    Originally I was questioning whether the Meteor would be compatible with the limitations of the air to air station of the F-35 (350 lbs). Specifically, since Meteor is a phyically larger heavier weapon, if it at 400+ pounds could fit on stations 7&5 then this would be a positive regarding future missile upgrades. Lastly, the operational impact for UK and other users who would have to use air to ground station to carry it instead of ground ordinance. UAI will ease integration issues for future weapons, not physical limitations of weapons bay and stations. Thoughts?

    I remember that chart, curious if that was published pre- zeroing out the funding for JDRADM in 2013. Thanks, interesting topic, food for thought.

    BIO- interesting video

    I thought one of the more telling exchanges occurred when the gentleman asked about the air to air weapons available to the F-35, there was considerable hedging in the answers considering the kinematics of the AIM-120. It is clear that there is an internal discussion going on as to the suitability of the AMRAAM as the principal air dominance weapon moving forward. This brings up a slew of questions as to how the defense industry is going to solve the question of improving the kinematics of the next generation of air to air weapons considering the space limitations on the F-22, and to a lesser extent the F-35. Anything larger than an AMRAAM sized missile is going to impact the number of missiles carried. Consider that the F-22 could only fit four AIM-120 until the clipped wing variant, and I don’t believe there has been a fit check on the suitability of the Meteor on the air to air station of the F-35 (hinting at a limitation on the size of weapon that station can carry). Clearly, if there is going to to be an increase in range/ and or/ burn time on the next ten air dominance weapon, it is going to have to have a HTK capability similar to the CUDA to fit a larger motor or ramjet in an AMRAAM sized airframe.

    …….either way: we can conclude that the powerpoints telling us how F-35 wouldnt need support a/c like jammers & top cover and therefore be cheaper is moot

    If one wanted to base that supposition on a Boeing Grower powerpoint, and Russian radar manufacturer brochures.

    How many jets have been built? How many hours flown?

    By now, there is plenty of data to calculate production costs at different rates, cost per flight hour and the rolling cost of hardware and software upgrades.

    If those numbers have not been generated so far, the program should be cancelled and all involved should be encouraged to apply for entry-level positions at Wal-Mart.

    Costs per flight hour will fluctuate over the course of the aircraft’s life, there are plenty of examples for that (B-1 comes to mind) The F-22 operating costs are coming down as the aircraft matures, they are still trying to pin down the sustainment costs though production has ended:
    http://www.fas.org/sgp/crs/…/RL31673.pdf
    The F-35 sustainment cost outlook does seem to be improving as reported in the SAR report, various media outlets and blogs have their own spin on this:

    The railgun will be a powerful means of defense against pink flying unicorns.

    FBW – STOVL directly added >1500 lb of engine weight (vs 2 x F414s). The giant storm drain down the middle of the fuselage complicates loadpaths and system runs (a factor in the 2003 weight gain). Now add growth factor to all those margins. As A500 says, the length constraint (the jet is 14 feet shorter than the Shornet, even with the long tails) and the forward fan bay are what screw up the transonic drag.

    All true, adding length would have helped transonic drag , area ruling could have been improved, etc. The problem is that I think we would be looking at a 35,000 lb fighter. I don’t think for a second Lockheed would have been able to control weight growth when you look at the experience with the F-22. Without keeping the airframe dimensions the same, any savings from commonality would have gone out the window as well.

    As long as the requirements aren’t too disparate, then the USAF and USN can share.

    The USMC are out the door though, their “me too” approach has f**ked JSF up something shocking.

    I know this is the conventional wisdom among many who feel that the design constraints of the “B” model led to too many airframe compromises. It could be argued that the drive for commonality among the three airframes limited the optimization in certain parameters (tailhook position in the C).

    The counterpoint I offer is that without the B version’s VLBB requirement the weights of all three variants would have continued to grow. The wingspan limitations imposed by LHA lifts on the A+B variants largely saved them from the acceleration issues plaguing the C model (in both drag and weight). In my opinion, the F-35C is the most compromised, and contains the most technical risk. Frankly, the fact that the C version weighs almost 5,000 lbs more than the A model is a major concern.

