D standard.
The FMV has also given the go ahead for the next-generation 'Gripen Demo' variant, whose development program includes the development of a new Gripen test flying platform and a new Gripen avionics set. FMV Gripen Demo funds in this contract can be added to an earlier SEK 1 billion (currently $150 million) award, as an offset to Saab's participation in the European nEUROn unmanned fighter program.
Gripen Demo will be a heavier aircraft (empty weight adds 300 kg to 8,100 kg, max. takeoff weight rises from 14,000 kg to 16,000 kg) with increased external and internal fuel capacity (internal fuel rises 38%, and…) and an increase from 8 to 10 weapon/fuel pylons. To offset this extra weight, Gripen Demo will use a higher-thrust GE/Volvo F414 engine variant, replacing the GE/Volvo F404 variant in current aircraft and giving the aircraft a 25%-35% power boost. Other improvements include an next-generation AESA radar (probably drawing on Ericsson's "Nora" project), along with improved computing and avionics overall, including satellite communication, Link 16 capability added to the Gripen's existing datalink, and improved electronic warfare via jammer pod integration and other measures. Gripen Demo's corporate participants include Saab, General Electric together with Volvo (F414 engine), Honeywell, Rockwell Collins, APPH, Martin-Baker and Terma.
Gripen Demo is designed to pave the way for future variants (JAS-39 E/F, DK, N et. al.). A next-generation Gripen is critical to the long-term viability and competitiveness of Sweden's fighter fleet, and also to a number of contracts Saab is fighting for abroad. Norway signed a $25 million Letter of Agreement regarding Gripen Demo in April 2007, for instance, as part of the 3-way competition (F-35, JAS-39, Eurofighter) to replace its F-16s.
Wait sec. The next generation Gripen is called "Future Gripen" as a workconcept. The main reason it was developed was to increase the range of the previous Gripens. SAAB came up with three solutions, one being a huge under the belly tank, that could not be dropped but could be removed, another one was CFT like on the F-16. Those solutions were dropped because they would be a negative factor on the planes maneuverability etc. So they went for the 3rd option, move the rear wheels from the body to the wingroots, thus freeing the space where the wheels use to be to more fuel. This solution was the most expensive but it did´nt effect the planes draft, man maneuverability etc.Thank for the replies. So if a nation bought Gripen NG they could choose not to have the extra fuel or weapon pylons? I thought that they would have to buy it with the extra equipment.
Never mind aircraft manufacturers like Saab seems have learnt from their cousin in the automobile cousins keep selling the older platform by upgrading the platform with new accessories. In this case the accessories are weapon systems, avonics etc and make these flying birds more lethal.Will the Gripen C/D still be sold once the E/F version is avalible? I was just curious since the F-16 C/D is still being sold even though there is a E/F.
No, to my knowledge it will be the same basic airframe as before. The new landing gear will be housed in pods outside the wing root, and the new tanks will be there the landing gear is today. If you for some reason don't want the extra fuel and pylons you should be able to keep the old configuration.This means, every nation buying the "future Gripen" does get the extra fuel (it´s a new airframe). And the they get extra weapon pylons (were the old wheels used to sit).
I think this has been posted before, it shows the development costs for Gripen and other fighters.So the Future Gripen will have
- A new engine.
- New avionics; radar; computers; EW suite, different integration of EW.
- A radically different layout of landing gear; very different internal fuel layout: basically a completely new airframe has to be designed.
The story of the Super Hornet over again? This is a completely different aircraft from the Gripen. A new aircraft.
A JAS 41!
What did the JAS 39 cost to develop?
Well, you say it yourself: new engine; new design of airframe; new avionics; etc...I think this has been posted before, it shows the development costs for Gripen and other fighters.

You have to remember that Gripen already has gone through two major redesigns. First the B that meant a lengthened airframe for the second seat, then C/D that had to get a totally new airframe for IFR and higher MTOW.
The new engine will be the F414 that is very well tested on the Super Hornet and has the same outer dimensions as the old engine. The biggest change AFAIK for the new Gripen is a new fuel tank pressurizing system. But the dimensions for the aircraft will be the same, exept for the bulges for the new landing gear. So the comparisation with Super Hornet is not valid IMHO.
I suspect the Gripen figure is optimistic, but I'm sure that it really did cost a great deal less than any of the others. It hasn't had a new engine developed for it, & the cost of improving the F404 must have been a fraction of the cost of developing either the M88 or EJ200. Saab also has a long tradition of very cost-efficient fighter design & development.I think this has been posted before, it shows the development costs for Gripen and other fighters.

I know you danes like to taunt us swedes, but I wont fall for it :Well, you say it yourself: new engine; new design of airframe; new avionics; etc...
Not a new aircraft?

Well, you are well informed of the E/F changes in the Gripen.I know you danes like to taunt us swedes, but I wont fall for it :
If you want to stop playing with words and implying things and instead add something more substancial I'm prepared to discuss.
The reference is to something called Unisys, wich I have to admit I don't know much about. I've seen this posted before and I don't remember it being challenged. If you have better data available I would really appreciate if you would want to share it.Here is the source:
The cost of non-Europe in the
area of security and defence
p. 21.
According to the document, EF and JSF are 10 x more expensive to develop.
How the author arrived at these numbers is unknown.
Didn't challenge the numbers. Just used seeing incomparable entities ending up being compared. Natural suspicion. And what do you get for the x 10 development cost. Certainly not a x 10 aircraft, but then what?The reference is to something called Unisys, wich I have to admit I don't know much about.
