Thermo Craft Engineering Corp.

Thermo Craft Engineering Corp., doing business as Thermo-Craft Engineering Corp., is a small business manufacturer based in Lynn, Massachusetts, that supplies precision sheet metal, CNC machining, and fabricated defense components to the Department of Defense and federal supply agencies as a prime contractor (77% of awards) and as a subcontractor on defense programs. The company holds a Total Small Business set-aside designation and competes under small business set-asides on roughly half its prime awards; the balance are full-and-open procurements. Thermo Craft Engineering is a for-profit corporation structured as a manufacturer of goods.

The company's capability portfolio centers on precision-fabricated components for military vehicles, aerospace systems, and defense logistics. Representative prime work includes a $201.7 thousand DLA Land and Maritime purchase order awarded September 2025 for 714 units of straight pi-type pipe adapters (NSN 4730011546426) with completion through November 2026; a $167.3 thousand DLA Aviation purchase order awarded July 2024 for an outrigger assembly with completion through May 2026; and a $57 thousand Naval Air Warfare Center purchase order awarded November 2024 for an antenna assembly, where Thermo Craft was the incumbent supplier. The company also holds two single-award indefinite delivery contracts with DLA Land and Maritime, each valued at $250 thousand, for M1 Tank Racks (awarded January 2024 and July 2024 respectively), which have generated multiple delivery orders for vehicle splash guards and related structural components. Tank sections, fluid manifolds, brackets, ladder assemblies, rail guides, splash guards, and cable assemblies constitute the core product mix across recent awards.

Customer concentration is heavily weighted toward the Defense Logistics Agency. DLA Land and Maritime accounts for 18 awards totaling $820 thousand in combined potential value, and DLA Aviation for 11 awards totaling $375 thousand—together representing 75% of award count. The Naval Air Warfare Center accounts for 12 awards totaling $204 thousand. The top five customer offices represent 75% of awards and span DLA (Land and Maritime, Aviation, and Construction and Equipment), Naval Air Warfare Center, and the Department of the Army Materiel Command. Award values are characteristically small, ranging from under $5 thousand to $201.7 thousand, reflecting Thermo Craft's role as a sub-tier supplier within DLA's spare-parts procurement and small business set-aside strategy.

Thermo Craft places the majority of work as a prime contractor on DLA and Naval Air Warfare Center contracts, with lesser volume under Department of the Army Materiel Command contracts. The company's vehicle footprint is fragmented across multiple single-award and multiple-award indefinite delivery contracts with DLA and Navy customers; the top vehicles by task order count are IDCs with the Naval Air Systems Command (3 task orders) and DLA (multiple contracts with 2–3 task orders each). No government-wide acquisition contract participation is evident in the source.

Recent activity has accelerated. Award count grew from 1 award in 2022 to 16 awards each in 2024 and 2025, with 6 awards recorded through early 2026. However, award values remain modest—combined potential value across all 73 recent awards totals $1.8 million, while combined obligated dollars across all awards reach $4.1 million, indicating that prior-year obligations exceed current potential value on the books. Three awards with combined potential value of $300 thousand face ultimate completion within the next twenty-four months, presenting limited near-term recompete exposure at the prime level.

Thermo Craft subcontracts to Raytheon Company on complex welded assemblies, structural and mechanical items, circuit card test fixtures, and multi-function assemblies for Patriot missile systems, international military sales, and Navy depot operations. Recent sub awards to Raytheon span April 2026 back through October 2024, including work on transformers, MK-99 platforms, and non-recurring demands. The company also holds a sub position with Valkyrie Enterprises for DOD line-funded fabrication services. Subcontract work represents 23% of award count and includes international foreign military sales programs routed through Raytheon.

The company's registered status with SAM dates to December 2001. NAICS concentration reflects the core capability: Machine Shops (11 awards), Textile Product Mills (5 awards), Aeronautical and Nautical System Manufacturing (5 awards), and Plate Work and Miscellaneous Fabricated Metal Manufacturing (8 awards combined). PSC concentration aligns with product delivery—parachute and cargo tie-down equipment (5 awards), commercial hardware (5 awards), engine cooling components (4 awards), storage tanks (4 awards), and millwork (4 awards)—though PSC classification inconsistency across the award base suggests primary categorization as a machine shop and sheet metal fabricator rather than a specialized equipment manufacturer.
