|USS Vestal (1944)|
The photograph above, for example, is not from WWI. It's a camouflaged American ship (the USS Vestal), photographed on September 8, 1944, near the end of WWII. True, this particular design is not typical of US ship camouflage at the time—not because it's disruptively patterned but rather because it's so "squiggly" and non-geometric. In fact, in the overwhelming density of its disruption, it seems more reminiscent of certain German camouflage for minesweepers from the same time period.
The USS Vestal was used in both World Wars (in fact it was one of the ships that was damaged during the attack on Pearl Harbor). As a result, we have the opportunity to compare this ship's WWII camouflage (above) with its earlier camouflage scheme from WWI (below).

Postscript As of 10Aug2016, we have received this information from Aryeh Wetherhorn—
The WWII pattern was called Measure LC. It was a random pattern of Black, Brown, and 3 shades of Green. It was used primarily for amphibious ships, but also for support ships that might be viewed against a jungle island background.
