M&B Assembly Corp

M&B Assembly Corp, a Hispanic American-owned, self-certified small disadvantaged business (SDB) manufacturer based in Gardena, California, operates as a prime contractor delivering precision aerospace component manufacturing—primarily aircraft structural parts, assemblies, and machined components—to the Defense Logistics Agency (DLA) for military aircraft fleet sustainment and modernization. The company is also self-certified as a HUBZone joint venture and competes across both set-aside and full-and-open categories, with set-asides (Total Small Business) recurring across roughly 15–20% of recent prime awards.

M&B Assembly Corp's customer footprint is concentrated almost entirely within Defense Logistics Agency divisions. DLA Aviation accounts for 590 of 626 prime awards ($7.5 million combined potential value, 96% of the portfolio); DLA Land and Maritime holds 22 awards ($222 thousand); and DLA Troop Support Hardware accounts for 14 awards ($71 thousand). Concentration is extreme—the vendor has served only three customer agencies in recent years, all within DLA. Both the award-count and dollar rankings align tightly, indicating that DLA Aviation is both the volume driver and the financial anchor.

The capability portfolio is concrete and narrow: the vendor manufactures aircraft structural components including window panels, door assemblies, fairings, skins, ribs, stiffeners, frames, leading edges, access covers, panels, brackets, fittings, specialized assemblies, and precision-machined aerospace parts. Representative work includes a $545 thousand compensator assembly for aircraft (July 2025, DLA Aviation, firm fixed-price); a $504 thousand radome procurement (August 2025, DLA Aviation); a $185.5 thousand leading edge aircraft component order (October 2024, Total Small Business set-aside); and a $167 thousand structural panel award (June 2025, DLA Aviation, firm fixed-price). The bulk of awards are purchase orders under $100 thousand; the company also executes government first-article-test contracts, trailing-edge strips, and control surface components. NAICS concentration is extreme: 525 of 626 awards fall under Other Aircraft Parts and Auxiliary Equipment Manufacturing (336413); PSC concentration is similarly tight, with Airframe Structural Components (474 awards) dominating the portfolio.

M&B Assembly Corp holds seat on multiple DLA Indefinite Delivery Contracts (IDCs). The top IDC by dollar value is SPE4A719D5588 with 2 task orders carrying $77 thousand combined potential value; three other IDCs appear with single task orders each. These vehicles are single-award, DLA Aviation-issued IDCs with ceilings up to $249,999.99 each, reflecting the vendor's small-scale, specialized role in the DLA's supply chain. The vendor does not sit on government-wide vehicles (GWACs, Alliant, OASIS+) or multi-award schedules; it competes and performs work exclusively through DLA direct awards and IDCs.

Activity has accelerated sharply: the vendor recorded 24 awards in 2022, 15 in 2023, 85 in 2024, and 99 in 2025—a four-fold increase over three years. Most recent award was April 15, 2026 (aircraft window panels, $46.6 thousand, DLA Aviation, Total Small Business set-aside). Recompete exposure is material: 76 awards carrying $3.3 million in combined potential value reach ultimate completion within the next twenty-four months, representing 43% of the active dollar base and signaling substantial recompete activity in the near term, primarily in structural components and assemblies currently held against DLA Aviation IDCs.

The subcontract footprint is minimal: M&B Assembly Corp subcontracts as a sub-tier to S & K Logistics Services LLC on a single balance weight elevation component award (December 2024), with no other recorded sub-awards. The vendor operates predominantly as a prime contractor and has not been documented as a significant subcontractor within the search period. All manufacturing is performed at the vendor's facility in Gardena, California; all funding flows through DLA Aviation or other DLA divisions; and all work is conducted on firm fixed-price purchase order terms with delivery to DLA Distribution facilities. The company carries no disclosed teaming arrangements or strategic partnerships with other primes or integrators.
