    you mean, those industries they’re burying deep and for good in exchange of screwing some bolts and entirely depending on good will from somebody on another continent to keep their… er… thing fly?

    Nope, I said as well as having their own fighters, they also have their own fighter projects.

    Right now the UK has everything France has. It’s own domestically developed fighter and the Taranis/FOAS project. But it also has the F-35 share. So come mid-2020, the UK will have an AESA-equipped domestic fighter and a stealth fighter, whereas France will have the Rafale and some tatty old Mirages.

    I insist on one thing: the same manufacturer produces both, and qualifies one as BVR the other as WVR.

    It is written clearly on their website and all data they provide.

    It is called “reality”… you, on the other hand keep insisting that you know better than people who make them how the two compare between each other… troll

    Not really. MBDA is multinational. UK weapons come with UK advertising, fRench weapons come with French advertising (which is normally grossly exaggerative). For years the RAF quoted ASRAAM as 15km, which was comically conservative and MBDA stated nothing. Then CAMM came out quoted as >25km and so they wrote the same for the ASRAAM, because even a complete melon head could have worked out as much.

    It’s not “mistakes”…

    after being corrected he would’ve stopped posting his bs.. keeping doing it on purpose is called trolling, not mistakes

    Insisting BVR and WVR are not subjective is also trolling.

    Now that we’ve established 200mm of the CAMM’s additional length is for the gas divert after launch, that means the missile segment itself is only 100mm longer. So it’s your position that with an extra 10cm on a 290cm missile, it went from 1/3rd the range of a MICA to >25% greater than a MICA? What exactly is in that 10cm? Some kind of nuclear fusion propellant?

    No, the onus of having to provide proof goes to the man who:

    * dissents from the documented description of the missile,

    * imagines that when I saw production missiles at different stages of construction but with no datalink and antenna present that I was somehow failing the see this secret undocumented feature, and

    * thinks that when delivering formal and informal briefings MBDA officials somehow forgot or overlooked the presence of a datalink, and managed to keep it secret for more than two decades.

    (When Israel announced the Derby, it claimed that the missile did not have a datalink., but even with Israeli-type security, the truth that it did have one emerged within a year or so.)

    EVERY post? Each and all 1,200+ plus of them? Nonsense.

    All I was trying to say as politely as possible that for the next few weeks I will be unable to respond to any future mistakes you may make in your postings.

    *The documented description does not state ‘no data link’.

    *Someone who insists ASRAAM is the only AAM in the entire world that can somehow perform LOAL and OTS shots without a datalink.

    *Oh that old thing again. You mean this briefing, that ended with a Q&A, that suddenly became a factory tour as the argument progressed:

    But the technical press is unlikely to place much faith in a briefing from a PR guy, and companies know this. During my visit to the Saab pavilion at Fbro, I found a press briefing under way. It was being given by a senior member of the project team (not by a spokesman or salesman), who then invited the press into a side room where he could continue in greater detail. Any experienced PR man will tell you that this sort of briefing ends with Q&A, folloewd by one-on-one sessions.

    Yeah, that sounds a lot like a factory tour to me.

    I prefer (oops, that now needs to read ‘used to prefer’) to get my information first-hand from companies rather than trawling the ‘net. So the only source is an MBDA briefing given to yours truly.

    Mistakes like saying a briefing ended with a Q&A and then saying it actually ended in a factory tour later.

    No, but it might be wise to purchase your fighter fleet on actual capabilities rather than promises.

    And the F-35 may be the best choice for nations who don’t mind outsourcing their air force to the USAF as long as they get low tech industrial leftovers ? :p

    Not really, and any risk is minimised simply by the weight of orders behind the F-35, and frankly I’d say the F-35’s current capabilities still massively outweigh those of the Rafale.

