Sea Service Ribbon, Navy

A Sea Service Ribbon is an award of the United States Navy, United States Marine Corps, United States Coast Guard, the United States Army, and the National Oceanographic and Atmospheric Administration which recognizes those service members who have performed military duty while stationed on a United States Navy, Coast Guard, Army, or NOAA vessel at sea and/or members of the Navy, Marine Corps or Coast Guard who have been forward-deployed with their home unit.
The Sea Service Deployment Ribbon (SSDR) is a service award of the United States Navy and United States Marine Corps which was authorized in May 1980 and retroactively authorized to 15 August 1974, coinciding with a temporary suspension in authority for award of the National Defense Service Medal between that date and 2 August 1990. It was the first type of sea service ribbon established in the U.S. Armed Forces.
