Nose fuze - Type S

The body consists of a thin metal cylinder liner and outer concrete bomb body, which is reinforced with sheet pellets and wire. The body liner has welded to it: (1) the suspen-sion-lug socket which is internally threaded to receive the horizontal suspension lug; (2) four metal vane supports which have riveted to them four aluminum-alloy vanes; (3) two pairs of diametrically opposite wire guides for the base-plug retaining wire; (4) the ends of a helical reinforcing wire, 16 S.W.G., which is coiled in three turns and passes through the holes provided in the vane support; and (5) the upper end of a second helical rein-forced wire, 8 S.W.G., which is coiled in five turns and welded at its other end to the fuze pocket. The body-liner closing disc is drilled centrally and has pressed to it the fuze pocket. At the upper end, the liner is closed by a cork plug. This bomb is used in con-junction with chemical bombs. The purpose is to indicate the force and direction of the wind at ground level. Two main fillings are used, a smoke filling for use in the day-time, and an incendiary filling for use at night. The night filling is the 1-kg in-cendiary Bomb Type II. Another modification of this bomb has no body liner but is all concrete and is used for practice.
