Orange Herald (small) warhead prepared for test at the Christmas Island Grapple series on 31 May 1957. Yield was 720 kT. The spherical implosion device is seen in this photograph housed in the centre section of a Blue Danube carcass with the nose, tail and panelling removed.

Each of the 32 firing cables was duplicated.
