    5th generation;

    1. Supersonic and improved agility over 4th gen
    2. True multirole
    3. Low frontal RCS and IR signature
    4. Low level of pilot workload (Data-fusion & cockpit layout)
    5. Some form of HMD
    6. Turn-around at 75% of NATO minimum
    7. Datalink
    8. AESA radar

    There I did it, now we know what the definitions means.

    Disagree on “improved agility over 4th gen”; also disagree on 3; it should be Very low not just Low. To me that’s what is separating the 4.5 gen (Eurocanards + SH) and the real 5. gen fighters (F-22 and F-35).

    It is a lof of extra costs and hassle to design an ac that is reducing the RCS significantly; everything has to go inside, you need to use special materials, and there are many other details that also cannot be seen.

    In spite of these costs, all the F-35 partners, Japan, Israel, Russia, India, and China are all on the VLO “5. gen” bandwagon. There must be a reason….

    The reason is probably higher survivability in many different scenarios.

    Anyway if people are having a problem with “5. gen” then we can also use the “VLO fighter” as a term instead…. 😉

    Loke – “If you want a 5-gen fighter in the west there is no alternative” translates into “If you want an F-35…” “Fifth-generation” is a marketing term. Indeed, if you stack the KPPs of a Typhoon, F-22 and JSF side-by-side you may well find that the Typhoon has as much in common with the F-22 as with the JSF. The two LockMart aircraft have a similar LO philosophy and that’s about it.

    I fee you try to confuse the issues here. True, LM have their own definition of things, including 5. gen and supercruise.

    I use the terms according to my own definitions, and that includes “5. gen” and “supercruise”.

    To me 5. gen requires a VLO airframe, that is the most important factor, that makes it difficult for a 4.5 gen a/c like Typhoon to claim the “5. gen” tag.

    The other requirements I put on it, is mainly what 4.5 gen also would need, like AESA radar, IRST, built-in EWS, sensor fusion, improved MMI, etc. So the defining feature is really the strongly reduced RCS in combination with active IR management.

    Loke – I think you may be misreading the piece. It’s not a high-low mix concept. The idea is that the LCC of the F-35 may reach a point where some nations find themselves with un-viably small numbers. They need a more affordable aircraft instead.

    Google translate can sometimes confuse issues. The Danish original text is perhaps a bit clearer (and we Norwegians read Danish just perfectly after being “married” to Denmark for a period of 400 years 😉 )

    However the word complement above should give you a hint. It does say complement and not replace.

    LO, I suggest you read my latest post in the Gripen Info thread — it seems Saab believes their only opening into the F-35 market is to offer the NG as the Lo in a Hi-Lo mix, not as a replacement for F-35.

    F-35 is delayed and the costs are going up, however 2 other major factors are also having a big impact IMHO:

    1. The economical crisis.

    2. Since the USSR collapsed, Europe and Canada don’t see any external threats.

    1. and 2. in combination with the previously mentioned delays and cost increases is naturally giving some food for thought to the partners and other potential buyers. However if you feel you need a 5. gen fighter and you want a western machine then there is IMHO no alternative.

    To me it seems the following countries have either formally committed to buy, or will do it in the not too distant future:

    US (both USAF and USN)
    Canada
    Norway
    Holland
    UK
    Turkey
    Italy
    Australia
    Japan
    Israel

    Not bad for a fighter that is still far from being ready!

    Tribes: It’s Gripen not Grippen 🙂

    After the sale to Switzerland sees Saab brand new market opportunities for the Gripen fighter aircraft. Pressed economy and prospects for very few fighters in the Air Force may be the way in, possibly in addition to F-35, says the Swedish company executives.

    “We market still Gripen as a fighter that can stand alone. That we maintain. But while we can see that a number of partner countries maintain interest in the F-35, but then pushed the economy that they can not get the number of F-35 as they wish. There may well see the Gripen as the cheaper complement to F-35, “says Peter Nilsson.

