In June 1945, the 43rd Chemical Lab. Co. had developed a stabilized flamethrower fuel (napalm). They oversaw CB construction of an Activating Plant that produced over 250,000 gallons. The 713th went through 200,000 gallons on Okinawa. Also in June, the Army cancelled all further production orders for any more M4 Sherman's. This caused Under Secretary of War Robert Patterson to place an expedite on Col. Unmacht's production of flame tanks. They were given a "Triple A" procurement priority, the same given to the B-29 and the Atomic bomb projects.
