Harlow Aerostructures, LLC

Harlow Aerostructures, LLC, an SBA-certified HUBZone small business based in Wichita, Kansas, manufactures structural aircraft components and fasteners for the Defense Department as a prime contractor (86% of recent awards) and as a subcontractor to major aerospace primes. The company is a for-profit limited liability partnership with one named subsidiary, Valley Tool and Manufacturing LLC, and competes predominantly under full-and-open solicitations rather than set-aside vehicles, though approximately 27% of recent prime awards carry Total Small Business or other set-aside designations.

Harlow's federal footprint is heavily concentrated in Defense Logistics Agency Aviation. The top five customer organizations account for 83% of recent awards, with DLA Aviation dominating at 185 awards valued at $6.6 million combined potential value, followed distantly by DLA Land and Maritime (53 awards, $551 thousand), Naval Air Systems Command (28 awards, $2 thousand), DLA Troop Support Hardware (25 awards, $178 thousand), and DLA generic (23 awards, $4 thousand). This concentration reflects Harlow's core capability: supplying repair and sustainment components — aircraft skins, panels, frames, longerons, fairleads, bushings, sleeves, brackets, and fasteners — to support multiple military aircraft platforms through DLA Aviation's logistics supply chain. Representative prime work includes a $165.3 thousand Total Small Business set-aside for structural aircraft panels (December 2023), a $131.4 thousand Total Small Business order for aircraft skin components (February 2025), and a $84.3 thousand Total Small Business panel delivery (June 2024), all to DLA Aviation. A single-award indefinite delivery contract with DLA Aviation awarded in September 2021 carries a $2.0 million ceiling and remains valid through September 2026, serving as the parent vehicle for recurring small-dollar purchase orders.

Harlow's prime award portfolio centers on purchase orders and delivery orders under that DLA Aviation IDC and a handful of other smaller DLA vehicles (SPM40605D2035, FA862819D1000, FA863420D2704). Most recent awards cluster in the low-to-mid five-figure range with firm-fixed-price pricing. The category concentration shows the vendor's narrow specialization: Other Aircraft Parts and Auxiliary Equipment Manufacturing (129 awards), Aircraft Manufacturing (49 awards), and Ball and Roller Bearing Manufacturing (33 awards) dominate the NAICS footprint, with Airframe Structural Components (123 awards) and Bearings and fittings topping the PSC ranking.

Activity accelerated from 11 awards in 2022 to 40 in 2025, though only 2 awards appear in 2026 year-to-date. Six awards (combined potential value $243 thousand) reach ultimate completion inside the next twenty-four months, creating modest recompete exposure. Combined potential value across the portfolio sits at $7.6 million, but combined obligated dollars total $11.9 million — 157% of potential value — a signal that many awards have been exercised, extended, or modified above their initial ceiling.

In its subcontractor role, Harlow supplies structural aircraft assemblies and components to The Boeing Company (B-52 commercial engine replacement program rapid prototyping, F-15EX lot advanced procurement, MQ-25 EMD, aileron and panel assemblies), Bell Textron (Future Vertical Lift FLRAA frames, fittings, and assemblies), Bell Boeing Joint Project Office (V-22 nacelle improvements and CMV-22 production frame and rib assemblies), Sikorsky Aircraft (H-60 new hulls and MH-60T components), and Lockheed Martin (aircraft fastener work). These relationships position Harlow as a Tier 2 or Tier 3 supplier embedded in major defense platform production and sustainment pipelines.
