BODY CONSTRUCTION

The body consists of a welded sheet metal container welded to a ogival nose, and a stepped conical base. The base is closed with a plug, while the nose is closed with a fuze adapter. A perforated central tube contains a 230 gm. black powder charge to ignite the thermite balls. The thermite balls are formed of two (2) thin sheet metal stampings, about 2.4 inch in diameter, and weigh-ing about 10.5 oz. each.

TAIL CONSTRUCTION

The tail fins consists of a fin sleeve which fits over the base of the bomb, and is held in place by four (4) bolts. Four (4) narrows sheet metal fin blades are welded to the fin sleeve, to form a square box with riveted sup-porting struts.

REMARKSEach thermite ball is drilled through the center and contains two ignition pel-lets. When used against built-up areas, the best altitude for burst is 600 to 1200 feet so that the balls will still be burning when they land. The bomb can be dropped without fuze or black powder igniter charge, or with the fuze on safe. On impact, there is sufficient heat and shock to ignite the thermite balls, and the bomb burns as one mass. Since the bomb will ignite on impact, duds will seldom be encountered. It is believed that the letter "T", in the designation, indicates thermite and SHCH indicates sphere. There is a report of this type of bomb being found with a load of small incendiary bombs, either ZAB-2.5-1 or ZAB-2.5T, without tails or fuzes.
