(1) STANDARD IGLOO magazines are an older design. They are not practical for storage of
large missiles and rockets or palletized and containerized ammunition. The door is too small
to admit entrance of a standard 40 by 48-inch pallet moved by a forklift. This type of
magazine is obsolete and has been, or is being replaced by the newer type magazines.
(2) STEEL ARCH magazines have the same inside round walls as the igloo magazine. The
inside looks like the inside of a Quonset hut. They have semi-cylindrical metal walls and
ceiling, a concrete floor, and a door wide enough to handle pallets. Missile containers can
be moved into these magazines.
(3) STRADLEY-YURT magazines are built of reinforced concrete with a wide door or double
door to accommodate the present day ammunition packaging. Forklifts can easily go in and
out with pallets and missile containers. Because of the straight side design of the Stradley-
Yurt, it can be used to store nearly 25 percent more ammunition than standard igloo or steel
arch type magazines of similar size.
(4) The sizes of earth-covered magazines vary, but some common specifications are listed
below. Remember, earth-covered magazines provide the BEST storage for ammunition.
Standard Igloo - 26 feet 6 inches wide by 12 feet 9 inches high by 40, 60, or 80 feet in
Steel Arch - 25 feet wide by 10 feet high by 40 or 64 feet in length.
Stradley-Yurt - 20 feet wide by 14 feet high by 40, 60, or 80 feet in length.
b. Aboveground Magazines.
(1) Standard magazines (Figure 2) are made with steel and concrete frames and have hollow
tile walls filled with sand. They have concrete floors sometimes covered with sparkproof
topping. The largest standard magazines are about 51 feet wide by 218 feet long. Standard
magazines were originally designed to store fixed and separate loading projectiles. For
future use, they should be restricted to storage of classes 1.2, 1.3, and 1.4.
