FUZING:

British Tail Pistol No. 58 Mk I

BODY CONSTRUCTION:

The body is manufactured in two different ways. The British produced model is of cast steel, with a solid nose plug and with three exploders fitted 120° apart in the tail. The bomb bodies are issued with exploders inserted, and the exploders tubes are seeled with shipping plugs. The eventual American T10 will consist of five sec-tions welded together. The solid nose and base section will be of forged steel, while the three center sections will be fabricated from rolled plate, longitudinally welded, taper-bored internally and the set in a die to form the external contour.

The tail is attached to the after end of the bomb body by 12 studs. A cylindrical metal cowling placed between the bomb body and the tail cone, enhances the streamlining of the bomb.

TAIL CONSTRUCTION:

The special tail unit, No. 78 Mk I, is constructed of light alloy and consists of a cone to which are attached four fins of streamline cross-section. The fins are set an angle of 5° to the axis of the tail cone, giving a slight right hand spin to the bomb as it falls. The tail fits over twelve 7/16 in. studs fitted into the bomb body and is securely fastened to the studs by Simmonds nuts. Three hand-holes in the tail cone give ready access to the three tail pistols.

SUSPENSION:

The bomb is suspended in the plane by twin suspension slings.

FILLING:

The bomb body contains an explosive filling of Torpex with a 1 in. layer of TNT topping added to the after end. Four inches of woodmeal/wax composition is then added, and the filling sealed with a 1/2 in. plyboard washer. The three exploders pass through holes in this washer and are held in place by a heavy base plate, which is secured by bolts to the bomb body.

REMARKS:

This bomb is designed for limited operational use, and its employment will be res-tricted to specially adapted very heavy bombers. Although designated a G.P. bomb, the T10 is essentially a deep pentration bomb (though not armor or concrete pierc-ing) depending for its effect upon the production of heavy shock waves a result of the explosion of its main charge deep within the earth.

The T10 is the American designation for the British 12,000 lb. D.P. (Dual Pene-tration) "Tallboy" bomb. Except for size, it is similar to the T14, 22,000 lb. G.P. bomb.
