The drawing for Measure 32 Design 9F for the USS Albireo (AK-90) and cargo ships using the (EC2-S-C1) maritime hull dated May 27, 1944. This drawing specifies vertical colors of light gray (5-L), ocean gray (5-O), and dull black (BK) with pale gray (5-P) on the upper masts and booms and the horizontal color of deck blue (20-B). This drawing has a single waterline, the load waterline, so some ships may have painted camouflage below that line.
This is the only drawing for Design 9F that has yet been found.
