Arkwin Industries, Inc.

Arkwin Industries, Inc., a subsidiary of TransDigm Group Incorporated, manufactures precision hydraulic and mechanical aerospace components for military aircraft systems as a prime contractor (99% of recent awards) competing without set-aside designations on the open market. Based in Bethpage, New York, Arkwin is a for-profit manufacturer of goods operating under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and PSC 16 (Aerospace Craft Components and Accessories), competing full-and-open against all qualified vendors.

Arkwin's customer concentration is heavily concentrated with defense logistics agencies. The top five funding agencies account for 81% of recent awards by count and 84% by potential value, dominated by the Defense Logistics Agency (DLA) Aviation (1,795 awards, $108.5 million combined potential value), DLA Land and Maritime (979 awards, $38.6 million), and the Department of the Navy Naval Supply Systems Command (102 awards, $28.3 million). This concentration reflects Arkwin's primary mission: supplying spare and replacement components for military aircraft maintenance and sustainment. Recent prime work spans purchase orders and definitive contracts across the vendor's core competencies: a $2.223 million DLA Land and Maritime purchase order for 45 linear actuator pistons (September 2025), an $836.7 million definitive contract with Ogden Air Logistics Complex for F-16 cylinder assemblies (September 2025), a $1.86 million Air Force Sustainment Center definitive contract for F-16 speed brake hydraulic cylinders (April 2025), and a $1.263 million Naval Supply Systems Command definitive contract for 78 units of hydraulic valve assemblies (August 2025). Arkwin also holds a $250 thousand single-award Indefinite Delivery Contract with DLA Aviation for actuating cylinder components, with an ultimate completion date of July 30, 2026.

Arkwin's top parent vehicles are Basic Ordering Agreements with the Department of Defense: BOA F3460181G1748 (50 task orders), BOA F0960382G0965 (41 task orders), BOA F0960388G0090 (38 task orders), BOA F0960383G1013 (36 task orders), and Indefinite Delivery Contract SP040003D9429 (33 task orders, $3.5 million combined potential value). These vehicles enable rapid procurement of replacement parts for aircraft maintenance operations.

Activity has fluctuated year to year—120 awards in 2022, 183 in 2023, 211 in 2024, 152 in 2025, and 34 through March 2026. Ninety-seven awards (combined potential value $13.3 million) reach ultimate completion within the next twenty-four months, presenting recompete exposure for the vendor. Combined potential value across all awards totals $230.7 million, though combined dollars obligated (roughly $351.2 million) exceed that figure, indicating that Arkwin's actual invoiced revenue significantly exceeds the published ceiling valuations on many contracts.

In its subcontractor role, Arkwin delivers aerospace components and long-lead items to Sikorsky Aircraft Corporation (CH-53K helicopter long-lead items and servocylinder components), The Boeing Company (CH-47F Chinook helicopter advanced procurement systems and F-15EX advanced procurement), General Electric Company (F110 engine spares and F-15EX propulsion system components), and other major primes. These subcontracts position Arkwin as a critical supplier within the broader military aircraft manufacturing and sustainment supply chain.

Arkwin's capability portfolio centers on precision manufacturing of hydraulic cylinders, actuators, pistons, valves, pump components, seals, springs, and mechanical assemblies—components classified across aircraft hydraulic systems (PSC 1270), aircraft engines (PSC 2910), and miscellaneous aircraft accessories (PSC 1680). The vendor competes predominantly open-market, full-and-open, leveraging technical manufacturing capability and competitive pricing rather than set-aside designations. Its long track record with DLA Aviation and other defense customers reflects established capability in source-controlled drawing compliance, military specification adherence (MIL-STD and ISO standards), and rapid delivery timelines. As a TransDigm subsidiary, Arkwin operates within a large defense contractor family but maintains distinct operational and contracting identities, competing as a prime on its own UEI across DLA and military department platforms.
