These are detailed engineering design drawings for a MIC (Microphone) Support Assembly created by the Naval Surface Warfare Center Corona. The drawings provide comprehensive technical specifications for a custom-designed support system consisting of multiple aluminum components: an external tube assembly, internal tube, base assembly, base socket, base plate, and base gussets. The design uses 6061 aluminum for most parts, with specific measurements and tolerances outlined across 10 technical sheets. Key components include a square tube structure with precise machining details such as wall thickness, hole placements, radii, and specific manufacturing notes like removing burrs and sharp edges. The assembly appears designed for precise positioning and mounting of a microphone or similar sensor equipment, with modular construction allowing flexible positioning and mounting options.
