Linear Motion LLC

Linear Motion LLC UGM Division, doing business as Thomson Aerospace & Defense, manufactures and remanufactures precision linear motion components—ballscrew assemblies, bearing sleeves, ball bushings, ball nuts, and related hardware—for military aircraft sustainment as a prime contractor (93% of recent awards) across defense agencies, with no SBA set-aside certifications. The company is foreign-owned, for-profit, and based in Saginaw, Michigan, with federal contractor status since 2001.

The vendor's customer base concentrates heavily on two defense logistics organizations. Defense Logistics Agency Aviation accounts for 243 awards worth $39.4 million in combined potential value (57% of the total), while the Department of the Air Force Materiel Command Air Force Sustainment Center represents 53 awards worth $28.1 million (41% of the total). Together, these two customers cover 84% of awards by count and 98% of combined potential value. The remaining 19 customer agencies include Defense Logistics Agency Troop Support Hardware, Naval Supply Systems Command, and miscellaneous Air Force commands, collectively representing under $7 million in potential value.

Recent representative prime work spans ballscrew assembly remanufacture for the B-52 Stratofortress (multiple delivery orders totaling over $1.2 million under Air Force Sustainment Center IDVs), E-3 Sentry flap drive ballscrew assembly remanufacture (delivery orders and IDVs through 2026), and C-130 Hercules component refurbishment and repair work. In 2023, Linear Motion received a $1.28 million definitive contract from Air Force Sustainment Center for B-52 ballscrew assembly manufacture and a companion $821 thousand contract for 98 ballscrew assemblies also supporting B-52 maintenance. Naval Sea Systems Command awarded a $343 thousand purchase order in June 2026 for ball nut assembly parts (on-site delivery to Yokosuka), and Defense Logistics Agency Aviation placed a $526 thousand purchase order in May 2025 for ballscrew assemblies with completion scheduled January 2027. The vendor holds multiple single-award IDVs with DLA Aviation and Air Force Sustainment Center; two named IDVs carry combined ceilings exceeding $3.8 million and run through late 2026.

The top five parent vehicles are single-award IDCs. Indefinite Delivery Contract SPRWA111D0018 anchors 14 task orders worth $8.5 million combined potential value, while IDC SPM40005D9401 carries 26 task orders generating $436 thousand in combined potential value. Three additional IDVs (SP040005D9401, SPM47004D1195, FA811810D0054) collectively account for 25 task orders worth $534 thousand combined potential value. The overwhelming majority of work flows through DLA Aviation and Air Force Sustainment Center delivery orders rather than GSA-managed or multi-agency vehicles.

Activity has moderated in recent years after a 2024 peak. Awards per year declined from 21 in 2024 to 7 in 2025 and 4 in 2026 (first half), though the source captures only four awards since January 2026. Combined potential value across all 423 awards (prime and sub combined) stands at $75.4 million, with $46.9 million obligated (62% realization). Only three awards face ultimate completion within the next twenty-four months, carrying combined potential value of $956 thousand, indicating minimal near-term recompete exposure relative to the vendor's recent contract base.

Linear Motion operates as a subcontractor to three major defense primes. Lockheed Martin Corporation accounts for the majority of sub work, with recent sub awards for bearing and shaft assemblies supporting F-35 production (November 2024, December 2023), M-TADS/PNVS bearing and bushing components (multiple awards in 2024 and 2023), and SNIPER/LANTIRN infrared systems (January and February 2025). General Dynamics Land Systems Inc. placed sub awards for M1A1 Abrams tank upgrade components (SEPV3), with sub awards in February 2026 and September 2024. Huntington Ingalls Inc. ordered ballnut and screw assemblies for CVN 80/81 carrier construction (March 2024). Electric Boat Corporation sub awards focused on submarine components and spare parts management (multiple awards 2022–2023). The sub footprint represents 7% of awards by volume but signals strong integration with prime-contractor supply chains for advanced fighter, armor, and naval platforms.

Linear Motion's work concentrates in two NAICS categories reflecting its manufacturing focus: Other Aircraft Parts and Auxiliary Equipment Manufacturing (192 awards) and Aircraft Engine and Engine Parts Manufacturing (105 awards). Under PSC framing, Miscellaneous Aircraft Accessories and Components (172 awards) and Miscellaneous Engine Accessories, Aircraft (95 awards) dominate, with smaller populations in bearings, bushings, and maintenance/repair/rebuild services. The vendor competes consistently full-and-open; no set-aside activity appears in the award record despite its small-business manufacturer profile. Foreign ownership and the highly specialized, source-controlled nature of its components (ballscrew assemblies for legacy military aircraft platforms) position the vendor as a sole-source or limited-competition supplier within the Department of Defense industrial base.
