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 T14 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. 82 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 T14 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 general arrangement of this bomb is identical to that of the 12,000 lb. T10 illustrated on page 60. The two bombs are identical in all respects, the T14 being merely an enlar-ged version of the T10.

The T14 is American designation for the British 22,000 lb. D.P. "Grand Slam" bomb.
