Talk:Directional Infrared Counter Measures

From Wikipedia, the free encyclopedia

Sombody has put a lot of work into this page. But there is at least one clear error. I suspect there are multiple other errors as well. For example, I don't believe that the AAR-47 is accurate enough to provide cueing to a DIRCM. I've never heard of plans to make a DIRCM verision of the ALQ-157. I don't see how it would be possible to package an AAR-47 with an ALQ-157. Also, AAQ-144 should be ALQ-144...

And I'm pretty sure that the ALQ-144 is NOT the "main countermeasure for IR threats on the AC-130 Gunships"

[edit] DIRCM is not the right heading

I have to agree with the above. DIRCM is system sold by Northrop in the US and by BAE systems (now Selex) in the UK. The AN/AAQ-24 has a rotating turret that fires a laser at incoming missels. DIRCM is basically a US programme coming out of USSCOMS programme office.

It would be better if all these counter measures, warners and alike were grouped under the heading of Defensive Aids. A good portion (but by no mean all) of the airframers integrate these systems as part of a Defensive Aid Suite (DAS). This can often, but not exclusivly, supplement ESM. As radar warners can often form part of DAS systems. Apacheeng lead 14:28, 20 June 2006 (UTC)


[edit] DIRCM is the right heading heading

However, the pod produced by Northup Grummond and Selex is actually called the Nemesis Pod. DIRCM is a generic name for all Directed Infrared Countermeasure systems and is not specific to one in particular.

that is correct, but with the exception of the Nemesis System (ALQ-24), none of the other systems are DIRCM systems. That is, they are not "directed".

[edit] Alternate Title Suggestion...

Perhaps a better title would be "Random Collection of Mistruths About IRCM Systems".

Or perhaps, the title of the article is the only thing that is correct. This is classic:


"Modern missiles are now programmed to differentiate between thermal sources, such as the sun and ignore obviously powerful thermal blooms. As the DIRCM works it blinds the seeker apparatus by mimicking a large thermal signature such as the sun."

So let me get this staight, modern missiles are smart enough to ignore the sun... and DIRCM works by mimicking the... sun?

If the missile ignores the sun, making the target look like the sun seems like a good countermeasure to me. --131.181.251.66 09:51, 6 April 2007 (UTC)

[edit] This article misses the point

This article is a collection of half truths and errors, and shows a lack of understanding of the subject matter, and the specific fielded products in this field. Though several sentences are not necessarily wrong, they are not fully correct either. Even a casual perusal of the available literature would do better. For example, http://www.irconnect.com/noc/press/pages/news_releases.html?d=14930, where a discussion about the completion of the initial DIRCM Program is discussed, and then http://www.globalsecurity.org/military/library/news/2007/06/mil-070620-northrop-grumman01.htm, where discussions about one of the more recent installation programs is discussed. In between, there are dozens of major published releases that actually describe the system. In fact, just including a link to the public release position (http://www.es.northropgrumman.com/solutions/nemesis/) is a better idea. —Preceding unsigned comment added by Joat23 (talk • contribs) 07:51, 4 April 2008 (UTC)
