Mcmellon Bros., Incorporated

Mcmellon Bros., Incorporated, doing business as MC Mellon Brothers Inc., is a woman-owned small business manufacturer of precision fasteners and aircraft components based in Stratford, Connecticut, operating as a prime contractor on Defense Logistics Agency purchase orders and as a subcontractor to Boeing, Sikorsky Aircraft, and Lockheed Martin on military rotorcraft programs. The company manufactures self-locking nuts, plain round nuts, gearbox locknuts, and specialized rotor assemblies for military aviation supply chains, competing predominantly on full-and-open procurements with recurring small-business set-aside awards from DLA Aviation.

Mcmellon Bros. derives its revenue from two distinct channels: direct DLA Aviation purchase orders for standardized fasteners, and subcontracts on prime-led rotorcraft and helicopter production programs. On the DLA side, recent prime awards include a $49.2 thousand total small-business set-aside purchase order for plain round nuts (awarded May 19, 2025, DLA Aviation, with completion in July 2027), a $57.9 thousand total small-business set-aside award for 399 units of plain round nuts (April 21, 2025, completion March 8, 2027), and a $44.8 thousand total small-business set-aside purchase order for gearbox locknuts (April 4, 2025, completion March 25, 2027). Mcmellon Bros. also holds an older $32.9 thousand DLA Aviation contract for gearbox locknuts (October 25, 2021, completion October 18, 2025), which reflects multi-year procurement cycles for parts supplied to DLA Distribution in Corpus Christi, Texas. In its subcontractor footprint, Mcmellon Bros. supplies gearbox assemblies, intermediate gearboxes, rotor hubs, main rotor blades, and control units to Sikorsky Aircraft on CH-53K cargo helicopter full-rate production contracts (June 2026 awards and ongoing long-lead items), provides gearbox and blade assemblies to Lockheed Martin on organic repair and spare-parts contracts (December 2025 and September 2025 awards), and supplies materials and components to Boeing on AH-64E attack helicopter production for foreign military sales to Poland, Egypt, and Kuwait (multiple awards August 2026 and earlier) and on CH-47F Chinook production for Germany (May 21, 2026).

Customer concentration is sharp and unidirectional. DLA Aviation accounts for 82 awards and $2.9 million in combined potential value, representing roughly 27% of total awards and 37% of dollars, with the next-largest customers — Department of the Navy Naval Air Systems Command (45 awards, dollar value not listed in the source), DLA Troop Support Hardware (28 awards, $1.7 million), DLA Troop Support Construction and Equipment (31 awards, $486 thousand), and Department of the Navy Naval Supply Systems Command (27 awards) — accounting for much smaller individual stakes. This portfolio concentration reflects Mcmellon Bros.' origin as a DLA supply-chain vendor and continued reliance on that single agency for baseline revenue, balanced by newer prime-contractor relationships with rotorcraft integrators. Among parent vehicles, a Navy Basic Ordering Agreement (N0038320GX901) anchors 24 task orders, an Army Indefinite Delivery Contract (SPM4A612D0248) carries 13 task orders worth $243 thousand, and an Army IDC (SPRPA120D005U) holds 11 task orders, signaling diversification into Army rotorcraft supply chains downstream from Boeing and Sikorsky.

Activity has accelerated from minimal baseline (1 award in 2022) to 38 awards in 2024, followed by a decline to 28 in 2025 and 17 through August 2026. The source covers 302 total awards across a span dating to 1984, but the surge since 2023 reflects expanded subcontracting relationships with major aerospace primes. Combined potential value across all awards is $7.9 million, but combined dollars obligated is $10.3 million — a signal that the company has invoiced in excess of contract ceilings, typical of firms with recurring small-dollar purchase orders and long-tail performance. Only three awards reach ultimate completion inside the next twenty-four months, carrying combined potential value of $152 thousand, reducing near-term recompete pressure.

Mcmellon Bros.' capability footprint is dominated by fastener manufacturing under NAICS 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing), accounting for 95 of 302 awards, alongside 57 awards in aircraft manufacturing and 49 in other aircraft parts and auxiliary equipment manufacturing. PSC-level coding reflects this: 128 awards carry PSC "Nuts and Washers," 36 carry "Bushings, Rings, Shims, and Spacers," and 31 cover gas turbine and jet engine components. The company's subcontract work with Sikorsky and Boeing extends beyond commodity fasteners into rotor hubs, blade assemblies, gearboxes, and control units, positioning it as a supplier of both standardized and engineered components within the military rotorcraft supply chain. The source notes the company has held a SAM.gov registration since 2001, establishing a multi-decade foundation in defense logistics supply despite the recent acceleration in visible awards.
