Theory and Practice

I covered the precision of the ML-20S gun-howitzer before, but numbers on a table are not quite as fun to look at as the trials themselves. Here are the results from the same gun mounted in a SU-152.

Left group: firing from 1000 meters
Right group: firing from 500 meters."

  1. Is it good or bad?
    Looks like it did not hit the target.
    Sorry for my bad english

    1. The target is smaller than a human figure, which would be way smaller than any target the SU-152 would be firing at on the battlefield. This test was testing precision (the size of groupings) rather than accuracy (proximity to the aiming point).

    2. Finnish testers note, it has good accuracy. They tested it at 400 m.http://www.jaegerplatoon.net/ASSAULT_GUNS.htm

  2. Right, so, it seems the grouping is quite tight and a sight adjustment would bring the fire onto the target pretty consistently.

  3. For two individual test runs, the dispersion appears to be good but how it relates with larger sample sizes is absolutely unknown- particularely in view of Peter Samsonov´s habit of preselected the most encouraging results...

    1. Wow, you admitted that something Soviet is good, that's amazing progress for you. If you have some evidence to the contrary, I encourage you to post it. Otherwise, please stop whining about how all evidence that disagrees with you is "preselected".

    2. Near as I'm aware contemporary observers pretty universally and consistently gave the Soviet artillery arm and their guns high marks, and German artillerists held them in considerable professional regard. Might be bit of a carryover from the Imperial times when the artillery was AFAIK something of an elite service branch - such institutional ethos tends to carry over regime changes.

      Strongly doubt any cherry-picking would be required.
