Operation Bellicose strategic bombing in World War II targeted the Nazi Germany Zeppelin Works in Friedrichshafen and the Italian naval base at La Spezia. It was the first shuttle bombing raid 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 14 June, No. 5 Group RAF received the surprise orders on 16 June to attack Friedrichshafen during the next full moon.
