Form Fit & Function LLC

Form Fit & Function LLC F3 Division, doing business as F3 Engineering, manufactures precision-engineered mechanical and electrical components, spare parts, and hardware for military platforms as a prime contractor (94% of recent awards) across Defense Logistics Agency, Naval systems, and Army programs. The vendor is a self-certified small disadvantaged business and Hispanic American-owned sole proprietorship based in Spartanburg, South Carolina, competing predominantly in full-and-open (non-set-aside) procurement despite qualifying for small-business set-asides on a subset of awards.

F3 Engineering's customer footprint is heavily weighted toward the Defense Logistics Agency and Naval systems. The top five funding agencies account for 80% of recent awards by count. The Department of the Navy Naval Sea Systems Command anchors the dollar value by far — a single $1 billion blanket purchase agreement (BPA) with Naval Sea Systems Command, effective through April 2026, represents $73.55 billion of the $73.67 billion combined potential value across all awards. That BPA dwarfs all other work; the next-largest customer, Naval Air Systems Command Naval Air Warfare Center, carries only $76.1 million across 92 awards. The Defense Logistics Agency Aviation and Land and Maritime divisions are the second-tier recurring customers by order count, with 113 and 110 awards respectively and combined potential values of $7.1 million and $11.5 million. The Army Materiel Command Aviation and Missile Life Cycle Management Command and Naval Supply Systems Command round out the top five.

F3 Engineering's award category concentration tracks its manufacturing posture. The top NAICS codes are Other Aircraft Parts and Auxiliary Equipment Manufacturing (130 awards), Mechanical Power Transmission Equipment Manufacturing (48 awards), and Machine Shops (29 awards). Procurement Service Codes align: Aircraft Maintenance and Repair Shop Specialized Equipment (72 awards), Miscellaneous Power Transmission Equipment (48 awards), and Aircraft Ground Servicing Equipment (37 awards). Concrete recent work includes a $933 thousand definitive contract with DLA Land and Maritime for groove pulleys (October 2023), a $726 thousand purchase order for groove pulleys under SBIR Phase III (April 2024), a $568 thousand Total Small Business set-aside for groove pulleys (July 2024), a $482 thousand Total Small Business set-aside for nonmetallic hose sets (June 2024), a $2.78 million Total Small Business set-aside for Sheave Assembly Pulley Flat units for Aircraft Launch and Recovery Equipment (May 2025), and a $459 thousand delivery order for UH-60M Black Hawk Helicopter spares from the Army Aviation and Missile Command (September 2022).

Activity has accelerated year over year — 26 awards in 2022 to 53 in 2025, with 13 awards recorded so far in 2026 — but awards-per-year velocity masks the lopsided value concentration in the Naval Sea Systems Command BPA. Twenty awards (combined potential value $4 million) reach ultimate completion inside the next twenty-four months and face recompete. F3 Engineering holds five active Indefinite Delivery Contracts with DLA and Naval systems, including single-award IDCs for connecting links ($350 thousand ceiling), shouldered shafts ($250 thousand), and beam hoisting equipment ($349 thousand). The vendor also holds a single-award Total Small Business IDC with Naval Air Warfare Center for beam hoisting equipment through December 2026.

In its subcontractor role, F3 Engineering supplies aircraft components — blade fold pins, grip assemblies, repair kits, bearing-removal plates, and stabilizer shear pin assemblies — to Bell Textron Inc. and the Bell Boeing Joint Project Office. Across subcontract awards dating from late 2023 through May 2026, Bell Textron is the dominant prime, with at least twenty named sub tasks spanning tools, assemblies, and parts for Bell 429, Bell 505, and Future Vertical Lift platforms. The vendor also subs to Bell Boeing Joint Project Office on aircraft gust lock pins and removal tools.

F3 Engineering's BPA with Naval Sea Systems Command and its multi-division DLA relationship position it as a vertically integrated supplier of mechanical and electrical components into defense maintenance and readiness operations. The vendor competes full-and-open on the bulk of awards but holds a HUBZone-set-aside IDC (expired August 2023) and has been designated Total Small Business set-aside on roughly one-third of DLA purchase orders awarded since 2022. Recent activity shows sustained engagement with DLA across Aviation and Land and Maritime divisions and recurring sub work with Bell platforms; the recompete cliff in the next twenty-four months is moderate in dollar terms.
