"The Chevrolet division of General Motors under contract with the government is once more producing 105-millimeter artillery projectiles as they did during World War II... Early in 1966 plans were formulated to reactivate the plant. The 105-millimeter shell had become a principal ammunition of the fighting in Vietnam. In August of 1966 the federal government and General Motors agreed on a $22 million contract to produce 4,500,000 rounds of the 105-millimeter shells. Target date for production was Jan. 1, 1967, but Chevrolet is already operating the plant at about 18 percent capacity. In machinery building: Hole is put in front of shell; the cavity is cleaned and the nose bored and faced. Next the threads are put in the nose, the base is leveled, and a band groove is made."
