bombs by a blue band around the nose and by the 1-inch
letters INERT stenciled on the outside of the bomb body.
The Mk 89 Mod 0 bomb spotting charge adapter
(fig. 1-44) is designed for use in the tail fuze well of the
Mk 80 (series) LDGP inert bombs. A practice bomb
signal cartridge is installed in the Mk 89 Mod 0, which
provides visual observation (smoke) of weapon-target
impact.
The bomb spotting charge adapter is kept in a safe
condition during ground handling by the installation of
a safety cotter pin in the safety pin sleeve. Once the
arming wire has been installed through the arming wire
hole in the safety pin sleeve, the safety cotter pin must
be removed.
LASER GUIDED TRAINING
ROUND (LGTR)
The LGTR (fig. 1-45) is designed to provide
realistic laser guided bomb (LGB) tactical training. The
training round consists of a guidance and control
section, pneumatic controls for moveable control
surfaces, power supply, and a standard practice bomb
signal cartridge. Once initiated, the system cannot be
reset. The signal cartridge (spotting charge) is impact
initiated and does not require safety or cotter pins.
