During World War II, the United States faced the monumental task of building a vast fleet of merchant ships to support its military operations and sustain the war effort. The U.S. Maritime Commission contracted numerous private-sector shipyards to construct self-propelled merchant ships. These shipyards produced various vessels, including Liberty ships, Victory ships, and T2 tankers, significantly enhancing the nation’s shipping capabilities. This article explores the contributions of these shipyards and highlights their impressive production records.
Overview of Shipbuilding Efforts
Private-sector shipyards were instrumental in constructing the necessary vessels to support military and commercial needs. The primary products of these shipyards included:
