Twin Cities Army Ammunition Plant team was led by my Grandfather Hans J. Wessel and and Cy Pesek. The TCAAP facility was constructed between 1941 and 1943 in Arden Hills, Minnesota. Before that time the site was primarily used as farmland. After the acquisition of the land and to meet the Army’s World War Two mission, TCAAP was developed. During a sixteen month period and at a cost of $73 million, over 300 buildings were constructed at the site. In early 1942, the manufacturing of small arms ammunition and other related materials had begun. The complex continued to grow with 83 miles of sewer, 37 miles of road and railroad track. At its peak, the plant employed approximately 26,000 people, primarily manufacturing ammunition for World War Two and subsequently the Korean and Southeast Asian conflicts. During World War Two, TAACP produced more than four billion rounds of ammunition.
