How did NJ help the war effort of the US world War1?

Answer 1

During World War I, New Jersey was the home to much shipbuilding activity, as well as refineries and important ammunition factories. Some existing factories, such as the Singer sewing machine company, converted to make weapon parts. After discovering some German chemical secrets, New Jersey became one of the largest chemical producers in the world; some of the companies are still there today.

Camp Merritt and Fort Dix were notable training sites; after the war, Fort Dix became a "demobilization center," where thousands of men were processed out of the military.
