The RMS Baltic was a prominent ocean liner operated by the White Star Line, launched on November 21, 1903, and entering service in June 1904. She was constructed at Harland and Wolff shipyards in Belfast, initially intended to match the size of her sister ships Celtic and Cedric. However, she was subsequently enlarged by cutting the hull in two and setting back the rear section by nearly six meters, increasing her gross register tonnage by approximately 3,000 tons to 23,876 GRT, making her the world's largest ship until May 1906. Her overall length was 222.2 meters (729 feet), with a beam of 23 meters (75 feet 6 inches), and a draft of 16 meters (52 feet 6 inches). The vessel featured a black hull with a white superstructure, four masts, and four funnels painted ocher-brown with black cuffs, characteristic of White Star Line ships. Powered by two four-cylinder triple-expansion steam engines driving twin propellers, Baltic could reach speeds up to 18 knots, with an average of around 16 knots. Her machinery initially developed 14,000 horsepower, later upgraded to 16,000 horsepower. She consumed approximately 280 tons of coal daily, supplied with electricity, and equipped with modern amenities like electric lighting, refrigeration, and luxurious passenger facilities. Her passenger capacity was notable: 425 in first class, 450 in second class, and 2,000 in third class, with additional refits reducing third-class capacity over time. Baltic's service history included transatlantic crossings between Liverpool and New York. She played a significant role in maritime safety, notably rescuing passengers from the colliding ships Republic and Florida in 1909, highlighting the importance of wireless telegraphy. She also transmitted a warning about icebergs prior to Titanic's sinking in 1912 and was involved in her own near-miss with the latter, diverting to aid in the rescue operations. During World War I, Baltic was requisitioned as a troopship, carrying American troops—including General Pershing—to Europe and surviving a torpedo attack in 1917. She transported vital military personnel and supplies, including large numbers of Canadian soldiers, before resuming civilian service post-war. Her later years saw modernization, including a 1927 refit to offer cabin and tourist class accommodations. Ultimately, declining demand and economic pressures led to her retirement in 1932, and she was scrapped in Japan in 1933 after nearly three decades of service. The RMS Baltic remains a significant example of early 20th-century ocean liner design and wartime maritime history.
