Some of the merchant ships were subsequently converted to other purposes, including as troop transports and a Royal Navy aircraft carrier.
President Franklin D. Roosevelt launched the first liberty ship, SS Patrick Henry, at the yards of Bethlehem Steel, Baltimore, Maryland, giving a speech as he did so.
We must build more cargo ships and still more cargo ships - and we must speed the program until we achieve a launching each day, then two ships a day, fulfilling the building program undertaken by the Maritime Commission.Our shipbuilding program - not only that of the Maritime Commission, but of the Navy - is one of our answers to the aggressors who would strike at our liberty.I am speaking today not only to the shipworkers in the building yards on our Coasts, on our Great Lakes and on our Rivers - not only to the thousands who are present at today's launchings - but also to the men and women throughout the country who live far from salt water or shipbuilding.I emphasize to all of you the simple, historic fact that throughout the period of our American life, going way back into Colonial days, commerce on the high seas and freedom of the seas has been a major reason for our prosperity and the building up of our country.To give you one simple example: It is a matter of history that a large part of the capital which in the middle of the past century went into the building of railways and spread like a network into the new undeveloped areas across the Mississippi River, across the Plains and up into the Northwest, was money which had been made by American traders whose ships had sailed the seas to the Baltic, to the Mediterranean, to Africa and South America, and to Singapore and China itself.Through all the years after the American Revolution your Government reiterated and maintained the right of American ships to voyage hither and yon without hindrance from those who sought to keep them off the seas or drive them off the seas.
As a nation we have realized that our export trade and our import trade had a definitely good effect on the life of families, not only on our Coasts but on the farms and in the cities a hundred or a thousand miles from salt water.Since 1936, when the Congress enacted the present Merchant Marine Law, we have been rehabilitating a Merchant Marine which had fallen to a low level.
They have caught the true spirit with which all this nation must be imbued if Hitler and other aggressors of his ilk are to be prevented from crushing us.We Americans as a whole cannot listen to those few Americans who preach the gospel of fear - who say in effect that they are still in favor of freedom of the seas but who would have the United States tie up our vessels in our ports.
