From 1937 onward all industrial mobilization planning was based on the manpower requirements of the Protective Mobilization Plan (PMP). The PMP called for an army of 400,000, within 30 days after mobilization, known as the Initial Protective Force and made up of the Regular Army and the National Guard. Within 4 months, the number would be raised to 1,000,000 men and within 14 months to a peak wartime figure of 4,000,000. The CWS planned for both units and facilities under the PMP and estimated the time it would require to furnish the mobilized forces with critical and essential items, such as gas masks, toxic agents, smoke, munitions, impregnite, airplane spray tanks, and shells for 4.2-inch chemical mortars. ... 

Although educational order contracts were awarded mostly for gas masks and components, one contract was written in fiscal 1S>40 for a CC-2 plant. In the following fiscal year the CWS awarded educational order contracts for the construction of a shoe impregnite plant and for the manufacture of filter paper. (Tables 4 and. 5) ... 

The preparation of plans for securing manufacturing plants in industry, which G-4 listed as one of the chief objectives of the CWS under the Munitions Program, was accomplished in 1940 and 1941. Under the Second Supplemental to the 1941 Appropriations Act, approved on 9 September 1940, funds were allotted to the CWS to erect plants for private industry in order to expedite production. The procedure was for the government to build the plants which would be operated under contract with private industry. Both the Ordnance Department and the Chemical Warfare Service followed the practice extensively. The CWS built charcoal and whetlerite plants and plants for the manufacture of impregnite (CC-2) under this program. ...