    There is no outsourcing of the air force, it’s just protection of intellectual property, it doesn’t affect usage. What India are basically looking for is a how-to guide, so they don’t need poor gullible imbeciles to sell them aircraft in the future. Hence why they only bought 36. Surprised they didn’t just buy 1 but I guess that would have made it too obvious.:p

    And BTW, nearly all the countries buying the F-35 have their own domestic fighters and domestic fighter projects.

    The video you posted is a compilation of footage from different trials. You cannot assume that a launch and an interception shown consecutively are taken from the same trial – this is a product of the public-relations department, not the engineering department.

    During a missile development programme, most test shots are telemetered rounds – engineers want to monitor what the missile is doing. Other test shots are made without telemetry, and with a live warhead fitted (After all, one needs to demonstrate that the missile will perform as intended.) But if you are tasked with compiling a PR video, which type of trial would you use footage from – warhead shot or telemetered shot?

    To prove your datalink claim, you need to direct us to a document published by the manufacturer, or the user, that clearly indicates the existence of a datalink. Unverified claims on enthusiast websites (if you can find any) are not good enough.

    But the detailed design beneath the skin is different, so it is not (as you claimed) ” literally an ASRAAM with a seeker change and 10% longer”.

    I have briefly explained this already in an earlier posting… It is series of sideways-firing nozzles mounted between the cruciform control surfaces and the rear of the missile. The missile is vertically launched, being expelled from its launcher by a sealed cold-gas ejection mechanism. Once the missile is clear of the launcher, gas generated within the missile is ejected from the sideways-firing nozzles to turn the missile towards the required direction. Only then is the rocket motor ignited.

    Some years ago MBDA released a composite photo of a turnover trial, and the efflux from the thrusters was clearly visible. Various magazines published it at the time, and Jane’s has published at least one photo of the missile rear end that shows where the gas ports are located. The MBDA website also has artworks showing how the thrusters fire. So (unlike your non-existent datalink), the existence of the turnover subsystem is well documented.

    And with that I need to finish packing my suitcase. Departure for a foreign trip is but hours away.

    But you can assume that it doesn’t, even though it’s the same intercept profile?

    Nope, I just need to point out the OTS shot and the video footage and the fact I was informed of it by an MBDA engineer who didn’t change his story. It’s you who has to provide evidence to refute this.

    My point was that the propulsion was basically the same but with a bit more propellant and that’s all I need to prove for this purpose. It should have been clear that I was being curt.

    Well if that system takes up 200mm, that would imply that the amount of extra propellant is very small indeed and the missile is heavier but still outranges MICA VL by >25%.

    Nobody needs snippets from your diary at the end of every post, this isn’t twitter. And with that I’m off to take a sh!t.

    That must be an old version of the AA-11. I wouldn’t think an IRIS-T could out-range the latest one (40+km).

    Has a few other inaccuracies as regards HOBS FoV too. ASRAAM is +/-90deg.

    http://defense-update.com/newscast/0309/asraam_loal_test_130309.html

    Futhermore, both MICA and IRIS-T use a 2×128 element array.

    1. I am not French

    2. I said that as of today, perhaps Rafale may still the best choice due to the lack of maturity of the F-35, but that in a few years this will change and then the best choice will be F-35 (although another qualifyier is still needed — that this is of course considering technical capabilities only, and not other factors like ToT, offsets, politics, etc. — if those other factors are considered then Rafale may still be the preferred choice as recentl witnessed in India)

    Yeah, because everybody buys an aircraft just for today and to hell with the next 40 years right?

    So basically the Rafale may be the best choice for developing nations so that they can steal technology.

    Blabla…blabla…
    Fed up to discuss with this uneducated guy.
    The only fact is the one made by MBDA:
    MICA: BVR
    ASRAAM: WVR
    I guess that alone should be sufficient for Lukos.

    ASRAAM 5+km OTS shot at sea level. MICA IR not.

    BVR, WVR, long, medium, short, all subjective, non-quantitative terms.

    Sarcasm aside isn’t SR-71 faster than Mig-25/31?

    Yes. Pilots confirm speeds of over M3.5.

