    Contract value is not known however 24ore indicate 7-8 billion Euros for the 28 Typhoons to Kuwait:

    http://www.ilsole24ore.com/art/impresa-e-territori/2016-04-05/finmeccanica-firma-maxicontratto-la-fornitura-28-eurofighter-typhoon-kuwait-143623.shtml?uuid=AC8VjW1C

    If it’s 7 billion then that’s 250 million Euros per a/c.

    Edit:

    The contract also covers logistics and operational support, plus training of Kuwaiti air force flight and ground crews in conjunction with the Italian air force, which also operates the type. Ground-based infrastructure required for the Typhoon will also be installed in Kuwait.

    Naughty…

    This gives roughly two more years of work to the production line.

    Eurofighter confirms:
    https://www.eurofighter.com/news-and-events/2016/04/kuwait-signs-contract-for-the-delivery-of-28-eurofighter-typhoons

    Typhoon is currently in service at 22 operational units and up to now, the whole fleet has completed more than 330,000 flying hours worldwide.

    Not bad — Gripen has logged 230,000 flight hours:

    http://www.gkn.com/media/News/Pages/GKN-Aerospace-to-continue-support-for-Gripen%E2%80%99s-RM12-engine.aspx

    Of course this pales compared to the SH: more than 3 million flight hours!

    BTW, GKN aerospace does the product support, maintenance, repair, etc. not Volvo- http://www.airforce-technology.com/news/newsswedish-fmv-contracts-gkn-aerospace-for-gripens-rm12-engine-4827270

    GKN Aerospace bought Volvo Aero, so I think it’s still the same people working on the RM12.

    According to some sources the international press, Vietnam has expressed interest in aircraft Gripen E / F to replace the interceptor MiG-21 retirement. However, the price is a huge barrier.

    Kalman said that the F-35 is “better than other planes on the market and costs less than some of the other planes on the market. The plane’s cost is decreasing and its maintenance concept will be inexpensive, and become less expensive over time.”

    Its software is “a leap” beyond that of other current jet fighters, he stated.

    While media reports have said the F-35 is fault-ridden and a bad buy, Kalman said: “I read things that have a weak connection to reality. The project entails challenges and risks but I feel full confidence that the stealth jet will take the IAF a step forward… With the jet, the advantage of the IDF and IAF will grow without a doubt.”

    The IAF seems to be very positive regarding the F-35.

    Would not solve anything as RM12 is based on GE F404.
    http://www.geaviation.com/engines/docs/military/datasheet-RM12.pdf

    The only viable ITAR free alternative would be Eurojet EJ200 or advanced development of SNECMA M88 with increased thrust..

    They looked at the EJ200 and decided against it — probably too expensive and did not offer enough advantages for the increased cost.

    Saab showed an GaN AESA fighter radar (prototype?) in Korea l last year:

    Saab says it is ready for volume production of a fighter radar using gallium-nitride (GaN) technology in an active, electronically scanned array (AESA). The Swedish company appears to be far ahead of competitors, none of which is known to have brought a GaN fighter radar to the same level of maturity. Saab displayed a model of the X-band radar’s antenna at the Seoul ADEX aerospace and defense show in October, promoting the system for South Korea’s proposed KF-X fighter.

    http://aviationweek.com/defense/saab-says-it-ready-produce-gan-radar-sensor

    I am a bit surprised they still decided to go ahead with the Selex radar for Gripen E — but perhaps the GaN fighter radar developed in-house would simply not be ready by the time? It seems it takes very long time to develop AESA radars.

    Perhaps future Gripen E/F customers can choose between the Saab GaN radar and the Selex/Saab radar?

    I am sorry but with Frontal optronic removed, MICA missile acting as IR sensors and a radar praised for being stackabe (hence cooperating with the signal processor via a protocol instead of sharing a commun sources of raw data), there are no more fusion in a today Rafale than what can be achieved with Spectra (and TV).

    This has been discussed ad-nauseum. Fusion is not what makes a display decluttered. It’s a multi-variable spectrum identifiable as a singular source.

    Is the FSO “removed”? AFAIK it’s only the IR sensor in the front that is not active in the FSO, and the reason being that the MICA IR sensor is already quite good. What does “stackabe” mean?

    In the Swiss eval the sensors of the Rafale were praised, in particular the old radar; since the new AESA radar has much longer range than the old one, I don’t see the problems with the Rafale sensors that you refer to. Also interestingly the Swiss eval praised the Rafale sensor fusion but found the Typhoon and Gripen (C/D) sensor fusion lacking.

    What do you mean by “there are no more fusion in a today Rafale than what can be achieved with Spectra (and TV)”? As it said in the text I quoted, data from the radar, the IR sensor, SPECTRA, the IFF, the FSO, and the data link are fused.

