USS Constitution is launched

Why the United States needed a navy

After independence, American merchant ships traded across the Atlantic, but the young republic had few means of protecting them. North African corsairs seized vessels and crews, while European wars disrupted neutral commerce. In 1794 Congress authorized six new frigates as the nucleus of a permanent naval force.

Naval architect Joshua Humphreys designed large, fast, heavily armed frigates able to defeat ordinary frigates yet avoid stronger ships of the line. Constitution was built at Edmund Hartt’s shipyard in Boston under the supervision of George Claghorn. Its sturdy wooden construction would later help give the ship its famous nickname.

The launch on 21 October 1797

On 21 October 1797, Constitution entered the water at Boston. The launch marked a milestone in the American effort to establish an independent navy, but a newly launched hull was not yet a combat-ready warship. The crew still needed equipment, provisions, training and preparations for service at sea.

The frigate began its first cruise in July 1798, during growing tensions with France. It subsequently took part in conflicts in the Mediterranean and Atlantic. The October launch date therefore represents the birth of a vessel whose most celebrated battles still lay many years in the future.

How the ship became “Old Ironsides”

During the War of 1812, Constitution fought the British frigate HMS Guerriere. Some British shots reportedly failed to pierce its thick oak sides. The ship gained the nickname “Old Ironsides,” even though its hull was made of wood, not iron. Its victories helped raise American naval morale and became powerful national symbols.

The frigate survived the age of sail, later serving as a training vessel and historic landmark. Today it is preserved in Boston and remains a commissioned U.S. Navy warship. The vessel launched in 1797 thus connects the early republic with an unusually tangible piece of naval history.

Why the ship still matters

The Constitution is much more than a monument to one naval battle. Its history spans the early republic, naval warfare, long-distance trade and changing ideas about national memory. Preserving a working wooden warship requires painstaking repairs and specialised skills. When visitors see it in Boston, they encounter a material link to the maritime world of the eighteenth and nineteenth centuries.
