    Well, hopefully I am wrong. As you may know, silent attack with the AN/ALR-94, on the F-22 and lesser (not so bad) systems on Block II Super Hornet and the F-35 are the way AMRAAM shots will be cued for launch when the target emits.

    http://www.f-16.net/f-16_forum_viewtopic-t-9268-start-0.html

    HOBS/helmet cued dog-fight missiles, newer BVR AMRAAMS, on the Block II of the Super for example are good things. Yet look at how the U.S. Navy went out and got the LM composite IRST/centerline drop tank order.

    http://www.boeing.com/news/releases/2007/q3/070702a_nr.html

    These will be sensor-fused to the Super Block II. I think when you team all that up with an optical terminal seeker on an AMRAAM body, you just upped the self-defense ability of the aircraft significantly. It still won’t be able to run much but it may be able to give out more hurt.

    Have a good new year AD– Eric

    Yep, all that stuff will definitely help the Super and other aircraft no doubt. I think you are still undervaluing the off-board targetting capabilities that the US maintains and will improve in future years. They are going to be increasingly important as LO aircraft begin to proliferate. The tiny on-board FCR is going to be increasingly irrelevant IMHO.

    Radar based targetting is and will seemingly remain the main targetting system. New generation BVR air to air missiles such as Mica RF, Meteor, JDRADM and Sino/Russian weapons are still active radar guided variants.

    Most are still trying to catch up to what AMRAAM can already do, too and AMRAAM isn’t standing still.

    Anyhoo, have a good new year mate. Looking forward to seeing the defence news, for what should be a fairly interesting year in Australia at least…

    (KC-30A, Super Hornet, Wedgetail, JASSM all reaching IOC…)

    We’ll see Super Hornet et al at Pitch Black and perhaps overseas (Bersama Padu, Red Flag etc) and we may even see some serious decisions Government is due to make (MH-60R/NFH-90 etc, JSF Phase 1 contract etc).

    Cheers,

    While nothing is perfect, the chances of using a flare to decoy a modern IIR seeker is slim to none. The seeker technology and techniques are just too different from the older scanning-type of seeker.

    Flares were used to provide a secondary heat source to follow that might throw off the seeker. Modern IIR seekers do not look for simply a heat source, but the entire field of view as an infrared image. Flares would just show up as hot dots falling away from the fighter. The image of the target fighter will not be blocked or obfuscated by the use of any flare.

    See this early (10 years ago) use of the Aim-9x Blk1 against 4 aerial targets where several of them used flares to try and decoy the 9x. In each instance not only were they not decoyed, but they made direct impacts with the target QF-4.

    http://www.youtube.com/watch?v=4g4_jzqBJnA

    Fair enough, but that says nothing against my original point and that is that this is little more than the game of weapons v armour.

    I have a significant doubt that the QF-4’s CMDS systems have the benefit of the same level of technological achievement as the weapon being tested in those videos.

    Again, CMDS are still the most popular self-defence system in the world, even on the most modern platforms. I have no doubt there are reasons for this and it is not soley to defend against legacy seeker threats. Even if those reasons aren’t publicly broadcast…

    HOJ is sort of OK for older jamming but it is a last ditch effort in the terminal phase.

    Digital jammers and–even better if you have cross-eyed jamming and I doubt you will get the PK out of the AMRAAM HOJ-mode or no–or any radar homer that you would like.

    Adding any L.O. to the front sector makes it even worse. We need a simple solution. That is an optical terminal seeker on the AMRAAM. That with the AMRAAMs data link–backed up by geo location in the F-22 (AN/ALR-94) and/or AESA will work fine.

    It will probably end up that way. Multiple-mode seeker systems are definitely the way of things in future years, but you IMHO are making the same mistake as Swerve made on the IR heater thread and automatically assume that one side is remaining static whilst the threat advances.

    They don’t and if you think the HOJ capability hasn’t improved since it was introduced on the -B model AMRAAM then I would suggest you are being just a tad myopic…

    That link says that the flares are

    This technique refers to the older IR missiles such as Aim-9L/M and all current IR MANPADS and IR SAMs that are not using the new IIR seekers.

    That link points to their range of ‘Spectral’ flare. There are a variety of different types designed to address different threats shown by that manufacturer and no doubt others.

    I was simply pointing out that making blanket statements about what various decoys can and can’t do, seems a tad limited to me. These types of systems continue to be operated by modern forces that have a very good understanding of the capabilities of modern IIR guided weapons often operating them, themselves and facing similar systems as reference threats.

    I would just advise a little bit of caution in making such blanket statements. You certainly wouldn’t see operational planners making such sweeping statements…

    I wouldn’t expect a modern imaging IR seeker to take any notice of flares.

    I wouldn’t necessarily assume that IR decoy systems haven’t advanced in a similar manner to seeker heads.

    Some seem to think they have…

    Re: AMRAAM–If the target in question, doesn’t jam it out.

    Yeah. Because Home on Jam would be useless in such a scenario…

    Even the F/A-XX is more curvy, and it ventral structure is not planar, look much like the Pakfa…guess the Raptor is a more advanced concept..right?

