Commercial introduction of the Whitehead self‐propelled torpedo in 1875 triggered rapid development of coastal and seagoing torpedo boats in Europe. “Jeune Ecole” enthusiasts in France hailed growing squadrons of torpilleurs as effective counters to British naval superiority; yet by 1890, Britain, Germany, and Japan had acquired comparable flotillas. The U.S. Navy, amid post–Civil War doldrums, engaged yacht designer Nathaniel Herreshoff to construct swift torpedo craft, including the spar torpedo boat Lightning (1876); the Stilletto (1887), armed with John Howell's automotive torpedo; and finally the USS Cushing (1890), the navy's first steel‐hulled torpedo boat.
Britain's introduction in 1893 of the torpedo boat destroyer, direct antecedent of the more seaworthy destroyer, dimmed prospects for the torpedo boat, whose influence on fleet operations during the Spanish‐American War proved less impressive than at Tsushima in the Russo‐Japanese War. During World War I, German torpedo boats, torpedo‐armed destroyers, U‐boats, and naval mines combined to inhibit British Grand Fleet operations severely, but postwar naval designers showed little interest in the prevailing torpedo boat configuration. Torpedo attacks by surfaced U‐boats accounted significantly for Allied merchant ship losses. Torpedo boats also reappeared during World War II in a smaller configuration, as wooden‐hulled motor torpedo boats, swift launches active notably in the English Channel, Mediterranean, and (against Japanese supply barges) the Southwest Pacific. In postwar years, these short‐lived craft were rapidly replaced by missile launches, terminating a century of torpedo boat development.

torpedo boat, small fast warship built specially for using the torpedo as a means of attack. The first modern torpedo boat was the Lightning, built for the British navy in 1877 by the shipyards of Sir John Isaac Thornycroft. Torpedo boats were adopted by most of the world's major navies, but as they increased in size the destroyer was developed as an effective defense against them. They diminished in importance after the Russo-Japanese War (1904–5) and were used sparingly in World War I, but they were widely employed in World War II. At that time torpedo boats, often referred to as PT boats, were commonly used in attacking enemy coastal shipping and light naval forces under cover of darkness and bad weather. They were usually wooden vessels 75 to 125 ft (22.8–38.1 m) long, powered by gasoline or diesel engines and capable of very high speeds.
