SEASTRAND ENGINEERING L.L.C

SEASTRAND ENGINEERING L.L.C. specializes in the design, fabrication, and supply of mission-critical metal components and subsystems for defense and aerospace platforms. Their core capabilities include precision manufacturing of aircraft parts, armored vehicle components, and military-grade electrical brackets and mechanical assemblies, with deep expertise in fabricated metal products, propulsion system interfaces, and ordnance accessories. The contractor delivers highly engineered hardware such as hand brake kits, gun tracks, termination assemblies, and non-rotating eye brackets, indicating advanced proficiency in CNC machining, sheet metal fabrication, and assembly integration for ruggedized military environments. Their technical focus on aerospace, ground vehicle, and ordnance systems reflects a specialization in low-volume, high-reliability production where dimensional accuracy, material integrity, and military specification compliance are paramount. The company maintains a consistent relationship with the Department of Defense, supplying specialized hardware across multiple branches and programs, particularly in ground vehicle modernization, aircraft subsystems, and tactical ordnance support. Their work is characterized by direct, mission-aligned component delivery rather than system-level integration, suggesting a trusted supplier role within the defense industrial base. SEASTRAND ENGINEERING focuses primarily on NAICS 336413 (aircraft parts), 336992 (military armored vehicles), and 336320 (military vehicle electronics), positioning them as a niche manufacturer of precision metal components for defense platforms. Their vertical specialization lies in supporting armored vehicle sustainment, aircraft maintenance, and tactical equipment modernization, serving as a reliable source for replacement and upgrade parts under tight operational timelines. As a small, privately held LLC based in Roberts, Montana, SEASTRAND ENGINEERING operates without federal certifications but maintains a focused, agile footprint in the defense supply chain. Their geographic location supports regional logistics for DoD maintenance depots and field units, enabling responsive delivery of mission-critical hardware without reliance on large-scale manufacturing infrastructure.
