Hopkins Frank C. Methodology for acceptance criteria for target dispersion characteristics of the armor piercing discarding sabot (APDS) rounds

(Хопкинс Фрэнк С. Методология определения критериев приемлемости для характеристик дисперсии при попадании в цель оперённого бронебойного подкалиберного снаряда). Aberdeen Proving Ground, MD: US Army Materiel Development & Readiness Command. This report develops methodology for acceptance criteria for target dispersion characteristics of Armor Piercing Discarding Sabot (APDS) rounds. The distribution of observed circular probable errors of the reference lot of Cartridge, 105-mm: APDS-T M392 is obtained and is used to derive the operating characteristics (ОС) curves of several acceptance plans. Procedures for developing acceptance plans and their associated 0-C curves are given, and several plans are presented.
