AIRCRAFT BOMB AMMUNITION AND
ASSOCIATED COMPONENTS
LEARNING
OBJECTIVE:
Identify
the
purpose and types of aircraft bombs, the safety
procedures to be followed during bomb
shipment, and the methods used to carry
bombs.
Aircraft bombs are released over enemy targets to
reduce and neutralize the enemy's war potential. This is
done by destructive explosion, fire, nuclear reaction,
and war gases. Aircraft bomb ammunition is used
strategically to destroy installations, armament, and
personnel; and tactically in direct support of our land,
sea, and air forces engaged in offensive or defensive
operations.
For safety reasons, some bomb ammunition is
shipped and stowed without the fuzes or arming
assemblies and associated components installed. This
ammunition must be assembled before use. Other
types, such as cluster bomb units (CBUs), are shipped
and stowed as complete assemblies, with fuzes or
arming assemblies and associated components
installed.
Bombs are designed to be carried either in the
bomb bay of aircraft or externally under the wings or
fuselage. The general characteristics and basic
principles of operation of bomb ammunition and its
associated components are described in this chapter.
Bomb assembly procedures are discussed in chapter 13
of this manual.
GENERAL-PURPOSE BOMBS AND FIN
ASSEMBLIES
LEARNING
OBJECTIVE:
Identify
the
purpose and use of general-purpose bombs to
include shipping configuration, fuze wells and
charging circuits, suspension lugs, arming
wire assemblies, and fin assemblies.
Low-drag, general-purpose (LDGP) bombs are
used in most bombing operations. Their cases (bomb
body) are aerodynamically designed, relatively light,
and approximately 45 percent of their weight are made
of explosives. General-purpose bombs may use both
nose and tail mechanical or electric fuzes and conical or
Snakeye fins.
The general-purpose bombs currently in use are the
LDGP Mk 80 (series). The specifications for the
individual bombs are listed in fig 1-14. The basic
difference between the bombs listed in fig 1-14 is their
size and weight. The following description of the Mk
80 (series) bomb is applicable to all bombs within the
Mk 80 (series) unless otherwise noted.
SHIPPING CONFIGURATION
The bomb body (fig. 1-15) is shipped with a plastic
plug installed in the nose and tail fuze well to prevent
damage to the internal threads and to keep out moisture.
The aft end of the bomb body has a metal shipping cap
installed. Plastic lug caps are installed in the suspension
lug wells, and a plastic plug is installed in the
fuze-charging receptacle well. Some bombs contain a
hoisting lug packaged in the tail fuze well.
Bombs are shipped on metal pallets. The number of
bombs loaded on each pallet depends on the bomb size.
For example, six Mk 82 bombs can be shipped on a
pallet, three Mk 83 bombs can be shipped on a pallet,
and two Mk 84 bombs can be shipped on a pallet. Refer
to Airborne Weapons Packaging/Handling/Stowage,
NAVAIR 11-120A-1.1 or appropriate MIL-STD for
more information on shipping configurations.
FUZE WELLS
The bomb body is designed with a nose and tail
fuze well. These wells are internally threaded to receive
either mechanical or electric fuzes.
FUZE CHARGING CIRCUIT
The forward and aft charging tubes are installed at
the factory and contain the electric fuze wire harness.
When electric fuzing is used, the wire harness provides
a path for the charging current from the fuze-charging
receptacle to the forward and aft fuze wells.
SUSPENSION LUGS
There are two suspension lug wells for the
installation of suspension lugs. The suspension lugs are
1-17
