    Sorry H_K, I’ve just seen your correction.

    Perhaps I’m not reading it correctly. What is the estimated airframe hours on the average Spanish F-1s?

    EDIT: Got it. Tally’s roughly with the SAAF hours, once the years of service difference is factored in.

    Those Ecuador F-1’s have seen lighter usage, relatively speaking.

    I’ve seen it mentioned that Libya may upgrade some of their F-1 fleet with French help.
    Are there any Mirage F-1ADs still airworthy in Libya?
    Would these be looked at too, or just the interceptor models?

    In fact, I would be most appreciative if anybody had any pictures of the Libyan F1AD, as pictures seem to be very scarce…

    I’ve heard the original design life quoted as 4,000 hours, but this was overly conservative…

    One F1 is known to have reached 7,319 hours (a French F1 CT) and the remaining F1 CRs will also be retired ‘early’ with around 7,000 hours. Their airframes are said to be in excellent condition, and only require 7-8 maintenance hours per flight hour… so who knows what’s the real fatigue limit!

    The issue with the Spanish F1s is that they are fast approaching the 4,500-5,500 hour mark, which requires a major overhaul. If Argentina is willing to pay for the overhaul, they should be able to get another ~2,000 hours out of each F1… probably good enough to take them to 2025-2030.

    Ok, so this, along with the Ecuador F-1 hours is starting to make sense.

    Had a look over at the SAAF forum, and it seems the Mirage F1AZ hours were around 1000 hours for the lowest used airframe, and around 2000 hours for the airframe with the most hours on it. It seems their average was around 1500 hours or thereabouts. They were used between 1975 and 1997.

    Spain also bought their Mirage F1’s in 1975, but used them for an extra 16 years to 2013, which accounts for their higher airframe hours quite neatly.

    Ecuador got theirs in 1978, and they are used up to the present day, but have fewer hours used, which indicates a much lighter use.

    Either way, in context of the thread, it does look like there are F1 airframes out there suitable for years of use, but any upgrades over an overhaul will drive the price up.

    Still, the Mirage F1 with an upgrade and suitable armed would still be a very good interceptor, and retain it’s proven strike capability IMHO.

    Does anybody know what sort of fatigue life the Mirage F1 was designed to have?

    Wilhelm, some people post cr@p on a daily basis such as Goldust with his silly DSI paragraph. It’s a clever concept but it’s not ground breaking and it’s only a way to control the air flow into the engines, the US experimented with it in the ’90s. Although it wasn’t called DSI back then, English Electric came up with a concept which basically done the same job as DSI, it was on the Lightning.

    Don’t like what I have to say (which is very often a hell of a lot more of a contribution to most posters), click the Ignore button.

    And, since this is an English speaking forum, why not an English link of the one Y-20 posted earlier?…

    You seem to bite at every rancid piece of bait hung out, across multiple threads.

    Why should I have to put up with inane witterings that have nothing to do with the topic at hand?

    I’ve never put anybody on ignore here for a decade, and longer actually, if you consider I joined in 1999 under a different moniker that got lost in the ether.
    I don’t intend doing so now.

    Far better if you just ignore Tigershark (for that is who you are replying to in his latest guise, as everybody else bar you knows, in either his Palembang or Goldust reiteration: either way, the DSI fixation is the dead giveaway.) and let the mods eventually take the course that may be slow, but will be inevitable.

    As the saying goes:
    “Never argue with an idiot. They will only bring you down to their level and beat you with experience.”

    EE Lightning and Golddust.

    If you can’t act like adults, and stop polluting various threads with your rubbish, perhaps the mods might be able to persuade you in other ways…

    Seriously, the other posters simply aren’t interested in your drivel.

    Please do not reply to this unless you have something of value to contribute to the thread topic.

    Cheetah airframes were expiring …

    No they weren’t.

    That’s exactly what I thought! Are they in good long-term storage somewhere? The F1 is supposed to be a long-lasting airframe…

    I too suspect it wasn’t really about airframe hours, and more to do with the expense of an upgrade.

    On the SAAF forum, there is a guy from Ecuador that has been posting about the Cheetah C being inducted. They are extremely happy with it, as it represents a quantum leap over an unmodified or non-updated Mirage F1, systems wise.

    Considering what the Cheetah C had all the way back at the beginning of the 90’s, it was actually very advanced.
    MFD displays, multi-mode radar, a completely self contained internal EW/ECM system, datalink, BVRAAM, helmet guided SRAAM, …etc.

