National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Analysis of the 120mm M829 Screening in Operation Desert Storm.

ADP009089

Publication Date	1993
Personal Author	Dillon, R. E.

Abstract	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.
