It's difficult to hide from an enemy when you're inside an enormous ship, or part of a vast Naval fleet. And yet many ships in history have been well-camouflaged, despite a distinct lack of cloaking devices. Here are some of the most amazing examples.

USS West Mahomet (a steel-hulled cargo ship of the U.S. Navy, 1918-1919, but used as a merchant vessel under the name SS West Mahomet between 1919 and 1930. Scrapped in 1938.)

The beginnings

Between the 16th and the late-19th centuries some ships might had cannon ports hidden by painted canvas, or extra cannon ports painted. In the Civil War and later the German and French ships were being painted gray.

The transatlantic Olympic-class ocean liner RMS Olympic, the brother of the Titanic and Britannic (launched in 1910, used as a troopship between 1915 and 1919. Retired in 1935.)

In 1917 the British Navy added a multi-coloured camouflage to make the ship more difficult to identify and target.

The RMS Olympic was known as "Old Reliable", it would carry over 200,000 troops to and from the fighting fronts during WWI.