    How do you see this happening? The gap in the time frame is almost a decade if not more..The USN is going to need to replace the early made SH’s much earlier than the USAF wants to replace the F-22’s..not to mention that for the USAF they major Procurement $$ will be going towards the LRS_B.

    By 2035, the air force is going to be facing: airframe hours on the remaining F-15C’s running out, F-15E needing a replacement (late 2030’s according to previous plans), the retirement of early blocks of the F-22. Given the current fiscal state, I don’t see how the DoD is going to afford two separate air dominance programs. By the time the F/A-XX program starts gearing up in the early 2030’s both services will need new airframes.

    Fact is, a USN carrier was a much more dangerous opponent in the 1980s than it is now. It’s relative power will be even more diminished 10 years time.

    That is a stretch, there certainly is one area where the Navy has lost capability. That is in long range interdiction missions. That was due to the A-12 debacle. The capabilities of the A-6 have never really been replaced. The F-18E/F may not have the legs of the F-14 but is a much more capable weapon system, however unsexy. The S-3 was never really replaced, but I’ve not read anything where the navy considers that a gap in their capability.

    I don’t see any way that the Navy gets the F/A-XX with single service requirements. The NG Tacair (F-X) and the F/A-XX programs will most likely share one platform.

    True, but still as expensive as a Gripen NG…

    Where is there a quote for Gripen NG at 46 million per?

    The Gripen C/D was listed at having a unit cost between 40-50 million.

    Twi engined typhoon do not hit 105 dB end of runaway afaik…

    swiss report 114 dBA (115 according to article below for afterburner at 305 meters) for the Typhoon. F-35 dBA at 115 according to this article protesting F-35 basing in Vt. Then 152 dBA according to the article above about navy ear protection.

    Doesn’t the RCS also fit in here somewhere..?
    The Big Jabba The Hut gets the little Jabba The Hut slung underside its fuselage.. 🙂
    Seriously.. it allways cracks me up Reading about these wonderfull proposed NGJ program for F-35. How many years has it been since i first read about this?
    I mean shouldn’t they first get the NGJ pod into the state of solid matter and fitted on the Superduper SH before we even speak about any F-35 Growler!?
    And to make my point about any future F-35 With NGJ program being somewhat of a distant star right now.. just have a look at the F-22 and its Upgrade programs, not exactly breathtaking is it.
    I’ll get my coat on the way out.. 🙂

    NGJ is slated for the EA-18G only for the foreseeable future, RCS issues associated with a EW pod would seem secondary for an aircraft actively jamming opposition radar, no?

    @Amega

    Yes, and tomorrow’s lesson is on:
    D – R – A – G
    tonight’s homework is to write a 50 line essay on: “What is the difference between a drop tank… which you can drop, and a much heavier jamming pod… which you cannot drop”.
    [Submissions using MS Powerpoint are not allowed]

    Admittedly, your stance is openly hostile to the F-35 program and that’s fine, your entitled. But don’t you think it’s a bit disingenuous to point out drag issues with an external pod when most aircraft carry ordinance externally? And no fighter carries an internal jammer powerful enough to protect a strike package since the EF-111 was retired. Secondly, many aircraft use ram air induction for cooling with the notable exception of the LO aircraft in U.S. service

    What does that have to do with the F-35? Lets keep things on topic guys..

    Actually quite a bit if you look at the link. Boeing claims the F-35 will not survive without the broadband jamming spectrum of the Growler. The whole PowerPoint is making the case for Growler + F-35. It fits right into the discussion going on. Frankly, I want to hear some opinions on this.

    F-35 service ceiling is 60k ft about the same as EF-2000 , nevertheless almost all aircraft can do a zoom climb to alot higher than their service ceiling before launching their missiles , and since F-35 detect EF-2000 first it will have the option to position itself best way possible which mean in real life the f-35 will even have the advantage in altitude as well

    I would take that with a huge grain of salt. The quoted service ceiling of fighters is not particularly useful and neither the F-35 or any other turbofan powered fighter is reaching upwards of 60,000 feet without afterburner.
