These engineering design drawings detail a Mic Support Assembly for the Department of the Navy's Naval Surface Warfare Center at Corona, consisting of multiple precision-machined aluminum components. The assembly includes an external tube (24 inches long, made of 6061 aluminum square tubing with 1/4" wall thickness), an internal tube that slides within the external tube, a base assembly with a base plate, base socket, and base gussets, and various specialized mounting hardware like stainless steel clevis pins and threadlocking inserts. The design follows strict dimensional tolerances (±1° angular, ±0.010" two-place decimal, ±0.005" three-place decimal) and specifies meticulous manufacturing requirements such as removing all burrs and sharp edges, and ensuring components like the internal tube slide freely within the external tube.

The technical drawings are comprehensively documented across 10 sheets, providing detailed specifications for each component, including precise measurements, material specifications (predominantly 6061 aluminum), and assembly instructions. The drawing set is marked "APPROVED FOR PUBLIC RELEASE: DISTRIBUTION IS UNLIMITED" and was created by S. SASSE on 4/16/25, with the drawing number IRSSSMS-01. Each component is carefully designed with specific dimensional and geometric tolerancing per ASME Y14.100-2004 and ASME Y14.5M-1994 standards, indicating a high-precision engineering approach typical of naval and military equipment design.
