    The Olympic-class ocean liners were a trio of ocean liners built by the Harland & Wolff shipyard for the White Star Line in the early 20th century. Although the three were the largest and most luxurious of their time, two were lost early in their careers: Titanic sank on 15 April 1912 after hitting an iceberg in the North Atlantic, and HMHS Britannic sank on 21 November 1916, after hitting a mine laid by the German minelayer, U-79, triggering one of the mines laid in a barrier off of Kea during World War I. Olympic, the eldest sister and namesake of the class, continued in service until she was laid up and scrapped in 1935, alongside Cunard's RMS Mauretania.[2]

    Although two of the three vessels did not have successful careers, they are among the most famous ocean liners ever built. Decorative elements of Olympic were purchased to adorn many places (and even a cruise ship, Celebrity Millennium). Titanic's story has been adapted into many films and books, and Britannic has also inspired a movie of the same name.[3]

    Origin and construction

    The Olympic-class had its origins in the intense competition between the United Kingdom and the Germany in the construction of the liners. The Norddeutscher Lloyd and HAPAG, the two largest German companies, were indeed involved in the race for speed and size in the late nineteenth century. The first in service for the Norddeutscher Lloyd was SS Kaiser Wilhelm der Grosse, which won the Blue Riband in 1897 [4] before being beaten by SS Deutschland of HAPAG in 1900.[5] Then followed the three sister ships of the Kaiser Wilhelm der Grosse: SS Kronprinz Wilhelm, SS Kaiser Wilhelm II and SS Kronprinzessin Cecilie. In response to this, the Cunard Line of the UK ordered two vessels whose speed earned them the nickname "greyhound of the seas": Lusitania and Mauretania.[6] Mauretania kept the Blue Riband for more than twenty years, from 1907 to 1929.[7][2]

    The White Star Line knew that their Big Four, a quartet of ships built for size and luxury but not speed[8], were no match for the Cunard's new liners. In 1907, J. Bruce Ismay, president of White Star and William J. Pirrie, director of the shipyard Harland & Wolff decided to build three vessels. And so, the Olympic-class ships were built to surpass rival Cunard's largest ships, Lusitania and Mauretania, in size and luxury. Titanic, along with her sisters, Olympic and the soon to be built Britannic (provisionally named Gigantic)[9], were intended to be the largest and most luxurious ships to operate on the North Atlantic, but not the fastest, as the White Star Line had already switched from high speed to size and luxury. The three vessels were designed by Thomas Andrews and Alexander Carlisle.[2]

    Construction of Olympic started in December 1908 and Titanic in March 1909. The two ships were built side by side.[10] The construction of Gigantic began in 1911 after the commissioning of Olympic and Titanic's launch. Following the sinking of Titanic, Gigantic was renamed Britannic, and the two remaining vessels underwent many changes in their safety provisions.[11]

    Specification

    Propulsion was achieved through three propellers: two lateral propellers had three blades, while the central propeller had four. The two lateral propellers were powered by reciprocating steam quadruple expansion, while the central one was driven by a steam turbine.[12] Everything was powered by 29 coal-fired steam boilers in six compartments. However, Olympic's boilers were adapted for operating oil at the end of the First World War,[13] which reduced significantly the number of engineers required to operate the ship from 350 to 60.[14]

    The vessels were 269 metres (883 ft) long, their tonnage surrounded 46,000 GRT[15]. Olympic, originally the smallest of the three, became the biggest British ship ever constructed after her refit in 1912, until the commissioning of RMS Queen Mary in 1936.[16] All three vessels transported four funnels, with the fourth being a dummy which was used for ventilation purposes. On the one hand it was a decoration to establish a symmetry in the ships' profile, on the other hand it prevented the large amount of ventilation cowls on deck as on Cunard's Lusitania and Mauretania.[15]

    Sixty-four lifeboats were the number possible to be added to each ships.[17] However, only 20 boats were installed on Olympic and Titanic, not to save money, but to avoid cluttering the deck to provide more space for the passengers as the ships were also claimed to be unsinkable.[18] Following the sinking of Titanic, more lifeboats were added to Olympic (some lifeboats might be from the foundered Titanic[17]) to make sure that safety came first. Britannic, meanwhile, was equipped with eight special large davits to be able to launch many lifeboats at the same time.

    Features

    The three vessels had similar but a little different level of passenger accommodation. However, no class was neglected. The first class passengers enjoyed luxurious cabins, some were equipped with bathrooms. The two most luxurious even included a private promenade deck [Note 1]. There were also large dining rooms, a lavish Grand Staircase built only for the Olympic-class ships[19], a Georgian-style smoking room, a Cafe Veranda decorated with palm trees[20], and even a swimming pool, Turkish bath[21], gymnasium[22], and several other places for meals and entertainment.

