About Welch Mechanical Designs, LLC
Welch Mechanical Designs, LLC, a sole-proprietorship manufacturer based in Aberdeen, Maryland, designs and manufactures precision optical components, aerospace equipment racks, and mechanical assemblies for NASA and the Department of the Navy as a prime contractor (93% of recent awards), competing in full-and-open procurements with no set-aside designation across most of its footprint. The vendor holds over 20 years of experience in custom precision optics and aerospace hardware, with a primary NAICS profile split between Optical Instrument and Lens Manufacturing (32 awards) and Research and Development in the Physical, Engineering, and Life Sciences (8 awards).
NASA dominates Welch Mechanical Designs' customer base. The top five customer entities account for 57% of awards by count and 88% of combined potential value, with NASA Goddard Space Center leading by dollar magnitude at 8 awards worth $5.2 million combined potential value, followed by NASA Shared Services Center at 18 awards worth $933 thousand. The concentration reflects Welch Mechanical Designs' core mission: the vendor manufactures custom off-axis parabolic mirrors, lightweight aircraft-mountable electronics racks (12U and 18U configurations), equipment shelves, and hermetic bulkhead enclosures for airborne research platforms. Recent representative work includes a $59,226 purchase order from NASA Shared Services Center for instrument interface design and mechanical analysis of microwave antenna interfaces for the Boeing 777 aircraft (awarded February 2026), a $30,000 order for 18U Generation 3 lightweight rack kits (June 2023), and a $74,200 order for custom off-axis parabolic mirrors (April 2022). The vendor also holds NASA parent vehicles including Blanket Purchase Agreement NNG10RA31Z and Indefinite Delivery Contracts NNL06AA14B and 80JSC023DA017, with two and two task orders respectively.
Activity has declined materially. The vendor recorded four awards in 2022, dropping to two awards each in 2025 and 2026 (as of mid-February), with one award in 2024. Combined potential value across 72 total awards spans $7.7 million with $3.5 million obligated (45%). In its subcontractor role, Welch Mechanical Designs supplies equipment racks and cabinets to Valkyrie Enterprises LLC for a Lincoln Laboratory research and development center, and 19-inch data racks to Yulista Solutions LLC for NASA's Boeing 777 support. Service Contract Inventory reports negligible federal services activity, with 0.1 FTEs recorded as a named subcontractor in FY2024 — the vendor's footprint is goods and manufacturing, not labor services above the SCI reporting threshold.
