forward adapter assembly, guidance fins, and hardware
required for assembly of laser-guided weapons.
The CCG mounts on the nose of the bomb body (this
precludes the use of nose fuzing). The CCG detects a
laser-illuminated target and provides weapon guidance
signals to the moveable guidance fins.
The guidance fins (canards) attach to the CCG and
the forward adapter assembly. The canards react to the
signals received from the CCG to direct the weapon to
the target. The canards are issued with fin extenders,
which may be snapped off if wing extenders are not
required.
The wing assembly is mounted on the aft end of the
bomb body. It adds necessary aerodynamic stability and
lift for in-flight maneuvering. An electric tail fuze is
installed in the tail of the bomb.
Except for the glass nose of the CCG, all
components are painted olive drab, and the bomb body
has standard LDGP markings.
GBU-24B/B
The GBU-24B/B (fig. 1-34) is a converted
BLU-109A/B 2000 pound class bomb designated as a
hard target penetrator (HTP). The associated
components required for conversion are fuze, air-foil
group, FZU generator, adapter group, and guidance
control unit. The heavy walled case of the bomb
provides the penetration capability of 4 to 6 feet of
reinforced concrete. The GBU-24B/B has a thermal
protective coating applied to the surface to extend the
cook-off time. The GBU-24B/B must not be missing
more than 20 square inches of thermal coating in a single
area or more than 40 square inches total.
