ROTHENBUHLER ENGINEERING CO.

Rotenbuhler Engineering Co. specializes in the maintenance, evaluation, and support of military-grade explosive ordnance systems and specialized firing devices, with deep technical expertise in the lifecycle management of MK 186 MOD 2 and MK 67 MOD 0 munitions kits. The company provides Level 1 and Level 2 maintenance services, including system diagnostics, component replacement, and performance validation for defense-critical detonation systems. Their work for the Department of Justice involves the servicing and supply of proprietary firing remotes and associated hardware, demonstrating proficiency in secure, field-deployable explosive initiation systems. Technical capabilities include precision assembly, government-furnished property management, and system-level evaluation of ordnance components under strict military specifications. The contractor maintains a strong, sustained relationship with the Department of Defense, delivering mission-critical ordnance sustainment services for explosive devices used in tactical and demolition operations. For the Department of Justice, they provide specialized support for law enforcement detonation equipment, indicating experience in dual-use defense and public safety applications. Their contract history reveals consistent engagement with agencies requiring high-reliability, regulated explosive systems, suggesting a trusted position in niche national security supply chains. Rotenbuhler Engineering’s primary industry focus is explosives manufacturing (NAICS 325920), where they engineer and maintain classified detonation systems, complemented by limited work in radio and wireless communications equipment manufacturing (NAICS 334220) for firing remote hardware. This positions them as a specialized provider in defense ordnance sustainment rather than broad-scale electronics manufacturing, serving a highly regulated, low-volume, high-integrity market segment. As a small business structured as a 2L entity based in Sedro Woolley, Washington, Rotenbuhler Engineering operates without federal certifications but maintains a focused presence in the defense and law enforcement procurement markets. Their geographic location supports regional defense logistics networks, and their technical niche ensures relevance in specialized government supply chains requiring precise, compliant ordnance handling and maintenance.
