About this file
This is an engineering drawing for a Fuze Protection Assembly (FMU-143) for the U.S. Air Force, detailed in a two-page technical document with precise manufacturing specifications. The drawing provides a detailed isometric view and cross-section of a complex mechanical component with specific dimensional tolerances, featuring a 3.25-diameter cylindrical design. Material options include alloy steel (AISI 4340) or stainless steel (17-4PH), with strict heat treatment requirements to achieve specified tensile strength conditions.
Key technical specifications include: permanent marking requirements (18894-X20122219-10 in 0.125-inch characters), surface treatment guidelines, and rigorous workmanship standards mandating parts be free from defects like burrs, cavities, pits, corrosion, and other imperfections. The document is marked with Distribution Statement C, authorizing use by U.S. Government agencies and contractors, with a warning about export control restrictions. The drawing is dated February 1974 and represents a precision-engineered component likely used in military or aerospace applications.
