The RMS Titanic, a British Olympic-class ocean liner, became famous as the largest ocean liner built in her day and also for sinking on her maiden voyage in 1912 with a huge loss of life. The second of a trio of superliners, the Titanic and her sisters were designed to provide a three-ship weekly express service and to dominate the transatlantic travel business for the White Star Line. The Titanic, and her sister ship the Olympic were introduced to the world in a New York Times article on April 23, 1908, almost four years before the sinking.
Built at the Harland and Wolff shipyard in Belfast, Ireland, the Titanic was the largest passenger steamship in the world at the time of her sinking. During the Titanic's maiden voyage (from Southampton, England to Cherbourg, France, then on to Queenstown (Cobh), Ireland and finally New York City), she struck an iceberg at 23:40 (ship's time) on Sunday April 14, 1912, sinking two hours and forty minutes later at 02:20 on Monday April 15, having broken into two pieces at the aft expansion joint.
The White Star line designed Titanic to compete with rival company Cunard Line's Lusitania and Mauretania, luxurious ships and the fastest liners on the Atlantic. Titanic and her Olympic -class sisters, Olympic and the then upcoming Gigantic, were intended to be the largest, most luxurious ships ever to operate (the planned name Gigantic was changed to Britannic after the disaster). Titanic was designed by Harland and Wolff chairman William Pirrie, head of Harland and Wolff's design department Thomas Andrews, and general manager Alexander Carlisle, with the plans regularly sent to the White Star Line's managing director J. Bruce Ismay for suggestions and approval. Construction of the Titanic, funded by the American J.P. Morgan and his International Mercantile Marine Co., began on March 31, 1909. Titanic No. 401 was launched two years and two months later on May 31, 1911. Titanic's outfitting was completed on March 31 the following year.
Titanic was 882 feet 9 inches (269 m) long and 92 feet 6 inches (28 m) at the beam. She had a Gross Register Tonnage of 46,328 tons, and a height from the water line to the boat deck of 60 feet (18 m). Her three propellers were driven by two four-cylinder, triple-expansion, inverted reciprocating steam engines and one low-pressure Parsons turbine. Steam was provided by 25 double-ended and 4 single-ended Scotch-type boilers fired by 159 coal burning furnaces that made possible a top speed of 23 knots (43 km/h). Only three of the four 63 foot (19 m) tall funnels were functional; the fourth, which served only as a vent, was added to make the ship look more impressive. Titanic could carry a total of 3,547 passengers and crew and, because she carried mail, her name was given the prefix RMS (Royal Mail Steamer) as well as SS (Steam Ship).
Contemporaries considered the Titanic the pinnacle of naval architecture and technological achievement, and she was thought by The Shipbuilder magazine to be "practically unsinkable." Titanic had a double-bottom hull, containing 44 tanks for boiler water and ballast to keep the ship safely balanced at sea (later ships also had a double-walled hull). Titanic exceeded the lifeboat standard, with 20 lifeboats (though not enough for all passengers). Titanic was divided into 15 compartments. Dividing doors were held up in the open position by electro-magnetic latches that could be closed by a switch on the ship's bridge and by a float system installed on the door itself.
In her time, Titanic surpassed all rivals in luxury and opulence. She offered an onboard swimming pool, a gymnasium, a Turkish bath, libraries for each passenger class, and a squash court. First-class common rooms were adorned with elaborate wood panelling, expensive furniture and other decorations. In addition, the Café Parisien offered superb cuisine for the first-class passengers, with a sunlit veranda fitted with trellis decorations.
The ship incorporated technologically advanced features for the period. She had an extensive electrical subsystem with steam-powered generators and ship-wide electrical wiring feeding electric lights. She also boasted two wireless Marconi sets, including a powerful 1,500-watt radio manned by operators who worked in shifts, allowing constant contact and the transmission of many passenger messages.
