PRACTICE BOMB SIGNAL
CARTRIDGES
LEARNING OBJECTIVE: Identify the pur-
pose and use of practice bomb signal car-
tridges.
Practice bomb signal cartridges are used for day
and night operations and as a visual indication of bomb
impact and fuze function. Three types of signal
cartridges are discussed in this section.
Mk 4 Mod 3 signal cartridge. The Mk 4 Mod 3
practice bomb signal cartridge (fig. 4-11) consists of an
aluminum case. The rim end has a percussion primer,
and the opposite end is sealed with an aluminum disk.
The cartridge produces a flash of light and a white
smoke puff. The Mk 4 Mod 3 is primarily used for night
operations.
CXU-3A/B signal cartridge. The CXU-3A/B
practice bomb signal cartridge (fig. 4-12) consists of a
cylindrical aluminum case. The case is closed on one
end with a percussion primer, and the opposite end is
closed with a crimped-in-place aluminum cover (cap).
The cartridge produces a dense, white smoke display
for day missions.
CXU-4/B spotting charge. The CXU-4/B spotting
charge (fig. 4-13) is a fire-free signal used with practice
bomb BDU 45/B to provide a daytime visual indication
of bomb impact point and fuse function.
