CBU-97s falling short

[nuNce]

Hello,

could somebody confirm that either this is the expected behaviour or a bug regarding the CBU-97 employment on the SE?

If I aim at the target CBUs fall short, if I correct and aim ahead of the targets (2nd and 3rd pass especially) they fall on target.

I'm aware that on the release notes it is specified there are problems above 1500ft, but apparently they are also present under that altitude, unless I'm doing something wrong.

 

Thanks.

CBU-97 don't have wind correction like the 105 have so i guess it is that.

Might be the wind. I get pretty good results by dropping a ripple of six with an interval of 400/500….its quite a spectacle to watch.

rather than falling short, my cbu's go to about 100m left of the target despite the aligned auto release

I've had the same problems. It is noted in the changelog known issues about them opening prematurely. I've had good results by setting the fuze to 900 ft and putting in roughly a 12 degree dive right when the release que is at about 8 secs. I haven't tried at a lot of different altitudes yet, but seems to work 8k-10k barometric. Hope this helps.

Having the same issue. No problems with laser-guided weapons.

FWIW, the wind does affect CBU-97's, since the fire control computer only gets it to the point of deploying.  After that, the submunitions are hanging in the wind for an additional 10-15 seconds.  in a 10 knot wind, that's 150-250' of drift.

It’s a known bug. Check the release notes. Simple fix is to aim behind target about 100 feet depending on the BA. The trajectory is currently using a normal dumb bomb which is not correct for a cluster munition that uses parachutes.


This is why the -87s don’t fall short or don’t have a problem, but the -97s do. The trajectory is incorrect or being assigned the same trajectory as an -87.
