AND I.J.A.A.F. Aircraft Ordinance
to the Japanese Navy, the Army system of bombs and markings was quite
simple. This simplicity was probably due to the land type targets they were
directed against. Of the bombs dropped, roughly 10% failed to detonate.
These "Duds" were eagerly examined by ordinance experts, if in
fact one can eagerly examine a live rattlesnake's fangs.
of the Amy bombs was quite simple. They used screw-on or screw attached nose
sections. Sheet metal tail assemblies were welded an to the body and tail
fins were spot welded in place. Tail fins were of three types; solid, ie
15kg Type 96; open, ie 1/2kg Type 99; and finally closed, ie 250kg. (Click

with casing simplicity, Army coloration was also simple. Nose, body and tail
coloration was Black. A red nose band was painted on once the high explosive
was filled. A White, 1" band was located just forward of the suspension
lug. Most sources indicate this band denoted a high grade steel casing,
later in the wax the White band was sometimes left off. Forward of the Unite
band, a Yellow band, again 1", was used to denote a Piric
bursting charge. The overall color of the 15kg fragmentation type was Dark
Blue Grey. While other body and band colors were used on special types of
weapons these will be covered in a future article.
topic which will be covered later is fuzes, over 20 Army and Navy nose and
mast units covered here are of known use, the 1/2 kg bomb is a bit of an
enigma. Documents indicate it might be a cluster bomblet, however no casings
were located. The units examined were found in sealed boxes. It is quite
possible this 1939 vintage weapon was in fact a hand thrown weapon either to
mark or harass.
informational markings were in White, and the standard practice was to
stencil the bomb weight, in kg, an top, just forward of the Yellow band.
Mile I can't help with the exact shades of Yellow, Orange and Black the 15
kg was probably Blue Black, possibly FS 35045. The Red however, was the
standard Red used for primer coats, unit markings and Hinomaru, a close
match to FS 31136 when freshly painted.
