when did harmony of the seas come out
The success of the first two Oasis-class ships led Royal Caribbean Cruises to order a third ship of the type in December 2012. Harmony of the Seas was floated out on 19 June 2015, began her first sea trials on 10 March 2016, and was delivered to Royal Caribbean on 12 May 2016. After a construction time of 32 months, the ship first set sail on 15 May 2016 from the STX France docks in Saint-Nazaire, viewed by some 70,000 people.
