HTK-AS53 Early US Navy & USMC paint set
Standard camouflage colours of US naval planes from 1919 till 1942
After end of WW1 US naval aviation (both US Navy and US Marines) adopted a standard aircraft camouflage of overall Aluminium Dope, initially supplemented by Naval Aircraft Grey on all metal parts (ruled out in mid-1930, when aluminium paint provided enough anticorrosion protection). Orange Yellow was used as high-viz feature on upper wing surface.
In 1941 a new scheme was implemented of overall NS Light Grey. It remained in use only for 10 months, replaced by final pre-WW2 scheme of NS Sea Grey / Blue Grey over NS Light Grey.
