Photo Northrop BT – 17: In 1940 the USN experimented with a new camouflage for its aircraft. The basic designs were drawn by McClelland Barclay. He used outlandish circles, stripes, and trapezoid shapes. The colours used were Deep Blue and Dark Grey for the upper surfaces and Bright Blue and White for the undersurfaces. Two Brewster F2A-2 fighters, two Vought SB2U-2 scout-bombers, two Douglas TBD-1 torpedo bombers and two Northrop BT-1 dive-bombers received the new camouflage schemes, each receiving a different design. On the opposite page a BT-1 (serial unknown) illustrates design No.3 and on this page BT-1 Bu.No 0633 has design No.4. All the pictures were taken at North Island NAS (San Diego) on
9 September 1940.  (see also photo 18 to 22)
