Smithsonian | World War I Ship Camouflage

Smithsonian article on WWI ship camouflage
Above and below World War I government photographs of two of the women camoufleurs, called Yeomen (F) to distinguish them from men, who served in the US Naval Reserve with the Design Subsection of the navy's Camouflage Section. In an attempt to find opportunities for women to participate meaningfully in the war, a small number were allowed to work on ship camouflage.

As shown here, women were only responsible for assembling small wooden ship models, on which camouflage schemes were painted by men, for testing in a periscope-equipped observation theatre. Only the men were allowed to design the actual schemes. Shown here are colorized versions of public domain black and white news photographs (c1918) in the collection of the National Archives and Records Administration.

…In order for a U-boat gunner to fire and hit his target from as far as 1,900 meters away (and not closer than 300 meters, as torpedoes required at least that much running distance to arm), he had to accurately predict where the target would be based on informed guesses. Compounding the difficulty was the fact that he had typically less than 30 seconds to sight the target ship through the periscope, or risk the periscope’s wake being seen and giving away the submarine’s location. Typical U-boats could only carry 12 very expensive and very slow torpedoes at a time, so the gunner had to get it right the first time.

“If you’re hunting for ducks, right, all you have to do is lead the target and it’s a simple process. But if you’re a submarine aiming at a ship, you have to calculate how fast a ship is going, where is it going, and aim the torpedo so that they both get to the same spot at the same time,” says Roy R. Behrens, a professor at the University of Northern Iowa, author of several books on dazzle camouflage and the writer behind the camouflage resource blog Camoupedia

Wilkinson’s idea was to “dazzle” the gunner so that he would either be unable to take the shot with any confidence or spoil it if he did. “Wilkinson said you had to only be 8 to 10 degrees off for the torpedo to miss. And even if it were hit, if [the torpedo] didn’t hit the most vital part, that would be better than being hit directly.”… more>>>
