RMS Lusitania

  RMS Lusitania was an ocean liner owned by the Cunard Line and built by John Brown and Company of Clydebank, Scotland. Lusitania was designed by Cunard's naval architect, Leonard Peskett. Peskett built a large model of the proposed ship in 1902 showing a three-funnel design. A fourth funnel was implemented into the design in 1904 as it was necessary to vent the exhaust from additional boilers fitted after Parson's then-revolutionary single reduction steam turbines had been settled on as the powerplant. Before installing the turbine powerplant in the ships, Cunard installed a smaller version of the turbine in its soon to be launched Carmania, 1905, so as to obtain a performance report on the new technology's operation.
  Lusitania's keel was laid at John Brown & Clydebank as Yard no. 367 on 16 June 1904. She was launched and christened by Mary, Lady Inverclyde on 7 June 1906. Lord Inverclyde (1861-1905), who had provided the main impetus with the British government to get the two ships built, had died before this occasion. Much of the trim on Lusitania was designed and constructed by the Bromsgrove Guild.
   Starting on 27 July 1907, Lusitania underwent preliminary and formal acceptance trials. The shipbuilder's engineers and Cunard officials discovered that high speeds caused severe vibrations in the stern, and this led to the fitting of stronger internal bracing. After these modifications, the ship was finally delivered to Cunard later in the year on 26 August. At the time of her launch Lusitania (and her sister ship Mauretania) possessed the most luxurious interiors afloat. In common with all major liners of the period, Lusitania’s interiors were decorated with a mélange of historical styles.
  Lusitania and Mauretania were smaller than the White Star Line's Olympic-class vessels. Both vessels had been launched and had been in service for several years before the Olympic class ships were ready for the North Atlantic. Although significantly faster than the Olympic class would be, the speed of Cunard's vessels was not sufficient to allow the line to run a weekly transatlantic service from each side of the Atlantic. A third ship was needed for a weekly service, and in response to White Star's announced plan to build the three Olympic class ships, Cunard ordered a third ship: Aquitania. Like White Star Line's Olympic, Cunard's Aquitania had a slower service speed, but was a larger and more luxurious vessel. Lusitania departed Liverpool for her maiden voyage on 7 September 1907 under the command of Commodore James Watt and the ship arrived in New York City on 13 September. At the time she was the largest ocean liner in service and would continue to be until the introduction of the Mauretania in November that year. During her eight-year service, she made a total of 202 crossings on the Cunard Line's Liverpool-New York Route.
  In October 1907 Lusitania took the Blue Riband for eastbound crossing from Kaiser Wilhelm II of the North German Lloyd, ending Germany's ten-year dominance of the Atlantic. Lusitania averaged 23.99 knots (44.43 km/h) westbound and 23.61 knots (43.73 km/h) eastbound.
  With the introduction of Mauretania in November 1907, Lusitania and Mauretania continued to swap the Blue Riband. Lusitania made her fastest westbound crossing in 1909, averaging 25.85 knots (47.87 km/h). In September of that same year, she lost it permanently to Mauretania.
  When Lusitania was built, her construction and operating expenses were subsidised by the British government, with the proviso that she could be converted to an Armed Merchant Cruiser if need be. At the outbreak of the First World War, the British Admiralty considered her for requisition as an armed merchant cruiser, and she was put on the official list of AMCs. The Admiralty then cancelled their earlier decision and decided not to use her as an AMC after all; large liners such as Lusitania consumed large quantities of coal and became a serious drain on the Admiralty's fuel reserves, so express liners were therefore deemed inappropriate for the role.
  General characteristics of Lusitania, Tonnage: 31,550 gross register tons (GRT) , Displacement: 44,060 Long Tons , Length: 787 ft (239.88 m), Beam: 87 ft (26.52 m) , Draught: 33.6 ft (10.24 m), Installed power: 25 Scotch boilers. Four direct-acting Parsons steam turbines producing 76,000 hp (57 MW), Propulsion: Four triple blade propellers. (Quadruple blade propellers installed in 1909),  Speed: 25 knots (46.3 km/h / 28.8 mph) Top speed (single day's run): 26.7 knots (49.4 km/h / 30.7 mph) (March, 1914), Capacity: 552 first class, 460 second class, 1,186 third class. 2,198 total , Crew: 850.
  She was torpedoed by the SM U-20, a German U-boat on 7 May 1915 and sank in eighteen minutes, eight miles (15 km) off the Old Head of Kinsale, Ireland, killing 1,198 of the 1,959 people aboard. The sinking turned public opinion in many countries against Germany, and was instrumental in bringing the United States into World War I. The sinking of the Lusitania caused great controversy, which persists to this day. (Lusitania photo is courtesy of NorthAtlanticRun).
