About the company
Welch Mechanical Designs, LLC, a small manufacturer headquartered in Aberdeen, Maryland, delivers custom precision optics, aerospace-grade instrument enclosures, and lightweight aircraft-mounted equipment racks to NASA and the Department of the Navy as a prime contractor (93% of recent awards) on firm-fixed-price purchase orders under full-and-open competition.
Welch operates as a sole proprietorship and limited liability company manufacturer of goods with over 20 years of experience in federal aerospace and atmospheric research applications. The company competes on commercial-item and standard purchase-order vehicles without relying on set-aside designations; recent representative work includes a $110 thousand purchase order from NASA's Shared Services Center for engineering support and fabrication of 777 airborne instrument enclosures (MBARS, CoSSIR, and CoSMIR) for NASA's Boeing 777 aircraft, awarded August 24, 2026 with completion by November 11, 2026; a $59.2 thousand NASA Shared Services Center order for instrument interface design and structural analysis of microwave instrument enclosures and bulkhead assemblies, completed April 2026; and a $74.2 thousand order from NASA's Shared Services Center for custom off-axis parabolic mirrors, delivered June 2022.
Customer concentration sits almost entirely with NASA. The top five customer organizations account for 58% of recent award count and 88% of combined potential value, dominated by NASA Goddard Space Flight Center (8 awards, $5.2 million combined potential value) and NASA's Shared Services Center (19 awards, $1 million combined potential value), with NASA Langley Research Center and the Department of the Navy Office of Naval Research contributing smaller volumes. The award portfolio clusters in optical instrument and lens manufacturing (32 awards), research and development in physical and engineering sciences (8 awards), and industrial design services (6 awards), with procurement categories anchored to optical instruments, test equipment, and laboratory supplies. Recent activity runs flat: two awards in 2022, two in 2023, one in 2024, two in 2025, and two in 2026, with only one award (the August 2026 $110 thousand instrument enclosure purchase order) reaching ultimate completion within the next twenty-four months.
In its limited subcontractor footprint (7% of recent awards), Welch delivers equipment racks and cabinet systems to Valkyrie Enterprises LLC for MIT Lincoln Laboratory research and development center work and to Yulista Solutions LLC for aircraft maintenance and support services at NASA's Langley Research Center. Service Contract Inventory reporting shows minimal federal services-contract activity: 0.1 FTEs in each of FY2024 and FY2025 as a named subcontractor on two records, indicating that Welch's federal work is predominantly goods manufacturing and fabrication rather than billable labor services.