    It’s fuselage isn’t particularly flat either. Guess F/A-XX ain’t LO afterall eh?

    got this in email communication from APA – Dr Carlo on J-20 posting in full

    Oh my god…

    Now all he needs is a couple of grainy photos to pronounce the end of the (western) world. He at least used “hi-res” photos when “assessing” the F-35…

    That leaves Meteor, but it’s going to be bought in large numbers by several countries, & we have the biggest share IIRC. Ditching it in favour of more AIM-120 seems like cutting our own throats.

    Boeing is looking at integrating Meteor onto the Shornet…

    These are in service with the Nimrod, which is now leaving service. Whether we will continue to have Harpoon in service is uncertain.

    They’d work alright on the Super Hornets though…

    4. AIM-120 & some dumb bombs certainly. Not sure what else.

    Harpoon anti-ship missiles?

    It isn’t totally different. It is an enlarged version with few refinements but generally sharing the basic layout. I’d say that the difference is roughly the same as between Rafale A and Rafale C, MiG-29 and MiG-29M or Su-27 and Su-35. Are these all “completely new aircraft”? It’s questionable…

    F/A-18E/F Super Hornets feature an enlarged fuselage, new larger span wing, new air intakes, new nose with increased electrical and cooling ‘through-put’, a new radar, new engines and considerably new avionics, EW systems.

    Compared to those other upgrade programs, there’s a significant difference. The Super Hornet in reality is largely a new design compared to the legacy Hornets, sharing only some basic configuration similarities and some avionics systems.

    $1320 mn + 428mn = 1748 mn.
    $1748 mn/24 = $72.8 mn.

    The Australian F-18Fs therefore cost $72.8m each, including support for the engines. There may also be some FMS costs, but I doubt they’d add a great deal to the unit cost.

    The rest of the price paid by Australia (over US$100 mn total unit price) must be attributable to the training, spares, & support package for the aircraft.

    You are including support costs and guesstimating how many spare engines were bought. I ‘believe’ Australia acquired 54x engines in total to provide an attrition/test and line replacement pool capacity but I haven’t seen that confirmed anywhere however irrespective of that, extra engines must clearly be considered ‘extra’ to the unitary cost of ‘a’ fighter.

    I am not. It is quite clear from many different contracts that a GEF414-400 costs $4m a pop, without support/logistics packages.

    Now I consider it rather pointless discussing ‘support costs’ because they are never apples to apples comparisons and can only be reasonably discussed and narrowed down, when the particulars are revealed.

    We are also assuming that the ‘contract modification’ announcement is the only funding dedicated to the production of F/A-18F aircraft for Australia AND that that contract doesn’t include the production of any supporting equipment by Boeing. It doesn’t seem to but without seeing the contract and noting the ‘deliverables’ how can one say for certain?

    A rule of thumb I generally stick to, is that production costs run at about 70% of an Australian defense contract with support (as a whole) making up the remaining 30%, as stated by Dr Stephen Gumley.

    If you accept that then you must accept the Super Hornets have cost Australia about $65m each more or less, minus any supporting, training, weapons etc…

    Edit- In my original post, I meant $8m per aircraft (obviously 2x engines per aircraft)…

    Flyaway Unit cost of F-18 is around US$ 50-60 million dollars and it is difficult to believe that the figure of US$ 115 million will not include spare parts support.
    The flying cost includes things like fuel, lubricants, man hours for maintenance apart from spare parts etc.
    I was talking about cost of spare parts only excluding lubricants, man hours for maintenance apart from spare parts etc.
    I read somewhere that Australian contract included spares for 10 years but cannot locate the link for now.

    The “modification” to the existing Boeing F/A-18E/F Super Hornet production contract (ie: to add the 24x Supers for Australia) was $1,319 574 240 (ie: $1.31b).

    This gives a unit cost of roughly $54m per airframe.

    http://www.deagel.com/news/Boeing-Awarded-Australian-FA-18F-Production-Contract_n000002792.aspx

    The contract for the GE F414 engined for this purchase was $428m which includes an initial 2 year support package and a 10 year PBL program.

    http://www.deagel.com/news/Australia-FA-18F-Engine-Contract_n000001742.aspx

    Therefore if you simply divide the project costs by the number of aircraft and consider each aircraft has 2x engines you get a unitary cost of $8m per engine. Now this is wrong, because it doesn’t include the support package or PBL contract, but even so, adding the airframe and engine unitary costs, shows that Australia payed less than $65m per aircraft.

    Not a bad price considering the capability being delivered…

    Maybe it will be the “silver bullet” capable of doing anything, i just want to hear what some more unbiased users will say. Some northern european countries that don’t build their own aircrafts will also get it and soon they will be out in exercizes and it will be interesting.

    EDIT: Oh, my reserves about the effective range that AMRAAMs will be used in REAL war (not exercizes), remain also for the F22. Of course if the opponent is very weak, it won’t make too much difference. Old tech aircraft radars for example will probably be jammed to death with USAF’s massive jamming power.

    1. Do you honestly believe exercises actually tell you much about the capability of an aircraft? If so, then WHY do they have “wartime modes” of all relevant sensors, EW and weapons?

    2. I hardly think AMRAAM is the only weapon system that suffers such an issue. Combat ID is required before ANY weapons launch. Meteor/R-77 etc are going to suffer JUST as much unless some sort of “weapons free” declaration is made and who can honestly see that happening in this day and age?