    This is one of Holland, as the Swedes have in mind. Holland must save more than seven billion dollars on defense in the coming years, but has a desire to buy up to 85 F-35-fighter. There are plans, however, postponed.

    Also Brits have reduced the R-35-purchases – from 140 to perhaps only the 50. In Denmark, politicians are already gone from 48 to now 30 combat aircraft, but the government has proposed further cuts to save money.The number 16 has been reported in the media.

    But the problem for the Defence and the politicians who still want a powerful Danish air force that can be sent out into the world, is that too few planes destroys the ability to participate in international operations, and the limit is approaching, as the number decreases. This is one experience in Austria, who bought 15 Eurofighter Typhoon.

    “I have neither the pilots or flight enough to participate in international missions. It is simply impossible with so few planes and so little personnel, “said the Rupert Stadlhofer, Brigadier General and head of the Austrian air defense forces when ing.dk visited the air base in Zeltweg in July.
    Saab stresses that you have not received official requests to deliver Gripen as a supplement to the F-35, but among others have talked with senior executives in several countries that have aired the idea.

    Interesting… I suggested already a few years back that Norway should consider a Hi-Lo mix of F-35 and Gripen NG. Due to the proximity to Sweden one could imagine basing the Norwegian NG’s in Sweden and outsource almost all operational aspects to the Swedes, with the additional bonus that it would give Norway one extra base (Norway is currently planning to operate all F-35 from one base only (!), most likely Ørlandet, and with a forward base in Bodø for QRA).

    Will they have personell to service and fly such a huge air force?

    Or is this just a way of buying US friendship?

    Tribes: “Flocking to” is not the same as “Have not dumped”.

    Also, those nations signed on at delivery dates, and acquisition and operating costs, that were attractive but not real, and at a point where alternatives appeared equally immature.

    OK, poor choice of words by me… however it does not change the facts; that none of the partners have pulled out, in spite of all the delays and cost increases, and two non-partners have signed on, in spite of the delays and cost increases. To me that says that there is still a strong belief in this program and in the F-35.

    Of course if the delays keep piling up there is a breaking point but I think we are still far away from that.

    BTW Norway is in the process of re-winging several of the old F-16, perhaps anticipating further F-35 delays…?

    Re how many competitions has the JSF lost, better question to ask how many production aircraft are serving with the customers as promised 10 years ago…:)and when they will actually be delivered.

    Winning and delivering are two different things, and the former depends on the latter before it can be counted.

    For sure it is delayed, and price is going up. But still, in spite of that, countries are flocking to the F-35. Does it not make you wonder why?

    It certainly reinforces the idea that Eurofighter gave the JSF a good run for its money in Japan, the Japanese were able to extract every last concession from the winning bidder.

    You lost me there…?

    How many competitions has F-35 lost so far?

    To me, it seems that F-35 is expected to become hugely capable, and that’s why countries are ordering it, in spite of all the delays, increase in cost, etc.

    Unfortunately for the Eurocanards there is a small window of opportunity that is closing rapidly, when the F-35 gets ready the sales of 4.5 gen fighters are going to fall even further…

    Happy New Year

    A Happy New Year to all Rafale fans!

    Loke predicts: In 2012 Rafale will finally get her first export order!

    The question remains though: will it be UAE, India or Brazil? Or two of them? Or all 3?

    Loke predicts: 85% probability that Rafale will win at least one of them! (1 – 0.5*0.5*0.6)

    I’ve two questions about NASAMS and its family:

    1) what are the differences among NASAMS, NASAMS 2 and SLAMRAAM?

    2) and which AMRAAM is the missile of each system?

    P.S.: Happy new year guys 😉

    NASAMS was the previous version, NASAMS 2 is the current version.

