    Iraq’s integrated air defense network was decent, but not that great. It was built by the french in mid 80s, with all the work being done by 1986. While capable, it had two major defficiencies. Although integrated, it was integrated in such a way that low level radar systems and command posts coulnd’t talk to each other. It was very centralized and everything had to go through highest command first, and its speculated that was due to Saddams fear of giving his forces too much freedom. Basically, there was the main command post and four more regional command posts. Once those were destroyed, the rest of the network was headless and far from integrated. Second defficiency, in light of massive coalition attack, is that it never was designed to counter such huge force. It was built to counter neighboring forces, mainly Isreal’s and Iran’s. It was speculated that it could track and coordinate attacks on no more than 100 enemy aircraft at one time.

    As for downed coalition planes, there were some 40 of them, though most of them were downed by AAA and short ranged IR sams while they were doing low level flights. http://www.rjlee.org/aaloss.html

    Did i get this right – one will have to pay 300 dollars plus 100-150 more in taxes to fly two 5-6 hour legs, for a total travel time of probably not under 12 hours, cramped as hell with the rest of the sardines?

    While i approve of the low cost long haul idea, for such level of discomfort and travel time price of over 400 dollars is ridiculously high. Unless they somehow manage to cut that at least in half, I don’t think I’d ever fly them.

    Intrepid also seems to have turned their previously announced LoI for 20 330-200F into a firm order.

    A bit off topic, but do you happen to know what all the various hardpoints on the JH-7A are stressed for?

    Well, judging by the various pics, it’s like this:

    centerline pylon has been seen with 1.400 liter tank, which should be over 1.2 tons. Some claim they’ve seen pics with 6 250 kg cluster bombs on centerline pylon as well. So that’s over 1.5 tons. Like Crobato said, innermost pylon has been seen with 6 250 kg bombs, though the middle plyon i’ve seen with only 4 250 kg bombs, not 6. Outer pylon has been seen with 250 kg bomb, and wingtip one, like is said, can hold at least small AAMs. All in all, 7 tons seems like the very least it can carry, with 7.5 tons being likely as well. What would be interesting to know is internal fuel…

    You yourself have been tricked with comparing apples and oranges. Jolly rogers link mentions radar power being rated at some 10 kW. Something being rated at certain value means it has been certified up to that value, for its maximum output. Be it radar, engine, etc. So that value is peak power. And you compared it with average power for the zaslon radar.
    Furthermode, just what kind of average power are we speaking of? Yes, one could just give out an approximate average power of a radar. But usually such data is given for various modes: average power in pulse mode, average power in pulse doppler mode, in CW illumination, etc. Here too its important to know just which kind of apples are we comparing to which kind of apples.

    Then there’s the wavelength. Though probably similar, there still might be differences enough to make them important enough for us to consider the wavelength factor into our problem. Finally, what about signal processing? That category is hardest to determine, though one could assume that promo numbers were given upon the results of test done in perfect conditions – with as little background and ambient noise as possible. Still, even if similar in test conditions, singal processing abilities are sure to be different in real world scenarios, perhaps vastly so, enough that we should consider them when thinking of this problem.

    So, is there any info on just how configurable MALD is? Can it change its RCS in flight? (i’m guessing no, as that’d require significat flight characteristics degradation) What sort of RCS ranges does it cover when looked at certain angles?

    Also, how effective would it be (or any small decoy, for that matter) in light of ever increasing effectiveness of SAR modes on radars? I guess fighter based ones don’t have the power to do long range SAR of acceptable quality against such targets, but land based radars should be able to do provide a detailed enough image of the decoy from a hundred or two of kms away so it can be assesed whether it, in fact, is a decoy, or a real plane.

    Is this apron made from metallic panels? If so, why?

