Prologue The U.S. government established Charlestown Navy Yard as the newly-formed republic was meeting early challenges to its merchant shipping. In the decade after gaining independence, the young nation kept no standing navy. But continuing raids on U.S. commerce by Barbary pirates and French privateers in the 1790s spurred Congress to authorize the construction of new warships. Realizing that existing private shipyards were inadequate for the increasingly ambitious shipbuilding program, the Secretary of the Navy established in 1800-1801 six federal yards to build, outfit, repair, and supply naval vessels. These facilities at Portsmouth, N.H.; Boston; New York; Philadelphia; Washington, D.C.; and Norfolk, Va., were the nucleus of the naval shipyard system. Except during the Civil War, they launched most of the Navy’s vessels until the advent of steel hulls in the 1880s, when private yards began building them in greater numbers.
