 11 Squadron Catalina was mistaken for a Japanese aircraft by a US Navy Wildcat in the Pacific Theatre and attacked, the roundels on RAAF were modified, mostly in the field, by painting over the red with white.Often the yellow outer rings of type A1 roundels were left intact.No British or American built aircraft had factory painted SEAC style roundels; all aircraft had to be repainted, and, in many cases re-camouflaged by Maintenance Units behind the lines or by front line squadrons.