    Hmm, i guess for some reason they can’t use just bare ground (weird, knowing its mig23, which is pretty good at operating from improvized airfields) so, since they have to have some hard surface, they would rather use metallic panels, which are easy to replace in case of attack and damage to the apron, than asphalt, which might take a while to repair…

    I’d just like to point out that if the mentioned game of chess between US and China ever turns to war, there is no guarantee that chinese with overwhelm US, aicraft numbers wise. I guess it depends on the support US may or may not get from countries like South Korea/Japan/etc, which would offer bases from which USAF could operate. With such bases, total number of US planes could very well match chinese.

    Even in the worst case scenario, where US would use just guam, okinawa and carriers, starting balance of power would not be so terrible, 400-450 US fighters vs 1200-1500 Chinese ones. Within first 24 hours of hostilities, we’d see a big change in that ratio.

    Guys, (pls correct me if I am wrong) the Cluster Bomb fitted to the J-10 is 250kg?? If so, at least weight-wise there shouldn’t be a problem carrying the PL-12??

    Weight wise, no, there shouldn’t be a problem. But length wise would be, i’m afraid impossible. That cluster bomb does probably not exceed 2 m in length, while pl-12 is almost double that. With the landing gear behind it and important uninterrupted air flow space for the engine in front of it, i don’t know how a pl-12 could be fitted there.

    Close to zero. Though I’m sure Boeing would love it if it could patent basic aerodynamic shapes. Commercial airliners look very much alike too and yet they’re all very unique. I wouldn’t be surprised if future russian/chinese UCAVs end up looking similar as well.

    If its possible to combine semiactive with IR/IIR, likw in sm-2 IIIb, then it’s certainly possible to use ARH instead of SARH and combine those two modes of guidance. One could, theoretically, put a IIR seeker on the very tip of the missile, with a ring of T/R modules around it, which would form an ARH seeker. Only issue i see here is reliability of IIR at such huge speeds, where air friction and temperatures are immense.

    in reply to: USAF to retire AGM-129 #1802596

    I guess the fact they’re retiring them tells you it’s impossible (or not cost effective) to convert them to conventional warheads. I know, it sounds weird, but what other reason could there be? Perhaps the missiles themselves, because of the stealth or whatever reason, need constant pricey maintenance work – which would also be a good reason to retire them.

    Also, one must not forget that jassm is being developed in long range and ultra long range versions – over 1000 km. It would surely be much cheaper to maintain and would offer greater commonality with rest of the USAF. I am sure if the need arises, new nukes will be added to the inventory, but such threats do not rise overnight.

    That’s a sketch made by whom? Something eevn remotely official or a fan’s drawing? 78 meters seems a bit too long… unless they’re planning to put a helo hangar on that thing, which the sketch doesn’t show. Though, there’s really little need for a helo hangar on such boats, for croatian sea and missions croatian navy/coast guard might do.

    Helos being vulnerable is nothing new. For a short while in vietnam they were looked upon as good weapons platform but before war’s end it became clear using them that way will get a lot of them killed. And ever since then i’ve been hearing defense analysts saying helos are just too vulnerable to be on the front line.

    Sure, in some cases they prove to be really good, like the desert storm – where they saw enemies kms away, and where enmies were already disorganized and technologically inferior. Basically it was apaches mopping up.

    But on a real front line, where the enemy has a working battlefield AAW systems – there is just no way to win unschated. Especially if we’re talking about hills, woods or, god forbid, urban areas. Longbow’s radar won’t detect the threat hidden between trees or cars or buildings before its too late.

    I believe they’re too costly for what they offer. High flying recon uavs datalinked to guided artillery sounds like a better deal.

    No one took into account the matter of cost and availability. Even if tomcat airframe was brand new (and it can’t be, as restarting the production line would be way too costly) it’d still be costlier to maintain, and it’d offer perhaps half the sortie rate of a superhornet. That is, effectively, over a long term period, 2 superhornets in the air for every tomcat. Granted, for a short time surge of a limited size force, tomcat does offer a better platform (with same avionics) thanks mainly from its size, but at quite a cost.

    In light of political situation in the world, retiring tomcat was absolutely justified. Also, swing wings are thing of a past. Today’s aerofoils and lift augumentation devices at low speeds make them unnecesarry. I doubt we will ever see them used again.
