Figure 1-37.—Mk 89 Mod 0 bomb spotting charge adapter

fuzes is not desired, a Mk 89 Mod 0 bomb spotting charge adapter can be installed in the tail fuze well of the practice bomb to provide visual observation of weapon/target impact. The Mk 80 (series) inert LDGP bombs are painted blue. The new Mk 80 (series) inert LDGP bombs have an olive-drab colored exterior and are thermally protected, but they can be distinguished from service 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. 1-37) 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. 1-38) 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. 1-40 Figure 1-37.—Mk 89 Mod 0 bomb spotting charge adapter.
