SUU-58/B Subsonic Free-Fall Dispenser

Mod 1 fuze, Kit Modification Unit KMU-428/B, and 60 mines (45 BLU-91/B and 15 BLU-92/B). The fuze initiation time is preset and is activated upon weapon release from the aircraft. Fuze time settings are primary mode (1.2 seconds) and option mode (4.0 seconds). The KMU-428/B adapts the mines to the dispenser; it also provides mine activation/self-destruct time selection. SUU-58/B Subsonic Free-Fall Dispenser The SUU-58/B consists of a cargo section with a nose fairing assembly attached, a tail cone assembly, and fuze arming wires with extractors. There are two observation windows—one for viewing the safe/arm indicator and the other to observe the fuze time-setting dials. The cargo section houses the BLU-91/B and BLU-92/B mines. The tactical weapons have two yellow bands around the nose cone fairing. BLU-91/B and BLU-92/B Mines The target sensors are the primary difference between the two mines. The BLU-91/B uses an armor-piercing warhead and a magnetometer type of sensor; the BLU-92/B has a fragment type of warhead with trip wires as the primary target sensor. PRACTICE BOMBS LEARNING OBJECTIVE: Identify the different types, purpose, and use of practice bombs to include subcaliber and full-scale practice bombs. Practice bombs are used to simulate the same ballistic properties of service bombs. Practice bombs are manufactured as either solid or cast-metal bodies. Since practice bombs contain no explosive filler, a practice bomb signal cartridge (smoke) can be used for visual observation of weapon-target impact. The primary purpose of practice bombs is safety when training new or inexperienced pilots and ground-handling crews. Other advantages of practice bombs include their low cost and an increase in available target locations. 1-37 Figure 1-33.—CBU-78/B and B/B GATOR weapon.
