magazine locations of a typical CV (aircraft carrier). For safety reasons, various types of explosives and ammunition are stowed in separate magazines or lockers. The type of stowage varies with the type of ship, the space available, and the amounts of explosive involved. All magazines are marked by label plates that designate the compartment and the types of ammunition stowed in them. Magazines are marked with warnings that apply to specific special hazardous conditions and operations. Additionally, paint-stenciled labels or painted signs are installed on the outside surfaces of ammunition stowage spaces (except where the outside surfaces are visible from the exterior of the ship). The stenciled markings must be located on the bulkheads, overheads, and decks 12 feet apart. The sign or label (fig. 11-4) is a yellow rectangle, 5 inches high by 9 inches wide. The sign has black slanted lines, 1/8-inch thick and 1 inch long, on 3/4-inch centers along the top and bottom edges, with lines slanting from top right to bottom left. The letters are 1/8-inch thick and 3/4-inch high, with the words AMMUNITION FAR SIDE arranged as shown in figure 11-4. Primary and missile magazines aboard CVs are designed to hold a ship’s service allowance and the embarked air wing’s service allowance of ammunition. Ships have several different types of magazines. Each magazine is designed for a specific type of ammunition. The magazine types include primary, missile, ready-service, lockers, and chemical. Primary Magazines Primary magazines are stowage spaces that are usually located below deck and, if possible, below the waterline. They are adequately equipped with thermal insulation, temperature control, and ventilation. Primary magazines are equipped with adequate sprinkler systems, and they are closed and locked when unattended. Figure 11-4.—Example of AMMUNITION FAR SIDE sign or label. Missile Magazines Because of the nature of guided missiles, requirements for their stowage aboard ship differ from those of conventional ammunition. Air-launched missile magazines in aircraft carriers are usually located below the waterline and within the armor box. Air-launched missile ready-service magazines may be located either above the waterline or within the armor box. Missile magazines contain electrical, hydraulic, and pneumatic power-operated handling equipment. A restraining gear prevents movement of an accidentally ignited motor. Magazines are equipped with specialized detection equipment to make sure that a specific missile hazard isn’t present. You must take special care of the ventilation system of missile magazines to ensure pressures don’t build up to a dangerous level if a missile motor is ignited. Additional fire-fighting equipment is often provided for missile magazines. This equipment may consist of carbon dioxide, foam, water injection, or a sprinkler system, or a combination of these systems. NAVSEASYSCOM specifically certifies the magazine for the stowage of hyperbolic-fueled missiles, such as the AQM-37 target drone and fuel-air explosive (FAE) weapons. FAE weapons and the AQM-37 are compatible in stowage. FAE weapons require less stringent certified facilities; therefore, FAE weapons can be stowed in hyperbolic magazines. However, hyperbolic-fueled items cannot be stowed in magazines certified for FAE only. Ready-Service Magazines Ready-service magazines (fig. 11-5) are designated spaces located near the weapon or area to be served. Normally, they are equipped with thermal insulation, ventilation, and a sprinkling system. They are securely locked. Certain magazines located within the armor box of aircraft carriers and used for stowage of completely assembled rounds of weapons and deployable targets are also ready-service magazines. Lockers Certain compartments or lockers are used to stow special types of ammunition and ammunition components, such as detonators, pyrotechnics, and chemicals. They are frequently located on the weather deck. They are located as conveniently to the weapon or space to be served as possible. They may not be equipped with sprinklers, but they do have locking devices. Special flare ready-service lockers are located 11-8