    Some of the differences between N and N2 are listed on Wikipedia (link in first post):

    The upgrades consists of:

    • New radars, which can be mounted on a variety of vehicles. The radars have their own power supply and can process and distribute the data independently. The vehicles can be connected via radio links, cable, through Multi Rolle Radio, or through TADKOM.
    • The radars have a larger frequency spectrum and variable rotation speeds, and also an increased capacity to spot and follow targets.
    • Each module can automatically define its position with its northfinder and GPS instruments.
    • The control centre modules can be mounted on a large variety of vehicles
    • The electro-optical MSP500 sensor is equipped with a laser range finder and a TV-camera, as well as an upgraded IR-camera. These can be used to fire the missiles passively, which has been successfully tested

    .

    NASAMS is developed by Norwegian company Kongsberg in collaboration with Raytheon; SLAMRAAM is described thus by Raytheon:

    SLAMRAAM is the U.S. Army’s domestic variant of the NASAMS system.

    Oops, my bad on missing the CLOS info (helps in clouds, but not behind cover)

    According to their own website its range is 20km which is still shorter than an AMRAAM.

    According to some sources a surface launched AMRAAM has a range of 25 km.

    As said before public statements on ranges should be taken with a pinch of salt.

    Dec. 29 (Bloomberg) — India will exceed its unprecedented borrowing target in the year ending March 31 as it attempts to close a budget shortfall amid slowing revenue collections, a finance ministry official said today.

    The ministry will unveil a new calendar for borrowings on Jan. 2, the official said, declining to be identified before a public announcement. The government hasn’t finalized the size of additional borrowings, the official said.

    Indian 10-year benchmark bond yields have jumped the most in Asia after Vietnam, as the government sold more debt to meet its target of keeping the budget gap to 4.6 percent of gross domestic product. The Reserve Bank of India has said the government must rein in borrowings to help check price gains and boost economic growth.

    “The revenue front is not looking good and a pick-up in collections is unlikely this year,” said Prasanna Ananthasubramanian, a Mumbai-based economist at ICICI Securities Primary Dealership Ltd. He expects the budget deficit between 5.5 percent and 6 percent of GDP this year.

    The yield on the 8.79 percent bonds due November 2021 rose six basis points, or 0.05 percentage point, to 8.54 percent at 3:53 p.m. in Mumbai. The rupee declined 0.7 percent to 53.4238 per dollar while the BSE India Sensitive Index, which has lost more than a fifth of its value this year, dropped 1.2 percent.

    The government may borrow an additional 400 billion rupees ($7.5 billion), said N.S. Venkatesh, head of treasury at Mumbai-based IDBI Bank Ltd. He predicts the 10-year bond yield will climb to 8.70 percent if the extra borrowing is as he estimates.

    Stock Slump

    Achieving the goal to lower the government’s revenue shortfall to a four-year low of 4.6 percent by March “will not be easy” as a cooling economy curbs tax collections and state asset sales have stalled due to the fall in the stock markets, the finance ministry said this month. India expanded its annual borrowing program in September by 13 percent to a record 4.7 trillion rupees.

    Will be interesting to see how the slowing economy will impact the MMRCA (if at all!).

    Besides the longer range of the AMRAAM over the RBS23, there is also the issue of networking, Tracking & development.

    Networking: Depending on the model of AMRAAM, pre-launch and post-launch updates can come from a variety of sources (even if LOS from the launching vehicle is lost).

    Tracking: Being a laser guided missile, the RBS23 gives it’s position away as soon as it tries to acquire the target. The missile itself will lose the track of the target goes behind a hill, into a cloud, etc. OTOH, an AMRAAM can be continue to track a target after it maneuvers as stated above.

    How do you know that AMRAAM has a longer range than the BAMSE missile? The Swedes tend to be very secretive about parameters like ranges, and “more than” could mean “much more than”…

    The BAMSE system is not using a laser guided missile it seems:

    The missile used by the RBS 23 system is based on the RBS 70 [3], but unlike its predecessor (which is laser-guided) it is a radar command-to-line-of-sight (CLOS) missile

    These days I think NASAMS 2 with its redundancy and launcher – sensor – command post separation is the better choice. It’s still not mobile, though.

    The latest NASAMS 2 is becoming highly mobile:
