The vessel will now sail to Valletta in Malta where it will be officially named on 17 May by its ceremonial godmother, Fiona Carnarvon.
The ship will then offer itineraries in the Mediterranean, Scandinavia and northern Europe before repositioning at the end of the year for voyages around Australia and New Zealand.
Torstein Hagen, chairman of Viking, said: "As we celebrate our 25th anniversary and a year of important milestones for Viking, today we are very proud to welcome the newest ocean ship to our award-winning fleet.
"Lady Carnarvon has honoured us by serving as godmother to the Viking Mars, and we look forward to welcoming guests onboard this beautiful new sister ship in the coming weeks."
