US Bomb, 30 lb Chemical, M1
The 30 pound M1 chemical bomb was developed to meet the requirement for a bomb case strong enough to withstand "safe dropping" on normal soil from a height of 7,000 feet. It was intended to produce such an irritating physiological effect upon enemy personnel so as to make them ineffective.
The M1 bomb was made by swaging a length of seamless steel tubing to a streamlined shape, fully closed at the tail end. A full length burster well was assembled to the nose end of the body by means of pipe threads that sealed the bomb against leakage of the filler. A full length burster of tetryl was used.
Nothing else to see.
