BODY CONSTRUCTION:

This bomb consists of a solid cast iron nose section bored centrally to house a stri-ker head, to which are attached a long striker. A striker guide bush is threaded into the after end of the central bore. A shear wire through the guide bush and the striker pre-vents the striker from contact with the detonator-burster in the unarmed position.

During transit and normal handling, the striker also is retained by a split pin and a spring-loaded safety pin. The split pin is removed when the bomb is loaded aboard the plane, and the safety pin is ejected when the bomb is released.

TAIL CONSTRUCTION:

The tail consists of a long tail cone, closed at the wider end by a central plug. A central tube for the detonator-burster passes through the tail cone. Located in the central plug, slightly off-center, is a filling plug through which the smoke or flash filling is a part of the tail protion of the bomb. A tail tube is attached to the after end of the tail cone and supports a cylindrical shroud and four fins. The central plug is threaded externally and screws into the after end of the cast iron nose section of the bomb.

SUSPENSION:

A single U-shaped suspension lug is provided.

EXPLOSIVE COMPONENTS:

Detonator-burster No. 28 Mk I: 10 grains fulminate of mercury and 7 C.E. pellets.

Smoke Filling, Mk I Bomb: Titanium tetrachlroide.

Flash Filling, Mk III Bomb: Magnesium shavings and gunpowder, or calcium silicide and gunpowder.

REMARKS:

1. The smoke filled bombs are used for daylight operations; the flash filled at night. Because of their solid cast iron noses, these bombs should not be used against lightly armored targets.

2. The Mk I and Mk III bombs are indentical, except for the fillings.
