Air forces of the United Nations Command carried out an extensive bombing campaign against North Korea from 1950 to 1953 during the Korean War. It was the first major bombing campaign for the United States Air Force (USAF) since its inception in 1947 from the United States Army Air Forces (USAAF). During the campaign, conventional weapons such as explosives, incendiary bombs, and napalm destroyed nearly all of the country's cities and towns, including an estimated 85 percent of its buildings.[1]
