Why ships used this camouflage in World War I

Dazzle camouflage was a surprisingly effective defense against torpedoes. In this episode of Vox Almanac, Phil Edwards explains why. World War I ships faced a unique problem. The u-boat was a new threat at the time, and its torpedoes were deadly. That led artist Norman Wilkinson to come up with dazzle camouflage (sometimes called “razzle dazzle camouflage”). The idea was to confuse u-boats about a ship’s course, rather than try to conceal its presence. In doing so, dazzle camouflage could keep torpedoes from hitting the boat — and that and other strategies proved a boon in World War I.
