Following on from a thread I started a while ago.....

.....Ive been doing some more experimenting with the AB series bombs. I was trying to find out if it was worth skip bombing them along a convoy. Concluded that it is definately not worth skipping them, and also that its a lot harder than you think to get them to follow a perfectly parrallel course to the convoy.

Nevertheless, I thought Id put one little video of what I did up on these boards, just so I didnt feel the test was a total waste of time.

Employee of the Year! What a run! That's what I'll be doing from now on!

Your right, at low altitude you don't get good dispersion of the bomblets. I think 500+ meters gives more time for the larger AB bombs to fully deploy and thus a better spread. I've been playing around with these bombs offline and trying to work up a good "toss" method. Approaching the target at high speed, steep pull-up, bomb release, then immelman out the opposite direction. My only problem is finding the right distance to begin the pull-up.

Great bomb for the softer (not tanks) ground targets!

Thanks leitmotiv, appreciated.

The reason I tried this is that I wanted to see if the spread of the bomblets could be concentated (by lots of speed and little altitude) in a narrow "coriridoor" alongside a convoy to cause greater damage than a vertical drop (low speed, lots of altitude) from any given altitude.

The problems encountered were :

1) The bomblets are ejected perpendicular to the convoy (kinda obvious when you think about it!) resulting in only one or two vehicles destroyed for every discharge of bomlets. To disperse the bomblets obliquely to the convoy is not possible because :

2) The bombs need to hit tarmac in order to skip/bounce effectively. As soon as they hit grass you get one skip/bounce and then it stops and detonates.

3) In addition to hitting tarmac, the bomb canister needs to miss the vehicles themselves. One hit on a vehicle and the whole canister detonates, regardless of how many bomlets are still contained therein. In the video clip shown here, the bomb on our right (the aircrafts left) completely detonates on the first truck it hits.

4) Having enough speed to ensure adeqaute dispersal along the road is problematic in that the last two bomblet dispersal detonations are inadequately spaced to produce good damage spread. To increase the spread, the aircraft would need to travel above the speed at which the aircraft would begin to suffer structural damage. This is true of the Junkers 87, and 88. In the clip shown here, only three out of a possible five detonations to disperse bomblets are made before the canister loses momentum and sinks into the ground (could also be to the bomb deviating off the tarmac?). This run is shown at quarter speed, and was made at 600km/h. To increase the speed of the aircraft sufficiently to attain suitable dispersal of the last two bomblet loads would exceed the Ju88s Vmax.


@VonKlugermon, this is the graph I produced in my other thread on the AB series bombs. It show efficacy of each combination of AB bomb against altitude of release. It does assume a vertical dive, but I hope it helps.

So, what's the crack with the ABs?

Everytime I tried them I ended up spraying the schoolyard 3 miles away in the next town that was in line with my run. Net result: taking the register didn't take so long.

I believe that I tried approaching at around 300m at high speed (450kmh) then pulling up to about 30 degrees before releasing although I can't recall ever getting a 'rule of thumb' for how far away I should release. A bit like the old 'filthy pullout' contraceptive technique I was taught at Catholic school, I might add - a couple of seconds in either direction and it's curtains.

Maybe I need a LABS system as described here:


The "over-the-shoulder" method looks interesting!

Even though that did not turn out to be the optimum method---that was a remarkably precise, and demolishing, drop. I had no idea the AB cannister could survive a thump on the ground. During my experiments, I never checked the details/effects of a low release. Great work. That convoy took it in the chops! I found myself groaning to imagine the slaughter that would have resulted from such an attack by a Ju 88 tearing up a road, practically in the grass, and hitting a convoy before they could react. Tactically, I think there is a place for such an attack! Brilliant.

@leitmotiv, I believe it has a place too, and that place is all over the spawn area of the red team! http://forums.ubi.com/images/smilies/winky.gif

@VonKlugermon. thats an interesting technique that Ive not sen before. Thanks for sharing. I can understand its relevance with regards to conventional weapons and not being detected, but nuclear weapons at such a low alt?<div class="ev_tpc_signature">

Its a lot better when used down a runway. As its all paved, the bomb skips properly. Its also much easier to landthe bombs on than a narrow road.

In this example, it takes out eight B-17s. This was just a quick thing I set up, and its not a fully populated airfield. Plenty of bomblets hit the parking area and taxiways.

Does the bomb timer in the setup window determine how long it takes before the AB releases the bomblets?

If so, that's where I have been going wrong.

10-26-2006, 04:12 AM
The bomb delay setting changes the time from the release to the first discharge of bomblets.

Though when I set the delay to 9 seconds, the actual delay is more like 5 seconds.<div class="ev_tpc_signature">

That's really intersting to see. Those are devastating attacks, I would love to see someone pull the second one off on-line. Thanks for submitting this stuff, Hanglands.<div class="ev_tpc_signature">

I just watched the 8th AF nightmare---packed heavy bomber airfield, AB bounding along airstrip like a cannon ball at Waterloo, heavies getting distributed like toy models, add secondary explosions from full fuel tanks/bomb bays, and you have Bomber Apocalypse. If the Luftwaffe had resorted to this kind of raiding, every fighter in the UK would have been occupied defending bomber bases instead of escorting bombers. Would have had the effect of shooting down 500 fighters!

I do use them online with some success against lined up targets. Mostly the FW with the AB500 bomb. Treetop level attack, slight pull up and release. Needs either perfect timing or a looong column of targets.

Skip bombing the AB1000 also works quite well on water, it's just the targets don't really care a lot about fragments.
