A Review of the V50 Ballistic Limit Requirements of MIL-A-46100
Abstract:
This memorandum report is a by-product of that portion of an ongoing project entitled Improved High Hard Armor Steel MIL-A-46100 which involves the creation of a computerized Armor Steel Database for the storage and analysis of ballistic test data obtained on MIL-A-46100 steel by the U.S. Army Combat Systems Test Activity CSTA. The CSTA-furnished ballistic test results spanned the following three 3 MIL-A-46100 Revisions Revision C, Revision C Amendment 2, and Revision D. As the Armor steel Database was being populated, it was observed that the required ballistic limit velocities the minimum ballistic acceptance requirements associated with each of these specification revisions do vary rather significantly. As a consequence of this observation, a complete review of the various revisions and amendments of MIL-A-46100 was undertaken to insure that the specification-revision-dependent results of the ballistic tests being analyzed are, indeed, accurately interpreted and unambiguously compared. This memorandum report presents the salient aspects of this review wherein the differences between the ballistic test requirements of these recent revisions of MIL-A-46100 are appropriately highlighted and documented in a single reference source.
