SS Polonia (1910) was a passenger and cargo steamship built by William Cramp & Sons in Philadelphia for the Polish American Navigation Company. Launched in 1910, the ship primarily served the transatlantic route between New York and ports in Europe, including Gdynia, Poland. During World War I, Polonia was seized by the United States government and operated as a troop transport. After the war, the ship resumed commercial service until 1939 when it was requisitioned by the Polish government for military use. Following the German invasion of Poland in 1939, Polonia escaped to England and was taken over by the British government for war duties. The ship was involved in various convoys and rescue missions during World War II. In 1945, Polonia was handed back to the Polish government and returned to commercial service until 1951 when it was scrapped in Italy. Throughout its operational life, SS Polonia played a significant role in both civilian and military transportation, contributing to transatlantic travel and wartime efforts.
