SS Great Eastern was an iron sail-powered, paddle wheel and screw-propelled steamship designed by Isambard Kingdom Brunel, and built by John Scott Russell & Co. at Millwall Iron Works on the River Thames, London, England. She was the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of was surpassed only in 1899 by the 17,274-gross-ton , her gross tonnage of 18,915 was only surpassed in 1901 by the 20,904-gross-ton and her 4,000-passenger capacity was surpassed in 1913 by the 4,234-passenger . The ship having five funnels (which were later reduced to four) was unusual for the time. The vessel also had the largest set of paddle wheels. Brunel knew her affectionately as the "Great Babe". He died in 1859 shortly after her maiden voyage, during which she was damaged by an explosion. After repairs, she plied for several years as a passenger liner between Britain and North America before being converted to a cable-laying ship and laying the first lasting transatlantic telegraph cable in 1866. Finishing her life as a floating music hall and advertising hoarding (for the department store Lewis's) in Liverpool, she was broken up on Merseyside in 1889. After his success in pioneering steam travel to North America with and , Brunel turned his attention to a vessel capable of making longer voyages as far as Australia. With a planned capacity of 15,000 tons of coal, Great Eastern was envisioned as being able to sail halfway around the world without taking on coal, while also carrying so much cargo and passengers that papers described her as a "floating city" and "the Crystal Palace of the sea". Brunel saw the ship as being able to effectively monopolize trade with Asia and Australia, making regular trips between Britain and either Trincomalee or Australia. On 25 March 1852, Brunel made a sketch of a steamship in his diary and wrote beneath it: "Say 600 ft x 65 ft x 30 ft" (180 m x 20 m x 9.1 m).
