The Operation Bellicose strategic bombing in World War II targeted the Nazi Germany Zeppelin Works in Friedrichshafen and the La Spezia, Italy, naval base and was the first use of shuttle bombing in World War II and the second use of a Master Bomber. In early June 1943, a Central Interpretation Unit photo interpreter (Claude Wavell) identified a stack of ribbed baskets (Würzburg radar reflectors) at the Zeppelin Works. After Winston Churchill viewed the photos at RAF Medmenham on June 14, No. 5 Group RAF received the surprise orders on June 16 to attack Friedrichshafen during the next full moon.
