retarded (high-drag) or unretarded (low-drag) bomb
delivery capability for the aircraft. The BSU-86/B fin
is attached to the Mk 82 or BDU-45/B bomb by eight
setscrews. A 25-degree wedge is located at the tips of
each fin to impart spin. The airstream drives the fin
open rapidly, when the MAU- 199/B spring arming wire
(SAW) is activated Fin opening is initiated by the
spring load under each fin blade.

GUIDED BOMB UNITS
LEARNING OBJECTIVE: Identify the
different types, purpose, use, and operation of
guided bomb units.
GBU-12, GBU-16, AND GBU-10
The GBU-12, GBU-16, and GBU-10 guided bomb
units (GBUs) (fig. 1-33) are Mk 82, Mk 83, and Mk 84
LDGP bombs modified to detect a target illuminated by
a laser beam. The modification consists of a MAU-169
series computer control group (CCG) and MXU-650,
651, or 667 series airfoil group (AFG). Each AFG
contains identical items; although they are different in
physical size, they perform identical functions. A
typical AFG is composed of a folding wing assembly,
