Context_1 : RMS Republic was a steam-powered ocean liner built in 1903 by Harland and Wolff in Belfast, and lost at sea in a collision six years later while sailing for the White Star Line. A CQD distress call was issued on the new Marconi radio device, the first recorded, resulting in the saving of around 1500 lives. Known as the "Millionaires' Ship" on account of the number of well-known and immensely rich Americans who traveled by her, she was described as a "palatial liner" and was the flagship of White Star Line's Boston service. Context_2 : The RMMV (Royal Mail Motor Vessel) Oceanic was the planned name of an unfinished ocean liner that was partially built by Harland and Wolff for the White Star Line. The ship was to have been the first 1000 ft -long ocean liner. It was intended to be the largest ocean liner for the White Star Line, thus it would have been larger than the earlier White Star giants, "Olympic", "Titanic", "Britannic", and "Majestic". Context_3 : The "Olympic"-class ocean liners were a trio of British ocean liners built by the Harland & Wolff shipyard for the White Star Line during the early 20th century. They were "Olympic" (1911), "Titanic" (1912), and "Britannic" (1915). All three were designed to be the largest and most luxurious passenger ships in the world, designed to give White Star an advantage in the transatlantic passenger trade. Two were lost early in their careers: "Titanic" sank in 1912 on its maiden voyage, after hitting an iceberg in the North Atlantic Ocean, and "Britannic" in 1916, after hitting a mine laid by the minelayer submarine "U-73" in a barrier off Kea in the Aegean Sea during World War I. "Olympic", the lead vessel, had a career spanning 24 years and was retired in 1934 and sold for scrapping in 1935. Context_4 : RMS "Olympic" ( ) was a British transatlantic ocean liner, the lead ship of the White Star Line's trio of "Olympic"-class liners. Unlike her younger sister ships, "Olympic" had a long career, spanning 24 years from 1911 to 1935. This included service as a troopship during the First World War, which gained her the nickname "Old Reliable". "Olympic" returned to civilian service after the war and served successfully as an ocean liner throughout the 1920s and into the first half of the 1930s, although increased competition, and the slump in trade during the Great Depression after 1930, made her operation increasingly unprofitable. Context_5 : RMS "Mauretania" was launched on 28 July 1938 at the Cammell Laird yard in Birkenhead, England, and was completed in May 1939. The second "Mauretania" was the first ship built for the newly formed Cunard White Star company following the merger in April 1934 of the Cunard and White Star Line. On the withdrawal of the first RMS "Mauretania" in 1934, to prevent a rival company using the name and to keep it available for the new liner, arrangements were made for the Red Funnel paddle steamer "Queen" to be renamed "Mauretania" in the interim. Context_6 : SS "Traffic" was a tender of the White Star Line, and the fleetmate to the SS "Nomadic". She was built for the White Star Line by Harland and Wolff, at Belfast, to serve the luxury "Olympic"-class ocean liners. SS "Traffic" ferried some of the third class passengers to  for her maiden voyage. She served as a tender for White Star, as a minesweeper for the French Navy between 1917 and 1919, and supported troop ships at the end of the First World War. After the war she was sold to Société Cherbourgeoise Transbordement, and later renamed "Ingénieur Reibell". She was scuttled by the French as the Germans invaded in 1940, but was salvaged and used by the Germans as an armed coastal vessel until being sunk by the Royal Navy on 17 January 1941. Context_7 : SS "Nomadic" is a former tender of the White Star Line, launched on 25 April 1911 in Belfast now on display in Belfast's Titanic Quarter. She was built to transfer passengers and mail to and from RMS "Olympic" and RMS "Titanic", and is the only White Star Line vessel in existence today. Context_8 : RMS "Homeric", originally launched as "Columbus", was built for Norddeutscher Lloyd and launched in 1913 at the F. Schichau yard in Danzig. "Columbus" was ceded to Great Britain in 1919 as part of German war reparations. She was sold to White Star Line in 1920, which named her "Homeric". Her sister ship "Hindenburg" retained her German ownership and was renamed "Columbus". "Homeric" was operated by White Star from 1922 to 1935. Context_9 : RMS "Titanic" ( ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning hours of 15 April 1912, after it collided with an iceberg during its maiden voyage from Southampton to New York City. There were an estimated 2,224 passengers and crew aboard the ship, and more than 1,500 died, making it one of the deadliest commercial peacetime maritime disasters in modern history. The RMS "Titanic" was the largest ship afloat at the time it entered service and was the second of three "Olympic"-class ocean liner s operated by the White Star Line. The Titanic was built by the Harland and Wolff shipyard in Belfast. Thomas Andrews, her architect, died in the disaster. Context_10 : RMS "Atlantic" was a transatlantic ocean liner of the White Star Line that operated between Liverpool, United Kingdom, and New York City, United States. During the ship's 19th voyage, on 1 April 1873, she ran onto rocks and sank off the coast of Nova Scotia, Canada, killing at least 535 people. It remained the deadliest civilian maritime disaster in the North Atlantic Ocean until the sinking of  on 2 July 1898 and the greatest disaster for the White Star Line prior to the loss of "Titanic" in April 1912. fact_1 : RMS "Olympic" ( ) was a British transatlantic ocean liner, the lead ship of the White Star Line's trio of "Olympic"-class liners. fact_2 : The "Olympic"-class ocean liners were a trio of British ocean liners built by the Harland & Wolff shipyard for the White Star Line during the early 20th century. Question: Which shipmaker built the RMS Olympic for the White Star Line during the early 20th century?
Output: Harland  Wolff shipyard