    In Love With the Blackbird
    It is a race this jet will not let us lose. The Mach eases to 3.5 as we crest 80,000 feet. We are a bullet now – except faster. We hit the turn, and I feel some relief as our nose swings away from a country we have seen quite enough of. Screaming past Tripoli , our phenomenal speed continues to rise, and the screaming Sled pummels the enemy one more time, laying down a parting sonic boom. In seconds, we can see nothing but the expansive blue of the Mediterranean . I realize that I still have my left hand full-forward and we’re continuing to rocket along in maximum afterburner.

    The TDI now shows us Mach numbers, not only new to our experience but flat out scary. Walt says the DEF panel is now quiet, and I know it is time to reduce our incredible speed.

    You have once again my point of twisting data and being an dishonorable LIAR!!.

    [ATTACH=CONFIG]248760[/ATTACH]

    1- Eurofighter.com says “with a full Air-to-Air Missile fit.” It says f**ng missiles. No 1000l fuel tanks. It actually doesn’t even say full internal fuel, I assume as such for the sake of argument and comparison; If an F-16 beats or matches Typhoon performance with 100% fuel, that it will certainly beat it in lesser fuels. Since F-16 does just that, I don’t bother an argument of how much fuel Typhoon may be carrying, it doesn’t matter if its 100%.

    2- Eurofighter.com says 200kts to M1,0, NOT from “brakes off”. And NO “<30” seconds it says “in 30 seconds”, not “less than” or “under”. I don’t need to add a milisecond because F-16 manual gives EXACTLY that; with full fuel and A-A payload, from 200kts to M1,0 in 29,3 seconds.

    3- BAE systems website does NOT even say “with full Air to Air payload” like Eurofighter official website do, let alone your 3x drop tanks BS. You are take a claim from Eurofighter website, inflate it with your BS (this time by adding 3x1000l tanks), then you try to pass it as something taken from BAE’s website…. Most (actually the ONLY) logical explaination for this contradicting data between two official sources is BAE system give data for Typhoon with much lighter payloads.

    1-brakes off to 35k feet M1,5 under 2,5 minutes with full A-A missile fit.
    2-brakes off to 36k feet M1,6 under 2,5 minutes with unknown payload… Maybe for a clean aircraft with 50% or even less fuel.

    1-200kts to M1,0 in 30 seconds with full A-A fit.
    2-brakes off to M1,0 under 30 seconds with unknown payload.

    For the 1st claims, F-16 beats Typhoon in acceleration and *MAYBE* just a few seconds slower in climb. I am not so certain its slower as I didn’t do an optimal climb profile.

    I don’t have a comparison basis for the 2nd claims, and I simply ignore them, and I have no idea why you keep bringing these up (like you did two years ago with your “Lukos” alias). Payload and fuel is VERY important to make a valid comparison.

    No fuel and payload criteria? Then it doesn’t tell anything about the performance of the aircraft.. Even an F-4 can climb from 0 to 35000 feet in 42 seconds given its light enough. I won’t do the whole math, but this sufficently light F-4 could probably take-off and make necessary accelerations in the remaining 208 seconds, maybe miss it by a 5-10 seconds at best.

    A simple “take off, accelerate to M0,9 climb to 35k feet, accelerate to M1,5” profile takes 150 seconds on F-16 excluding the 8-12 second take off part. For the 300th time, F-16 can achieve better climb time above 20k feet if its supersonic (instead of keep climbing at M0,9). It also accelerates to M0,9 to M1,5 full 13 seconds faster at this altitude (53 seconds @20k feet vs 66 seconds@30k feet), so it can shave quite a few seconds from that overly simplistic 150 second time.

    I can make time calculations for this relatively more optimal climb profile for F-16, and Climb and Acceleration time is perfectly calculable from climb-rate graph of MiG-29, but I don’t think anyone else is interested, and I won’t waste my 50 minutes for you. My point is crystal clear; Typhoon is only an even match for a Block 50 F-16 at best, and MiG-29A has 22% to 62% better 1G excess power compared to same F-16.

