The V-1 Flying Bomb, also known as the "buzz bomb," was an early cruise missile developed by Nazi Germany during World War II. It was designed to carry explosives over long distances and was launched from ground sites or aircraft. The V-1 had a distinctive pulsejet engine that produced a characteristic buzzing sound, which gave it its nickname. The V-1 was primarily used against targets in London and other cities, causing significant destruction and civilian casualties. Its development marked a significant advancement in guided missile technology, influencing future missile designs and warfare strategies.