    The second class also had good accommodations, with individual cabins equipped with beds and radiators. A smoking room, a library, a spacious dining room, and an elevator was available for the second class. It was also expected to propose a gym on board Britannic.[23]

    Finally, the third-class passengers enjoyed reasonable accommodation compared to other ships, if not up to the second and first classes. Instead of large dormitories offered by most ships of the time, the third-class passengers of the Olympic-class lived in cabins containing four, six or eight bunks. The class also had a smokehouse, a common area, and a dining room. Britannic provided third-class passengers more comfort than its two sister ships.[24]

    Olympic

    Olympic was launched on October 20, 1910[25] and commissioned on June 14, 1911.[26] She made her maiden voyage on June 14, 1911. On 20 September of the same year, she collided with the cruiser HMS Hawke in the port of Southampton, leading to her repair back at Harland and Wolff.[27] After the sinking of Titanic, Olympic underwent a number of refinements to improve her safety. She then resumed her commercial service.

    During the First World War, the ship served as a troop transport. On May 12 1918, she rammed and sank the German submarine U-103.[28] Once placed back in the commercial service during 1920, she crossed the Atlantic with two ships seized from Germany, Majestic and Homeric.[16] In 1934, she again sank a ship by a collision with the Nantucket Lightship LV-117, causing the death of the seven occupants of the vessel rammed.[29]

    Following the merger of White Star Line and Cunard Line in 1934, Olympic was taken out of service, and scrapped in 1937.

    Titanic

    Titanic was launched on May 31, 1911,[30] and her commissioning was slightly delayed due to ongoing repairs of Olympic.[31] The ship left the port of Southampton April 10, 1912 for her maiden voyage, narrowly avoiding a collision with SS New York, a ship moored in the port pulled by the propellers of Titanic. After a stopover at Cherbourg, France and another in Queenstown, Ireland, she sailed into the Atlantic with 2,200 passengers onboard (a total capacity of 3,500), under the command of Captain Edward J. Smith bound for New York City. The crossing took place without major incident until Sunday, April 14 at 23:40.[32]

    Titanic struck an iceberg at 41°46′N 50°14′W / 41.767°N 50.233°W / 41.767; -50.233.[33] while sailing about 400 miles south of the Grand Banks of Newfoundland shortly before midnight. The strike and the shock blew the rivets, thus opening a leak in the hull below the waterline. This caused the first five compartments to be flooded while the ship could only stay afloat with four compartments flooded. The ship sank 2 hours and 40 minutes after the collision and with not enough lifeboats for all of the passengers,[17] the 1,517 of the 2,223 people on board were killed, making it one of the deadliest peacetime maritime disasters in history.

    Britannic

    Britannic was launched on 26 February 1914 at the Harland and Wolff shipyard in Belfast and fitting out began.[34] In August 1914, before Britannic could commence transatlantic service between New York and Southampton, World War I began. Immediately, all shipyards with Admiralty contracts were given top priority to use available raw materials. All civil contracts (including the Britannic) were slowed down.

    On 13 November 1915, Britannic was requisitioned as a hospital ship from her storage location at Belfast. Repainted white with large red crosses and a horizontal green stripe, she was renamed HMHS (His Majesty's Hospital Ship) Britannic.[34]

    08:12 on 21 November 1916, The HMHS Britannic struck a mine[Note 2] at 37°42′05″N 24°17′02″E / 37.70139°N 24.28389°E / 37.70139; 24.28389,[35], and sank. 1,036 people were saved. Thirty men lost their lives in the disaster. One survivor, nurse Violet Jessop was notable as having also survived the sinking of the RMS Titanic in 1912, and had also been on board RMS Olympic, when it collided with the HMS Hawke in 1911. The Britannic was the largest ship lost during World War I.[36]

    Legacy

    Wrecks and expeditions

    The sinkings of Titanic and Britannic did not receive the same attention. Because the exact position of the sinking of the Britannic is known and the location is shallow, the wreck was discovered relatively easily in 1975.[37] Titanic, however, drew everyone's attention in 1912. After several attempts, more or less serious, but equally unsuccessful, the wreck was finally located by Jean-Louis Michel of Ifremer and Robert Ballard following a secret mission for the U.S. Navy.[38] The discovery of the wreck occurred on 1 September 1985, at 25 kilometers from the position given of the sinking. The wreck lies about 4,000 meters deep, broken in two. The bow is relatively well preserved, but the stern imploded during the sinking.[Note 3]

    The wreck of Britannic, which is the largest shipwreck in the world, was discovered in 1975 by Jacques-Yves Cousteau. The wreck has a large tear in the front caused by the bend of the bow when the ship rolled over. She has been, after the discovery, regularly seen as part of many other expeditions.[39]

    Cultural heritage

    Museums and exhibitions pay tribute to the ships, and the two tragedies have inspired many movies, novels, and even musicals and video games.

    When decommissioned, Olympic was previously set to be converted into a floating hotel,[40] but the project was canceled. However, its decorative elements were auctioned. The First Class Lounge and part of the Aft Grand Staircase, can be found in the White Swan Hotel, in Alnwick, Northumberland, England. The à la carte restaurant of Olympic is now restored on the Celebrity Millennium.[41]

    The sinking of the Britannic inspired a 2000 film of the same name starred Edward Atterton, Amanda Ryan and Jacqueline Bisset.

    Notes

    1. This last provision was a novelty on board Titanic.
    2. The hypothesis of the sinking caused by a mine was the one that had been accepted by the inquiry following the sinking. However, it's possible that the sinking was caused by a torpedo[1](Accessed March 21, 2009)
    3. On the contrary to the bow, the stern of the ship was not filled with water when it sank, and imploded as a result of the air.
