The SS Pittsburgh, later known as SS Pennland, was a sizable transatlantic ocean liner constructed by Harland & Wolff in Belfast. Laid down in November 1913, her construction was interrupted by the outbreak of World War I in August 1914, delaying her launch until 11 November 1920. She measured approximately 575.3 feet (175.4 meters) in length, with a beam of 67.8 feet (20.7 meters) and a depth of 41.2 feet (12.6 meters). Her tonnage was 16,322 GRT and 9,856 NRT, and she featured three screws driven by a combination of triple-expansion steam engines and a low-pressure steam turbine, enabling her to reach speeds of around 16 knots. As built, Pittsburgh was equipped with significant electrical systems and had berths for 2,100 passengers, split between 600 cabin class and 1,500 third class, making her one of the early ships to offer cabin accommodations. Her cargo holds included 19,920 cubic feet of refrigerated space, suitable for perishable goods. She was launched with two funnels and two masts, highlighting her typical early 20th-century design. Initially operated by White Star Line, she commenced her maiden voyage from Liverpool to Boston and Philadelphia in June 1922. Throughout her service, she experienced notable events, including rescuing Italian sailors from the steamship Monte Grappa in November 1922 and surviving a severe wave in March 1923 that damaged her bridge and navigational equipment, yet she safely reached Bremen. Renamed Pennland in 1926 to align with Red Star Line's naming conventions, she underwent several ownership and route changes, including a refit in 1935 to serve as a one-class ship with up to 550 passengers. During World War II, Pennland was converted into a troopship under the Ministry of War Transport. Her wartime service included convoy passages across the Atlantic and Mediterranean, supporting Allied operations. In April 1941, she was involved in a notable attack off Greece, where German dive-bombers damaged her severely, and she was ultimately sunk by gunfire from HMS Griffin after an attack in the Saronic Gulf. Her sinking marked the end of her varied and significant maritime career, and she now rests as a shipwreck in the Saronic Gulf.
