Fatigue Technology, Inc.

Fatigue Technology, Inc., a Berkshire Hathaway subsidiary headquartered in Tukwila, Washington, manufactures precision aerospace components and cold expansion technology solutions for military aviation maintenance and repair, operating exclusively as a prime contractor (100% of recent awards) to the Defense Department and allied defense customers with no set-aside designations across its footprint.

Fatigue Technology's capability portfolio centers on specialized aerospace fastening hardware, bushings, sleeves, expansion sleeves, spacers, washers, adapter bushings, panel fastener inserts, aircraft repair kits, and cold working tooling kits for F-16 fighters, MH-60 helicopters, CH-53K King Stallion aircraft, and related military platforms. Recent representative work includes a $2.19 million definitive contract (awarded January 2026) from Air Force Materiel Command for F-16 wing pylon rib bushing repair services at a South Korea location; a $1.52 million definitive contract (September 2024) for Korea FTI wing pylon repair; a $201,604 definitive contract (July 2025) from Air Force Materiel Command for onsite repairs on Norway's F-16 Block 15 MLU aircraft; a $196,691.16 purchase order (August 2025) from Ogden Air Logistics Complex for F-16 wing pylon rib repair services at Misawa Air Base; and a $174,526 purchase order (June 2024) from Air Force Materiel Command for F-16 wing tip pylon repair work.

Fatigue Technology's customer concentration is heavily weighted toward Defense Logistics Agency Aviation, which accounts for 1,515 awards and $37.1 million combined potential value—36% of the top-five customers' combined awards and volume-dominated across the recent portfolio. The top five funding agencies by award count (covering 76% of awards) are DLA Aviation ($37.1 million), DLA Troop Support Hardware ($13.3 million), DLA Troop Support Construction and Equipment ($5.4 million), DLA Land and Maritime ($1.6 million), and Coast Guard ($1.9 million). By potential-value ranking, Air Force Materiel Command and its subordinate organizations (Lifecycle Management Center at Hill, Ogden Air Logistics Complex) anchor the largest dollars at $64.7 million and $11.4 million respectively, reflecting the company's specialization in F-16 and related fighter-platform repair work. Fatigue Technology also holds a single-award Indefinite Delivery Contract with DLA Land and Maritime (established August 2024, $250,000 ceiling) for retainer, nut, and bolt components supporting aviation maintenance across the Defense Department, Department of Homeland Security, NASA, and the Armed Forces.

Activity has grown substantially from 70 awards in 2022 to 162 in 2024, with 105 awards through 2025 and 14 awards recorded in the first quarter of 2026. Sixteen awards carrying combined potential value of $3 million reach completion within the next twenty-four months, representing a modest recompete exposure relative to the total portfolio. The company's top-five parent vehicles by task-order volume and value include Indefinite Delivery Contracts SPM5AY10D0102 (176 task orders, $2.6 million), FA823209D0001 (96 task orders, $9.2 million), and SPE4A616D5855 (54 task orders, $4.4 million).

Fatigue Technology's subcontract footprint is minimal—20 named sub-awards represent less than one percent of total recent activity. Named prime contractors receiving Fatigue Technology as a subcontractor include Lockheed Martin Corporation (main rotor head organic repair capability, Precision Strike Missile FORCETEC rivetless nut work), Sikorsky Aircraft Corporation (Black Hawk production contract valve assembly conversion, Combat Rescue Helicopter spindle components), and Bell Textron Inc. (Future Vertical Lift FLRAA bushing work). The company describes itself as a Berkshire Hathaway subsidiary specializing in cold expansion technology and precision aerospace components, with over 200 purchase orders and definitive contracts across federal agencies since SAM registration in December 2001.

Fatigue Technology's product portfolio concentrates on the lower end of the supply chain: the top NAICS categories are Bolt, Nut, Screw, Rivet, and Washer Manufacturing (746 awards), Other Aircraft Parts and Auxiliary Equipment Manufacturing (608 awards), and Hardware Manufacturing (477 awards). The top PSC categories mirror this focus—Bushings, Rings, Shims, and Spacers (781 awards), Bearings, Plain, Unmounted (608 awards), and Nuts and Washers (426 awards). Fatigue Technology operates as a child of Precision Castparts Corp., a for-profit manufacturer and federal contract prime awardee headquartered in Lake Oswego, Oregon, though the parent relationship does not materially alter the subsidiary's independent contracting posture or capability framing.
