    The F-35 will probably be faster if it gets a variable cycle engine in the mid 20’s, but even at that, it will have a relatively low supercruise and top speed, way below what the PAK-FA will be capable of.

    The 4th gen fighters had all pretty much the same effective speed, except for the F-18 and tornado F-3. At least the F-18 and tornado had good excuses for that, the F-18 being a navy fighter and the tornado was not meant to face fighters.

    On another hand the F-35 is massively outclassed against the PAK-FA in terms of effective speed, that is the problem.

    The Aim-9X Block III was put on hold (different from an outright cancellation since the requirement remains) because of budgetary reasons. If the USN did not do it on its own, the Congress would have done it. As I mentioned, a lot of the fruits of the AII are expected to begin appearing in the FY18 budget (Some started in the FY17 budget if one looks carefully) including the fighter AOA, AWACS AOA, New missile projects and sensors. The Aim-9X enhancement, beyond the Block 2+ will be one of the candidate for those $$’s.

    Also, if they wanted a weapons bay ejected -9X Blk. 3 they would have specified that in the requirements. Its not the case of developing the requirements, and then seeing whether it can be ejected. That’s looking at the process backwards.

    The CUDA is a Lockheed Martin design concept, meant to support a program that is currently being executed. Lockheed has done a lot of leg work on their own. The Program awarded a contract to Raytheon, choosing it over Lockheed. The FY17 funds two new weapons in the air-air context. One is the CUDA class, the other is a self-defense short range kinetic interceptor. Both will extend to FY18 and beyond. Meanwhile, Lockheed will continue to invest in the CUDA as they see fit.

    Regarding the design – Its nothing that is seriously being considered. They won’t publish anything that is going to shed light on their design thinking a decade prior to an actual competition .

    I don’t doubt they will do an AOA, will they take the right decision that’s another story. Hopefully with the F-22 and F-35 semi-fiascos they will have learnt their lesson hard.

    The fact that the 9X bl2 and 3 were not modified was also stupid.

    LM will probably continue to work on the CUDA to make the F-35 better, but what the plane needs the most is the best BVR missile possible, at least something equivalent to the meteor, and if possible a new gen missile. That’s what it takes to compensate for its inferior performances. If they don’t push for that, it will be one more bad decision among so many taken by the USAF.

    The program past the Block II+ Is looking pretty thin so there is room to work at that with a new block III (with the older one having been shelved) if that is a pressing requirement. The FY18 budget is expected to bring a host of goodies for air-superiority systems (Fighter AOA, AWACS AOA, missiles, and sensors etc) with an eye out into the future so perhaps this is something they can look at.

    Maybe the AIM-9X block III has been cancelled because it could not be ejected from the bays of the F-35, I don’t know. The primary goal of the missile was to give the SH 2 more BVR missiles in a2g configuration on the wingtips. I don’t know what’s up with the CUDA or the next gen short range missile.

    Had the 9X bl 2 been designed to be ejected as well as rail launched it would have solved the problem for the F-35 but initially they wanted an extendable rail launcher for the internal bay. It’s been cancelled ( doh ) so they have to carry the HOB missiles outside.

    Whatever the next generation proposal from LM turns out to be, its a virtual guarantee it won’t look like anything above. They aren’t going to release anything that will give a sneak peek into what their team is doing.

    This design is quite good. That kind of intake enables to have a flat fuselage and the wing is the extension of the intake. The side bays can be designed for 2 more missiles. That’s pretty good idea, I had that idea in fact hehe..

    If they chose that that design it will surely evolve. But the 6th gen may look completely different than regular fighters so we’ll see. They’ll probably want a lot of range.

    Last I saw it was still in the Block 4.something list of things to integrate.

    I do think they should make one of the weapon stations in each bay compatible with the AIM-9X which is supposed to be capable of LOAL. 4x BVR missiles and 2x all-aspect WVR missiles is a decent loadout for air-to-air.

    How do you do that, the AIM-9X is rail launched.

    Interestingly, the LM 6th gen may be designed to have side bays:

    Ok, first off you claimed you posted the F-35A KPP mission profile. I pointed out you did not, it is from Norway briefing for F-35A JSM mission. Next, you need to what different altitudes are classified as. What did I say “The entry and egress are at Med altitude for the KPP”- now look at the graphic you posted see where it says “egress at 25,000 ft, combat at 20,000 ft” those are medium altitude. Lastly, what does the AMRAAM have to do with JSM deployment? The F-35’s KPP is written for JDAM deployment. And again, the mix may differ from each variant, but they all include medium and high altitude.

    The range from the particular mission for Norway gives a indication of the kind of range the plane is capable of. With a relatively light load the F-35 can reach 610nm if it flies most of the time at 30kf. It is not a 2000lbs JDAM but for the JDAM it would obviously be less. With AMRAAMs the difference would likely be small.