    I don’t have any stomach left to discuss with you. You win OK? I was wrong and this Lukos/Starfish guy was right all along..

    Starfish/Lukos says:

    -Su-27S has the highest (subsonic) sustained turn rates of all 4th gen fighters at mid-high altitude, but Typhoon has it better.
    -Su-27S has the highest (subsonic) sustained turns of all 4th gen aircraft when fuel weight is equalised for same range, but Typhoon is better.
    -F-16 blk30 has the highest (subsonic) sustained turn rate among all a 4th gen fighter with 50% fuel, but Typhoon is better.
    -MiG-29 has the greatest (subsonic) climb rate value among all 4th gen fighters, and greatest off-the-deck climb performance, but Typhoon is better.
    -MiG-25 and MiG-31 are the fastest combat aircraft ever entered service, but Typhoon is faster than those when carrying EFTs (M2,0 vs M1,7 and M1,5 for MiG-25 and MiG-31 respectively)
    -F-15E with PW-229 is the fastest fighter aircraft with heavy payloads, yet Typhoon with 8 missiles and 3 EFTs is faster than F-15E with 8 missiles and no EFTs but only CFTs (M2,0 vs M1,9).

    All that subsonic performance, despite the fact Typhoon is designed for high-altitude supersonic regime.
    All that impressive high mach top speeds with EFTs, despite puny 90kN engines and a fixed inlet.

    These should say how Typhoon is the bestest product mankind has ever made. Happy now?

    Speaking of climbs, a nice video of MiG-29’s off the deck climb with centerline fuel tank (this is the first time I’ve mentioned this fuel tank, since we are idiot enough to think every hanging EFT is fully loaded with fuel during airshows)
    https://youtu.be/VCWjByenDsM?t=40s

    Not that I would claim for a second Typhoon is any worse than that of course. Even without no evidence, Typhoon is better because it is the bestest aircraft.

    1. Full AAM fit is basically the standard QRA load, which is 4xAMRAAM + 4xASRAAM + 3x1000L DTs. It’s evidently a lot slower than the clean figures BAE provides, so DI is certainly not zero.

    2. Irrelevant, the BAE figures are for the clean aircraft, the GmbH figures are for a loaded aircraft. You can argue about the load all day but clearly it is loaded and the DI is not zero.

    http://i1281.photobucket.com/albums/a508/sigmafour1/bae%20typhoon_zpsh8uyaxgo.png

    3. That’s because the BAE figures are clean, just as the original F-16 figures were. That’s what DI=0 means remember.

    The ‘unknown payload’ is clean. DI=0. The GmbH load is DI !=0 and likely implies the standard QRA fit given the performance delta with the clean figures.

    Yeah, because for the first claim you are comparing DI=0 with DI != 0. When you compare DI=0 with DI=0, the Typhoon wins by over 30s. How seriously disingenuous of you.

    Sure you do, you have the DI=0 figures. And even at 20,000lbs GW (i.e. less than empty, empty weight was actually over 20,168lb, so they must have removed stuff https://info.publicintelligence.net/HAF-F16-Supplement.pdf), the F-16 can’t get from brakes off to M1.0 in <30s. 19s from M0.3-1.0 + ~12s for M0.0-0.3 gives 31s. Get the picture yet?

    At 24,000lb GW, which is about half fuel only, it’s at 34s M0.0-0.98 and still can’t beat the Typhoon to M1.6 and 36,000ft. So like I said, “no way, no how!” You just can’t accept that you’re wrong.

    http://forum.keypublishing.com/attachment.php?attachmentid=248669&d=1475487766

    The load is now irrelevant because I just proved that even at sub-empty weight the F-16 can’t beat the Typhoon to M1.0. And as far as that goes, the Eurofighter tech guide doesn’t specify fuel load either, it’s just assumed that it starts with full internal fuel on your part, whereas it’s likely the standard QRA fit, since that would be the most applicable to customers.

