    yes but my question was.. that Merlin above is not the same merlin in that picture. There’s a giant dish under the Italian Merlin and I’m asking if that dish replaced that giant bulb that extends through the butt.

    btw thanks for the picture of the Z-8 lowering its mini radar.

    They’re two different AEWC systems on the same platform. The Italian Navy one uses a larger radar an underbelly radome whereas the proposal for the Merlin with the ‘bulb’ is for the British Merlins which will replace the Royal Navy’s AEWC Sea Kings.

    China simply has nothing to sell at the moment with this capability.

    I’m sure there are plenty of surplus H-6 airframes that could be converted to tankers for the PAF’s needs. It’d be cheaper than a few surplus IL-78s anyway.

    where’s the radar?

    That little cylinder sticking to the back is it.:D

    Not even a AL-31FM1 engine upgrade?

    For some reason the IAF isn’t big on engine upgrades unless the original engine is at the end of its lifespan and needing replacement. The IL-76s haven’t been re-engined with PS90, the MiG-21s still retained their faulty old R25s even after upgrades, the MiG-27s were retired rather than re-engined, there seems to be no hurry to replace the Jaguars’ old Adour engines….:(

    But IMO they should at least go for the FM1s, if not the 117S. That’s supposed to be a lower-cost upgrade that simply replaces the engine core during overhaul.

    Does it really matter that they did not have their armament for a year after initial delivery? Not like they were in any sort of combat role at the time. IDK, seems kinda inconsequential in the greater scheme of things.

    Also, India had problems with crappy R-77s produced in middle of 90s. I don’t think today’s variants will have any problems.

    EDIT: Also, how many Su-30’s does HAL produce yearly? Al-31s? Some recent numbers would be nice.

    Last I read (years ago) it was 14 a year: the original 140 MKI production plan envisioned building 14 a year for 10 years or so; since then they’ve supposedly ramped it up a little, not sure of the numbers now.

    That said what’s going on at HAL Koraput is something I’d call ‘limited series production’ at best, because numbers are still coming along slowly and the IAF has had to order additional MKIs directly from Irkut.

    I find it quite difficult to believe.

    G550 huge range is accomplished only with a puny 900 kg payload.

    Any further kg put in payload would mean less fuel embarked and at the same very more deadweight.

    So G550 CAEW’s real range should fall well short of theoretical G550’s range, and I mean very short of it.

    And because AESA modules are quite heavy, I doubt those comformal arrays are fully packed with modules, I find it more likely the modules are spread with some space between them to exploit the surface available to gain some more angular resolution.

    Both payload and power supply limits make very unlikely those array are really that large

    Are you really comparing different generation electronics in relation to power absortion?

    I could ask you what has more computing power, your IPhone or my old P4 @3Ghz, equipped with a 7800GT videocard, several GByte of RAM and so on?

    Well, my old workstation require a good 420W, it’s a little bulkier than an IPhone and it’s not that fancy, but I believe can still hold his ground.

    What if I upgrade it (the case, I mean) switching to a Pentium i3 with all the bells and the whistles?

    Ok, it’s still a couple of years behind an IPhone, it’s still bulkier and far more power comsuming, but nonetheless it could provide some slighty better performance and capabilities than an IPhone.

    IAI/Elta quotes 10 hours endurance for the CAEW.

    http://www.defensenews.com/osd_story.php?sh=VSDF&i=3631889

    That’s still higher even when compared to the upgraded A-50 with the lighter onboard equipment(6 hours).

    With the Su-33 upgrade programme, has the Russian Navy given any thought to the old proposal of putting a balance beam radome on the Su-33KUB trainer for an AEW role?

    Seems like your wish has been granted, NDTV tweets that Govt might divest (at least a significant part of ) HAL.

    Interesting. But I wouldn’t expect anything to come of the proposal. HAL is probably the single most successful and profitable defence PSU.

    I’m not quite sure how useful it is for a state owned company with a monopoly to make huge profits if the customer for the goods / services sold is the state. Eg let’s imagine HAL makes huge monopoly-based profits assembling aircraft for the IAF. It follows that the Defence Ministry is paying a higher price than it needs to pay for the aircraft assembled by HAL. That is a bizarre way to run a defence contractor – there is zero incentive for the contractor to become more efficient.

    Consequently why delays are the norm rather than the exception for Indian defence R&D/manufacturing/upgrade projects despite decades of experience with the same.:D

    eg. Avadi Heavy Vehicles Factory is the one and only tank manufacture/assembly plant in India. Which means it currently handles
    -Manufacture of T-90 tanks
    -Manufacture of Arjun tanks
    -Upgrade of T-72 tanks

    all on its own. Not surprisingly
    -All 3 manufacturing/upgrade programmes are years behind schedule
    -It nevertheless makes a profit, because, delays be damned, there are no penalties of any sort and the army is going to buy them anyway.

    Likewise HAL manufactures/repairs/upgrades each and every aircraft in the IAF’s present and future inventory, ranging from gliders and trainer aircraft to helicopters, fighters and UAVs,

    I am going to take a wild guess and say Sukhoi made two bays instead of 1 for a reason. Like structural integrity.

    Maybe. But we can all dream of something better.;)

    Ghana orders two Airbus Military C295 aircraft

    The Ministry of Defence of the Republic of Ghana has signed a contract with Airbus Military for the acquisition of two C295 aircraft.

    The aircraft are to be delivered from the beginning of 2012. His Excellency Minister of Defence Lt Gen. JH Smith, said the C295 will enable the Air Force to move troops and other security agencies across the country and within the West African sub-region. The aircraft will also be used for medical evacuation, paratrooping, training and humanitarian operations including assistance to organizations such as National Disaster Management Organisation (NADMO) and the peace mission of the United Nations. The Ministry of Defence of the Republic of Ghana is a new Airbus Military customer.

    How much does a C-295 cost? I’d have thought poorer buyers like Ghana would prefer something like the Ukraininan An-72/74 instead…

    ………….Did you really expect internal Yakhont?

    Come on man…

    Well, an MKI can fit a Yakhont or even a Kh-59MK in the centreline pylon between its intakes…;)

    Seriously, I’d have preferred a single long bomb bay compartment(no divisions) with a number of internal hardpoints arranged such that if necessary the entire length could be used for a large missile or two. Not two smaller bays separated from each other with their own doors and hardpoints.

    Kh-38, Kh-58USHK, new Kab-250, Item K047 in development….just for starters.

    I’ve read about them. But they’re smaller or subsonic missiles with shorter range, less firepower and more susceptible to enemy air defences.:(

    a question for you my gothic friend..
    is the Chinese Il-76 contract still unresolved?

    what I thought happened was:
    China wanted Il-76
    Rosoboronexport says they can get it by so and so date
    Rosoboronexport then demands more money
    Tashkent plant which handles production demanded more money, has some production limitations too
    After this, production moves to another factory in Russia
    Problem solved? Da or Nyet?

    Nyet. Trident already covered it; Russia’s been offering the IL-478 for like two years now but the Chinese don’t seem interested. Unless the Y-20 runs into major problems it’s unlikely they’ll get an order.

    what are the chances that this aircraft is an attempt by China to build its own Il-76, like J-11 to Su-27?

    Very likely, given not only the physical similarities but also the fact that it appeared and gained momentum only after the failure of the Chinese IL-76 contract.
