reported SD10 bombs do not leave craters or disturbed ground

[xvii-Dietrich]

SD10 bombs do not leave any crater, nor disturb the ground in any way.

 

This is independent of the altitude from which they are dropped. It is independent of whether the fuse is mV or oV (although for this munition type it should always be mV). It is also indepedent as to whether the bombs were dropped from AI or a human player. Craters (or at least some for of disturbed ground) are especially important for this munition type, as it was specifically a disruption munition.

Yes these issues need resolved , hopefully these testing provided by dietrich here will help ed resolve this quickly

[xvii-Dietrich]

Cratering and the effect of the munitions is affecting not just the Anton.

 

This is a serious problem affecting the Dora too. And even the Bf 109

We need craters, this provides ways of disrupting an airfield.

SD 10 A - Was a German made fragmentation bomb

 

Why do you think that a relatively small high-explosive fragmentation bomb with 900 grams of explosives should leave craters on the surface?
For the destruction of airfields, special ammunition with a penetrating effect is used.

Well before 2.7 23mm rounds (as well as 30 and 37mm gun rounds) used to leave craters, very small craters, but craters nonetheless.

 

And the 37mm HEI has 127g of propellant, let alone filling. 

 

[xvii-Dietrich]

The basis of the assertion pertains to the SD10A (not SD10C) munition:

•   10kg total weight of munition
•   0.9kg explosive charge
•   86mm munition diameter
•   324mm munition length
•   (fins are extra and are ignored in those dimensions)

This is the equivalent of a heavy mortar shell (examples: M2, M30, GrW 34). There is sufficient documentation of mortar shells of equivalent calibre leaving cratering on non-hardened surfaces and, in some cases, even road surfaces are disrupted. See references below.

 

In the casing of an AB 250, not one, but 17x SD10 sub-munitions are enclosed. There are even more in the AB 500 casing.

 

Disturbance to grass and dirt is therefore expected, and on hard surfaces scorch marks or other indicators of impact.

Thanks for the info!
I think in the field, in the grass, such small craters will not be noticeable. On a dirt road, yes, something will be visible. But from a tactical point of view, all this does not make much sense, since it does not interfere with the vehicles to go, and the planes to take off.
