    Or how many of those systems are actually in service. Most of those toys for the F-18 are only nominally in service. There are so few of them around that strategically they make no difference. How many towed decoys for the F-18 fleet have actually been procured?

    Zvezda TV today showed video of those 10 new Mi-8’s we talked about last month and they now have their FLIR balls installed.

    10 more are on order.

    The goszakaz website published a tender for new single piece canopy over a year ago if my memory isnt playing tricks. The current canopy will not be what we see on production machines.

    I was talking about the Ka-52. The pilot’s FLIR is gone, only the gunner’s FLIR is installed. On the prototypes there was a little GOES ball just for the pilot.

    The Ansat is in no way shape of form a “high end” helicopter. In the current production configuration it’s not kitted for night time or bad weather flight at all.

    More likely than not the Mistrals will get a bunch of lousy Ka-226’s actually and Im not kidding. Kamov is lobbying for some FLIR equipped Ka-226 model for the Mistrals.

    They got rid of the little GOES ball for the pilot — a retarded decision. What’s the point of buying a high end helicopter like this if you’re going to go all cheap on the optics package?

    Sukhoi has spent the last 10 years running around the planet setting up support facilities for the SSJ line that in tandem can do work on the Flanker line and that will end up handling work on T-50’s in the future should orders emerge. The Malaysian Su-30 deal saw the Indians getting some support work and pilot training work. Why? Because HAL is Sukhoi’s partner in that part of the world and sharing is caring. As India’s geo-political importance grows Sukhoi can use India power and HAL itself as leverage on India’s neighbors too. You have a huge 3-5 billion dollar Sukhoi complex going up in Malaysia itself that will support MS-21’s down the line too. Do you see Chinese aircraft makers moving capacity out of China to further export sales? Until you do, you wont see too many Chinese exports. Sukhoi is global. And it combines packages of civilian and military goodies to sweeten any deal.

    All the more credence to my assertion its optimized for transonic and low mach speeds. Unless they have some D-30 class engine on it, this is no high mach cruiser like the T-50 and F-22.

    The F-22 has done M1.7 without AB (though almost certainly with no weapons on board and with with probably half empty fuel stores). High mach numbers like that are just the 5th gen reality.

    “if T-50 is opitimized to live above M2 then why bother with the big surfaces. one big compound delta wing would surfice.”

    Because its a beast of burden meant to fill two rolls for a country that can no longer afford both a dedicated interceptor and a dog fighter.

    “btw, in these fighters, top mach # means very little by itself. push the engine out pass blade temp and you can up the mach. the point is how much drag you will get in turn and cruise and at what altitude.”

    That trick works for both sides. Lets pretend the F-22 has a max speed of M1.8 and the PAK-FA tops out at M2.2. Remove the safeties and you can push the F-22 probably to M2 and the PAK-FA maybe to M2.3, but the gap remains much the same.

    A max speed .3M better than the other guy is always a good thing to have.

    The supercruise ability of European 4.5 gens is basically BS and has little to do with their aerodynamics. The Su-35 supercruises too, but we still say its still optimized for transonic and low mach nose pointing — same goes for the Eurocanards. The reason the Eurocanards were supercruising 10 years sooner is simply because they had better engines available to them that much sooner. The basic Al-31 has been more than a bit dated since the early 90’s. It’s late 70’s engine tech and the Russians went the entire decade of the 1990’s without anything better.

    “How do you know ? Do you work at Shengdu ? “

    No need to. See page 16 of this thread. They open sourced their own studies on this intake design! You can read the conclusions the Chinese came to in English. Their own conclusion is it suffers no penalty in the .6-1 mach range, but at speeds over mach 1 there is a penalty with this intake design. It becomes rather serious at or around mach 1.5. Like the Flanker, this is a design optimized for nose pointing in the transonic or low mach sphere.

    The T-50 is as much a MiG-31 replacement as it is a Su-27 replacement. It is optimized for high mach performance. In fact, in the transonic zone its probably inferior to the J-20 because canards at those speeds will do a lot for you.

    Typhoon, Rafale and Gripen are not serious mach 2+ performers. The T-50 is built to live at or above mach 2, lots of sources out there cite the mach 2.2 number — including Russian state TV.

    16 or 17.

    9 series built and 7-8 pre-production models used for weapons and flight testing.

    http://www.flightglobal.com/articles/2010/12/29/351388/picture-tu-204sm-conducts-maiden-flight.html

    Tu-204SM first flight.

    3 Ka-52’s were also delivered yesterday. That should bring the total in VVS hands to 6.

    “Agreed, it has more supersonic potential with engine upgrades then either F-22/T-50, but i think thrust deficit will hold it back for a long time.”

    No way in hell is it a better high mach performer than the T-50. This is not even debatable. The Chinese paper I linked to discussing the DSI intakes on this things also discusses the sort of performance you should expect from this sort of design. It is optimized for transonic flight, hence the canards. At any speed over mach 1 you will see performance degradation thanks to the intake design they selected. The T-50 on the other hand is all but meant to be a high mach cruiser with absurd escape speeds. It’s intakes in no way shape or form hamper high mach performance, and it has no canards instilling a weight penalty and adding drag. All else equal, the T-50 will have a better top speed, and this is not debatable. In fact, all else equal the T-50 should have a significantly higher top speed than the F-22 too.

    As for superior stealth, I have to ask — based on what? The gigantic control surfaces or the utterly conventional rear? There is no eyeballing it. It might well be stealthier than the F-35 and the T-50, but anyone who claims with certainty like this to know is a lying SOB.

    It’s primarily a LO measure and if you want a transonic fighter it gives you a hell of a good one. In the .6-1 mach window the intake suffers no performance degradation, but at high mach there is a penalty for your LO gain. Nobody really knows the F-22’s true top speed. That little bit of info is still classified. The PAK-FA is supposedly meant to do Mach 2.2 without killing its engines, it could probably be pushed into the Mach 2.35 range of the old MiG-23 with all “safeties” removed, but for all we know that 2.2 number is BS.
