RMS Olympic retained the title of the largest British-built liner until RMS Queen Mary was launched in 1934, interrupted only by the short careers of her slightly larger sister ships, i.e Titanic and Britannic.

On the night of 14/15 April 1912, Titanic collided with an iceberg in the North Atlantic and sank.Britannic struck a mine and sank in the Kea Channel (Greece) in the Mediterranean on 21 November 1916.

Following completion, Olympic started her sea trials on 29 May 1911, which she successfully completed.Her maiden voyage commenced on 14 June 1911 from Southampton, calling at Cherbourg and Queenstown, reaching New York City on 21 June.As the First World War began. Olympic initially remained in commercial service. As a wartime measure, Olympic was painted in a grey colour scheme, portholes were blocked, and lights on deck were turned off to make the ship less visible.

By the time of her retirement, Olympic had completed 257 round trips across the Atlantic, transporting 430,000 passengers on her commercial voyages, travelling 1.8 million miles
