Hiding Air Bases, Factories and Plants in WWII

It’s February, 1942. US Navy Monitors have just tracked a Japanese submarine skulking just outside of San Francisco. A few nights later, a Japanese submarine surfaces off the coast of Santa Barbara and fires a few shells at an oil storage facility. With the memories of Pearl Harbor from last December still fresh, the threat of a Japanese invasion is palpable.

Enter Lt. Gen. John L. De Witt, head of Western Defense Command. He is tasked with the daunting order to implement ‘passive defense measures’ for all vital installations along the Pacific coast. Executing such an order fell to Col. John F. Ohmer who was stationed at March Field, about 60 miles east of downtown Los Angeles. Camouflage California was on.

Flights over camouflaged areas tested positively as pilots were unable to identify the bases, factories and plants. Soon orders came from other areas of the US. In Seattle, the gigantic 26-acre Boeing Aircraft complex ordered the same treatment, blanketing the plant under netting; disguising the area as a suburb complete with municipal buildings, parks, schools and homes.
