The Bureau of Ships was initially organized in five divisions by 15 August 1940: Design, War Plans, Shipbuilding, Maintenance, and Administration. At the start it was tasked with implementing the massive Fiscal Year 1940 (FY40) naval procurement plan, which included 11 aircraft carriers, nine battleships, six large cruisers, 57 other cruisers, 95 destroyers, 73 submarines, and dozens of auxiliary vessels (most of the battleships and large cruisers were never completed). By late 1942 a reorganization subordinated Design as a branch of Shipbuilding, a Radio division (which included sonar) was created from the former Radio branch of the Design division, and Finance became a division. By mid-1945 the Radio division had become the Electronics division, and Shore and Contracts divisions had been added. The entry of the US into World War II on 7 December 1941 resulted in the FY42 procurement plan and its component war emergency programs, which dwarfed FY40 by projecting 20 aircraft carriers, 50 escort carriers, 35 cruisers, 144 destroyers, 750 destroyer escorts, 127 submarines, and many other ships. The escort carriers and destroyer escorts were ship types that had not been built before, and that many of the projected ships were cancelled in 1944-45. From its inception in 1940 BuShips supervised the building of a larger navy than any previous one in the space of five years. A media release on 22 May 1945 stated that 8 million tons of new ships costing 17 billion dollars (in 1945 money) had been built during the war, and a further 5 million tons of existing ships had been acquired or converted. On 7 December 1941 the total tonnage of the fleet was 2,680,000 tons. In numbers of ships, 7,695 vessels were on hand in December 1941, including landing craft. Over 100,000 vessels and landing craft were built during the war, including 1,150 combatants, 557 auxiliary ships, and 82,266 landing craft.
