Dazzle camouflage Totally Explained

Everything about Dazzle Camouflage totally explained

Dazzle camouflage, also known as Razzle Dazzle or Dazzle painting, was a camouflage paint scheme used on ships, mainly during World War I. Credited to artist Norman Wilkinson, it consisted of a complex pattern of geometric shapes in contrasting colors, interrupting and intersecting each other.

Mechanism

At first glance it seems like an unlikely form of camouflage, drawing attention to the ship rather than hiding it but this technique was developed after the Allied Navy's failure to develop effective means of disguising ships in all weather conditions. Dazzle therefore had a very specific purpose which wasn't to conceal the ship but to make it difficult for the enemy to estimate the target ship's speed and heading. In doing so the idea was to disrupt the performance of the visual rangefinders used for naval artillery at the time. In other words, its purpose was confusion, rather than concealment.
   The rangefinders were based on the co-incidence principle with an optical mechanism, operated by a human being to compute the range. The operator adjusted the mechanism until two half-images of the target displayed lined up into a complete picture. Dazzle camouflage was intended to make it hard to do this job because the clashing patterns would look abnormal even when the two halves were correctly aligned. This became even more important when submarine periscopes were developed which included similar rangefinders. As an additional feature, the dazzle pattern usually included a "false bow wave" painted on which was intended to make a true estimation of the ship's speed difficult.
   Invented by the artist Norman Wilkinson, who served as a Lieutenant Commander on Royal Navy patrol duty, dazzle camouflage was first implemented on the merchant ship SS Industry, and HMS Alsatian became the first dazzle painted Navy ship in August 1917. The U.S. Navy adopted it, as one of several approved techniques, the next year.
   All British patterns were different, and were first tested on small wooden models viewed through a periscope in a studio. Most of the model designs were painted by women artists from London's Royal Academy of Arts. A foreman then scaled up their designs for the real thing. Painters, however, were not alone in the project. Creative people of all types including sculptors, abstract artists, and set designers served their countries by designing camouflage.

Effectiveness

Dazzle camouflage's effectiveness isn't entirely certain. The British Admiralty eventually came to the conclusion that the scheme had no material effect on submarine attacks, but proved to be a morale boost for crews. It also served to increase the morale of people who were not involved in fighting, the sight of hundreds of wonderfully coloured ships in dock was like nothing ever seen before (or since). American naval leadership expressed the dissenting opinion that dazzle camouflage was effective. Dazzle camouflage continued to be used until the end of World War II. However effective the scheme was in WWI, it eventually became largely obsolete as rangefinders became more advanced, and, by the time it was put to use again in WWII, the introduction of radar soon made it essentially useless in defeating naval gunnery. However, it may still have possessed some effect in confounding submarines. In a 1919 lecture, Norman Wilkinson explained: ť "The primary object of this scheme wasn't so much to cause the enemy to miss his shot when actually in firing position, but to mislead him, when the ship was first sighted, as to the correct position to take up. [Dazzlewas a] method to produce an effect by paint in such a way that all accepted forms of a ship are broken up by masses of strongly contrasted colour, consequently making it a matter of difficulty for a submarine to decide on the exact course of the vessel to be attacked.... The colours mostly in use were black, white, blue and green.... When making a design for a vessel, vertical lines were largely avoided. Sloping lines, curves and stripes are by far the best and give greater distortion."
