[NOTBUG] MK-20's Don't hit target

[Blinky.ben]

I can’t get the MK20’s to drop all the munitions onto the target area with CCRP/Auto. Don’t know what I’m doing wrong. 
 

I have tried with setting the SPI with the TGP or HUD but the submunitions always fall short for me. I am at 2000ft fly straight and level, I get all the release cues but they just always fall well short of the target as in none of them hit a single vehicle. It’s almost like it’s programmed so the submunitions don’t got past the SPI. I can get them to work with CCIP no problem

 

not home to post a TRK so will do later

 

EDIT: I accidently posted this in the wrong area. I have made a new post please delete this one.

 

Thank you

I can't get the MK-20's to hit the target while in Auto/CCRP. I can dive and get the submunitions on target with CCIP but while in Auto they always fall short. Even if I drop 4x MK-20's with a interval of 200 or more they will always fall short. it's as if they are programmed so the last submunitions hits the SPI and not the First submunitions hitting the SPI then past it.

 

I have attached a TRK showing all bomblets falling a very long distance short of the targets.

I used a waypoint as my SPI for this example but it also happens no matter what I use to mark the SPI

could you try hornet with mk-20?

i checked mk-20 param, the default open height is 457, not quite sure the meaning of other params

[Blinky.ben]

Yeah sure. Can't check today but I will have a go at it tomorrow. Unless someone else can do it before I can

 

thanks

As a guess I wouldn’t think so due to the fact the submunitions are falling very short but they are being dispensed in a way that I would expect with a good spread on the ground. I think this is more that the bombs are being released too early but that’s just me having a guess to be the issue.

try to release mk20 over 1000m agl

I tested the MK-20's with the F-18 and they drop on target as planned. It's almost like the JF-17 is dropping the bombs too early so the submunitions stop before the SPI point. just a theory tho

tried jf17 using same miz

no problem

So it must be related to height.

 

I did some playing around with it and it seems I wasn't allowing much time between dropping them and the point they open.

I've got them working now

 

thanks for your help.

Interestingly, the Raz bam Harrier has a very similar issue with Mk20s.

I have found the clusters discharge at the SPI when used in CCRP.  It is best to set it a little further than where you expect.  Like if you are wanting to hit a line of 5 vehicles.  Set the SPI near the front, I like the second or third vehicle.  Make sure you are going between 450-600kts.  I prefer 500+/- 20kts.  From about 5-10kft agl.  

 

But honestly it is far more accurate to just use CCIP for mk20s.
