Fuzing:
BSB 360, cable release.
BSB 700, electrical solenoid release.

CONSTRUCTION. The BSB 360 is a sheet steel cylinder with a blunt nose and tapered tail section. The cylinder is divided into four compartments, each containing eight bombs. The two doors of the container are opened manually by a cable, each door opening two compartments and releasing bombs in groups of 180. This container generally remains in the aircraft after dropping the load.

SUSPENSION. Horizontal. Container retained in plane.

COLOR. Black over-all.

CONSTRUCTION. The BSB 700 is a sheet steel cylinder with a blunt nose and conical tail section. Cylinder has six compartments, each containing 117 bombs. The contents of each compartment are released by means of trap doors operated from an axial spindle, the release mechanism being controlled electrically through a solenoid. Bombs are relea-sed in batches of 69 and 48 from each compartment. Each compartment has an expen-dable outer door and inner rotating door (rotated by action of the solenoid). This contai-ner remains in the aircraft after dropping the load.

SUSPENSION. Horizontal. Container remains with plane.

COLOR AND MARKINGS. Black over-all. Stenciled on bomb body:

CONSTRUCTION. The BSB 1000 has a sheet steel cylindrical body. The blunt nose and conical tail section are attached by bolts and rivets. The nose and tail sections are re-cessed to take a transport loading bar. The main body is internally divided along its long-itudinal axis by a hollow central bilkhead which houses the release rods. Each half of the main body is further divided into 5 compartments by bulkheads, thus making 10 compart-ments. The spring loaded compartment doors are hinged to the underside of the contai-ner. These doors are held by hook releases which are connected by the release rod to the electrical release units fitted with manually operated release switches for use in loading. No fuze is fitted and it is assumed that the electrical lead passes into the junc-tion box and selection mechanism housed in the tail, the latter functions to space that 570 bombs as desired. In operation, the electrical charge passes through the junction box and causes the selector mechanism to function. Current is passed to release units, and these open the release hooks through the medium of the release rod. The weight of the bomb forces doors open and bombs fall, the spring loaded doors then closing to pre-serve streamlined containers. (See fig. 110.) This container also remains in the aircraft after dropping the load.

SUSPENSION. Horizontal.

COLOR AND MARKINGS. Light khaki or grey over-all. "Leergewicht 210 kg" is stenciled on body.
