MIL-PRF-46103E

Abstract

This specification covers the performance requirements for lightweight composite armor (see <a>6.1</a>). <br>The composite armor should be classified into these types and classes according to its ballistic protection limit (ballistic resistance): </span><pre> Type I 5.56 mm Class 1 - M855 lead ball with steel tip projectile at muzzle velocity (3100 ft (945 m) per second). Type II 7.62 mm (0.30 caliber) Class 1 - Lead or mild steel core ball projectile at muzzle velocity (2850 ft (869 m) per second). Class 2 - Hard steel core armor piercing (AP) projectile at muzzle velocity (2850 ft (869 m) per second). Class 3 - Heavy density core sabot launched armor piercing (SLAP) projectile at muzzle velocity (4000 ft (1219 m) per second).</pre> <br> <strong>Beneficial comments (recommendations, additions, deletions) and any pertinent data which may be of use in improving this document should be addressed to: Director, U.S. Army Research Laboratory, Weapons and Materials Research Directorate, ATTN: AMSRL-WM-M, APG, MD 21005-5069 by using the Standardization Document Improvement Proposal (DD Form 1426) appearing at the end of this document or-by letter.</strong> <pre> Type III 12.7 mm (0.50 caliber) Class 1A - Mild steel core ball projectile at 1000 meters range (1600 ft (487 m) per second). Class 1B - Mild steel core ball projectile at 500 meters range (2000 ft (610 m) per second). Class 1C - Mild steel core ball projectile at muzzle velocity (2850 ft (869 m) per second). Class 2A - Hard steel core armor piercing (AP) projectile at 1000 meters range (1600 ft (487 m) per second). Class 2B - Hard steel core armor piercing (AP) projectile at 500 meters range (2000 ft (610 m) per second). Class 2C - Hard steel core armor piercing (AP) projectile at muzzle velocity (2850 ft (869 m) per second). Class 3 - Heavy density core sabot launched armor piercing (SLAP) projectile at muzzle velocity (4000 ft (1219 m) per second). Type IV 14.5 mm Class 1 - Hard steel core armor piercing incendiary (API) B32 projectile at muzzle velocity (3250 ft (991 m) per second). Class 2 - Hard steel core armor piercing incendiary (API) BS-41 projectile at muzzle velocity (3250 ft (991 m) per second).</pre> <br> <br><b><u>Intended Use:</u></b> The lightweight composite armor covered by this specification is military unique because it is used in applications such as military personnel body armor, aircraft armor, and applique armor for tactical shelters and light vehicles when resistance to armor piercing projectiles and limited multi-hit capability are required. <br>
