Navy ordered . Finally, the Texas Oil Company and the Edward F. Luckenbach Company ordered four tankers and freighters, respectively. World War I War brought opportunities for expansion for the yard. This meant the building of a steel mill and a sheet metal shop that contained one of the best molds in the country. The steel mill was capable of prefabricating of steel a day. A building slip was also constructed, costing $ (equivalent to $ in today's dollars). The yard created a department that was dedicated to the welfare of its workers during this time, as well. 1916 brought nineteen contracts to the yard, eight of which were for the O-class submarine, and ten more submarines were laid down for the Royal Navy, with another ten being built in Montreal at the Canadian Vickers yard. The submarines, once built, were stored at the nearby Boston Navy Yard until the country entered the war. Over 15,000 persons were working at the yard at the time, including Joseph P. Kennedy. Entry of the United States into the war brought twenty-eight destroyer orders to the yard. Due to this sudden increase in production, the yard needed to expand. Soon, a suitable location was found on nearby Squantum Point, and the Victory Destroyer Plant started construction in 1917. Located on of land, the yard exclusively built destroyers, with being the last ship constructed at the plant. In 1920, the yard was turned over to the United States government and dismantled. This same year, Bethlehem Steel split off its shipbuilding division into the Bethlehem Shipbuilding Corporation, which was headquartered at the yard. Combined with the Squantum yard, Fore River turned out 71 destroyers during the war, more than any other American yard. Besides the other Quincy yard, Bethlehem built the Fields Point Plant for boiler construction in nearby Providence, Rhode Island and the Black Rock Plant for turbines in Buffalo, New York. The yard constructed in 174 days. Not to be outdone, the Squantum yard built in twenty-eight days, delivering it to the Navy seventeen days later. Such was the speed at which the yard produced ships that the Navy was forced to moor the ships at the Boston Navy Yard for lack of crews. The yard's speed allowed for the management to enter a bet with another Bethlehem plant, Union Iron Works, to see which plant would deliver more ships in a year.
