The 145,000 GT-vessel was ordered in January 2017 with Italian shipbuilder Fincantieri and her steel-cutting was performed on 14 February 2019 in Castellammare di Stabia, Italy.

Originally expected to begin operations in November 2021, the ship saw her construction and subsequent delivery delayed amid the COVID-19 pandemic and its impact on Fincantieri and Carnival Corporation.

Discovery Princess operated her week-long inaugural voyage on 27 March 2022 from her debut homeport of Los Angeles to the Mexican Riviera and moved to Seattle during her maiden summer deployment to cruise the Inside Passage.

[4] In January 2017, Carnival Corporation finalized the order for a sixth Royal-class ship for Princess Cruises to be built at Fincantieri's shipyard in Monfalcone, Italy.

She was then scheduled to perform a 50-day circumnavigation cruise around South America in late-2021 to reach her destined homeport of Los Angeles in early-2022, where she would sail along the Mexican Riviera and the California coast.

[17] In order to reach Los Angeles, the ship left the shipyard in Italy in February 2022 by sailing eastwards via the Suez Canal and made a stop in Singapore for additional supplies before embarking on her transpacific voyage.
