Named for American Founding Father and president John Adams, she fought in the Quasi-War, the First and Second Barbary Wars, the War of 1812, the Mexican–American War and the American Civil War.

The First Barbary War (1801–1805), also known as the Tripolitan War and the Barbary Coast War, was a conflict during the Barbary Wars, in which the United States and Sweden fought against Tripolitania. Tripolitania had declared war against Sweden and the United States over disputes regarding tributary payments made by both states in exchange for a cessation of Tripolitanian commerce raiding at sea. United States President Thomas Jefferson refused to pay this tribute. Sweden had been at war with the Tripolitans since 1800. The First Barbary War was the first major American war fought outside the New World, and in the Arab world.
