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

Mechanism

At first glance it seems unlikely 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 to disguise ships in all weather.

Dazzle did not conceal the ship but made it difficult for the enemy to estimate its type, size, speed and heading. The idea was to disrupt the visual rangefinders used for naval artillery. Its purpose was confusion rather than concealment.[1] An observer would find it difficult to know exactly whether the stern or the bow is in view; and it would be equally difficult to estimate whether the observed vessel is moving towards or away from the observer's position.[2]

The rangefinders were based on the co-incidence principle with an optical mechanism, operated by a human to compute the range. The operator adjusted the mechanism until two half-images of the target lined up in a complete picture. Dazzle was intended to make that hard because clashing patterns looked abnormal even when the two halves were aligned. This became more important when submarine periscopes included similar rangefinders. As an additional feature, the dazzle pattern usually included a false bow wave to make estimation of the ship's speed difficult.

The demonstrable effectiveness of the bold Dazzle camouflage was accepted by the Admiralty, even without practical visual assessment protocols for improving performance by modifying designs and colours.[3] The Dazzle camouflage strategy was adopted by other navies. This led to more scientific studies of colour options which might enhance camouflage effectiveness. Broken colour systems which present units so small as to be invisible as such at the distances considered are neither advantageous or detrimental. The visibility of the camouflaged vessel would depend entirely upon such scientifically measurable factors as the mean effective reflection factor, hue and saturation of the surface when considered at various distances.[4]

In the UK, the British Army introduced its Camouflage Section at the end of 1916: while at sea, the marine painter Norman Wilkinson invented the concept of “dazzle painting” — a way of using stripes and disrupted lines to confuse the enemy about the speed and dimensions of a ship.[5] Wilkinson, then a lieutenant commander on Royal Navy patrol duty, implemented the precursor of "dazzle" on SS Industry; and HMS Alsatian became the first Navy ship in August 1917.

All British patterns were different, first tested on small wooden models viewed through a periscope in a studio. Most of the model designs were painted by women 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 including sculptors, abstract artists, and set designers designed camouflage.[6]

The Vorticist artist Edward Wadsworth supervised the camouflage of over two thousand warships, and his post-war canvases celebrated his dazzling ships.

World War I

Dazzle's effectiveness is not certain. The British Admiralty concluded it had no effect on submarine attacks, but proved to be a morale boost for crews. It also increased the morale of people not involved in fighting; hundreds of wonderfully coloured ships in dock was nothing ever seen before or since.

In a 1919 lecture, Norman Wilkinson explained:

The primary object of this scheme was not 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. [Dazzle was 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.

During both World Wars, former ocean liners owned by British steamship companies like Cunard Line were re-commissioned as an integral part of the British fleet. These auxiliary vessels were re-fitted with armament and re-painted in the same manner as other fleet ships. For example, this meant that the former Canadian Pacific Steamships passenger liner, the RMS Empress of Russia, was given the "dazzle" treatment when she was converted into a troopship.

World War II

American naval leadership thought dazzle effective. In 1918, the U.S. Navy adopted it, as one of several techniques.

Dazzle continued to be used until the end of World War II.

However effective the scheme was in World War I, it became less useful as rangefinders and especially aircraft became more advanced, and, by the time it was put to use again in World War II, radar further reduced its effectiveness. However, it may still have confounded submarines.

The US Navy implemented a camouflage painting program for all Tennessee-class battleships and some Essex-class aircraft carriers in World War II. The designs were not arbitrary, but were standardised in a process which involved a planning stage, then a review, and then fleet-wide implementation.

Art history

Winston Churchill considered deception in war to be an indispensable "element of léger de main, an original and sinister touch, which leaves the enemy puzzled as well as beaten."[7]

In 2007, the art of concealment was featured as the theme for a show at the Imperial War Museum. The evolution of Dazzle was re-examined in this context. Picasso is reported to have taken credit for the modern camouflage experiments which seemed to him a quintessentially Cubist technique.[8] He is reported to have drawn the connection in a conversation with Gertrude Stein shortly after he first saw a painted cannon trundling through the streets of Paris.[2]

In 2008, the Fleet Library at the Rhode Island School of Design announced the rediscovery in its collection of 455 lithographic printed plans for the camouflage of US merchant ships during World War I. These documents were donated to the RISD library in 1919 by one of the school’s alumni, designer Maurice L. Freeman, who had been a camouflage artist for the U.S. Shipping Board in Jacksonville, Florida. Portions of the collection were publicly shown at the RISD library for the first time from January 26 through March 29, 2009, in an exhibition titled "Bedazzled."

Modern use

In modern times, dazzle camouflage is seldomly used. In Austria, speed traps have been camouflaged with dazzle to confuse drivers in which direction the radar is pointing (see image to the right).
