The Electrical Era
 
The ELECTRICAL ERA is introduced with this display.

Springfield Armory NHS, US NPS

The Twentieth Century brought more that the change from steam to electrical power. New techniques of metallurgy, of preserving metals, and of applying machine power to manufacturing were pioneered at the Armory. With the introduction of the M1, which could not be manufactured on the Armory’s ancient machinery, modern and more efficient equipment was designed and installed.

The two world wars caused dramatic, if temporary, changes in the work force as women replaced men in many jobs. After the Second World War research and development replaced manufacturing as the Armory’s preeminent function.

MAKING THE PEEP SIGHT            The M1 was a totally machine-made weapon. These photographs document the numerous steps required just to make one small component, the rear peep sight. Note that it begins as part of a steel ring cut from a long tube.

steps in the manufacture of the peep sight

Even a relatively simple part of the M1, like the rear peep sight, required many steps to complete. The Army produced many display boards like this to demonstrate the M1 manufacturing processes.

WOWs

CASE 66
WOW Kerchief
During World War II, when great numbers of men were in military service, their places on Armory production lines were taken by WOWs – Women Ordnance Workers. At one point some 45% of the Armory work force was made up of women. Kerchiefs like this helped boost morale among these women and also served a safety function by keeping long hair from being caught in machines.

WOWs                The demand for skilled labor, regardless of religious or ethnic background, had long been a characteristic of Springfield Armory and had influenced the community which grew up around the facility. The two World Wars of the Twentieth Century created additional demands for labor, demands that could only be met by hiring women. During World War II Women Ordnance Workers, with their distinctive bandannas, contributed to the high productivity of the Armory.

CASE 67

In Two World Wars

In the midst of the technology of machines and weapons it is easy to lose sight of the fact that the workers were the Armory’s most valued resource. Persons with a wide variety of skills and aptitudes were required, not only to build the weapons, but to provide support functions to the Armory’s operations. These posters, badges, and other memorabilia from the period of the two World Wars help remind us of the human side of the Armory’s history.

CASE 68

At the beginning of the Twentieth Century the weapons produced at Springfield Armory still required some hand finishing to complete production. By the time the United States entered World War II the weapons were almost completely machine made, and many of the machines had been designed at the Armory. By the time of the Vietnam War, however, the precision-made M14 could not compete economically with the commercially-produced M16.

Did You Know?
Freedom is not standing still. A symbolic feature that people cannot see is the broken chain wrapped around the Statue's feet. Protruding from the bottom of her robe, the broken chains symbolize her free forward movement, enlightening the world with her torch free from oppression and servitude.
