[8] On 30 July 2014, Carnival Corporation announced it was ordering the third Royal-class vessel for Princess, at a cost of €600 million.

[9][10] In March 2015, Carnival Corporation signed a strategic agreement with Fincantieri, which included the fourth and fifth Royal-class vessels for Princess.

[12] In January 2017, Carnival Corporation signed a memorandum of agreement with Fincantieri for the sixth and final Royal-class ship for Princess.

[13] The two first ships of the Royal class were designed to have a gross tonnage of 141,000 GT, with a passenger capacity of 3,600.

The new ships were predicted to enter service in mid-2013 and 2014 and were to become the largest new-build vessels to date for Princess Cruises.

[6] Design features were planned to evolve from existing Princess staples, such as an expanded "Piazza" central atrium as well as an expansion in balcony accommodations, which would become available across 80% of all staterooms on the vessels.

The ship was officially handed over to Princess on 30 May 2013 and christened by Catherine, Duchess of Cambridge on 13 June 2013.
