What publication governs HERO (Hazards of Electromagnetic Radiation to Ordnance)?

The publication that governs HERO (Hazards of Electromagnetic Radiation to Ordnance) is OPNAV 3565. This instruction provides guidance on managing the risks associated with electromagnetic radiation that might affect ordnance safety. HERO is a critical aspect of ordnance management as it outlines the necessary safety protocols and procedures to ensure that radar, radio, and other electromagnetic emissions do not pose a threat to munitions safety during operations.

While other documents, such as NAVSEA 8010, address other aspects of ordnance safety or different safety protocols, they do not specifically focus on HERO. COMNAVSURFPACINST 3520.2 and AFMAN 91-201 cover distinct operational safety guidelines and procedures in various contexts but are not the authoritative references for HERO. Therefore, OPNAV 3565 is the correct publication for governing HERO.
