Filling: 37 SD 10A or 392 SD 1, or  184 1-kg incendiary or  28 SD 10 frz, or 116  2-kg in-cendiary.

FUZING: 89B; 69E; 69D; charging head Ladekopf MVOV 500-1. Two fuzes and a charging head are used.

CONSTRUCTION. Container is divided along longitudinal axis into two halves hinged at the tail. The nose compartment contains the fuze assembly, the central compartment accommodates the bombs, and the tail compartment being empty, forms part of the tail structure. A metal strip is welded to one-half container and forms a spigot for the two halves to close on. A pressed metal plate having a central channel runs the length of the central compartment. (See fig. 111.)

The internal structure varies as to bombs carried. When SD 10 frz bombs are carried, they are loosely packed. Fifteen bombs are carried in rear of central compartment and thriteen forward. They are not secured by bands. Containers for SD 10A bombs are divi-ded internally into two compartments. The central compartment of the container is divi-ded into two halves by a plywood sheet. Eighteen bombs are accommodated in the for-ward half and nineteen bombs in the rear half. Each cluster is secured by steel bands which clip into the channel on one side and are wedged in by the wood strip. On the other side the bands are secured together by split pins which pass through loops at the ends. Metal strips looped around the steel bands split the pins. Wooden packing blocks are recessed to receive the bands. In the forward compartment the cluster of bombs is divided by slats of wood and the suspension strut.

The sheet metal tail fins of each half are braced by a bar welded between then.

The charging head Ladekopf MVOV 500-1 is housed in a steel block welded to the con-tainer wall about midway down. A four-core electric cable from the charging head to the nose is carried in a metal tube welded to the inner wall. The cable enters the nose com-partment through a hole drilled in the forward bulkhead. The fuze pocket is located in the nose by two brackets and welded to the forward bulkhead and sides of the container. The lower end of the pocket receives the anvil retained by the shear wire. A tubular ex-tension to the anvil is arranged to receive the bolt, which secures the closed container after assembly. Welded to the side of the fuze pocket is a short length of tube which contains the Z 69 E fuze; the byonet fitting three pin plug closes this tube and connects the fuze with the charging head. A Zt (89) B fuze is held in the fuze pocket by usual locking and locating rings and is connected to the charging head by a charging attach-ment. Access to the fuze assembly is gained by a hole cut in the wall of the nose, and closed by a cap having a bayonet fitting.

OPERATION. On release from aircraft, an electrical charge is transmitted via the charg-ing head to either or both fuze. After a predetermined dealy, depending on the fuze se-lected, fuze operates to detonate the bursting charge. This overcomes the shear wire and forces anvil from fuze pocket. The two halves of the container swing back on the hinge and contents spill out.

In containers filled with SD 1's the 69 D has been painted out and a wooden plug repla-ces the 69 D fuze.
