Good guide to effective CBU employment?

[SUBS17]

Here's a wee bit of fun :D

 

Commenced dive from 30 000ft, engaging 12 MBT's. Dropped 4 97's and pulled out of dive at 22 000ft. Spiralled down to 13 000ft and watched the fireworks.

That sounds like a good idea I'll have try that.:thumbup:

Hawgsmoke 2010 CBU-97 setting http://www.hawgsmoke.com/assets/literature/Hawgsmoke%20Mils.pdf

 

CBU-87/89 NOTES:

1. CBU-87 deliveries were computed using the following settings:

• RPM: 2000 (S)

• HOF: 1200 (E)

• Timer: 2.23 (S)

2. CBU-87 ripple single deliveries ensure 60’ minimum overlap and 5-7 bomblets/1000 sq. ft,

which is optimized for soft-skinned vehicle targets. For armored targets, employ in pairs or

ripple pairs to achieve 8-12 bomblets/1000 sq. ft.

3. CBU-87 pattern sizes (Length x Width in feet) (Assumes 4 cans delivered)

• VLD: 428 x 292 (Rip Sgl) 351 x 292 (Rip Prs)

• 10 LAHD: 382 x 309 (Rip Sgl) 313 x 311 (Rip Prs)

• 15 LAHD: 372 x 315 (Rip Sgl) 305 x 317 (Rip Prs)

• 20 LALD: 459 x 269 (Rip Sgl) 333 x 268 (Rip Prs)

• 30 DB: 667 x 222 (Rip Sgl) 385 x 219 (Rip Prs)

• 45 DB: 577 x 173 (Rip Sgl) 321 x 172 (Rip Prs)

• 30 HADB: 669 x 200 (Rip Sgl) 372 x 198 (Rip Prs)

• 45 HADB: 563 x 165 (Rip Sgl) 300 x 164 (Rip Prs)

• MAT: 629 x 183 (Rip Sgl) 346 x 182 (Rip Prs)

• 45 HARB: 461 x 151 (Rip Sgl) 261 x 151 (Rip Prs)

Relates to 87's - nothing to do with 97's in there ;)

Viper, did you have to play around with the settings that you posted with the CBU-97? Do you know any good guidelines for using that weapon?

[Wichid]

I put a quick video guide together for using the new CBU-97 with a HoF of 1800ft in CCIP: Manual release.

Not particularly - just set the HOF to 2200. With CCIP you can pretty much choose and know where you're dropping them insofar as spacing is concerned.

 

With CCRP multiple ordinance release, together with 2200HOF, I personally prefer a release interval of 300ft at 250knots to ensure adequate spacing over target. Works well.

 

Not sure what else I can say re guidelines - if you have a specific scenario in mind, feel free to ask :)

[jazjar]

I thought the proper HOF was 1800?

[ralfidude]

I use HOF 1500 instead of 1800. 1800 seems to drift off like a bitch.

 

I also noticed that let's say you do a run south to north on a scatter of metal. Instead of putting the SPI on the middle of the scatter, you would need to put the SPI a tad bit SOUTH of where you are intending. You will see the CBU then drops the munitions DEAD ON. I suppose it depends on the direction of the wind as well.

 

I played Rookie terrorist with a bunch of friends, and needless to say, it was a MASSACRE with one CBU with that technique just DEMOLISHING like 9 pieces of armor in one run. It made me tear up.

[jazjar]

1500, 1800, 2200, 3000! These are all the numbers I have heard are the most effective to employ the new 97s with. Hmm, guess I will just have to check them out myself to see which one is best.

man... just dived too fast CCIPing a cbu87 and cracked the right wing. bloody hell...

Always deploy speed-brake when in a dive with CCIP. Gives you more time and allows for safe recovery from dive.

But you can console yourself with the fact that "the wing did crack because you were going too fast." Isn't it great!:D

Noooooooo.

 

Just plan your attack properly in the first place if you're carrying out an HADB attack. One of the main advantages of HADB is the high speed (and therefore energy) you have at the point of release. In addition to making you a more difficult target and giving you the energy to climb away from the target and escape any threats, the additional speed at release give your weapons more speed which in turn makes them fly a flatter and more accurate patch to the target.

 

45HADB attack profile from 15000 ripping 2 pairs of CBU-87 at 500ft spacing with a HOF of 1200 and RPM of 2000 is a sure fire method of making just about any hostile formation 'go away'.

 

When carrying out a HADB attack my IAS at the release/pull up point is easily over 400KIAS and normally only 20KIAS below max IAS. Just don't yank the stick back, and pay attention to your MRS and altitude. If the run isn't looking good, abort and try again (from a different direction), rather than trying to make adjustments in the dive.

 

If planned an executed correctly you should be at buster from the start of your attack run all the way until you've pulled out of the dive and extended from the target.

yup my main problem is trimming and over G. apparently in the f-16 there's much less worry about that...

indeed, first 2 times i thought was hit by something!

May not be entirely unrealistic...

 

I witnessed 2 panels come off an A-10 West wing at the YXX airshow this summer. Occurred during hard pull at end of simulated strafe run. Found a vid of this event on utube. I got a couple pics of the ground crew retrieving the panels. Each looked to be about 36" square. Demo flight was called off due to technical difficulties. The Hawg landed safely a while later after being checked out in flight by another aircraft. I don't think many people on the ground realized what had happened. The panels fluttering to the ground were not that obvious with all the pyrotechnics going off.

 

pause it at 23-24 second mark.

 

Also reports of a panel coming off same A-10 West demo aircraft the month prior to this in Olympia Wa at the air show there.

 

The sim may be demonstrating, in a more catastrophic manner, a weakness in the A-10 during high speed, high g dive recovery. At light loads I seem to have more issues with ripping the wings off in this manner.

 

Moral of the story seems to be to use caution with how many G you instantaneously load on the DCS A-10c at high speed during dive recovery.

Another consideration not taken into account here (unless I missed it) is wind. With the new parachute modelling, wind is a huge factor. I've done a few missions with strong winds and had to offset the impact point into wind by a few hundred feet of the target. The parachuting skeets drift over the target before their eventual release.

 

Think there is a way of inputing the wind offset but way easy for me to just look at the smoke on the battlefield or chimney stacks then eyeball. You soon get very proficient!
