    define 5th gen engine?

    E jet, with its simple architecture, is an excellent high speed high altitude engine. Otherwise, lack of inlet guided vane (variable geometry) make of it a “single task” oriented engine.

    Variable cycle engines do the complexity at the engine level rather than the intake level.

    MWF powered by a bigger motor makes more sense. Basically they are planning to make aircraft akin to Boeing P.3 Buffalo when their main rivalry is building a force of Focke Wulf Fw 190.

    Apparently the Mk2 gained canards.

    What is the engine in development, F424? M88-4? Kaveri 2.0? EJ220?

    They need to quit dicking around with pie in the sky and use COTS now. Play time comes much later.

    Teer-

    I’m skeptical of your chart. If the Mk2 is 1,000 kg lighter than Gripen NG then they’ve pulled magic. Growing 1.5 meters only adds 500kg. Magic. And at the length you posted they may as well substitute F110 for F414. If they are overtly concerned with price they would go P&W. Any of the three engines are a leap forward from Al-31F1.

    I would have loved to see twin F125 in the 11,000 lb st range, which is well within growth from Honeywell’s 2010 software-updated production variant. F125 has been run conservatively. Two are comparable to F414 singles and would be easier for field crews to swap. Ease of handling swaps is vastly under-rated, which is one reason MiG-19 remained so popular for so long.

    Teej-

    I don’t think you gave a fair comparison between Gripen and Tejas. Obvious stuff like pylon count substituting an argument concerning range is ignoring the obvious. Tejas is a lightweight fighter relabeled as a medium. Its internal fuel tank squarely leaves it in the light category, regardless of carrying external fuel. The drag index will eat up any significant fuel gains underwing due to their choices for being an overly short design like you would expect out of a light fighter. And marketing garbage doesn’t alter takeoff distance while carrying its big tanks creates a dangerous combination of overweight, underpowered, and too little control surface while operating from its intended deployment points with a significant bomb load. Tejas will be kept light or suffer in obvious ways. Then you compare the RWR and SPJ between the two as equal. Thales and Saab subcontractors have Cadillac systems compared to secondhand export models being proposed for Tejas. It reminds me of the bogus invulnerability of Bison with their internal SPJ in international exercises. Elderly F-16 or unproven JF-17 technology is being claimed to have done one in. (I still believe it was a SAM, but none of us will get the truth for decades.) The Tejas will get a slightly better generation compared to the Bison’s, but its doubtful it will perform any better. You brought up the small ground footprint and its mobility as being some sort of standard. Not at all. And currently Tejas has a slim if not non-existent supply chain that has ti be established. Not comparable at all.

    Austin, you’ve been around and know enough to know Gripen NG is nothing like Tejas MkII.

    Gripen NG will be better in RCS, it has better sensors (especially in radar and RWR), has an integrated IRST, has a better SPJ, and has a significant range advantage. It also has a well organized ground footprint that may be mobilized, has a chain of supply for spare parts, and has some of the best addons for specialized roles (i.e. reconnaissance) available on the market. And while Tejas supports quite a few weapons through its translator, the Gripen has unparalleled support for off the shelf systems on the worldwide market. So the Tejas MkII is not like a Gripen NG.

    Do the simple math. It is not rocket science to extrapolate fuel burn across a fleet assuming 100% availability rate. They are taking light fighters and replacing them with much heavier burn rates (and in reality we are ignoring what should be a sharply better availability rates) you see a major scaling of necessary fuel potential. Logistics are everything.

    Tejas is a nice design for the 1990s. I’d of thought by now they could have created something new for Tejas Mk2 beyond triplanes. By now I expected something evolved/advanced with at a minimum incremental improvements in RCS.

    If you scale fuel against fleet numbers both the PLAAF and PLAN have grown considerably over the last two decades and continue to scale over the next. China is oil dependent yet see no issue with growing usage beyond imports growth. Further add their domestic consumption growth. They have an unavoidable problem. Their only hope is too get Western countries to scale back consumption… which explains their carbon agenda support.

    They do not have fuel logistics to sustain that many active units unless they scale down to a majority J-10 fleet.

    The PLAAF has overstretched its food chain since its origins. Old habits die hard.

    I predict breakthroughs in sound dampening will find the way into next generation of engines.

    I cannot help but think L-15/JL-10 will be the lead in for J-20. Both have the look of being modern.

    J-10 really hits me as being a short timer. They needed numbers to retire J-8II, but its role is quickly reaching end of life as China has to pare down programs to fit their current economy.
