кстати о 829
The screening results for the 120mm M829 APFSDS round fired from one tank
battalion deployed to Southwest Asia from Germany are presented and analyzed
in an effort to explain the deviation from expected accuracy. A background
history of the ammunition prior to the screening is presented as well as a
detailed description of the screening process, measurements of hits on the
screening panels, a statistical analysis of the target impacts, and an exterior
ballistic analysis to determine the loss of muzzle velocity needed to account for
the low hits observed. It was found that a loss of about 170m/s muzzle velocity
was necessary to cause the low hits. A mean point of impact was computed for
the battalion and compared to the Computer Correction Factor for the M829.
During the screening in Saudi Arabia about 20 tanks in the battalion
failed to hit the screening panel. There were 10 other tanks who hit the
screening panel but failed to satisfy the screening criterion [1:A-20]. This was a
drastic change from past gunnery experiences where this battalion had to proof
fire four out of 58 tanks at worst. Now there were 30 out of 58 tanks that failed
to screen. The screening failures were analyzed by the battalion master gunner,
the brigade master gunner, the company commander, the brigade operations
officer, and the battalion commander. Most of the shots were observed to be low.
The mean point of impact of the battalion across the board was likewise
observed to be low.
During the time the
battalion was up-loaded, the ammunition was subjected to the constant rain and
high humidity of the north German weather. To exacerbate this problem, the
environmental cover at the rear of the turret bustle allowed water to leak into
the ammunition compartment.
а ниша сверху(вышибные панели) не герметизирована(в случае применения ЯО или БОВ что они планировали делать то ?) ?

тут вот вроде о живучести ствола при стрельбе М829 в различных условиях, не успел дочитать.
