    I wonder if it will be scrapped in Alang. They could use the money they’d get from dismantling another aircraft carrier.;)

    India has the MKI does it not?
    The MKI can do a wide range of A2G missions.
    Besides, we have not seen the FGFA layout yet..

    About the T-50 layout, India will have to make do with whatever Sukhoi see fit.
    Comprende?

    The MKI does a wide range of A2G missions… with Litening pods.

    Which would defeat the purpose in a stealth aircraft used for stealthy ground attack roles.

    Comprende?

    I think you are confused about what role the Pak-Fa is meant for..

    The Pak-Fa do not need such A2G sensor package as you try to smear all over it.

    Take a look at what other assets VVS has for A2G role, long range stand-off and all the way to CAS role.

    If you think the Pak-Fa will carry a big A2G targeting/sensor Pod, so be it.. i cant help you..

    And like I said and you ignored, I was referring to the requirements of virtually any customer the PAK FA will ever have outside of the VVS. India, for instance, doesn’t have Su-34s, Tu-22Ms and Tu-160s exclusively for the A2G role. All these other customers(one of which is financing 50 percent of the program) WILL want a multi-role stealth fighter that can be used in ground attack and deep penetration roles.

    If you can’t understand that I can’t help you.

    The Pak-Fa will get a penalty in Aerodynamic(in high Mach) if it were to field this big EOTS sensor.
    Its Pros and Cons.. as allways…

    Like i said, different role and requirements.

    A much lower penalty than carrying an external targeting pod.

    Hmm… Makes me half-wish the PAK FA began development 5 years later. That stuff sounds like the future of aircraft construction, not just for engine blades but major aerostructure components.

    I hope some benefits trickle down to the T-50’s overall stealth construction before it enters service(Say, RAM panels and skins, even wing and fin elements) but that’s probably being a little too optimistic about design changes…

    Oh, it gets better. These Russkies doing civilian research into MWNTs found them to be not only highly absorbent in HF radar waves (micro/X-band), but also “almost radio transparent for [the] low frequency region”. In other words true ‘broadband stealth’:

    I can’t believe Witcha posted in the PAK-FA thread and never once mentioned S-ducks!! :eek:- I think I need a lye down!……Maybe they should leave the T-50’s IRST as is- in order to give the opposition a fighting chance! 😉

    The last time I mentioned S-ducts on this thread was like two incarnations ago. Since when did I get grouped among the haters and naysayers?:confused:

    What, in desperate need for more sparring partners now that they’re growing thinner lately?;)

    There exist no evidence of the T-50 having storage for such large EOTS like sensor underneath its cockpit section. The only place for T-50 IRIST are above and infront of the cockpit canopy.

    The F-35 and Pak-Fa have different roles and different requirements. So its pointless to pull up these F-35 photos and say:

    Why don’t the Pak-Fa have this and that..

    1. The F-35 also has similarly stealthy housing for its IRST, the EO DAS.

    2. What, the PAK FA doesn’t need a stealthy internally fitted targeting system for ground attack roles? Even if the RuAF wants to operate it mainly in an air superiority role, the IAF would think otherwise.

    I’m looking for information on the Gripen’s Cobra HMDS. I haven’t been able to find much information on it besides the fact that it uses Denel Optronics’ optical tracking system(instead of the more common electromagnetic system).

    Does it have an ‘X-ray’ feature like the Typhoon’s HMSS? Or will it be more along the lines of the the TopOwl and Elbit DASH?

    Perhaps Mr. Witcha forgot about the last MAKS where they showcased the T-50’s IRST. The transparency was clearly gold treated. 🙂

    Oh, I remember that. What I’m talking about is not the coating but the shape. A faceted IRST>A spherical one.

    I realise the benefits of having X-ray vision but could the view actually cause the pilots problems being able to look at everything could seriously distract him?

    How does this system compare with the F-35’s?

    That’s some great stuff on the MWCTs!:dev2:

    But why limit the applications to the engine? That material sounds like it could potentially replace titanium in many aspects of the aircraft’s construction. Rather than simply being coated with RAM, the PAK FA would be MADE of it.:cool:

    Meanwhile, I’ve been looking at internal optical sights built for various Russian fixed-in aircraft.

    I’m very much surprised the PAK-FA does not have a stealthier faceted IRST and ground targeting system like the F-35’s EOTS. From the decades-old designs above, it’d be well within their capability to make something like this.

    Regarding the AAW hull…is there any independent confirmation, some export material perhaps, that the MFR is indeed an AESA?. The siting, and sizing, of those panels just look completely wrong for an AESA.

    Everyone else who can do AESA has latched on to the benefits of light weight and no waveguide dependencies to mount the antenna faces as high as possible…the benefits of such being so crucial and obvious as to not need explanation. You only mount panels low on the superstructure, as with the Chinese and SPY/Aegis designs, if you need to drive the panels from a high power source thats hard to mount high up i.e a passive phased array.

    Why do you go to the trouble of building an AESA then throw away some of the biggest benefits of the technology mounting it so low in your hull?.

    AESAs need not necessarily be compact and lightweight; see the Russian Gamma-DE. Or large air/missile defence radars like the Green Pine.

    It may be that the Chinese wanted a long-range, ABM-capable AESA and so increased the panel size and weight; also their hardware may simply not be as compact and light as Western counterparts; again, like the new Russian AESAs for the S-300/400 SAMs.

    In any case pretty much all publicly available literature on this dating several years back has been counting on it being an AESA, so I’m guessing it has an element of truth.:D

    Not nuclear subs, making the boat useless.

    What’s stopping it from docking conventional subs?

    That’s what happens when your country breaks apart, and your main southern shipyard and many of the ships in it are in one of the break-away parts.

    The Russian Navy still intends to base subs there, so if they’d just throw Ukraine a bone they could finish and use it.

    ^Already? Wasn’t it supposed to be going for a 5-year refit this year?
