English: Two U.S. Navy Douglas A-4C Skyhawk aircraft of Attack Squadron VA-113 Stingers on the catapult of the aircraft carrier USS Kitty Hawk (CVA-63) during that carrier's deployment to Vietnam from 19 October 1965 to 13 June 1966. The U.S. Navy experimented with aircraft camouflage and painted half of the aircraft of Attack Carrier Air Wing 11 (CVW-11) with dark green colours to blend in with the Vietnamese jungle. The results proved inconclusive for the U.S. Navy, whereas the U.S. Air Force concluded that the camouflage was effective. U.S. Navy planes would not be camouflaged until the 1980s. Note that oil from the engine oil breather has streaked the camouflage paint.
