    It was faster than F100..but not extremely fast.

    It was extremely fast for it’s time.

    It was the first mach 2 fighter in service.

    Interestingly, the air force of Ecuador now operates both the J-79 Kfir C10 and the ATAR 9K50 Cheetah C.

    Be nice to know what their impressions are.

    Noticeable below is the longer Cheetah C fuselage (cockpit in front of air intake) and it’s neater air refueling probe.

    F-104 has fully laden 733 kg/m2 wingloading.

    http://en.wikipedia.org/wiki/Lockheed_F-104_Starfighter

    How could that possibly go into dogfight ?

    As Levsha has pointed out, it wasn’t designed to be a dogfighter.

    Korea saw pilots ask for more speed and a better climb rate.

    This the F-104 provided.

    It would have been used in slash and dash attacks, trading altitude for speed, and speed for altitude, and repeat.

    It’s design points entirely toward that.

    Time and hindsight has shown the Mirage III to be a better all round, balanced design, but the F-104 was designed to a set goal.

    A very debatable call. I’ll stick with the Kfir. J79 bestows greater wet thrust (17900lb v 15873lb) higher speed (1516mph v 1460mph) and greater weapons load. Not at all sur on the range, but the Kfir’s combat rad of 477nm is not too bad. But again, a very worthy debate. Maybe a new thread should be started?

    It is debatable I suppose.

    Just that the J-79 in the Mirage III airframe as the Kfir was not, initially anyway, a match made in heaven. Fatter, heavier, and needed extensive revising of the cooling situation, not the least of which was additional scoops.

    Certainly initially, there were performance losses, with some Israeli pilots lamenting it’s performance compared to their Mirage C’s and Neshers with the lower powered ATAR 09C. It is worth pointing out that the later ATAR 9K50 and J-79 have pretty much the same twr.

    When looking at an engine for the Kfir, the ATAR 9K50, Spey, and J-79 were all considered.

    The J-79 won out primarily due to maintenance and spares inventory, as the F-4 Phantom was used in large numbers by Israel, and military credits could also be availed of.

    Cheetah C and Kfir both have a similar theoretical max load too, although to emphasise, it is theoretical.

    In only mem, only one was made. Do I am right ?

    One Cheetah D twin seater was converted with the SMR-95 (modified RD-33), and a single seater Mirage F1AZ was also converted.

    Apparently, the Cheetah showed the most gains equipped with the engine, with the Mirage F1AZ showing a lesser performance gain.

    Are those V3B or Magic?

    They wouldn’t be Magics, as they were long gone by 1992, as far as I know.

    As far as I can tell, the Magic was last fired in anger in 1987, where one was launched by a Mirage F1CZ against a Mig-23.

    I think by 1988 they were taken out of service, but I stand under correction.

    Nice shot of an F1AZ with 14 bombs and 2 AAM’s.
    Note the antennae as part of the RIMS system.

    Did any IIIs ever get an M53? Or RD33?

    The ultimate Mirage III mod!

    Due to engine integration/cooling/drag…

    …this probably is.

    Pakistan.

    How are Pakistan currently finding the two aircraft, performance wise?;)

    I thought this was the best place for this, seeing as it involves the F1 and a Mirage III development.

    http://www.saairforce.co.za/forum/viewtopic.php?f=2&t=6042

    An interesting discussion on the programme to update the Mirage F1 is SAAF service.

    Both the F1AZ and CZ were to get the same cockpit layout, avionics, and radar as the Cheetah C in a new nose.

    Other modifications were looked at too, such as either a dorsal hump, or tail fin base fairing ala the F-16.

    Later, aspects of the cockpit upgrade found their way onto the Spanish F1 upgrade.

    Thanks for the info. Kinda sad to see what has become of the SAAF in the last 17 years or so…….

    They are operating on a much reduced budget, much like many airforces worldwide.

    Still, South Africa spends considerably less than the global average on defence, as a proportion of GDP.

    That is the big factor that will need to change.

    On the local BVRAAM:

    In addition to the A-Darter, the company has a project to develop a new radar-guided, beyond-visual-range AAM (BVRAAM), currently known as the B-Darter. This will be based on ten years of investment since the deployment of South Africa’s last indigenous BVRAAM, the V4.

    Central to this project has been the development of powerful radar technology compact enough to fit into the airframe of a BVRAAM. (Denel Dynamics has confirmed that this technology will be directly employed for the seeker head of the radar-guided version of the Umkhonto.)

    “We are ready to produce a BVRAAM demonstrator,” affirms Wilson. “But we need an investment partner for full-scale industrial development, like on the A-Darter. At home, we need government support and a user requirement from the SAAF.”

    The proposed B-Darter would probably have a maximum range greater than 80 km. “Our target is to be in the middle of the market –medium range and medium cost,” she asserts.

    http://www.engineeringnews.co.za/article/south-african-missile-company-provides-sandf-and-friendly-countries-with-force-multipliers-2011-08-26

    It’s called B-Darter, and it looks like it will share a radar seeker, or rather the technology, that was developed for the Radar Umkhonto ER. Even recently, it was mentioned that it may yet be a ramjet.
    Then of course, it may just look similar to the Umkhonto R, of which there are pictures out there.

    This deployment has highlighted the need for a lifter better than the C-130.
    This was the original force behind selecting the Airbus A400M.
    It needed to take a Rooivalk or an Oryx as a load, and deploy over a certain range without the need to refuel.

    This is why the recent Lockheed proposals for new C-130’s, or projects such as the EMBRAER KC390 are unlikely to succeed, certainly for that specified role.

    Recently, C-17 were offered, but unless the defence budget is increased properly, this will not happen.

    I suspect the A-400M will be back in the picture sooner or later.

    Do SAAF Grippens have BVR missiles?

    No.

    The R-Darter BVRAAM was retired along with the Cheetah C, although at one stage they were thinking of integrating it on the Gripen.

    The A-Darter is close to production, and Denel have stated recently that they have everything in place for a BVRAAM, just not the funding.

    I think they may be hoping Brazil hops on board with this BVRAAM as they did with A-Darter.

    So, it will be either the local BVRAAM, or Meteor.

    The fact that Meteor hasn’t been bought yet suggests they may be waiting to see whether another investor country steps in on their own BVRAAM.

    IRIS-T only? No a2g munitions?

    No idea.

    I can only see that they deployed with underwing tanks and the IRIS-T.

    The Il-76 and An-125 flights may of course be bringing those Paveways.

    The Gripen certainly wouldn’t self deploy with them.

    There are rumours also going around that a couple of Rooivalk combat helicopters are being deployed, although, as said earlier, there is no confirmation of this of yet.

    Bump.

    It appears South africa has deployed 4 Gripens armed with IRIS-T to the CAR region.
    They will be based in neighbouring Uganda or Zambia.

    There are also whispers that the Rooivalk is being deployed, but so far this cannot be confirmed.

    Certainly, Il-76 and An-125 flights have been ferrying equipment from SA to the region.

    This as a result of the attack on the paratroopers recently by rebels.

    Below are the 4 Gripens pictured in Northern Zambia from the last day or two. Looks like a twin seater and 3 single seaters.
