Reparem, como ocorreu com a IKL, naquela estória do 209, 214 e 212, onde um gráfico tentava enrolar os coitados dos desavisados. O Gráfico da SAAB induz a pessoa ao erro.

O C/D continuará a ser C/D, porém poderá ser modernizados com parte dos sistemas desenvolvidos no programa NG (novos sistemas como o radar AESA, o novo EW, etc.). A longo prazo parte dos sistemas do C/D serão similares aos da nova versão E/F.
A nova versão (NG ou E/F ou como queiram chamá-la, N, DK, IN, BR, etc.) terá as alterações estruturais, nova turbina e os novos sistemas em testes e ensaios atualmente no desmostrador, o Demo. A nova versão está sendo oferecida a Dinamarca, Brasil e Índia.
Se o cronograma é compatível com o F-X2 ou os riscos aceitáveis ou não vis-a-vis com os benefícios, essa é uma outra história que nunca me atrevi a responder. Mas parece que em fóruns há uma turba que se crê mais capaz que os especialistas em avaliação de aeronaves do Brasil e da Índia.
Segundo a imprensa especializada e a própria Saab, o JAS-39E/F será a nova versão com as modificações estruturais e a nova turbina e não o JAS-39C/D modernizado. Ambos co-existirão.
Saab believes it will sell over 500 of its new-generation JAS 39E/F Gripen fighters, on top of another 200 of its current JAS 39C/D model over the next ten years says Bob Kemp, Senior Vice President for International Sales and Marketing at Gripen International, the company set up to market the Swedish fighter.
The new E/F-model, or Gripen-NG, is at the core of Saab’s longer-term marketing strategy, says Kemp, who explains that customers that require a new fighter post-2015 will be offered that advanced variant.

The Gripen Demonstrator will be used to evaluate the AESA, and in general will pave the way for continuing updates of Flygvapnet Gripens, the ultimate goal being the "JAS 39E/F Gripen NG" with the AESA, F414G engine, more fuel and stores attachments, plus a wide range of other enhancements.

Sweden to Modernize its JAS-39 Gripen Fleet
17-Oct-2007 18:07 EDT
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 7,100 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.

This leaves the air force with 100 fighters, fewer than at any time during or since the Cold War. Sweden will offset the reduction by maintaining the force at a high technical standard. The next step will see all JAS 39C/D fighters modernized to a common configuration known as Materiel Standard (MS) 20, already under contract. Also approved is the integration of a new radar-guided missile, the MBDA Meteor, regarded by Saab as a massive improvement in lethality over the AIM-120C advanced medium-range air-to-air missile.
The next configuration, MS 21, is being defined, but it is clear that MS 21 is in fact the NG, with the General Electric F414G engine; modified airframe; Selex Galileo Raven ES-05 active, electronically scanned array (AESA) radar; Skyward-G infrared search and track (IRST) system; and new core avionics. Selex’s Raven 1000P radar prototype is flying on the Gripen Demo and a ground rig is testing the innovative avionics in which flight-critical functions are partitioned so mission capabilities can be added more quickly through the fighter’s life.
The government is funding development of the definitive NG, which the independent defense procurement agency FMV calls JAS 39E/F. (A contract for the avionics system was issued in May.) The production version will have a larger wingspan and area, and the landing gear will be fully integrated with the wing (on the Demo, gear loads are taken through the wing and fuselage). Maximum takeoff weight has been increased (compared with earlier NG proposals) by 1,100 lb. to 36,400 lb.
