On November 18, 1927 a drawing was issued detailing the new national insignia for the SAAF which reflected the colour of the new national flag to be introduced on May 31. 1928. This was a roundel with circles in equal widths with the centre in Orange, middle circle in White and outer circle in Blue (Ultramarine). The rudder stripes were marked in the same colours with the blue leading and bands being equal.
As before, roundels were marked on both wings, above and below, as well as on the fuselage. This style of roundel was later referred to as the Type "D" roundel.

These roundels remained standard on SAAF aircraft until WWII with only occasional aircraft wearing the Type ' A' roundel in Orange/white/blue, usually deliveries from Britain, such as the Hawker Furies which has been painted there before delivery and most other Hawker biplanes.
