Why can't I destroy tanks with CBU-97

As the topic sais: I struggle with the CBU-97 (and other CBU variants) against armored targets.

Normally I would use GBU or Mavericks against tanks when selecting weapons myself, however I see that JTACs tends to request CBUs if I carry them.

1 - I've entered the wind informed to me by the JTAC, however I still seem to miss when bombing in CCRP mode. I do not change any other settings except changing from CCIP to CCRP.

2 - Is it possible to take out several targets with one bomb? Is this why JTAC seem to request them?

Thanks for helping.

What is your HOF setting on your CBU's I normally keep mine at 500 and I usually only drop them (97's) in CCIP. Also in my exp I have found that at least on T-80's it takes 2 CBU's to kill it. or 1 CBU and a gun run. T-72's and below can be killed by 1 CBU. and if you line your ingress up right along with wind dir you can kill at least 2. Of course all this is with a HOF of 500. I cannot say about HOF greater then that, only that I had a hard time hitting anything due to Bomblet drift with anything higher HOF then that. Others will chime in shortly.

The problem is with the wind. The container's fall until release of the "skeet-tubes" (don't know the correct term) is corrected by the IFFCC. When the parachutes open they glide and wind has stronger effect, which is not accounted for by the IFFCC (the wind correction is still not modeled AFAIK), so you need to correct manually.

Either put the SPI at a corrected point "beside" the target, or better align against the wind direction, especially if the target is moving.

Try to change the HoF, basically experiment with different settings to get a feel for the spread.

To my experience the skeets are quite effective when searching for targets and when you get them at least close to the vehicles, they hit quite well.

My experience with CBU-97 is that, if they hit a T-72, T-55, BMPs or BTRs they are done. :D I'm not sure about T-80 / T-90, though, need to check that...

I prefer CCIP delivery for dumb bombs (3/9 selected), and after entering wind info into LASTE my CBU-97's make a nice smoking mess out of the T-55 in Shooting Gallery single mission

great idea

can you provide any info how can i make this procedures

a little tutorial

I have no problem using ccrp with the 97. Just set the HOF to 900 or 1200.

The default of 1800 is a bit too high.

setting HOF of 2200 or even 3000 the target will be hit

the problem with the '97 begins when a strong wind exists so you have to decrease your HOF to a value of 500 or 900

now i have to test this with LASTE wind delivery option on the CDU and report back

The wind correction cannot work for a simple reason, the bomblets released by the CBU do not have any wind correction kits. So, as soon as they are released, they drift according to the wind and nothing can be done about it. That's why decreasing the HOG altitude will help, since the skeets cannot drift too far away.

I wonder why the cannister guidance is not wind corrected to account for skeet drift. Seems like that should be easily doable, and tho not perfect, would improve bomblets on target.

Because when employed correctly there is no time for the BLU-108s to "drift".

What is the proper procedure for employing them?

Before considering that, everybody is advised to read the last page of the thread of all threads about LASTE wind correction:

In fact I did fall for the placebo effect, either. :D ...and after testing again and again, with and without corrections, it is no difference. What I found matters is: wings level, upwind /downwind vs. crosswind and of course, stable dive angle... :thumbup:

whats weird is when i use CBU-97, the bomblets land no where near the targets but the targets still explode.

Hmm, go to youtube and enter "Textron CBU-97" and have a look? :music_whistling:

Stupid question.. is there a gauge or symbol in the A10 that tells you where the wind direction is coming from?

Nope. but you can look at smokestacks.

Listen to the ATC when you ask for engine startup, he gives you direction and wind speed. At least "near the airfield".

Actually there is also a wind "gauge".

The LASTE system has a wind indicator: On the UFC press FUNC - SYS(1) then on the CDU Page (Right MFCD), select LASTE (OSB 7), then WIND (OSB 10).

Now in the upper right corner there is a line that looks like: 239/008 -4

239 = wind direction

008 = speed in m/s

-4 = temperature in °C

EDIT: I forgot - the indication is valid for the current height you're flying at. If the wind is much stronger at the ground or vice versa it just gives an indication... you can still go down to 2000 ft and check, though.

...and no: the windedit / layer correction feature is not implemented, AFAIK, but I trust Eddie and BlueRidge know what they are doing. :D

Have you tried dropping two CBU-97s in ripple single? The overlap near the center of the drop line should provide better coverage for the core of the target area.

As mentioned before, I also use low altitude HOF values when dropping in windy conditions.

Here's a great video I used to get comfortable with the CBUs.

Don't trouble yourself, this is NOT functional in the sim! Read Shagrat's post again:

I had the same problems with the CBU's than I read the post about changing the oepning altitude of the CBU's and they've been working a charm.

I have them open at 700ft and drop them in CCRP (I'm no CCIP fan) and I've managed to kill 3 T-72s with 1 GBU-97 on several occasions (they need to be close enough together, of course).

As the topic sais: I struggle with the CBU-97 (and other CBU variants) against armored targets.

Normally I would use GBU or Mavericks against tanks when selecting weapons myself, however I see that JTACs tends to request CBUs if I carry them.

1 - I've entered the wind informed to me by the JTAC, however I still seem to miss when bombing in CCRP mode. I do not change any other settings except changing from CCIP to CCRP.

2 - Is it possible to take out several targets with one bomb? Is this why JTAC seem to request them?

Thanks for helping.

Post a track please

AGREED.
