Calculating CBU footprint vs Burst Altitude
-
I’ve checked the manuals and I’ve searched the forums, can’t find anything. Is there a chart somewhere?
I can measure the distance of a convoy using the TGP, but I need to figure out the kill zone radius so I can evenly divide the number of CBUs I’m carrying to evenly cover the entire convoy for maximum potential. -
Do you have an Android? Theres a calculator app for that. But the equation is in the realism patch 5 manual, i do t think it was included in 4.33 but if you have an old 4.32 install somewhere itl be in there.

The old Realism Patch 5 Manual on page 86 has a chart that shows pattern diameter versus altitude but I’m not sure if it is still applies to this version.

I don’t have this document. Can someone post the info?

Bearing in mind the higher the burst, the greater the diameter of the footprint, this will inevitably lead to a greater dispersion of the individual bomblets. What would you guys consider the optimum burst altitude versus spacing. Typically, I use a BA of 2200 feet with a 500 foot spacing in a 15 degree dive at 400kts. This gives me a pretty good result against a column. As the dispersal diameter of CBU-87 (my cluster munition of choice) is 1700 feet, could I afford to increase the spacing to say 850 feet for a longer trail without loosing effectiveness?

Hope it helps someone.
Cheers!

Thanks everyone.

I could be wrong but I don’t think its modeled in BMS or it was broken.
In our AF days we regularly changed our BA settings for different targets but in the transition to BMS it didn’t seem to matter much.

It depends on a lot of things. I don’t like to use typical Burst Altitudes and ripples, I want the mathematically right stuff.

Are you sure? In 4.32 I did notice it mattered, if I dispersed them too much for a group of 3 heavy armor tanks in a tank-wedge(tank formation??) they wouldn’t blow. With the bomb explosion diameter set to the diameter of the tank formation with plus maybe a little error for inaccuracy due to delivery, they blew every time. But I haven’t done any of that since 4.33 somehow. Maybe I’ll try again later. I thought in 4.33 you had the explosion diameter cue show up on the TGP for your burst altitude.

Thanks for this - I’ve always just ballparked my BA / spacing, but that table is exactly what I want!
