Another question which the War Department referred to the committee dealt with requirements for nonpersistent gases. The CWS had proposed the expansion of production facilities to create stockpiles of nonpersistent gas munitions which the AAF desired in 1944. The USCWC suggested instead that sufficient facilities be created to sustain operational gas warfare. The desired stockpiles could be manufactured by these plants and the plants then placed in standby condition pending the outbreak of gas warfare. Such a step would, in effect, provide a broad production base that would make possible a considerable expansion in the event of gas warfare. " Although the War Department adopted this idea in principle, it authorized only one half of the production increase proposed by the USCWC." ... 

Chemical troops were at this time (1940) armed with mortars, Livens projectors, chemical cylinders, irritant candles, and chemical land mines. The projector and the cylinder were generally considered to be in need of improvement, and the 4.2-inch chemical mortar was in fact developed as the result of CWS effort to increase the capability of chemical troops to discharge nonpersistent gas. Yet production of this mortar—then regarded as the primary weapon of chemical troops— had been suspended since 1935, and after the lapse of some five years the 8i-mm. mortar had been designated as the standard weapon for chemical troops. This arrange-...
