D & D Machinery & Sales Inc.

D & D Machinery & Sales Inc., a woman-owned small business based in San Antonio, Texas, manufactures and supplies specialized ground support equipment, aircraft components, and industrial machinery to the Department of Defense as a prime contractor (95% of recent awards) and subcontractor, competing predominantly in full-and-open procurements rather than set-aside vehicles.

The vendor's federal footprint centers on aircraft ground support equipment and spare parts for defense logistics operations. Representative prime work includes a $16.6 million delivery order from Air Force Materiel Command's Aeronautical Systems Center (awarded August 2022, set-aside for total small business) for C-17 Globemaster III ground handling engine trailers under an underlying single-award indefinite delivery contract; a $112,191 purchase order from Defense Logistics Agency Troop Support Construction and Equipment (January 2024) for three hoisting units; and a $99,771.63 purchase order from DLA Troop Support Construction and Equipment (March 2025) for three aircraft hoisting units under a total small business set-aside. In its subcontractor role, D & D Machinery supplies aerospace support components to The Boeing Company on C-17 Globemaster III sustainment and F-15 development programs, with recent sub task orders dated through November 2025, and to S & K Aerospace, LLC for munitions conveyor assemblies.

Customer concentration is heavily weighted toward Air Force programs. The Department of the Air Force Materiel Command Aeronautical Systems Center anchors the dollar footprint at $67.7 million combined potential value across seven awards—nearly two-thirds of the entire vendor portfolio—with additional concentration in Air Force Materiel Command's Lifecycle Management Center at Robins Air Force Base ($4.8 million across thirteen awards) and Warner Robins Air Logistics Complex ($3.2 million across two awards). The Defense Logistics Agency's three primary divisions (Land and Maritime, Troop Support Construction and Equipment, and Aviation) account for 149 awards with combined potential value of $3.3 million, driven by high-volume, lower-dollar spot purchases of ground support components. Five customer agencies account for 78 percent of award count.

The vendor holds access to multiple indefinite delivery contracts anchoring its prime work. An indefinite delivery contract with Air Force Materiel Command's Aeronautical Systems Center (ID F0863503D0155) carries 18 task orders valued at $11.9 million combined potential value for C-17 ground support equipment. The vendor also holds two single-award IDIQs with DLA Land and Maritime: one awarded March 16, 2026, with a $350,000 ceiling expiring March 16, 2027, and a second awarded October 10, 2025, with a $250,000 ceiling expiring October 10, 2026, both structured to supply mechanical power transmission components and specialized ground support equipment under total small business or full-and-open designations.

Activity trajectory shows sustained growth in recent years, rising from two awards in 2022 to fifty-five in 2025 and thirty-four year-to-date in 2026. This growth reflects increasing order frequency from DLA's construction, aviation, and land-maritime divisions, with typical order values ranging from under $1,000 to $40,000–$100,000 for larger equipment procurements. The vendor faces limited near-term recompete pressure: sixteen awards (combined potential value $388 thousand) reach ultimate completion within the next twenty-four months, primarily smaller DLA spot purchases rather than large IDIQs or sustainment contracts.

The vendor's portfolio spans aircraft components (hoisting units, pneumatic motors, hydraulic pumps, cable assemblies, brackets, shafts, bushings, lock sets, protective dust caps, filter driers, and cargo tie-down equipment), with primary NAICS concentration in other aircraft parts and auxiliary equipment manufacturing (43 awards), rolling mill and metalworking machinery manufacturing (35 awards), and bolt, nut, screw, and rivet manufacturing (22 awards). The company has been registered in SAM since February 2002 and competes across full-and-open procurements and, where applicable, total small business set-asides. Most recent awards carry no set-aside designation; approximately one-quarter of the portfolio is designated total small business or woman-owned small business set-aside. The vendor does not hold positions on government-wide acquisition contracts or agency-wide BPAs but operates under individual DLA IDIQs and Air Force Materiel Command single-award indefinite delivery contracts, making its competitive access agency-specific and program-specific rather than government-wide.
