what was the name of the titanics sister ship
HMHS Britannic HMHS Britannic (/brɪˈtænɪk/) was the final vessel built of the White Star Line's Olympic class of steamships, she was the fleet mate of both the RMS Olympic and the RMS Titanic and was intended to eventually enter service as the transatlantic passenger liner.
RMS Titanic On returning to Belfast at about 7 p.m., the surveyor signed an "Agreement and Account of Voyages and Crew", valid for 12 months, which declared the ship seaworthy. An hour later, Titanic departed Belfast to head to Southampton, a voyage of about 570 nautical miles (660 mi; 1,060 km). After a journey lasting about 28 hours and arrived about midnight on 4 April and was towed to the port's Berth 44, ready for the arrival of her passengers and the remainder of her crew.[91]
RMS Titanic Titanic was equipped with three main engines—two reciprocating four-cylinder, triple-expansion steam engines and one centrally placed low-pressure Parsons turbine—each driving a propeller. The two reciprocating engines had a combined output of 30,000 hp and a further 16,000 hp was contributed by the turbine.[19] The White Star Line had used the same combination of engines on an earlier liner, the SS Laurentic, where it had been a great success.[30] It provided a good combination of performance and speed; reciprocating engines by themselves were not powerful enough to propel an Olympic-class liner at the desired speeds, while turbines were sufficiently powerful but caused uncomfortable vibrations, a problem that affected the all-turbine Cunard liners Lusitania and Mauretania.[31] By combining reciprocating engines with a turbine, fuel usage could be reduced and motive power increased, while using the same amount of steam.[32]
Sinking of the RMS Titanic The number of casualties of the sinking is unclear, due to a number of factors, including confusion over the passenger list, which included some names of people who cancelled their trip at the last minute, and the fact that several passengers travelled under aliases for various reasons and were double-counted on the casualty lists.[228] The death toll has been put at between 1,490 and 1,635 people.[229] The figures below are from the British Board of Trade report on the disaster.[230]
