    Check your numbers. The F125 is rated at more than 9000 lbf of wet thrust, depending on sources (and variants I guess) up to 9500 lbf. Per engine of course.

    The F404 is very reliable, true. But not that economical.  This should come as no surprise considering its low bypass ratio.
    Compared to an R-25 turbojet, any modern turbofan is a fuel sipper.

    Hi Eagle, I think most turbofans for fighters of the 1970s had a low bypass-ratio. I have in mind F404, RD-33, RB199 and M53. I’m not sure if the F404 has  worse specific fuel consumption compared to the others? If I had to guess, I’d say that the M53, with its single shaft, is the engine with the disadvantage, we’d want to find the figures, though.

    Both the F-16 and F-35 also comply with the 800 metre requirement – the Norwegians demand it.

    without foundation and makeup

    Wrong thread. That’s a USAF F-22…:rolleyes:

    Impressive and funny (notice how both seating chairs on the balconies are gone in the 2nd image).

    The two different images may not have been taken at the same time or even on the same day.

    There seems to be talks about a new business option for the MiG-29s and 35, discussed in relation to Malaysia. Russia would get the currently inoperative MiG-29 and sell in exchange the -35 at a reduced price.

    This may in fact be quite interesting, if applied on a large scale:

    – The customer would benefit from reduced prices and make some use of their otherwise obsolete or inoperative fighters
    – MiG-35 would be sold easier than having to compete in equal terms with other competitors.
    – Russia could use the old MiGs in a variety of ways: first, doing a basic overhaul and selling them at air forces in need of almost anything flying for very friendly prices, almost for free or in exchange of other “currency”, be it economical or political, that can be of use. Given many of Russia’s allies are under extreme economic pressure, it is not hard to find countries which would be among the ones who would benefit the most: Syria, Serbia, Iran, Cuba, Venezuela all would benefit from having the MiG-29 in a reasonable state either to have some form of fighter force at all or to boost it accordingly to the increased threats. Second, they could be upgraded heavily and sold to India for instance in order to boost their number of operational squadrons.

    They would not make trillions but would load their repair factories, get business for the MiG-35, keep customers and get further profits through the maintenance of an expanded MiG fleet. Maybe it works, who knows.

    There have been also comments that the contract with Egypt for the MiG-29M was finally closed at this year’s MAKS.

    Malaysia are going to buy MiG-35s? I thought they were buying Kuwaiti AF F/A-18s second-hand?

    Put any limitation one could imagine but the idea of deploying chutes BEFORE touching ground is just pure GENIUS!:applause::applause::applause::applause::applause:
    Or almost of capacity of thinking out of the box…:rolleyes:

    Planes have been deploying their parachutes before touchdown for years – it’s not a recommended procedure – see how hard he touched down.

    STOL performance, proven

    Or maybe the aircraft was just very light, little internal fuel? Impressive none the less…

    Indian Air Force Freezes Jaguar Engine Upgrade

    http://www.defense-aerospace.com/articles-view/release/3/205300/india-cancels-jaguar-engine-upgrade.html

    PS I note that the headline says it’s definite while the quoted text says it’s likely the engine upgrade will be frozen.

    Hardly a surprise. The IAF would be leaving it a bit too late by now, seeing as their Jaguars are due to be retired in less than ten years time. Very few air forces change the engines on their old airframes for a new type of engine – usually not worth it.

    How are they rapidly relocating ? IOW, is this because of some recent technological advancement ? I say this because, most SAMs do not carry enough fuel to change their location, frequently in order to engage the target.

    I think he is referring to their launchers and not the missiles themselves. Many Air Defence systems are mounted on vehicles these days, especially the shorter-ranged systems.

    MiG-23 early modifications had insufficient maneuverability. MiG-23ML and later one of the best fighters in its class

    The quote from the Polish book is not mine, the name of this book is unknown to me

    Polish book? Probably by Piotr Bukowski.

    Can someone explained to me why MIg-23 is often seen as a failure unlike Mig-21 or Mig-29

    Not really considered a complete failure. Most of those countries which received aircraft from the Soviet Union were short of cash after the Cold War. They could barely afford to operate the MiG-21 – never mind the much more complex and high-powered MiG-23 – the ’23’ had to go…

    MiG-23 early modifications had insufficient maneuverability. MiG-23ML and later one of the best fighters in its class

    That’s wrong. I don’t think anyone was really complaining about the MiG-23’s turning ability – it was hardly any worse than that of an F-4 – and whatever improvements were made to its maneuverability in later versions it was still not the ‘best in class’.

    This factor was also pointed out by Yugoslavian pilotos who evaluated MiG-29, F-16 and Mirage 2000.

    When did Yugoslav pilots get to fly the F-16 and Mirage 2000?

    The general consensus from Luftwaffe and USAF pilots who flew ex East German MiG-29s was that while the helmet mounted sights and and R-73 SRAAM were certainly impressive, the found the radar less impressive and the IRST not really worth having.

    I love these arguments.
    Not one iota of information on the public domain on how these systems would fare against each other… But one and a half pages and we are already on industrial fisheries!
    Can we stop the thread? There’s no available information in order to make any meaningful insight. The end.

    I have to agree. They have really ruined this forum – they haven’t a clue what they are talking about, I’d say.

    Another Indian Air Force Flanker bites the dust…

    An Indian Air Force fighter jet crashed Thursday night in Assam. The air force jet that crashed was a Sukhoi Su-30. The Su-30 MKI fighter jet was on a routine training mission when it crashed in the paddy field in the Milanpur area and burst into flames at around 8:30 pm.

    The two pilots flying the fighter safely ejected from the jet and were rescued. One of the pilots suffered injury in his leg, defence spokesperson Lt Col Harsh Wardhan Pande said.

    A Court of Inquiry will investigate the cause of the crash, the Indian Air Force said.

    Islamic Republic of Iran Air Force F-4E crashed into the sea last week.

    The Iranian fighter jet crashed after a technical malfunction. Both pilots ejected safely.