    Whilst a lot of that won’t have been transferred when the Cheetah C was sold to Ecuador, enough of the basic architecture would probably be a whole decade or more in advance of what an unmodified Mirage F1 would be equipped with.
    I suppose they got a bargain with the Cheetah C, and an upgrade to the Mirage F-1 is not a neccessity or too expensive as a result.

    Still, from what I can gather the SAAF regarded the Mirage F-1 as probably a better platform than even the Cheetah C if suitably modified. The whole F-1 fleet was to go through a comprehensive upgrade, with the Cheetah C cockpit and avionics/ECM/radar/weapons fit (the architecture was designed with that expressely in mind), as well as various airframe tweaks, such as a new composite verticle tail with a new bulged base for avionics space, ala the F-16, and IFR probe.
    Certainly, a Mirage F-1 thus equipped 15 to 20 years ago would have been a very capable aircraft indeed, and probably still relevant for a lot of middling airforces today…
    The end of The Cold War and the resultant dismantling of Apartheid meant the Cheerah C was done, but the follow on Mirage F1 upgrade was cancelled.

    On the Argentine needs, the Mirage III’s are out of life.
    If I were in their shoes, I would look at an interim aircraft to maintain core capabilities and pilot hours.
    In this regard, a small purchase of Mirage F-1’s or Cheetah C’s would be a very good thing, with the proviso that it was cheap, and for a limited time only of no further than 2020 at the most, and only to cover the period of when a properly structured new fighter purchase is put in train and delivered by that time, that would serve for the next 20 years and more.

    Is Argentina planning on buying a few KC-390s?

    From what I can gather, Argentina has expressed interest in 6 aircraft, which was announced by Embraer.

    In context of this thread, one would think that the selection of a common platform to perform AEW, ECM/ELINT, Maritime Patrol/ASW, Airborne Refuelling, and Transport would make sense from a training, maintenance, and spares point of view.

    Even looking at their current reduced and old inventory, and in the hypothetical scenario of this thread, it would amount to at least 30 airframes, probably more.

    My initial post in the thread was along these lines, in attempting to completely renew the airforce, and reduce the hotch-potch number of aircraft types being fielded.

    2 combat jet types
    1 common platform type (KC-390)
    1 jet trainer/LIFT type
    1 turboprop/basic trainer type
    1 medium helicopter type
    1 light helicopter type

    Compare that to the current disparate types operated.

    For the inevitable one off, specialised or ancilliary roles, limited numbers of different types can be purchased, and perhaps operated in mixed squadrons, as is done by other airforces.

    Obviously F-18 Hamburg…. I mean Y-20 Bacons topic is hypothetical, and based around a 2 to 2,5% of GDP defence spend.

    With this is mind, and concentrating on aviation solely, and considering that it is actually not chump change like the small change the current armed forces have to survive on, I would do the following:

    Like it or not, The Falklands is an issue.
    With this in mind, some Su-27xx/Su-30xx or hatever derivitives. One of Argentinas primary problems in 1982 was that it’s planes were operating at the extreme end of their range, allowing very little leeway for anything really when over the combat zone.
    The Su-30 is ideal for this, with massive internal fuel capacity. I would ensure a retractable refuelling probe came with the deal.
    24 – 28 aircraft, or 2 squadrons worth.
    Leaving aside the Falklands, Argentina is geographically a very big country. Add France, Germany, Spain, Italy, and the entire UK together. Then add 3 more Germanies, and that is roughly the size of Argentina.
    So range would be useful in other contexts.

    Next, I would add something different. I would look to buy the J-31. If after testing it shows a substantial reduction in RCS frontally (Chinese espionage surely delivered shortcuts to their domestic teams already clearly working on this), I would ensure datalinking and AAM compatability with the Su-30’s. They have to come with inflight refuelling probes.
    4 Squadrons of these please, or 48 to 60 aircraft.

    It has been strongly suggested that the J-31 has been designed with consideration of a carrier borne variant in mind. Thus, this purchase could bear fruit later.

    Off to Brazil next, where I would purchase the Embraer KC-390 in Transport, ECM/Jamming, Tanker, AEW, and MPA.

    If not the KC-390, then something like the An-70, which seems to be pegged at less than half the price of the A-400M.

    Order more Pampa trainer jets.

    Pick a medium/large chopper, and order sufficient quantities. Eurocopter could be looked at. The small chopper is covered already.

    Expensive, but doable in a phased approach over a few years. You will have quite a capable force geared toward the single most likely touch-off point, The Falklands/Malvinas, but also quite capable on other Argentine requirements.

    The driving force must be compatability in the way these units communicate with each other. An absolute essential, even if it takes an indigineous data-link system between them all.
    Over long range, you’d want the AEW, Su-30s, and J-31s putting each other in the picture, or handing info off to each other at appropriate times.

