device, Mk 59 booster, Mk 42 firing mechanism, and all
necessary hardware (less battery and fin assembly) to
convert an LDGP bomb to an air-laid mine. The firing
mechanism of the Mk 42 arming device requires the use
of a Mk 95 battery, which must be installed during
assembly procedures.
REVIEW NUMBER 5 ANSWERS
A1.
Normally, low-drag general-purpose (LDGP)
bombs are used in bombing operations.
Currently, Mk 80 (series) LDGP bombs are
used.
A2.
Bombs are shipped on metal pallets because
of their increased capacity and for grounding
purposes over wooden pallets.
A3.
The Mk 15 fin is used with the Mk 82 bomb
in
either
a
low-drag
or
high-drag
configuration.
A4.
The ADU-320/B adapter is used to mate the
MAU-91A/B fin to the Mk 83 bomb.
A5.
The three modes of delivery used with
Snakeye fins are the retarded mode, used
during
low-level
bombing;
nonretarded
mode, in which the weapon free falls to the
target; and the in-flight selected mode
(pilot option), where the pilot selects either
the
retarded
or nonretarded mode of
delivery.
REVIEW NUMBER 6 ANSWERS
A1.
Laser-guided
bombs
detect
a
target
illuminated by a laser beam.
A2.
Electrical tail fuzes are used in laser-guided
bombs.
A3.
The wing assembly is mounted on the aft end
of the bomb body to add aerodynamic
stability and lift for in-flight maneuvering.
With the Mk 75 kit installed, a Mk 82 LDGP bomb
(500 pounds) becomes a Mk 36 DST, a Mk 83 LDGP
bomb (1,000 pounds) becomes a Mk 40 DST, and a Mk
84 LDGP bomb (2,000 pounds) becomes a Mk 41 DST.
The Mk 36 and Mk 40 DSTs can be dropped in the
retarded or nonretarded mode of delivery. The
installation of a conical fin provides nonretarded
(free-fall) delivery only. The installation of a Snakeye
fin assembly provides the pilot with the in-flight option
of releasing the DST in the retarded or nonretarded
mode. The Mk 41 DST is configured with a conical fin
for nonretarded delivery only. The standard LDGP
bomb markings plus white stripes (fig. 1-30) identify
DSTs.
Additional information on DSTs may be found in
Destructor Mk 36, 40, and 41, all Mods, NAVSEA OP
3529.
REVIEW NUMBER 7
Q1.

bombs into destructor (DST) mines?
Q2.

destructor.
Q3.
Name the DST that can only be dropped in the
nonretarded mode.

LEARNING
OBJECTIVE:
Identify
the
purpose and use of the various configurations
of the Mk 20, CBU-99, and CBU-100 antitank
bomb clusters. Describe the function of the Mk
118 Mods 0 and 1 antitank bomb.
