RMS Olympic Ismay had previously planned to build a ship named "Olympic" as a sister ship to . The senior Ismay died in 1899 and the order for the ship was cancelled. Construction of "Olympic" began three months before "Titanic" to ease pressures on the shipyard. Several years would pass before "Britannic" would be launched. In order to accommodate the construction of the class, Harland and Wolff upgraded their facility in Belfast; the most dramatic change was the combining of three slipways into two larger ones. "Olympic" and "Titanic" were constructed side by side. "Olympic"s keel was laid on 16 December 1908

"Olympic" was the largest ocean liner in the world for two periods during 1911–13, interrupted only by the brief tenure of the slightly larger (which had the same dimensions but higher gross tonnage owing to revised interior configurations), before she was then surpassed by . "Olympic" also retained the title of the largest British-built liner until was launched in 1934, interrupted only by the short careers of her slightly larger sister ships. The "Olympic" was withdrawn from service and sold for scrap in 1935; demolition was completed in 1937. Decorative elements of "Olympic" were removed
