Viking has agreed a deal with Fincantieri Shipyard to build six new ocean ships.
The agreement with the Italian manufacturer for the new vessels would increase the ship’s ocean fleet to 16 if all the options are taken up.
Viking revealed the six additional ships will be delivered between 2024 and 2027.
In a statement, Viking said the agreement is subject to “specific conditions”.
The announcement comes ahead of Viking’s officially naming its fourth ocean ship, Viking Sun, on March 8 in Shanghai.
The ocean fleet will welcome two more ships in the next two years, including Viking Orion in June 2018.
Ten additional ships are now on order for delivery starting in 2021, which will bring the ocean fleet to 16 vessels by 2027.
Torstein Hagen, Viking’s chairman, said the latest ship order from the line was in response to the positive feedback Viking had from its passengers and the industry.
He said: “As we continue to expand our brand, we look forward to bringing guests to more destinations around the world and introducing them to the Viking way of exploration.”