    Displaying only the best track of the correlated ones, identity fusion two name two examples.

    What does the part in bold mean?

    Then the Rafale doesn’t fit in this “4.5 gen” category.

    It hinges on the computing power of the MDPU to process data from the RBE2-AESA radar, the “Front Sector Optronic” (FSO) system, the SPECTRA EW system, the IFF, the MICA infrared seekers, and the data link.

    1 – “Multi-sensor data fusion”

    Implementation of the “multi-sensor data fusion” into the RAFALE translates into accurate, reliable and strong tracks, uncluttered displays, reduced pilot workload, quicker pilot response, and eventually into increased situational awareness.

    It is a full automated process carried out in three steps:

    1. Establishing consolidated track files and refining primary information provided by the sensors,
    2. Overcoming individual sensor limitations related to wavelength / frequency, field of regard, angular and distance resolution, etc, by sharing track information received from all the sensors,
    3. Assessing the confidence level of consolidated tracks, suppressing redundant track symbols and decluttering the displays

    How is this different from slide 5: http://www.slideshare.net/robbinlaird/combat-systems-fusion-engine-for-the-f35

    Below a link to slides explaining about “sensor fusion” in the F-35.

    http://www.slideshare.net/robbinlaird/combat-systems-fusion-engine-for-the-f35

    Slide 5 shows how “4.5 gen” a/c like Rafale, Typhoon (and Gripen?) do”sensor fusion”; slide 6 shows how it’s done in the F-35.

    Slide 11 explains the difference between “4.5 gen sensor fusion” and “5 gen sensor fusion”.

    Speaking at the FIDAE Airshow, company official Haim J (Rafael requested that his surname is not disclosed for security reasons) said that integration of the Smart Precise Impact Cost Effective (SPICE)-series of precision-guided munitions (PGMs) should begin before the end of the year, ahead of its planned completion date in 2020.

    According to Haim J, with Rafael’s Litening and RecceLite targeting pods and SkyShield electronic warfare system already integrated onto the Gripen, the company will be working to fit its SPICE 2000, SPICE 1000, and SPICE 250 PGMs in accordance with its contract with Saab.

    Saab signed its USD245 million weapons integration contract for the Gripen E/F with the Brazilian government in April 2015. Besides the Rafael systems, the proposed weapons fit for the 36 aircraft currently under contract includes the Denel-Avibras-Mectron A-Darter short-range air-to-air missile and the Diehl BGT Defence IRIS-T short-range air-to-air missile.

    Gripen E/F will have quite an impressive number of munitions and pods integrated. I didn’t know the Skyshield jammer pod already was integrated on the Gripen!?

    The Swedish Air Force (Flygvapnet) is putting new life into a war-time strategy developed during the Cold War: fighter jet operations from road strips. There is a difference: the armed forces have got to do the same job with less personnel.

    The redefined concept will see the Gripen serviced, (re)armed and (re)fueled by 6 personnel on a forward operating location, using only two modified vans with equipment per jet plus a fuel truck travelling between several aircraft and a fuel depot.

    Basically what you’re saying is that further orders for the Gripen E will have a lower unit cost. Maybe so. Then again, this doesn’t help prove that the Gripen is significantly cheaper than the F-16V/SH. Not unless you know what proportion of its bids were earmarked for reimbursing R&D expenses.

    In fact, its quite possible that the R&D costs were not passed on to the customer, to help maintain cost competitiveness; better to make a modest profit by winning a contract, rather losing the contract after shooting for a higher margin. The Swedish govt too might have preferred to retain jobs and improve economies of scale, over recouping part of its investment.

    The best way to compare costs is to compare within the same competition.

    For some reason Gripen has hardly ever faced the F-16V in a competition. The SH it has faced several times however. One of the few datapoints we have is from Brazil:

    Defense Minister Celso Amorim and Gen. Juniti Saito, the air force’s chief of staff, said at a press conference after the official announcement that the planes will be delivered in 4 years. The total cost of the deal will be $4.5 billion.

    According to figures previously reported in the Brazilian press, the overall deal offered by the French was around $10 billion including maintenance, while Boeing proposed $7.5 billion.

    http://www.ibtimes.com/president-dilma-rousseff-announces-brazil-buying-swedens-saab-gripen-jet-fighters-1514060

    Perhaps if SH had been chosen the Brazilians would have succeeded in reducing the original 7.5billion price tag; but by how much? I strongly doubt they would be able to get anywhere near the Gripen price tag.

    The operating costs for Gripen NG will also be significantly lower than for the SH. Operating costs is often forgotten in discussions like this.
