The RMS Titanic was not on her own, there were 2 sister ships of Titanic. This Atlantic liner was conceived as an idea for 1 of 3 super liners which would be built for both luxury and speed, they would be known as the Olympic Class Liners. The Olympic Class Liners were conceived by White Star Line managing director, J. Bruce Ismay and built by the Belfast based Harland & Wolff ship builders. The 3 ships were to be the next "big thing" to come out of the company since the big 4 (RMS Oceanic, RMS Atlantic, RMS Baltic and RMS Adriatic), they were marketed to compete with the Mauritania and Lusitania launched by a rival company, Cunard Line.
The 3 ships would be built over a short period of just a few years and would start with the RMS Olympic, then the RMS Titanic, finally followed by the HMHS Britannic (formerly due to be known as the RMS Britannic).
