MARINO JOHN J

Marino John J specializes in the design and manufacturing of precision RF and microwave components for defense applications, with a primary focus on fixed attenuators, electronic connectors, and waveguide assemblies. The contractor delivers mission-critical passive components used in radar, communication, and electronic warfare systems, demonstrating deep expertise in RF signal conditioning, impedance matching, and high-frequency signal integrity. Their work includes the production of gaskets and sealing devices that ensure environmental protection in ruggedized military hardware, alongside specialized waveguide covers and connector receptacles engineered for EMI shielding and thermal stability in harsh operational environments. This technical proficiency in RF subsystems and electromechanical enclosures positions them as a niche supplier for demanding DoD systems requiring reliability under extreme conditions. The contractor maintains a consistent and exclusive relationship with the Department of Defense, supplying components used in tactical communication networks, airborne platforms, and ground-based electronic systems. All recent awards stem from DoD procurement channels, indicating a well-established supply chain role supporting defense electronics modernization efforts across multiple branches and program offices. Their industry focus centers on NAICS 334220, reflecting active participation in the manufacturing of radio and wireless communications equipment, with supplementary capabilities in electronic connector manufacturing (334417) and sealing device production (339991). This places them within the defense electronics supply base, serving as a Tier 2 or Tier 3 manufacturer for subsystems integrated into larger military platforms. As a sole proprietorship operating from Olsmar, Florida, Marino John J functions as a small, agile supplier with no formal government certifications. Their business model emphasizes precision manufacturing of specialized components, leveraging localized production to support just-in-time delivery for defense contractors and system integrators requiring qualified, low-volume RF hardware.
