Mortar Smoke Bomb
were two types of smoke bombs one filled with smoke composition
(HCE) the other filled with white phosphorous (W.P.). The drill
for using the two types was that a screen as begun with W.P. to
give immediate screening, followed by H.C.E. and gaps filled with
the photograph above you can just make out 3 holes in the tail
fin shaft. In all there were 18 holes around this shaft through
which the smoke or W.P. would escape - there are also four holes
around the base of the tail fin..
smoke bombs were pained green. The red band indicates that it
is filled, an additional white band would indicate W.P. The bombs
were propelled by a ballistic cartridge fitted in the tail.
The flash from the cartridge ignited a priming mixture which in
turn set of the smoke composition itself. A trail of smoke was
by the bomb as it lobbed through the air. The composition itself
would burn for approximately 1.25 minutes.
W.P.: The white phosphorous bombs were fitted with a fuse which
would detonate upon impact. The fuse itself had a protective cap
which was removed prior to firing.