    You obviously didn’t read the link. First off, does not have to be mach .6, the optimal cruise speed could be .65, .7, .75,.85 whatever. The point is, flying a CAP mission involves High altitude and optimal speed to increase range (no matter what platform you are talking about) Notice where it mentions a minute of combat? So, no it is not just a matter of flying out to 750nmi, there is combat time involved.

    This issue is, you don’t really know what you are talking about. I’m sure by the sound of your posts that you assume that fighters are flying along at mach 1.5 all the time in afterburner. Do everyone a favor, go look up “USAF mission planning” “mission profile”, google the from the Brazilian fighter competition to see the CAP mission graphics, then come back when you are not talking rubbish.

    1 min of combat, is that a joke or what? All this sounds like a LM propaganda to fool idiots to think the F-35 can do a2a at 760nm. Won’t work for people with critical thinking skills. Like I said even if it can do it, it is a pretty useless figure with little operational utility.

    And BTW in my initial comment about the range I said that 760nm would be a bit of a stretch. If they had said 680nm or something like that I would have said ok probably.

    And hum no I don’t think a fighter necessarily spends so much time in supersonic huh. But in some case when it is sent to intercept enemy planes yes it does and in that case the range would be a lot less obviously.

    Every single manufacturer is going to use a scenario that plays to the strength of their aircraft by comparison. Simply put John, which aircraft has a longer combat radius on internal fuel? Which aircraft could fly a cap mission to 750 nmi and be 9g capable throughout?

    1 min, you call that a CAP? AHAHAH! And what if the F-35 has to escape on afterburner because the enemy turned out to survive better than expected? lol I’d love to see what happens. Of course the F-35 is so good that it would never happen. 😀

    Your ignorance is truly breathtaking. Read what I wrote, they all have different mission profiles. The graphic you posted is from Norway briefing for JSM mission, not the F-35A mission profile for the KPP requirements. But as all, there are portions flown at High and Med.

    The fact that you think you “got me” with that is indicative that you’ve no idea on how altitude impacts range on any mission profile.You really have no idea what you are talking about. Most every mission profile will include high altitude parts at optimal cruising speeds. When you see most aircraft’s “combat radius” listed, they are a mission flown at optimal speeds and heights, unless mission profile is specified (Hi-Lo-Lo-Hi, High-Med-High, etc.)

    All CAP missions have a significant portion flown at optimal altitude. And yes, like all fighters, part of the mission profile would be flown at optimal speed, might be mach .6, .7 or whatever.

    The only thing that’s breathtaking here is your dishonnesty. First of all note that the JSM is a light missile compared to a 2000lbs weapon, so the difference with an AMRAAM instead in terms of range would be small. And in that profile, most of the flight is done at high altitude, which is optimal of course.

    Now if the speed is like mach 0.6, if it can really reach that range, what is the point of going to max range at mach 0.6 and returning to base immediately? If it is for CAP, that range is only to get to the patrol station where the tanker would refuel the plane, it doesn’t include time for an a2a fight, so there is really nothing to be impressed about.

    Again, talking without knowing what you are saying. Each variant has a different KPP mission profile and the ALL include combat time. The f-35’s includes ingress and egress at medium altitude.

    Which would be true of any interception profile, but that is not what Spudman’s graphic is referring to.

    You’re kidding or what? Even if it can do 760nm it doesn’t mean much, it could hardly use its afterburner at that range. Unless it does its a2a mission without using its afterburner I don’t see the point.

    Why would the F-35 have a flight profile so different that it would make such a big difference, that makes no sense. The only possibility like I said is that a few minutes of air combat are included in the a2g profile.

    Here‘s the mission profile for the CTOL. Most of the mission is done at high altitude.

    Fortunately I’m here to call your bull**** AHAHAH!

    Or maybe you’re gonna say that the F-35 flies at mach 0.6 during an a2a mission to save fuel… right? go for it I’m waiting. LOL!

    Little to do with weight, AtA and AtG mission profiles are completely different. The F-35A’s observed mission profile KPP performance is 609 nmi, so having a 760 nmi range at Hi-Hi-Hi is no stretch.

    The F-35 is supposed to attack at high altitude, so… maybe the strike profile includes a few minutes of dogfight on afterburner…

    But in an interception mission when the F-35 flies all the way to target on afterburner it is certainly a lot less.

    The F-35 being stealthy it might be able to use subsonic a2a tactics to lower it IR signature in some cases.

    Would a weight reduction of 8% with no reduction in drag lead to a range increase of over 20%? That sounds like a stretch.

    Here’s one from 2011 that still has it (but apparently not for 3F)

    http://i.imgur.com/31BDZxy.jpg

    Here they are testing them on the ground rig

    http://i.imgur.com/vpAsTXo.jpg

    While digging around.. found this…

    http://i.imgur.com/jMDocjY.png

    I had seen that slide also, it might have it, not sure. The CBU-105 i used only by the US and block 3F’s goal is to integrate weapons that are used by most partner countries. It is not in the block 4 notional roadmap:

    [ATTACH=CONFIG]246378[/ATTACH]

    The AIM-120D is not here either, don’t know if it’s normal or not.

