This book supplements previous reference works produced by the Air Force Historical Research Agency through the Air Force History Support Office for Air Force and general public use. These works include publications about Air Force organizations, unit lineage and honors histories, air bases, campaigns, chronologies, contingencies, and aerial victory credits. These materials provide data for those who will make decisions about future Air Force structures and operations and for service members who need reference information about the past. The present volume covers an often overlooked category of Air Force operations: humanitarian airlift. The USAF has participated in hundreds of major humanitarian airlift operations since its birth. These airlifts have saved the lives of thousands of people in the United States and abroad and have served as tools of U.S. diplomacy, demonstrating the versatility of air power not only as a weapon of war but also as an instrument of peace. The future will continue to demand humanitarian airlift operations, and this book will help planners to appreciate, in quantitative and qualitative terms, how these operations were conducted in the past. Historians have written extensively about the United States Air Force as an instrument of war, focusing on aerial combat, bombing, strafing, and the transportation of troops and weapons. They have written less about the role of the USAF in supporting disaster relief operations, in helping emerging nations meet the needs of their citizens, and in feeding the hungry anywhere in the world- missions which are cumulatively known as humanitarian airlift. One might even think this is a new role for the U.S. military. This book attempts to fill a historical gap by addressing humanitarian airlift missions as an important part of Air Force heritage. Rarely acting alone in conducting humanitarian relief efforts, the U.S. Air Force has served with the U.S. Army, Navy, Marine Corps, and Coast Guard. It has worked with other federal agencies such as the Federal Emergency Management Agency, the State Department, and the Agency for International Development. It has also interacted with private charitable organizations. Air Force humanitarian airlift operations include providing assistance at home and abroad. In the event of a domestic disaster, the federal government follows a procedure first defined by the Federal Disaster Act of 1950. After an emergency, a governor requests federal assistance and the president declares the region a federal disaster area. In recent decades, the Federal Emergency Management Agency has coordinated domestic disaster relief, often requesting the support of the Department of Defense for airlift missions. In the case of an international disaster, a foreign government requests relief through the U.S. embassy, permitting the State Department's Agency for International Development and its Office of Foreign Disaster Assistance to coordinate the relief effort. Both organizations have used the USAF for airlift when commercial aircraft were not available or could not perform the mission. In recent years, the Department of Defense established its own office of humanitarian assistance to coordinate congressionally-mandated transport of privately donated relief supplies and distribution of excess nonlethal Defense Department cargo. The Military Airlift Command dominated, but did not monopolize, humanitarian airlifts during the Cold War. Other Air Force commands, such as U.S. Air Forces in Europe, Pacific Air Forces, Tactical Air Command, Alaskan Air Command, Caribbean Air Command, Southern Air Command, and Air Mobility Command took part in significant relief flights. Air Force Reserve and Air National Guard crews and aircraft also participated in many operations, either independently or by complementing active organizations.
