Military Naval Power Systems

Marine environments impose corrosive conditions, dynamic loading from wave action, and mechanical shock from weapons fire or underwater explosions. Naval power supplies require conformal coating, robust filtering, and mechanical designs that survive both operational vibration and shock testing. Horizon PSS provides power solutions engineered for continuous operation in high-humidity, high-salinity conditions while maintaining power quality for sensitive electronics including sonar arrays, electronic warfare systems, and command and control networks.

Our naval power systems comply with the following specifications:

• MIL-STD-1399 – Electric power system interface requirements for shipboard equipment
• MIL-DTL-901 – High-impact shock qualification for naval equipment
• MIL-STD-461 – EMI control requirements for shipboard electronics
• MIL-STD-167 – Mechanical vibration standards for shipboard equipment
• NAVMAT P-9492 – Random vibration testing requirements for naval vessels

Horizon PSS maintains the test capabilities and engineering expertise necessary for naval qualification programs. We manage shock and vibration testing coordination, provide audit-ready compliance documentation, and support configuration management throughout vessel construction and service life. Our team understands the unique challenges of submarine power systems, autonomous underwater vehicle integration, and surface ship electronics modernization. From initial RFQ through fleet deployment, we deliver lifecycle-responsible power solutions with transparent NRE scoping, realistic qualification schedules, and production continuity planning that reduces procurement risk for program managers and engineering teams.