    I just found that too from elp site:

    Department of Defense released a contract (4th paragraph) that would add the SDB to the list of air-to-ground weapons cleared (for USAF) F-35A’s by the end of F-35 System Development and Demonstration (SDD) phase. This same contract also removed the Wind Corrected Munitions Despenser (for example CBU-105 which is used to deploy BLU-108 “skeets”) from the list of weapons to be cleared by the end of F-35 SDD.

    The link on http://www.defense.gov doesn’t work.

    As for the F-35 pic with the CBUs, they are mounted on dual launchers ( BRU-55/57 apparently ) and I’m not sure those launchers are scheduled for 3F, so I’m not sure the picture is relevent to 3F.

    760nm sounds a lot. If the F-35 spends a significant amount of time on afterburner it would probably be significantly less. People say that the F-35 has better range than the F-22, but if one takes into account the fact that the F-22 can supercruise and the F-35 has to use its reheat, it may not be true for interception missions.

    Could be… in either case the basic point remains the same. At 3F the F-35 will be capable of undertaking the full range of missions that it can expect to be assigned with the exception of a handful of exceptionally rare scenarios that are covered by other planes. Once Block 4 rolls around we can expect to see a greater variety of more specialized weapons integrated.

    This whole line of debate is more than a little silly. If the F-35 can’t be considered fully operational without a dedicated anti-ship missile, anti-radiation missile, and a nuclear strike capability then not one of the Eurocanards are fully operational yet themselves.

    The F-35 program has moved more slowly than was planned, but it has still moved significantly quicker than the Eurocanards, delivering more capability earlier. (even if we use 2008 as the date for a “multi-role” Rafale, albeit a very limited multi-role capability without a targeting pod, that is still 17 years after its first flight. The equivalent date for the F-35 would be 2023, by which time we are talking about Block 4.)

    The F-35 has some concurrency costs, but those costs prevent there from being any orphaned planes like the Tranch 1 Eurofighters or Gripen As. (or needing to see planes gutted and rebuilt in the case of the first Rafales.)

    The rafale was delayed because of funding issues, not because of technical issues. The decision was made to replace the crusader ASAP with a french plane instead of the F-18 so it was extremely urgent to field the rafale M. The rafale is a pretty cost effective program, considering how much it cost to develop and field, and also considering that there was a naval variant.

    The F-35 is a program that had a huge funding compared to the rafale. It had huge cost overruns and was delayed because of lots of technical problems. And the F-35C has poor high speed performances and still has problems with its wings. I think France did a pretty good job in comparison with the funds available, and btw you rarely hear French complain about the rafale, because they don’t have the impression that the program has been such a mess. On another hand, it looks like most Americans are critical or even hate the F-35 because they think it was a rip off.

    70-80% huh? Didn’t you just accuse me of making up numbers? The F-35 is scheduled to receive the CBU-105 in 3F… should be just the thing for your column of vehicles problem…

    Some sources say the CBU-105 will be integrated at 3F, some say it won’t.

    For instance here it doesn’t have it. It seems to have been removed.

    This pdf from 2009 doesn’t have it ( page 12 ).

    Some charts have it but I think it was the original objective dating back from 2002 or so.

    Yeah I forgot about the ASTOVL huh. That’s the way the LM-JSF should have been built with the 3BSD design. And the idea that a delta or delta canard is not stealthy is BS, for instance the FB-22, Boeing’s F/A-XX, naval F-23, etc.. Building the JSF was not the right idea, the CV became a dog and the CTOL is not so good in TS and SS.

    You realize that the F-35 have tails instead of canards due to CV, do you? Not sure what your fixation is on bagging on STOVL

    For sure you don’t realize that several naval planes have no HT ( rafale, and concepts like F-23N and Boeing’s 6the gen ), maybe you forgot that. :rolleyes:

    Lol but its around the same dimensions as a F-16[ATTACH=CONFIG]246306[/ATTACH]

    I get the point. 😀

    One can see also the large size of the HT, which is due in part to the fact that the moment arm is short.

    Had they chosen a longer aircraft ( and slimmer ) with a delta wing ( with around 58 degrees sweep angle like on the Mirage 2000 ) the weight of the big HT would have been removed in favor of the wing, so more fuel would have been carried inside the wing. The ability of keeping the energy high for many turns is mainly useless nowadays, so a delta wing would have been fine. The delta still has a high pitch rate and can pull 9Gs.

    Bottom line: longer fuselage with less cross section, and delta. +canards and large flaps for the CV variant or a larger wing around 50 degrees sweep. Of course this is completely impossible with the STOVL requirement.
