You said: "These slow-moving sub-munitions aren't going to have much utility against modern SPAAGs"

To me that implies a belief they aren't a threat to them.


Where do I claim that cluster munitions are not a threat?

squirrelshoes wrote:A C-RAM engagement is targeting a single incoming round


I hope you aren't suggesting that C-RAM engagements don't involve destroying multiple incoming rounds because they do.

As opposed to the much slower ballistic trajectory for cluster munitions?


squirrelshoes wrote:You keep talking about this typical dispensing altitude but as others pointed out it depends on what you're trying to hit. If a particular IADS element is the target it could well be a lower burst just like you saw in the video where there was less than five seconds from from burst until impact. Higher burst has more utility for convoys of vehicles and other dispersed targets.


The median ellipse for a T/FDOA 2-ship receiver configuration against one emitter is 2.5 km^2.
If the target can move during the time-of-the-flight of the munition (for JSOW from typical ranges TOF is *minutes*)
the area you have to cover grows dramatically. This either requires high-altitude dispensing (low-altitude is around 0.4 km^2 area effect) or a large number of weapons.

JSOW will have to deal with the possible interception of the bus and its sub-munitions; both are slow and the latter
are very slow so the number of shots the defense gets against both is high.

AARGM-ER doesn't suffer from this problem and has an active seeker to search out the area of uncertainty.

The average altitude for dispensing is GWI was 3000 feet; I believe I read that in the Gulf War air power survey.
But you could argue that the SCUD hunt (where they went for maximum area coverage) distorts the average.

If you can find median dispensing altitudes that would be helpful; most everything has to be inferred from the patterns
the sub-munitions left on the ground in Iraq, Kosovo, Serbia and Afghanistan.

squirrelshoes wrote:Even if it was 30 seconds how many submunitions do you really believe could be targeted by a gun given time to track, calculate firing solution, physically aim the weapon, and confirm a shoot down before moving on to the next?


The whole point of pattern fire is that relaxes the need to abide by this firing doctrine.

Here’s how a radar-killing missile is getting a whole lot more capable [VIDEO 'missile for F-35 explained']

"Here's how a radar-killing missile is getting a whole lot more capable

Northrop Grumman's Advanced Anti Radiation Guided Missile is in the process of some major upgrades that will see it able to be launched from an F-35."

How do you come up with the number for the median?
