"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. After rolling off assembly line at St. Louis Army Ammunition Plant, the 105-millimeter projectiles are inspected for flaws. The shell, which starts as an 8 5/8-inch long, 38-pound piece of steel, is the workhorse of the fighting in Vietnam."