    Why so little Western European/US sharp point combat equipment?

    I would think it rather obvious, seeing how some of those suppliers compromised the Argentine force, whether they were right or wrong, before.
    And they are, after all, within an economic and loose political union.

    It is also not 1945-1991 anymore.
    The world keeps revolving, and moves on, with different players in the game now.

    All hypothetical, and IMHO of course.

    Political realities would likely prove very different.

    Getting back on track, and quoting myself above, others have mentioned Brazil.

    Assuming that the conditions are as they are in the original thread post, then a closer relationship with MERCOSUR partner Brazil is sensible.

    Brazil is another big country.

    Obviously the aviation industries of these two countries is firmly weighted in Brazils favour, but co-operative projects would likely lead to more stable projects. Well, certainly more funding.

    I suspect Brazil will go with the Gripen, but perhaps a “top end” longer range fighter purchase could be locked in together. Something along the lines of Rafale, or even, the PAK FA. Did I imagine that there was talk that Russia would have been interested in Brazil as a PAK FA market eventually, or was I imaging things again?
    Corrections welcomed.

    In the hypothetical scenario given, perhaps the Pampa and Z-11 helicopter being built in Argentina could be purchased by Brazil, with a raft of Brazilian projects for Argentina.
    This would also serve as a stable supply of external parts, regardless of what was happening politically.
    They could select whatever medium fighter serves their needs, and collaborate on the purchase of the “heavy stick” long range combat aircraft.

    Seems to me that the topics are basically inseparable unless it is stipulated for the discussion that Argentina has renounced its claim to the Falklands. So long as that isn’t the case, the ability to retake the Falklands will remain a key objective guiding any military development program. That’s why the military exists, after all — to execute the political will of the state.

    Agreed, which is why I included it in neutral terms in my theoretical post in this theoretical thread about what I personally would purchase and why.

    It is possible to have a perfectly polite and theoretical conversation about this and acknowledge that operational need without the usual tub thumping, although some clearly aren’t able to do so, for whatever reasons.

    Interesting.

    I did a bit of a double take because I have this (probably unfounded) impression of the M53 as not very powerful, but then again the TF-30 was no powerhouse either.

    Are the TF-306 and M53 similar in size?

    The M53 is quite powerful.

    The TF-306 was closely related to the TF-30, which was a pig of an engine, well, for years and years at least.

    The TF-306 went up incrementally in dry/afterburning thrust from:

    5200kg/9100kg then 5700/10 000 then 6500/11 000

    weight was around 1750 to 1800kg

    length 5,3m

    diameter 1,2m

    M-53 went from

    5500kg/8800kg to 6600kg/9700kg

    weight 1515kg

    length 5 meters

    diameter was about 1020mm

    So the M53 was shorter, thinner, lighter, and more powerful in dry thrust.

    Also, they are quite different engines when it comes to bypass ratio, with different advantages and disadvantages.

    Maybe a “Second Falklands War” thread should be opened for all of this?

    Disheartening, isn’t it?

    It’s amazing that some people haven’t even the basic competency to be able to read their own language, and see the original post is a hypothetical based on a scenario of Argentina increasing their defence spending to a global average as a GDP percentage.

    Instead, the usual hot headed, comprehension-failure driven chest thumping comes into play in what is quite a simple question:

    How would you rebuild the Argentine Air Force given a 2 to 2,5% GDP defence budget….

    your ideas is quite clever and interesting.
    Flanker seems very logical choice.
    however the flanker and j-31 combination is interesting and I ask why those two?
    why not say flanker and pak-fa? (same supplier) or flanker and j-20.

    j-31 looks nice and tasty but big question is range.

    I’m trying to strike a balance between affordability, capability, and RCS.

    I’m envisaging the AEW painting the initial or overall picture, with the Su-30’s acting as a destroyer in it’s own right due to large radar capacity, AAM payload, and fuel load (with judicious use of IFR to extend this even more). But also, those Su-30’s sharing their information with more stealthy J31’s who are not required to use their own systems until show time. Sort of like a mini AWACS, shepherding it’s deadly chicks, but one that is lethal too.

    Hence the need for seamless information flow.
    A similar sized country in the Southern Hemisphere developed its own data link family, for example.

    I’m assuming the J-31 has range equal to the Mig 35 or late Mig-29 derivitives. (I’m not going on the obviously wrong wiki figures, but on size, engines, and intuition.)

    Not ideal, but better than the loaded Mirage III, Super Etendards, and Skyhawks used in 1982.
