Bomb Markings

Can any one explain what the yellow rings on the nose of bombs signify? Most pictures I have seen show some bombs with one or two yellow rings and some with no yellow rings.
Thanks ,
Don S.

    Yellow bands on an olive drab piece of ordnance indicate "Explosive filling, High Explosive" in US WWII schemes, be it a bomb or an artillery shell.
     
    Many period photos show the bands rendered invisible by a layer of mud from storage and handling, others show extra yellow lines painted on, particularly from the front ring to the nose fuse socket.
     
    Hope that helps,
    Paul

    The bomb is Dark Green, which was (and still is) standard for British "live" bombs, the yellow ring around the front indicates High Explosive (HE) filling. ...

     US markings are similar.

    As noted, yellow banding indicates HE. Number of bands indicate HE filler composition (attached). -Adrian

    Yes it's correct that the yellow rings reflect HE, but they also indicate what the bomb's explosive filler. The one thing that I learned from working in a bomb dump at Bien Hoa AB, RVN was how critical knowing what the filler was. This was a result that some of the fillers were more sensitive to shock. I don't know if this a NATO standard, but assume that it is.
     
    Using the attached images as an example of what their fillers are would go like this:
    Bomb number one's single yellow ring indicates that it's filled with TNT
    Bomb number two's double yellow rings indicates that it's filled with Comp B.
    Bomb number three's triple yellow rings indicates that it's filled with Tritonal.
    Of the three fillers, Tritonal is preferred for safety reasons and its brisance which is the shattering capability of an explosive. Brisance is simply the  measure of the rapidity with which an explosive develops its maximum pressure or explosive force.
