Just a question, I was discussing with a friend last weekend:
The HARM, the most numerous western Anti radar missile is based on the Sparrow,
with regards to structure and engine, AFAIK. Of the new Meteorite missile, which
will arm the Typhoon and others, a SEAD version is envisaged.
Would it make sense, or is it possible to use anti radar missiles in an air-to-air role ?
A viable target, for example could be an AEW aircraft, but against fighters, too, I
think, use of such weapons would be reasonable, as if not scoring a direct hit, it
would prevent them from using their radars.
But I've never read of something like that ..... ???
 
Well, there was the Seekbat program, which sought to force MiG-25s to fight with their radar off. Details may be found at http://www.designation-systems.net/dusrm/m-97.html.

I've often suspected that one or more of the Russian ramjet-powered missiles has an anti-radar mission against AWACS aircraft, I know I'd set something up that way. By the same token, the anti-radar version of the Kh-41 "Moskito" appears to be aimed at getting Aegis cruisers and other Aegis-equipped ships out of the way as quickly and permanently as possible.
 
The USSR actually put such a missile into service: the R-27EP. It is less able to engage manouvering targets than the other versions, but could have been useful in some circumstances.

The USA tested a few such missiles - Brazo and Seekbat - but never put them in service.

Home-on-jam (HOJ) mode in modern seekers is a reasonable substitute for a dedicated AARM.
 
To Jemiba:
I think you have made a little mistake. As far as I know, HARM is not based on AIM-7 Sparrow. This AAM missile was the base for the AGM-45 Shrike ARM.
ASALM was proposed as a multi role missile, with AAM, ALCM and anti-AWACS capabilities.
Greetings to all.

AFAIK Harm and Sparrow have nothing to do with each other. Neither do Shrike and Sparrow. Shrike is smaller and HARM is larger.
 
Shrike was based around the AIM-7C airframe.
 
Sorry for that, I would have seen, if I wouldn't have looked into just
one book ,and in this case the wrong one ! I'll do better research next
time :(

SOC's right about Shrike. I'd ASSumed that since it's about two feet shorter than AIM-7 and has different fins and wings that there was no chance. Shrike just looks tiny by comparison. Apparently it is though. :-[

Brazo trials
 
Does home-on-jam count? If it does the list is much larger.

Wasn't it stated that an anti-AWAC modification of the Kh-31 was in development?
 
The AGM-122 Sidearm had an Air to Air mode if I recall correctly.
 

In order for your own aircraft to calculate the position of the enemy's aircraft, etc., it is necessary to receive radio waves from the enemy radar, etc.

Until now, only the antenna on the main wing (photo 1, antenna in the red circle) was used, so only the horizontal direction (2D) could be calculated. Therefore, in the 3D high-precision square search system, by adding an antenna (Photo 1, yellow circle) to the vertical tail in addition to the main wing, it is now possible to calculate not only the horizontal direction but also the vertical direction (3D).

From June to October 2012, ground tests and flight tests were conducted at the Air Self-Defense Force Gifu Base and the surrounding airspace, and performance such as sway detection accuracy and reception sensitivity were confirmed.

※Sangtan ... Receiving radio waves from enemy radar, etc. and calculating the opponent's direction.

FY2007 Policy Evaluation Report (Preliminary Project Evaluation)

Department in charge: Technology Planning Officer, Bureau of Accounting and Equipment

Implementation period: June to August 2007

Project name: Research into high-precision 3D direction finding systems

Policy system: 1-4-(2)-① Research

Business content

A prototype of a high-precision 3D direction-finding system will be built that incorporates a direction-finding receiver that employs a time-difference direction-finding method into the existing ESM, and will be demonstrated in an actual flight environment. The system will be mounted on fighter jets and other aircraft, capable of receiving radio waves emitted by the enemy without being detected and detecting the direction in which the enemy is located with high accuracy.

(Note 1) ESM: Electronic Support Measure. A method or device for receiving and analyzing various radio waves emitted by an enemy to estimate the direction, distance, position, and type of aircraft.

(Note 2) Time-difference direction finding: A method of finding the direction to a target by using the time difference between the arrival of radio waves received by multiple antennas located at different distances. This method has high direction finding accuracy.

Costs: Approximately 1.5 billion yen (FY2008 budget request amount, including future expenses)

Happens all the time, especially on DTIC, which seems to change its indexing scheme every couple of years. You can search for the pdf file name to discover the new URL.
 
Notice that the accession number is just AD plus the file name.
 
Talking about the AIM-9C and AGM-122A does anyone know if there are any publicly available technical papers/reports on either missile on the DTIC database?
