    Since you only need to get the AIM-120 “close enough” for it’s active seeker to find the target, the AN/ALR-94 (and by extension the ASQ-239 ) are more than capable of doing this, especially considering the automatic datalinks & triangulation that they provide.

    How is that not true ? A lower profile will have a lower RCS. To use an extreme example, are you saying that a stealth F 35 will have a lower RCS than a non stealth F 15 remote control replica ? The replica will have a lower RCS

    Compare two aircraft of relatively the same size, the F-16 and F-35.

    The F-16 was designed with a “sleek efficient design” and the F-35, not so much (length-to-width ratio, internal bays, internal fuel, etc).

    However, the F-35 has a MUCh lower RCS due to the care taken in designing it’s shape & materials to control radar energy.

    In my examples of the T-50 and J-21, they would have to do a better job of shaping than the F-35 and use much better materials in order to overcome the inherent RCS penalty of a larger airframe. Given that this is their first at bat with tactical fighter stealth, that simply won’t happen.

    UCAVs are not coming any time soon that will compete with manned fighters, especially in the A2A arena.

    The reason is simple, they all rely on constant datalinks for the most basic of operations. Screw with their datalinks or just don’t have the coverage or bandwidth and you are screwed. The only answer to that is AI pilots and that is a LONG way off.

    Btw, you need to research the F-35 vs traditional avionics packages before saying something like it’s easier to do “x” in the Rafale vs the F-35. Things like a software defined radio, middleware, modular/open architecture, UIA and a MASSIVE userbase gives the F-35 advantages that just don’t exist in other programs yet.

    Then there is the whole Rafale is already more expensive now and will only get worse as the F-35 gets cheaper.

    This just in from India… The Rafale is at least $6 mil more expensive than the F-35A (Full Flyaway Cost comparison).

    India will pay 3.42 Billion Euro for 36 planes ($106mil each) while the F-35A is $99mil in the same timeframe. The proposed F-35 BlockBuy is not included in this comparison but would save an additional $3-$4 million per plane if executed.

    http://www.tribuneindia.com/news/nation/rafale-will-bridge-two-decade-gap-and-tech-divide/298655.html

    The negotiations ended at a price of 7.898 billion euros, sources in the Ministry of Defence said. Of this, 3.42 billion euros is the cost of the bare planes; 1.8 billion euros is associate supplies for the infrastructure and support; 1.7 billion euros is India-specific changes to the plane; 710 million euros is the additional weapons package and 353 million euros is the cost of ‘Performance-based Logistics Support’.

    sound logic

    You could say the same of the US B-2 force as there are probably less than 40 pilots in that program.

    Besides, there will always be F-35s on the carriers or on rotation in the field. Good luck with that.

    Remember that the “H” in “HARM” is for “High Speed”.

    Ramjet engines tend not be a high speed design (Meteor) and multi-mach air-breathers are either too big or sacrifice payload to get range & speed.

    Then again, there is the KISS principle to consider.

    Given the timelines, and the fact that its a Navy only program its quite likely that the Navy would just look to take it out of the block development program or insert it towards the end of block 4 since priority would be the Growler given the mission.

    Give it UAI drivers and they won’t be tied to any one block. UAI is also mentioned in the UAI budget doc for the F/A_18, but no timeline given.

    So does it fit or not.?

    The budget doc only says “F-35C aircraft integration” but the mfg and previous press releases have said it’s internal.

    Given the radical redesign (10″ to a 11.5″ motor, strakes instead of large forward fins) apparent in the above photo, internal carriage in the A/C should not be an issue.

    Interesting that we are seeing an AARGM-ER (F-35 int compliant) now as the only time I saw it on the schedule, it was for Block6 integration. I wonder if they are moving it up to Block4 (4.3 or 4.4)?

    AARGM-ER retains the same guidance, sensor, and warhead capabilities of the Block 1 AARGM.

    Their goal for the AARGM-ER IOC is 2023

    There was also the ejections seat.

    You are always going to have small issues creep up.

    The thing with the seats had to do with light-weight pilots that don’t exist in previous systems and always pointed to a “risk” of injury, never a certainty or anything widespread.

    The engine rub issue was another of the areas where they missed the boat a bit. I am not sure if it was even something they could have tested for or it may have just had to happen on a live airframe to discover.

    The one engineering problem I can think of right now which could apparently be classed as “incompetence” is the initial tail hook design on the F-35C

    The USN has already accepted blame for that one. The provided LM with bad numbers. I can dig it up, the subject came up at a recent Tailhook convention (great resource to get hours of talks from USN pilots).

    There was one ginormous ****-up that they did do however, they did not properly account for the weight of “empty space”. Since the X-35 did not have weapons bays, the bays needed to be designed into the F-35 after the contract was awarded. When they began calculating overall weight, thrust, engine performance, etc, they did not properly account for the extra weight penalty that internal bays large enough to accommodate 2k bombs would impose on the overall envelope. Because of this, they initially designed the F-35B to also carry the 2k load even though the spec said 1k. This underestimation of the “empty space” penalty eventually lead to SWAT weight-reduction effort of the 2004. The KPI reductions that the program had to also do in the late 2000s directly relates to this.

    In this instance I don’t directly blame MBDA. It was likely the reporter reading a report of a report, of another report, etc, etc.

    I don’t mind mfgs making claims (like kill ratios) as long as they give it context.

    Take the following for example. In this slide, LM clearly defines what it means by “Legacy” aircraft.

    Other times they are not as clear.

    Engineers from the European firm MBDA, which builds the missile, have reportedly claimed that the Meteor has a “no escape zone” three times larger than that of the AIM 120B AMRAAM missile.

    FIFY

    The original quote where this came from is

    Meteor has a No Escape Zone three time greater than AMRAAM it is designed to replace.

    When Meteor development began, European forces were using the AIM-120B so that is the model it was “designed to replace”.

    How does having multiple nodes affect surprise?

    Better to have the capability than not, despite the slight relay delay timing.

    You do realize that MADL is completely automatic and requires no human interaction, right?