    Even if we play, the no DTs dice, it’s still 8 AAMs, so we’ll use the 30,000lb ground weight with DI=50 for the F-16 (which is still a lower fuel fraction and even 2 AIM-9Ls on pylons and adaptors has a DI of 22 and there will be 6 missiles on such, with 2 on the wing tips). I’m also letting you off on weight a little too. And you get 12 + 30 + 75 + 71 = 188s for rest to M1.5 at 35,000ft. Either way you lose by >30s. Give in yet?

    Yeah, excluding the take off part, which is included in both sets of figures (BAE “Brakes off to M1.6 at 36,000ft” and Eurofighter tech guide “Brakes off to M1.5 at 35,000ft”) and using a DI=0 and comparing it to a Typhoon with 8 missiles (and DTs too in reality – you can even verify this by examining the affect of different load-outs on the F-16’s performance relative to clean!). So in reality, even when you cheat like mad you still lose.

    I win not because you’re tired it’s because all your arguments were full of complete crap, and you used SEP as a substitute for true climb rate.

    Where did I say EF was faster than MiG-25/31? Strawmanning. I said it was faster than M2.0. Never made such comments about the F-15E either.

    Took way longer than Typhoon to take-off.

    oh, so, shooting down stuff beyond 50km is WVR by your standard?

    so ASRAAM is BVR with 20km-something range and MICA is WVR with over 50?

    tell us, are you just acting as an idiot or is it for real?

    All modern SRAAMs are capable of BVR, that’s what everyone is saying. No modern SRAAM is rated at less than 20km, which is technically BVR but that doesn’t make it medium range by modern standards.

    Range depends on altitude and launch parameters. 67km at 40,000+ft in a head-to-head engagement is actually less kinematically demanding than a >5km range OTS shot at sea level, as the AMRAAM graph shows. It makes 70km at 40,000ft head-on, but in a tail chase at sea level it’s limited to 5km. An OTS is essentially the same (0mph relative speed at launch) except the firing and target aircraft are swapped and the missile is being fired in the wrong direction and has to make a turn. So really it’s harder, because the missile first gains a negative closing speed, before swinging round.

    Not just for that test. The normal practice during development firings of small tactical missiles is to replace the warhead with a package that contains a telemetry system and its associated transmitter.

    Well that’s odd, because the same firing from the external view results in an explosion. I think that combined with my MBDA source, who didn’t change his story, is proof enough.

    https://www.youtube.com/watch?v=cKN_2ViE4eM

    It is not literally a modified ASRAAM. Much of its ‘innards’ have been redesigned to use newer technology and to avoid component-obsolescence problems. These re-engineered subsystems are now being fed back into ASRAAM in order to create the new production variant.

    When Roxel displayed in CAMM motor at Eurosatory 2012, they stated that it was based on the ASRAAM motor.

    Also remember that up to about 200 mm of that 300 mm of extra missile length was needed to house the turnover subsystem.

    Yes the updated ASRAAM will be using all those components but there is no fundamental difference in propulsion or air frame design aside from the 10% length extension.

    Yeah, specifically it’s the ASRAAM propulsion section with an extension.

    Turnover subsystem?

    well there were people who chose the rafale: halloween, loke, nikola, topheat, or in other words all the french guys, chose it over the f-35. and msphere, who is generally anti-us aircraft
    all the ones who chose the f-35 are: starscream, obligatory, mig-31m, basically all the Americans

    for me personally, I like both and still on the fence over whose cons are larger than the other.

    I cant read Russian but isn’t it the AIM-120b according to what written in there?

    Not sure, I can’t read it either, but going by the range of 105km at ~53,000-66,000ft, I assumed it was a C-5. It could be a B though, indeed it would make more sense if the ASRAAM was kinematically similar to a B in a low altitude tail chase. I doubt it’s up to the C kinematically. matching an AIm-120B would still put it at 75-80km in terms of maximum range at altitude (43,000ft in graph).
