D-J Engineering Inc.

D-J Engineering Inc., a veteran-owned small business aerospace manufacturer headquartered in Augusta, Kansas, produces precision structural components and aircraft parts for legacy and active military platforms as a prime contractor (94% of recent awards) under total small business set-asides and open competition. The company manufactures airframe skins, panels, ribs, spars, longerons, stiffeners, fairings, frames, brackets, doors, and specialized assemblies for the C-135, B-52, B-1B, E-3, and A-10 aircraft, with NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC 15-P (Airframe Structural Components) as its primary classifications.

D-J Engineering dominates the defense aerospace supply chain for legacy military aircraft through extreme customer concentration. The Defense Logistics Agency Aviation accounts for 1,832 awards (89% of the recent count) and $273.5 million in combined potential value (61% of the total), far exceeding secondary customers. The Department of the Navy Naval Air Systems Command (60 awards, $74.1 million) and the Department of the Air Force Ogden Air Logistics Complex (57 awards, $71.7 million) comprise the second and third tiers. The top five funding agencies cover 97% of recent awards by count and 97% of combined potential value, reflecting near-total reliance on DLA Aviation and select Air Force and Navy sustainment commands for recurring purchase orders and indefinite delivery contracts.

The company's activity trajectory shows growth from 128 awards in 2022 to 301 in 2025, with recent deceleration to 55 awards in 2026 year-to-date. Over the next twenty-four months, 142 awards worth $60.6 million in combined potential value reach ultimate completion, creating substantial recompete exposure across the DLA Aviation and Naval Air Systems Command portfolios that anchor D-J Engineering's business.

D-J Engineering holds nine active single-award Indefinite Delivery Contracts with DLA Aviation spanning 2025 through 2030, with individual ceilings ranging from $250,000 to $3,065,000 for aircraft skins, trailing edge components, longerons, structural brackets, and specialty aerospace parts. The $3.065 million C/KC-135 aircraft skin contract (awarded September 2025, through September 2030) represents the largest vehicle. The company also holds three additional IDVs with Naval Air Systems Command and the Air Force Ogden Air Logistics Complex. Task orders against these vehicles constitute the bulk of recent prime activity—54 task orders under one DLA Aviation vehicle alone carried $334,000 in combined potential value, with individual orders ranging from under $5,000 to over $6.9 million for build-to-print manufacturing of machined assets and specialized structural components.

Representative prime work includes a $6.95 million Naval Air Systems Command delivery order (September 2025) for Harpoon launch canisters manufactured to specification drawings; a $1.29 million DLA Aviation definitive contract (September 2025, total small business set-aside) for B-52 airfoil ribs; a $1.9 million Naval Sea Systems Command delivery order (September 2025) for machined assets to build-to-print; a $1.023 million DLA Aviation definitive contract (September 2025) for B-52 airfoil ribs with extended completion to May 2026; and continuous flow of purchase orders and delivery orders from DLA Aviation for aircraft skins, panels, structural supports, and fuselage components with ceiling values from $10,000 to $877,000.

In its subcontractor role—6% of recent awards—D-J Engineering delivers fuselage firewalls, aircraft access covers, and structural aerospace components to Northrop Grumman Systems Corporation on airframe manufacturing and modernization programs; fuselage firewalls and structural assemblies to Northrop Grumman on aircraft sustainment work; aerospace support and upper-stage manufacturing to The Boeing Company on developmental hardware, Ares I upper stages, C-17 sustainment, and presidential aircraft recapitalization; and contractor logistics support engineering and aircraft parts manufacturing to Vertex Aerospace LLC on E-6B follow-on task orders. The source identifies at least a dozen named prime contractors (Northrop Grumman, Boeing, Vertex Aerospace, and others) D-J Engineering partners with for defense aerospace work.

D-J Engineering operates as a parent company with a named subsidiary, DJ Composites Inc., also designated as a veteran-owned small business manufacturer. The source does not specify composite manufacturing scope; the subsidiary is listed without award activity detail in the source data. Federal award activity concentrates on D-J Engineering Inc. as the named awardee.

The company has maintained active federal contracting registration since at least 2002 and competes predominantly under Total Small Business set-asides on DLA Aviation vehicles, with approximately 50–60% of recent awards designated as set-asides and the remainder awarded through open competition. Set-aside posture recurs across the prime footprint—DLA Aviation single-award IDCs are uniformly designated Total Small Business, and the largest definitive contracts (airfoil ribs, structural panels, airfoil assemblies) carry set-aside designations. This set-aside concentration reflects D-J Engineering's veteran-owned small business status and DLA Aviation's strategic use of small business vehicles for sustained legacy aircraft component supply.
