What does the National Search and Rescue Supplement (NSS) supplement?

The National Search and Rescue Supplement (NSS) serves to supplement the IAMSAR Manual, which stands for the International Aeronautical and Maritime Search and Rescue Manual. This relationship is crucial because the IAMSAR Manual provides global guidance on search and rescue operations and the NSS tailors that guidance specifically for the United States' operational context. It elaborates on the specific roles, responsibilities, and procedures that U.S. entities need to follow, ensuring that these fit within the larger framework of international standards set forth in the IAMSAR Manual.

By focusing on the unique operational needs and resources of the United States, the NSS enhances the overall effectiveness and coordination of search and rescue efforts domestically. This ensures that U.S. SAR operations are aligned with international practices while being responsive to local requirements.
