About this file
This is an engineering drawing for a shaped charge demonstration assembly, specifically a 15-pound M2A4 loading charge, produced by US Army Picatinny Arsenal in Dover, New Jersey. The drawing documents Part No. 8861565, which is a complete assembly composed of eight sub-components including a closing cap assembly, cone assembly, pad, wood spacer, booster, sleeve stand-off, cone container, and reinforcing ring. The assembly is designed using third-angle projection in accordance with ASME Y14.5-2009 and ASME Y14.100-2017 standards, with material specifications referenced in MIL-A-2550 and MIL-DTL-2156.
The drawing specifies critical loading and assembly requirements, including a minimum 10-pound charge composition B (Grade A or B) per specification MIL-C-401, with 0.5% calcium silicate per MIL-C-51077 as an alternate specification. Key assembly procedures include pressing in the closing cap assembly with adhesive application per MMM-A-189 specification, gaging the detonator well to specifications of 0.25 inches minimum diameter and 2.86 inches minimum length, and loading at ambient temperatures not lower than 15°C (59°F). The assembly must be marked with item nomenclature, explosive fill, and lot number using yellow ink per specification A-A-208. The drawing was most recently revised on August 26, 2024, and is maintained as a CAD-controlled document with design approval by the US Army Combat Capabilities Development Command Armaments Center.
