A delegation representing them lobbied against Taylorism, eventually persuading Congress to outlaw such management systems in navy yards. Yet when it was all over, the Charlestown yard was organized quite differently than in the 19th century, making it a more efficient builder and repairer of modern naval vessels and helping it to perform as it did during World War I. U.S.S. _Bridge_, commissioned as the first American troops were enroute to France, exemplified the yard’s progress since the dark 1880s. Following a long campaign by a job-desperate Boston to have the ship built at Charlestown, _Bridge_ was laid down in 1914 and launched two years later. It was the Navy’s first refrigerated supply ship, with a steel hull and a boiler that could burn oil or coal. Its 423-foot length made _Bridge_ the largest vessel yet built at Charlestown and its first major ship since the 1870s. After demonstrating its competence with _Bridge_, Charlestown was assigned _Brazos_, two other fuel ships, and a destroyer tender. The war-spurred building program helped Charlestown stay busy when peace came, as the last three vessels weren’t laid down until after the armistice. In fact the number of employees actually rose, to almost 13,000 in 1919. Besides the shipbuilding, there was work converting ships to troop transports to bring the soldiers home and stripping military gear from ships returning to civilian service. Charlestown repaired a large number of destroyers, subs, and battleships small enough for Dry Dock 2. To increase its docking capacity, the yard purchased in 1920 a new state-built dry dock in South Boston. At the time it was the country’s largest dry dock, becoming the nucleus of the yard’s South Boston Annex. Events conspired in the 1920s to dampen the yard’s postwar prosperity. The 1922 Five-Power Treaty limited new ship construction and the overall number of vessels, meaning less repair and outfitting work for naval shipyards. In any case the political mood was to spend money on other things. After the destroyer tender _Whitney_ was launched in 1923, there was no more construction at Charlestown, other than a couple of tugs, for the rest of the decade. And as the Japanese grew increasingly expansionist, much of the fleet was moved to the West Coast, further reducing work at the yard.
