CBU99 not accurate at all

[SUHANG]

I believe this is not the first time someone report this problem. After the update of the fuse, the CBU99 plus the MK20 Cluster bombs, are not accurate under CCIP mode and auto mode. The touching ground point always around the target point of the CCIP cross center, rather than direct hit on the target.

This problem occurs under the VT mode, not the PRI mode.  The PRI mode anyway is a dispense immediate mode, so I guess no one requires it to dispense right over the target. PRI mode shall be used to dispense on a wide area for a very low flight over of the target, pe my understanding. It is used for the light armed vehicle or personnel. But for tanks, we shall use VT mode right? of course the dispense hight or time determines the explosion coverage and the density of the bullets, but the problem not is the whole explosion area is far from the targets. 

The CBU99 can set the dispense hight, while MK20 can only send the seconds after drop for dispense. And actually I don't know what is the difference in the game. Is that suit to certain target or not? when shall I use the bomb which can set the dispense hight and when shall be the second?

By the way the CBUs, like CBU97 and especially CBU105, for A10C and F16 are more accurate and deadly. It can cover a wide area and destroy several tanks at one time. Why the CBU99 in FA18 are so useless. not accurate and can destroy nothing. Just like the Cluster bomb for Su25

The Mk20/CBU99 cluster munitions available on the Hornet have always been absolutely rubbish against proper armour, even if you get them on target. TBH I can't even remember the last time I tried using them because they're so incredibly limited in capability against all but the softest of targets. So in that sense, I wouldn't even bother trying to take a tank out with one as they just don't work. I assume they should work to some degree (i.e. be able to seriously damage/cripple an armoured vehicle even if they might not fully penetrate the hull like the skeet-based ones can) but I suspect the damage modelling in-game just isn't up to the job.

 

As you say, the CBU97/105 cluster weapons available on other platforms are a completely different story and can be incredibly effective.

Would the splash damage script help in this case? I’ve used it though I have not tested it with the CBU but the destruction I’ve seen it create in other munitions is quite widespread if not a little over done.

I think you misunderstand how these fuses work 

-The Mk-339 is a mechanical time clock fuse that functions based on time from release. PRI and OPT are just 2 different timing sets that can be chosen. 
-The FMU-140 is a radar altimeter proximity fuse with a secondary time of function. VT1 is rad alt, VT2 is time function. 

Your problem is not with the accuracy, your problem is with their spread. Which you can change by editing the fuse settings to either burst lower (VT1) or by setting a longer function/release them lower.

Not comaprable weapons in the slightest. The 97 and 105 are sensor fused weapons with heat seeking submunitions, of course they're going to be more effective. The 99 and rockeye are not designed for killing heavy armor.
