    Unlikely. As B-I-O explained in some detail (and with considerable patience), Lot 12&13 contracts for long lead items are already in place.

    Your problem is that your reading de Briganti’s articles as if they are reality. First off, he states that Italy will not “order” more than the 13 up until Lot 11. In reality, long lead contracts on 12&13 (not sure on 14- edit yes on Lot 14) is already happening. That is 28 aircraft for Italy. He chooses to read into the statement by the defense minister that Italy will not order anymore F-35’s. That statement is deliberately vague because, being new, the minister was unsure of the status of current order book for Italy. The program of record stands at 90 for Italy. That may or may not stand, But Italy is certainly committed on Lots for which contracts already exist.

    The other consideration in that regard is that governments change. The F-35 production schedule runs into the mid-2030’s IIRC. These crucial orders in upcoming lots are stable and run through 2022. New customers can (probably will) be added and others may adjust orders in the future. By 2022, the production run will have already topped any recent fighter program, the cost curve will flatten, maintence and support infrastructure will have been established (meaning that operators will have already invested in non-recurring costs). You think that they will abruptly abandon the program then for another option? Unlikely.

    De Briganti…. no surprise there.

    Defense-Aerospace is the last place to get accurate information on the F-35 program. Basically, every time he posts an editors note on the F-35 it is either: inaccurate, misleading, or an outright fabrication.

    Yet you continue to use him as a reference Haavarla. When are you going to learn?

    F-35 cannon is useless; http://www.janes.com/article/77408/f…-with-accuracy

    Panic! Panic! time to scrap the entire program…. or not. The fix could be as simple as a software patch .

    Personally I am quite dubious it will work as i think that the effort to get to an acceptable tailless configuration would be much more challenging and would take much more time that the one needed to pass from GaAs to GaN AESA

    Fluidic thrust vectoring. BAE being one of (if not) the leaders in developing and testing the technology. The exhaust of next generation propulsion systems will look significantly different from the traditional nozzle. The “nozzle” will be part of the airframe, blended in, likely using FTV technology. This eliminates a major source of drag, the nozzle, also a major RF signature contributor. Designers can better shape the trailing edges and better mask the exhaust gasses.

    The fluidic thrust vectoring can provide flight control in pitch/yaw without having a nozzle mechanically diverting the thrust and subsequent loss of efficiency. TVFC solves the issues with yaw instability of aircraft without vertical stabs at supersonic speeds (hence why flying wings are subsonic).

    Don’t know.
    I thought it was solely developed by the Marconi division of the Selex subsidiary if Leonardo.
    If under British government contract, then the British own the know how.
    I’m not sure if it applies to SAAB.
    Can a company hire a foreign company to do research for their government, and expect it to be their govrnment’sjurisdiction ?

    The short answer is yes, that’s why defense contractors set up subsidiaries. The IP is owned by the party that set the contract. One easy example is the F-16 block 60. UAE paid for development, hence L-M has developed newer blocks that don’t include the same avionics set.

    BAE systems is an independent subsidiary of BAE. In other words, the country of origin of the parent company is largely irrelevant, the intellectual property is usually owned by that nation who contracted the development and not proprietary to the contractors country of origin….unless it includes technology paid for and under control of the parent and company.

    Panzerfeist- While someday it may be feasable for an AAM with an AESA to lock on at such a distance, it may not be desireable. Currently, missiles like AMRAAM go active in endgame, or terminal guidance at a classified but relatively close distance to the target. This assures the target will be within the radar basket of the seeker head and limit time for countermeasures and evasive action.

    A missile that goes active at 40 miles is giving the target ample warning to deploy countermeasures, change aspect, accelerate. Even with the larger NEZ of a ramjet powered AAM, that is nearly a minute warning at a 3,000 mph closure rate.

    From what I’ve read, the main reasons they are looking to switch to AESA seeker heads is ECM resistance, less radome induced boresight error, beam stearing being faster and having better detection and tracking than a conventional array on a gimbal.

