Above-Ground Magazines
Standard above-ground magazines (Figure 3) are made with steel and concrete frames and have
hollow tile walls filled with sand. Their concrete floors are sometimes covered with a sparkproof
surface. Designed to store 155mm and 8-inch separate loading projectiles, they usually have small-
arms ammunition, firing devices, and other less explosive or less hazardous items stored in them. The
largest above-ground magazines are about 51 feet wide by 218 feet long.
