The Armory was better prepared for war production in 1941 than it had been in 1917. At the time of the Japanese attack on Pearl Harbor, the production quota of M1's was 1,100 per day; by July 1943 it nearly doubled to 2,100 per day. At the same time the workforce increased from 7,500 to 12-13,000. As in World War I, women were hired to help overcome the labor shortage induced by the draft; they constituted 20% of the workers by June 1942 and 43% by June 1943. Despite this measure, the workforce declined in number to 11,300-11,800 in the second half of 1943, to 10,900 by June 1944, and to 9,400 by the end of 1944.

"She's a WOW (Woman Ordnance Worker)" with Rosie the Riveter

During World War II some three million women worked in war plants across the United States. Working women were vital to the war effort, as the loss of men to military service left a workforce shortage in many areas. The U.S. Government undertook a major public relations campaign to encourage women to work. The use of an invented character- "Rosie the Riveter" - on a brightly colored poster was a powerful propaganda piece.

While some leaders only urged women to continue such traditional roles as knitting, buying bonds, stretching rationed foodstuffs, and keeping up the nation's morale, others on the home front challenged women to join the ever-growing ranks of America's "production soldiers." In September 1942, Secretary of War Henry L. Stimson made public his plan to double the number of women hired in war jobs. Newspaper accounts of that time reported that since 1 June 1942 the number of skilled women workers in the War Department had risen from 3 percent to 10 percent. Almost 35 percent of the department's unskilled workers were women. Uncertainty about the willingness and ability of American housewives to assume a larger defense role was expressed nationally as well as locally. One labor analyst warned that, "The employment of millions of untrained workers, including old men, youths, and housewives,...[would] inevitably result in a material and gradual dilution of labor skills, which...[meant] a decline in manpower output." The previously successful employment of women defense workers, according to this same analyst, was "...attributable to the fact that the more experienced and best adapted have naturally been the first employed. As...[the nation drew] more and more upon inexperienced and untrained homemakers, the average efficiency of women...[would] decline."

Most of the women employed by the Army had to adjust not only to working outside the home but had to accustom themselves to working under conditions that would have tried the stamina and patience of experienced male industrial workers. In addition, many of the women workers at both arsenals contributed what little spare time they had to supporting a variety of home front activities such as Red Cross work, war bond drives, and packaging special seasonal boxes for distribution to soldiers overseas.

The pressures of work, the strain of trying to keep up with family obligations, the stress of worrying about loved ones fighting in the war or being held prisoner behind enemy lines, the lack of adequate rest and nutrition, even ill health all contributed to higher levels of absenteeism among women workers. To keep up the morale of all their workers, Army officials sponsored special after-hours social events such as dances. Another was the September 29th, 1943, big band concert by Benny Goodman and his “Spotlight Band” given to the employees on the grounds near the Main Arsenal (housing the present-day Museum of Springfield Armory National Historic Site). Special awards ceremonies were held so that employees could be a part of the recognition given to the production successes enjoyed by all workers.
