It was hoped that the 15th AF – stationed in the Mediterranean – would be able to operate when the Eighth Air Force (8th AF) in England was socked in by bad English weather. The 9th AF would later move to England to serve as a tactical unit to take part in the invasion of Europe. Once bases around Foggia in Italy became available, the 15th was able to reach targets in southern France, Germany, Poland, Czechoslovakia, and the Balkans, some of which were difficult to reach from England.
