SS Pennsylvania was an iron passenger-cargo steamship built by William Cramp & Sons in 1872. The first of a series of four Pennsylvania-class vessels and the lead ship in her class, Pennsylvania and her three sister ships—Ohio, Indiana and Illinois—were the largest iron ships ever built in the United States at the time of their construction, and amongst the first to be fitted with compound steam engines. They were also the first ships to challenge British dominance of the transatlantic trade since the American Civil War.
Launched with great fanfare in 1872, Pennsylvania narrowly escaped destruction by hurricane in her first year of operation, but went on to enjoy a long and distinguished career. Though soon outclassed by newer ships, she continued in operation for some 44 years, plying various transatlantic routes and later playing a role in the Alaskan gold rush and serving as a troopship during the Spanish–American War. The ship was finally destroyed by a fire in 1918.
