George Washington's concern over standardization of rifles for the Continental Army led to the formation of national armory and to his selection of Springfield as its site. Completed in 1794, it was the first national armory in the United States. Like the Robbins and Lawrence Armory, the Springfield Armory was an outstanding machining center for the design and mass production, employing notable engineers such as Thomas Blanchard (1788-1864), Thomas Warner, and Cyrus Buckland.

In 1794, the Delaware legislature authorized a lottery to fund the erection of ice piers in the harbor at New Castle. The ice harbor was designed to protect anchored ships from storms and ice. At the time, New Castle served as the principal winter port for ships from the Port of Philadelphia because ice on the Delaware River posed such a serious hazard to the wooden-hulled vessels. The harbor was the first of its type on the river and the last one to be maintained as the need for them declined. It served as a model for the other four harbors constructed in the area.
