C.f. Roark Welding & Engineering Company, Incorporated

C.f. Roark Welding & Engineering Company, Incorporated is a small business Subchapter S corporation manufacturer of precision-engineered aviation engine components and aircraft hardware, operating as a prime contractor on federal defense contracts with no set-aside designation across its core footprint. Headquartered in Brownsburg, Indiana, C.f. Roark competes predominantly in full-and-open procurements and holds a portfolio of 208 awards totaling $84.8 million in combined potential value, with 98% deriving from prime contracts and the remainder from subcontract work.

C.f. Roark's capability portfolio centers on manufacturing combustion chamber liners, afterburner flameholders, exhaust cones, and related jet engine subassemblies for military aircraft propulsion systems. Representative prime work includes a $7.6 million definitive contract from the Air Force Sustainment Center awarded in March 2024 for production of 196 J85 afterburner flameholders, a $5.5 million firm fixed-price definitive contract also from Air Force Sustainment Center for F-100 combustion chamber liner manufacture (awarded September 2024), and a $745,695 definitive contract from Air Force Materiel Command for F-100 combustion chamber liners (awarded July 2025). C.f. Roark also holds an active single-award indefinite delivery contract with Defense Logistics Agency Aviation, valued at $2.0 million through February 2027, covering production of combustion chamber liners and engineering support services.

Customer concentration is extreme and stable. Defense Logistics Agency Aviation anchors 61 awards representing $65.4 million in combined potential value — approximately 77% of total potential value across the portfolio. The Air Force Sustainment Center and broader Department of the Air Force structure account for most remaining dollars; the top five customer entities collectively account for 80% of awards. The vendor serves nine distinct federal agencies but derives nearly all revenue from defense aviation sustainment and procurement across DLA Aviation and Air Force production accounts.

C.f. Roark places task orders primarily under five agency-held indefinite delivery contracts managed by DLA Aviation and the Air Force. The top parent vehicle, IDC SPE4A717D0159, has generated 12 task orders ($514 thousand combined potential value); four additional IDCs contribute between 5 and 10 task orders each. Activity over the past five years has been uneven — two awards in 2022, two in 2023, six in 2024, three in 2025, and one in 2026 — reflecting lumpy procurement patterns typical of production-order manufacturing. Four awards worth $1.6 million combined reach ultimate completion within the next twenty-four months and thus face recompete pressure in that window.

In its subcontractor role, C.f. Roark delivers welding services, sheet metal fabrication, and aviation engine hardware to Rolls-Royce Corporation (T56 component improvement program subcontract awarded October 2025), Booz Allen Hamilton (electron beam welding and complex sheet metal fabrications subcontract awarded December 2024), General Electric Company (aviation engine hardware subcontracts for engine purchases, awarded August 2024), and Am General LLC (auto parts and JLTV family vehicle components, awarded March 2024). The subcontract footprint represents 2% of total award count and is secondary to C.f. Roark's core identity as a defense prime.

C.f. Roark's award portfolio is heavily concentrated in NAICS 332312 (Aircraft Engine and Engine Parts Manufacturing) — 99 of 208 awards — and PSC code AS (Gas Turbines and Jet Engines, Aircraft, Prime Moving, and Components), which represents 157 awards. The vendor operates exclusively from its Brownsburg, Indiana facility and has maintained federal contracting relationships since at least 1980, demonstrating decades of qualification and performance history with defense aviation customers.
