On 11 February 2011, Royal Caribbean announced that they had ordered a new class of ships from the Meyer Werft shipyard in Papenburg, Germany, the first of which was scheduled to be delivered by autumn 2014.
At the time, the project was code-named "Project Sunshine".
Later that year, two 20.5-megawatt ABB Azipod XO propulsion units were ordered for that ship.

On 29 February 2012 the company announced that a second "Project Sunshine" ship had been ordered and would be delivered by Spring 2015, and ordered identical Azipod propulsion units shortly thereafter.
Just under a year later, on 31 January 2013, Royal Caribbean announced the official name of the new class of ships, Quantum Class, as well as the names of the first two ships in the class, Quantum of the Seas and Anthem of the Seas.
