Jones Engineering & Manufacturing, Inc.

Jones Engineering & Manufacturing, Inc., a small for-profit manufacturer based in Rose Hill, Kansas, supplies precision-engineered mechanical components to the Department of Defense as a prime contractor on firm fixed-price purchase orders and delivery orders, competing under full-and-open procurement across multiple Defense Logistics Agency sub-agencies with occasional small business set-aside awards.

The company manufactures and delivers specialized mechanical parts and assemblies for defense logistics and equipment maintenance across military vehicles, aircraft, and weapons systems. Representative work includes a $338,259 total small business set-aside purchase order from DLA Land and Maritime (October 2024) for 140 cylinder assemblies; a $166,960 small business set-aside award from the Oklahoma City Air Logistics Complex (April 2025) for B-52 engine trailer adapters; and a $129,056 firm fixed-price order from DLA Land and Maritime (September 2023) for 53 cylinder assemblies. The company also holds a single-award Indefinite Delivery Contract (SPE7L324D61ZY) with DLA Land and Maritime, valued at $250,000 with an award date of April 24, 2024, for recurring procurement of cylinder assemblies at an estimated six orders per year. Cylinder assemblies represent Jones Engineering's flagship product, appearing across scores of individual purchase orders and delivery orders spanning the past decade.

Customer concentration is acute and agency-specific. The top five customers by award count account for 96 percent of recent awards, dominated by DLA sub-agencies. DLA Land and Maritime leads with 234 awards totaling $3.9 million in combined potential value, followed by DLA Troop Support Construction and Equipment with 144 awards valued at $736 thousand. DLA Aviation rounds out the top tier with 80 awards worth $215 thousand. Department of the Navy Naval Supply Systems Command (14 awards, $82 thousand) and Naval Air Warfare Center (7 awards, $276 thousand) represent secondary customer streams. Notably, Naval Air Warfare Center ranks third by dollar value despite eighth-place ranking by award count, reflecting higher average contract values on Navy aeronautics work.

Activity has declined year over year from 65 awards in 2022 to 14 awards in the first half of 2026, signaling either market contraction or a shift away from small-dollar spot buys. Combined potential value across all awards stands at $5.4 million, with $5.5 million obligated — indicating the vendor has delivered against most contracted work. Over the next twenty-four months, only two awards totaling $13 thousand face completion and recompete exposure, suggesting limited near-term pipeline vulnerability.

Jones Engineering competes predominantly under full-and-open procurement (nearly all recent awards carry no set-aside designation) but qualifies as a small business and wins occasional total small business set-asides. The vendor works exclusively as a prime contractor; a single sub-award listed in the portfolio (December 2022, $value not provided, under S & K Federal Services LLC for aircraft parts sourcing) is negligible to the footprint and does not characterize the business model.

Product portfolio concentration reflects the company's position as a specialized mechanical-components supplier. The top NAICS categories are Other Aircraft Parts and Auxiliary Equipment Manufacturing (145 awards), Fluid Power Pump and Motor Manufacturing (56 awards), Hardware Manufacturing (52 awards), and Bolt, Nut, Screw, Rivet, and Washer Manufacturing (46 awards). Top PSCs include Aircraft Ground Servicing Equipment (131 awards), Miscellaneous Power Transmission Equipment (93 awards), and Power and Hand Pumps (70 awards). This category concentration underscores a narrow, highly specialized portfolio: the vendor is a precision machining and assembly house serving defense logistics demand for commodity and semi-custom components, not a diversified service provider.

Major supplier of aircraft ground support and handling equipment, in-house custom welding and sandblasting, design and fabricate prototypes. Expanded into agricultural and commercial markets includes powerlifting trailerse to be used in all areas.
