of 1942, the Maritime Service was transferred to the newly created War Shipping Administration which itself was created for the purpose of overseeing the operation of the fleet of merchant ships being built by the Emergency Program for the needs of the U.S. Armed Services. The WSA was added to the list of wartime agencies created within the Roosevelt Administration and was intended to relieve the already full plate of responsibilities of the Commission, yet they shared the same Chairman in Admiral Land and so worked very closely together. Post World War II With the end of World War II, both the Emergency and Long Range shipbuilding programs were terminated as there were far too many merchant vessels now for the Nation's peacetime needs. In 1946, the Commission was chaired by Vice admiral William W. Smith and the Merchant Ship Sales Act was passed to sell off a large portion of the ships previously built during the war to commercial buyers, both domestic and foreign. This facilitated the rebuilding of the fleets of both allied nations such as Great Britain, Norway and Greece which had lost a majority of their prewar vessels to the Battles of the Atlantic and Mediterranean Sea. Although not sold outright to nations that were enemies during the war, U.S. merchant ships helped nations such as Japan, which had lost many hundreds of its merchant vessels to the Allies' submarine offensive in the western Pacific, recover their merchant shipping capacity via the loan of vessels and the carrying of relief cargoes to war ravaged Europe. Ships were also used in both the rebuilding programs under the Marshall Plan and the transport of food aid sent during the desperate winter of 1945-46 when famine loomed large over much of the European continent. For the next 25 years, in ports all around the world one could find dozens of ships which had been built during the war but which now were used in peace. Many of those same ships continued to sail until the early 1980s but most had been sold for scrap in the 1960s and 1970s as more modern designs were developed and more efficient slow speed diesel engines introduced to replace the steamships which predominated those built by the Commission during the war years. Ships not disposed of through the Ship Sales Act were placed into one of eight National Defense Reserve Fleet(NDRF) sites maintained
