    ALARM compromised in Yugoslavia

    ALARM compromised in Yugoslavia

    The Air-Launched Anti-Radiation Missile (ALARM), the Royal Air Force's highly capable weapon for suppressing enemy air defences, has been compromised in Yugoslavia. That is the pessimistic conclusion that must be drawn from the fact that an almost completely intact example is now on display in the Belgrade Military Museum as reported in the May issue of Jane's Missiles and Rockets.

    According to one Yugoslavian source, the missile in question - fired during Operation 'Allied Force' last year - was found just outside the village of Nikinci in western Serbia. The ground in that region is considerably marshy, which may have contributed to the missile being found essentially intact.

    There are now questions of obvious concern to the Royal Air Force, NATO and the manufacturer, Matra BAE Dynamics:
    · Did the weapon fail to self-destruct and, if so, why?
    · How much have Yugoslav engineers been able to learn from from studying the recovered seeker head?

    ALARM was not a commercial success following its initial appearance in 1990, and only the UK and Saudi Arabia have procured it. However, it was designed a decade later than the equivalent US AGM-88 HARM and has shown itself to have several advantages over its US rival. According to one senior serving aircrew officer, US and German aircrew fired around 100 HARMs at a particular Yugoslavian target without success, and the Royal Air Force finally destroyed it with a single ALARM.

    Although at first sight this may seem unlikely, it is partly a function of tactics and partly a function of the different design philosophies of the two missiles. Yugoslavian sources report that defences are able to deploy Russian-developed emitting decoys designed to counter HARM, and that the netting of multiple emitters and passive sensors allows the target illumination time of a surface-to-air missile (SAM) battery to be reduced by between 50-70%.

    If the enemy shuts down quickly, HARM is unable to find its target. This leads commanders charged with the suppression of enemy air-defence (SEAD) mission to fire a steady stream of missiles (all effectively on a predictable, relatively short time-of-flight trajectory) in order to create a 'HARM umbrella'.

    A single ALARM can loiter at high altitude, remaining in the area of the emitter for some time. Since it was originally conceived primarily as a self-defence weapon for aircraft - some of which might not have a radar-warning receiver - all the 'intelligence' is on board the missile, making the weapon very flexible and difficult to spoof. This capacity of 'intelligent' loiter for corridor 'sanitisation' and SAM harassment tasks made ALARM the anti-radiation missile most feared by Yugoslav SAM crews.

    [font size="1" color="#FF0000"]LAST EDITED ON 28-05-01 AT 08:23 AM (GMT)[/font][p]Put the ALARM in continuous use for 10 years strait ( used several times a year in Iraq ) and let the enemy observe it for that amount of time, and then tell me how effective it will be. In a way the HARM has been compromised for years because everyone and their brother knows how it behaves. The ALARM hasn't been used to that level.

    RE: ALARM compromised in Yugoslavia

    When is the HARM going to be replaced??? How is it that the USAF/USN, the supposed "SEAD" experts can't replace the HARM? This missile is too old, slow, big and obviously outdated.

    BTW elp. How does July 6 sound for Wright PAtt?

    RE: ALARM compromised in Yugoslavia

    Who do you think, if ALARM has indeed been compromised, has had access to the technology by now? The Yugoslavs (obviously)? The Russians? The Chinese? The North Koreans? The Iraqis?

    Anyway, who cares? What I mean is how will this affect the operational use of the ALARM and the measures adopted to counter it?

    How will this effect things????
    One of the advantages the West has had when going into places like Iraq and Serbia is the fact that they are well trained against their opponents. The reason they are well trained is because they have real Mig-29s to fly against, and their developers have real SA-3,-6,-9,-13,-8 etc systems to test against. (Courtesy of Israel, Egypt, Germany, etc etc).
    It takes away a little uncertainty. Added to well supported operations, good C3I, and quite a bit of money it makes the job much easier. The other side getting their hands on your stuff means they can test the effectiveness of their current countermeasures and make changes to their operating procedures to ensure that when faced with ALARMs in the future there is less doubt. Of course the first thing the owners of the compromised technology usually do is update it to minimise the cost of the compromise. (ie this has happened with almost all Russian weapons and aircraft including the upgrade programme for the Mig-25 after Belenko defected, and the Mig-31 after its details were compromised by a spy.) Of course the developers of ARMs could also benefit as well.

    RE: ALARM compromised in Yugoslavia

    Wasn't it the Tacit Rainbow that was going to replace HARM? or am I getting it completely confused with some other missile?
