CBU-105

[Dragan]

Hello, I have a small problem with the use of cluster bombs, specifically the CBU-105, when I create some of my missions I set a minimum wind, literally a breeze, when I get to the target area I drop the 105 on the targets, from a height between 11/12,000 feet, it happens that they totally fail, sometimes I drop only one, sometimes two, but very often it happens that they don't hit a group of vehicles at all, what's wrong or where am I wrong? However, as for the CBU-97, they are much more deadly, I use them even from 10,500 feet and they usually destroy all targets in one or 2 passes...

I forgot to write that I eject them in CCRP mode.

Without a track file or more detail its hard to say.

Are they missing downwind? The CCRP solution puts the bomb at the desired point of function. Maybe you are aiming them to the wrong spot.  Once the canister functions the sensor fused weapons drifts down under a parachute until the weapon activates when it sees a target. If you are aiming them right above the target the canister might open and then the wind pushes the sub munitions off target. Try aiming up wind maybe?

Yeah that's I agree with what you suggest, or find out the wind in a mission (if possible). I used a CBU-105 I believe and while it impacted, it only hit a few targets, but I'm guessing that was due to spread of the targets rather than any issue with any wind (which I believe there was none).

EDIT: i just came back from a training scenario and it seemed to work fine for me. I mean if there's wind it's not affecting the bomb or munitions significantly.

I didn't pay too much attention to aiming upwind or crosswind, I simply threw them at a group of vehicles that were lined up in a diamond formation, so the group of vehicles wasn't scattered either, I fired them as I wrote and in CCRP mode when I get a countdown of 10 and hold the button, I know that of course, but I was never satisfied with their killing, as is the case with the CBU-97, and I mentioned that, their killing proved to be very deadly, at least for me,compared to 105..

I'll try the -97 sometime, may just be how the system works or a bug or some other reason it's doing that. I think at the altitude I drop it at is reasonable for engagement of multiple vehicles, though they're spread out more than your formation, so that may be a factor too.

I set the wind to 3/6/9/12 m per second ( From the ground to 8000) the average altitude is 11 to 12,000 feet, is this altitude enough for the CBU-105, is there a problem with the wind, I assume it is not because they have wind correction + sensors that indicate it

Well I looked up the definition (Okay it was Wikipedia), but didn't mention any notion of it correcting for wind. I don't know off the top of my head if it does, or it just is messed up by the wind or not.

That shouldn't be the case, as far as I can tell.

It used to be DCS made WCMD activate right over the target, so that the CBU-105's ballutes were getting drifted off target by the surface winds. Which, for a wind corrected munitions dispenser, always seemed a fairly odd thing to do. IIRC several forum users said that's not how the system works in real life and that the IFFCC should account for wind so that the submunitions have the best possible chance of hitting the targets, with the aimpoint being the targets themselves.

I don't recall the exact version, but there was a DCS update that made WCMD do exactly that. I tested that with an aimpoint right over a group of targets with a ridiculous crosswind of something like 50 knots on the surface, and the CBU-105 wreaked havoc on that target group.

If it no longer works like that, it would indicate a change and possibly a bug in DCS.

Without a track, it's hard to tell why OP's CBU-105 missed, though.

[Dragan]

I don't know if the CBU-105 has a problem with DCS, I have a problem with them, compared to the CBU-97 with which I am satisfied. I will test them these days and try to add a save track so we will see, it is very possible that they need ideal conditions, whatever that may be...
