1941: The SS Patrick Henry is launched, becoming the first of more than 2,700 Liberty ships to be built by the United States during World War II. Liberty ships were cargo ships designed to be cheap and quick to build, replacing riveting with welding and using oil-fired boilers. The ships earned their name when, during the launch of the Patrick Henry, President Franklin D. Roosevelt said that this new class of ships would bring liberty to Europe.
