Jeremiah O’Brien is the product of an emergency shipbuilding program of World War II that resulted in the construction of more than 2,700 Liberty ships. Designed as cheap, quickly-built simple cargo steamers, the Liberty ships formed the backbone of a massive sealift of troops, arms and material to every theater of the war. The ship made wartime voyages between the east coast, Canada and the United Kingdom to South America, Australia and the Philippines. From June until December 1994, O’Brien made eleven trips between the United Kingdom and Normandy in support of the D-Day invasion, including a trip from Belfast to Normandy with troops from Patton’s Fifth Division.
