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, aerospace components, and industrial machinery to the Department of Defense as a prime contractor on 95% of its federal awards and as a subcontractor on aerospace support work under Boeing and S & K Aerospace. The company is a for-profit manufacturer of goods, incorporated as a corporate entity, and competes predominantly in full-and-open procurements, though a meaningful subset of its awards carry total small business or woman-owned small business set-aside designations.

D & D Machinery & Sales Inc.'s federal footprint is anchored by a single large indefinite delivery contract with Air Force Materiel Command's Aeronautical Systems Center for C-17 Globemaster III ground handling engine trailers, valued at $57.081 million, which alone accounts for $67.7 million (66% of the vendor's combined potential value across all awards). Beyond that anchor, the company's portfolio consists almost entirely of smaller purchase orders from the Defense Logistics Agency's multiple divisions — Land and Maritime, Aviation, Troop Support Construction and Equipment — for specialized components including aircraft hoisting units, trolley hoists, pneumatic motors, hydraulic pumps, shouldered shafts, cable assemblies, aircraft lock sets, filter drier components, and protective dust caps. Representative prime awards include a $184,014 purchase order from Air Force Warner Robins Air Logistics Complex for two Boeing C-17 slat pump carts (December 2024), a $186,985 DLA Troop Support award for five aircraft hoisting units (February 2023), and a $112,191 DLA Troop Support award for three aircraft hoisting units (January 2024). All named awards are priced firm fixed price.

Customer concentration is extremely high and aircraft-focused. The Department of the Air Force (broadly defined across multiple commands and logistics centers) accounts for 91 prime awards and dominates the combined potential value through the AFMC Aeronautical Systems Center contract. DLA as a whole accounts for 134 prime awards across its three major divisions (Land and Maritime, Aviation, and Troop Support Construction and Equipment), representing the bulk of the company's transactional volume but individually small dollar values. The top five customer organizations (Air Force Materiel Command Aeronautical Systems Center, AFMC broadly, AFMC Lifecycle Management Center Robins AFB, AFMC Warner Robins Air Logistics Complex, and the Air Force) account for 96% of the combined potential value but only 127 of 296 prime awards, reflecting the long-tail distribution where the single large IDC dominates dollars while hundreds of small DLA POs drive volume.

D & D Machinery & Sales Inc. holds two active single-award indefinite delivery contracts: the $57.081 million Air Force Materiel Command Aeronautical Systems Center contract for C-17 ground handling trailers (with delivery order activity through October 2025), a $350,000 total small business set-aside IDC from DLA Land and Maritime (awarded March 2026, expiring March 2027), and a $250,000 single-award IDC from DLA Land and Maritime for shouldered shafts (awarded October 2025, expiring October 2026). These vehicles anchor the vendor's access to the Defense Logistics Agency's procurement channels; no government-wide acquisition contracts or multiple-award vehicles are listed.

Recent activity shows strong growth — from two awards in 2022 to 55 in 2025 — though 2026 year-to-date counts only 19 awards in the dataset's three-month window. The 2025 spike reflects primarily additional DLA purchase orders for routine ground support components. Looking ahead, only twelve awards face ultimate completion within the next twenty-four months with combined potential value of $415 thousand, suggesting modest recompete exposure. The large C-17 IDC delivery order from August 2022 completes in October 2025, representing the principal recompete risk.

In its subcontractor role, D & D Machinery & Sales Inc. supplies C-17 Globemaster III sustainment and minor development aerospace support, F-15 and KC-46 aircraft programs, and munitions conveyor assemblies to Boeing (fourteen sub awards since June 2024) and S & K Aerospace (three sub awards for munitions conveyor assembly in 2024), performing component manufacturing and supply work on larger Air Force prime contracts.

The vendor's business model centers on the narrow, high-expertise segment of aircraft ground support equipment and associated mechanical components — hoisting units, engine trailers, conveyor systems, pneumatic motors, and fastener-related items. Its awards concentrate in NAICS 333618 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), 333517 (Rolling Mill and Other Metalworking Machinery Manufacturing), and 333921 (Conveyor and Conveying Equipment Manufacturing), with PSC focus on Aircraft Ground Servicing Equipment (113 awards across the footprint). The company has operated continuously as a federal contractor since at least 1989, demonstrating sustained capability in military logistics and aircraft support markets.
