Chemical Warfare Service incendiaries, development responsibility

The Chemical Warfare Service was responsible for flame throwers and incendiary bombs, and NDRC Division 11 led in the development of these weapons. 

In the process of CWS expansion gray areas of mission responsibility were clearly defined, much of this work done under the direction of Maj. Gen. William N. Porter who became Chief, Chemical Warfare Service, in May 1941. This effort to define responsibilities resulted in expanded duties for the CWS, for example, development of a high explosive shell for the 4.2-inch mortar and the acquisition of complete responsibility for the incendiary bomb program. In 1941 the War Department gave the CWS the mission of biological warfare research. 

Nor was the distinction between plan and reality confined to the training activities of the Chemical Warfare Service. After responsibility for the development, procurement, and storage of incendiary bombs was transferred from the Ordnance Department in the fall of 1941, the CWS undertook a program for which no peacetime plans had been drawn, a program that developed into one of the most important wartime efforts. The assignment of the biological warfare mission to the CWS shortly before the outbreak of war led to large-scale research and development in this new field of endeavor. 

In addition to toxic, incendiary, and smoke ammunition and bombs, as well as chemical warfare offensive weapons and equipment, the CWS was responsible for the procurement of a variety of service equipment. The latter included a truck mounted with a swinging boom crane, a chemical service truck, a chemical service trailer, a unit for mixing toxic and incendiary agents in the field, and a set for maintaining and repairing chemical warfare equipment in the field. Several of these items presented unusual problems of development and procurement. Table 8)...