    If you want to take a “War is Boring” article quoting Kopp as factual, be my guest. Reality is a bit different and there is no AESA seeker head on any current or projected missile that is able to lock onto a fighter sized target at 40 miles “even on the most agile….targets”.

    One question, radar of Su-57 is it GaaS or GaN? I think GaaS, but i saw in some places talking about GaN, i think only rumours…

    The N036 was stated as GaA, others have speculated that will be changed as the program matures.

    As far as I know, there has been no confirmation of what type MMIC the Himalayas IDAS uses.

    Russian foundry production is just ramping up. I believe they recently announced that something like 20,000 modules had been produced for the N036, which sounds good, but that’s only enough for a dozen or so radars.

    I would take a conservative view on how rapidly GaN MMIC would be introduced, the cost curve has only been coming down in the West in recent years.

    @Rall

    “An F-35 with a Meteor (will be implemented soon) will be the most devilish thing that flies.

    Really Russia need new big updates or new weapons on this area, it is not a surprise new weapons for Su-57. Airplane is important but not less important will be the weapons. All need to be on vanguard. “

    Isnt the K-77M basically like the JNAAMs and isnt the JNAAMs basically a better version than the Meteor because it offers GaN mmics and acts like its own AESA radar?

    “Designers at the Detal bureau, part of the state-owned Tactical Missile Munitions Corporation, added an active electronically-scanned array radar—a so-called “AESA”—to the nose of a long-range R-77 missile to produce the K-77M model. Thanks to its new guidance sensors, the K-77M is way more accurate than other missiles.

    How accurate? Flying 40 miles or more, the K-77M should be able “to maintain lock on even the most agile maneuvering target,” according to one scientist and defense specialist in the Pacific region whose country’s laws prohibit him from speaking on the record about weaponry. In light of the scientist’s expertise, War is Boring agreed not to publish his name”
    d.

    Hmmm, a defense analyst and scientist from the “Pacific region” who speaks in such absolutes, for a publication as esteemed as “War is Boring”……

    I wonder what idea Mr. Kopp is trying to sell now?

    It isn’t about the US really going through with this; there are concerns on both sides. I am not entirely comfortable with the idea of Turkey (in the current climate) getting the F-35. I can also see Turkey’s point of view about making sovereign decisions. The ramifications would be serious for the state of the Turkish airforce and navy if FMS sales are suspended. The US DoD would have to scramble to replace Turkish suppliers on the F-35, and the likely loss of access to Incirlik. It is in the interest of both countries to find a solution.

    I can assure you that Turkey dumping US T-blls and bonds would be irrelevant.

    Congress isn’t just moving to block the F-35 in 2019 NDAA, they want a report on all FMS to Turkey.

    Not to knock aviationist, but are we sure they haven’t? Or do people pay closer attention to sites like flight radar when there is a crisis unfolding. I recall when he posted a track of the RC-135 around the time of the Syria strikes, thing is, that wasn’t all that uncommon for a RC-135 to be flying tracks off the Syrian coast.

    Then again…. there are people who used to sit around listening to shortwaves and police scanners all day.

    B-I-O thanks for those interesting posts.

    Makes me wish they didn’t scrub the fuel flow graphs of sensitive information (mach).

    Think that’s a bit overblown, OPSEC violation. It was flying in Israeli airspace, why turn off transponder? Flew right past Tel Aviv and Haifa, lot of civilian air traffic.

    AIM-120D would have dual pulse engine but it was canceled so 50% better range then latest C versions was probable for dual pulse version.

    No and No. For the love of god,

    If you don’t know the answer, don’t post. Two pages of conjecture: first KGB’s usual B.S., then the usual Marcellogo “I want this to be true so I’l post it”, now this.

    The -120D’s range improvement has to do with the addition of GPS and the two way datalink. More efficient flight path, period.

    We can start a pool on guesses for what that range actually is, because it’s classified, as is Aim-120’s burnout speed and quite a bit else.
