V-weapons, known in original German as Vergeltungswaffen (German pronunciation: [fɐˈgɛltʊŋsˌvafṇ], German: "retaliatory weapons", "reprisal weapons"), were a particular set of long-range artillery weapons designed for strategic bombing during World War II, particularly strategic bombing and/or aerial bombing of cities. They were the V-1, a pulsejet-powered cruise missile; the V-2, a liquid-fueled ballistic missile (often referred to as V1 and V2); and the V-3 cannon. Germany intended to use all of these weapons in a military campaign against Britain, though only the V-1 and V-2 were so used in a campaign conducted 1944–45. After the invasion of western Europe by the Allies, these weapons were also employed against targets on the mainland of Europe, mainly in France and Belgium. Strategic bombing with V-weapons killed approximately 18,000 people, mostly civilians. The cities of London, Antwerp and Liège were the main targets.

V-weapons formed part of the range of the so-called Wunderwaffen (superweapons, or "wonderweapons") of Nazi Germany.
