About this file
This is an engineering drawing specification for a Charge, Demolition, Shaped 40LB, M3A1 (Part No. 8858390) prepared by the U.S. Army Combat Capabilities Development Command Armaments Center at Picatinny Arsenal, Dover, New Jersey. The drawing was generated from a solid model and is CAD-maintained, with the current design activity cage code 19203. The document consists of two sheets detailing mechanical specifications, assembly requirements, and component specifications for this demolition charge.
The charge assembly comprises four main components: a metal parts assembly (Part No. 8858382), a pad (Part No. 8858391), a wood spacer (Part No. 8858392), and a booster (Part No. 8858393). The assembly must be loaded with Charge Composition B, Grade A or B, weighing 30.5±1.5 pounds per MIL-C-401 specifications, with a mandatory 0.5% calcium silicate additive per MIL-C-51077. Key manufacturing requirements include applying adhesive to the detonator well closing cap using a non-spray application method, verifying thread dimensions with a minimum 0.28-inch diameter gage, and marking the assembly with nomenclature, explosive fill, and lot number using yellow stencil ink per specification A-A-208. Applicable standards include ASME Y14.5-2009, MIL-A-2550, and MIL-DTL-46594. The drawing carries a "Distribution Statement A: Approved for Public Release" marking, indicating unlimited distribution authorization.
