Were there any factories creating war supplies in Colorado during World War 2?

Most Likely. Throughout World War II many American factories changed from making whatever to making armaments for the war. There was a huge increase in factories making armaments because of having to supply U.S. troops as well as others such as the U.K. and other allied nations. The allies in Europe were poor and right in the battle feild so the U.S. gave money weapons and men. I would say there was definatly a factory in every state makeing weapons at leats one in each anyway.
