explosives if enough space is available. Earth-covered magazines include, but are not limited to, the
standard igloo, the steel-arch, and the Stradley (Figure 1).
Figure 1. Earth-covered magazines with some common specifications.
The standard igloo magazine is an older, obsolete design that is not practical for storing large missiles
and rockets in the age of palletization and containerization. The doors are too small to admit a
standard pallet by forklift. The standard igloo magazine has been, or is being replaced by newer type
The steel-arch magazine has the same curved metal inside walls and ceiling as the standard igloo
magazine (Figure 2). It has a concrete floor and a door wide enough to handle pallets and missile
containers. Forklifts can go in and out easily with pallets and missile containers.
The Stradley magazine (see Figure 2) is built of reinforced concrete and has a wide door or double
doors to accommodate the present day ammunition packaging. Because of its straight-side design,
nearly 25 percent more ammunition can be stored in it than in the standard igloo or the steel-arch
magazine of comparable size.
