Description

The 50 kilogram aircraft chemical bomb, Type 100, consisted of a nose, cylindrical body and tail assembly, all made of steel. The cast steel nose was attached to the body by three one-quarter inch grub screws, and the sheet iron tail assembly, consisting of four fins welded to the tail cone, was welded to the body.

The type 50 kilogram bomb was the only persistent agent bomb produced by the Japanese in any appreciable quantity. The filling was either mustard, a mixture of mustard and lewisite (50/50) or with additives to lower the freezing point. The “yellow” in the bomb’s name indicated that it contained a blister gas. There was no differentiation between different blister gases.

The 100 type 50 kilogram bomb was the only casing filled with non-persistent gases. The two agents which were used as fills were phosgene (CG) and hydrocyanic acid (HCN). The best information available indicates that HCN was filled only in experimental quantities. The phosgene bomb was the Type 100, 50 kilogram Blue bomb, and the HCN bomb was the Type 100, 50 kilogram Brown Bomb.
