    Glenn, In modern practise instead of radars cuing IR systems, it is usually the other way around. A ship under threat maintains EMCON. Radars are powered up but do not radiate. Surveillance is performed by IR search devices (example Sirius). When a potential threat is detected, it cues the radar to radiate and provide high quality engagement tracks and fire control data.

    Totally understand that to remain in EMCON is obvious in a high threat situation, and if the IRST device is mounted fairly high up on the deck (better on the mast) of the ship then it would become the main passive means of detecting any ‘hot’ inbound missile prior to it activating it’s own seeker. Although if the difference in radar horizon and visual horizon is significant you might be taking a greater risk by letting the inbound missile slip that close before tracking it. However, if as you say, their heat signatures can be picked up beyond the visual horizon you have nothing to worry about. Problem is a great deal of the world’s navies don’t possess advanced IRST systems of the likes of SIRIUS yet. And have instead embarked on improving their radar systems, air/surface search and gun/missile FCR, to help deal with super-sonic sea-skimmers. To compensate for the sole use of the radar for detecting and tracking such missiles, advancements have been made to help control their emissions and reduce their probability of intercept.

    Great shots! Good to see a RNZAF Herc there as well. 🙂

    Ken – majic! http://www.click-smilies.de/sammlung0304/grinser/grinning-smiley-024.gif

    I look forward to the day when I can see it for myself.

    How much is the JSF F-35?

    I think $50 million is the current estimate. http://www.click-smilies.de/sammlung0304/fragend/confused-smiley-003.gif

    On the basis of this comment and plenty of others along the sames lines previously, it would appear the consensus is that Australia does not require top end defence equipment on the basis that no threat exists that will neccesitate it’s use.

    The defence of our nation is still important, I don’t see this ever changing. The threat that doesn’t exist, is the one the Kopp continues to manufacture out of near fantasy. He does this to try and justify the need for platforms that would be sheer overkill in the context of our strategic situation. We do need capable weapons, and we need enough of them, but within reason and within budgets, this has to be achieved.

    Assuming for a moment this is true, then what reason does any other country have to possess highly sophisticated defence equipment. Surely America is not going to be invaded by Canada. Surely France is safe from the Dutch. If immediate danger was a defining factor is defence capability requirements, no country could claim a need for the shiny toys.

    Again, national defence is a long-held accepted norm regardless of any perceived danger, or lack of it. History has taught many a valuable lesson about been prepared, and been able to effectively defend borders. Today’s friends could be tommorow’s foes. There are too many unknowns to risk not having a defence force. And if you look at defence budgets since the end of the cold war you’ll see that a lot of nations have been restructuring to fit the new reality, but they have NOT dismissed their forces as redundant.

    I really don’t why a civilian like Kopp has such a hard on for the F-111, he is hardly part of the National Secuirty Council, or the Air Force chief. He has to accept that they will eventually go, and while the current government continues to believe in a better alternative solution, they will go sooner than later. Does Kopp seem to think we are going to be plundered if they go? Get a grip on reality I say.http://www.click-smilies.de/sammlung0304/aetsch/cheeky-smiley-024.gif

    not trying to pick a bone with you, but i dont see the absolute truth coming out even if you were there to see it for yourself. if you have ever been in court or anywhere else where a number of participants are asked to independently describe a single event, then you would realise just how many ways a single event can be observed and described. the only way to accurately record an event is to record it with a camera, but even then you are only recording a small piece of a larger picture.

    This we actually agree on. 🙂

    Indeed even one person’s own experience is subjective and could be seen differently by someone else who was also there. Which, before the age of the camera, presents you with the problem of written recorded history. You might have one widely accepted version of events, but this version can be debated, and will always be debated by another party that has seen or interperated things differently. The Conundrum is, which version is to be believed? As no one version can ever be verified as the total truth if it were simply recored in writing by an observer/historian. You have to be very careful even with the camera too. Depsite been the marvellous invention it is, the entity taking the pictures can alter the perception on an event to make it look better or worse than it is, sometimes for political gain especially in war time, or for other reasons altogether. You could spend your entire life trying to find the real truth behind an event in History and just end up back at square one with more questions than answers.

    Plawolf,

    We are not going to see eye to eye on this, and I may have missed your point, but I have made mine. But that’s what these forums are about after all, debate and discussion. No one is ever going to accept everything all of the time. It is impossible to obtain a Holy Grail of absolute truth about historcial events, UNLESS you were actually there. I can live with that. http://www.click-smilies.de/sammlung0304/schlafen/sleeping-smiley-015.gif

    Something like a couple of DC-3s dropping paras? Be nice to see, but I have no idea.

    While this incident might be over rated by passenger accounts, I can’t help but feel this will be the way the first QANTAS plane will go down. There have been a few ‘near miss’ incidents in the last couple of years over the Australian skies.

    Well, the laws of physics cannot be repeal. Anything that travels at supersonic speeds will cause the skin of the vehicle to heat up excluding the engine signature. 20 years ago, electronics might not have been advanced and sensitive enough to detect at long ranges, but now, this method is the most common technique employed to detect and intercept very fast ashms.

    Provided you know where to look. If the IRST sensor is mounted lower than the mast-mounted air/surface search radar it will present you with a smaller visual horizon, as opposed to the radar horizon, assuming a sea-skimmer missile is inbound. Unless you can cue the IRST first with a radar fix of the incoming missile, how would you know where to direct your optronic based tracking device? If a sea-skimmer at Mach 2 gets within the visual horizon of the vessel before it is tracked, you will have VERY little time to react indeed. The radar is still very important, in fact, critical in the equation. And most naval SAMs are still radar guided weapons.

    The one you posted the above link to, analyst :p 🙂

    Sorry, thought so. Nice info there, and I really like the True Supersonics site you listed as a source. Some REALLY good pics of Russian missiles there.http://www.click-smilies.de/sammlung0304/grinser/grinning-smiley-003.gif

    …But perhaps you could also post a direct link to the source next time… 🙂

    I will do it now: http://personal.inet.fi/cool/foxfour/sovmis/sovmis-ssc.html

    BTW what do you think of my site?

    Which one?

    Ja, those pic of South African navy is great, but are they the most powerful navy in Africa?

    In my opinion, Egypt would be.
