Viking Ocean Cruises

(9:05 a.m. EST) -- Viking Ocean Cruises and Fincantieri, one of the largest shipbuilders in the world, have agreed to expand Viking's new ocean ship order by six ships. That brings the total of Viking's ship orders and options to 16.

Should Viking exercise all of its new options, Fincantieri will deliver the six new cruise ships between 2024 and 2027. Viking is currently sailing four ships, with Viking Orion debuting in 2018 and Viking Jupiter in 2019. A previous agreement has additional new-builds slated to debut in 2021, 2022 (two ships) and 2023. (For more on ultra-premium and luxury new-builds coming soon, see our list of cruise ships on order.)

According to Fincantieri's press release, the six new ships agreed on this week will follow a similar design to Viking's existing 930-passenger, 47,800-ton, all-balcony upscale cruise ships, but will tweak plans to incorporate the latest technologies available.

Viking Ocean Cruises' most recently debuted ship, Viking Sun, is currently sailing the line's first (and sold out) world cruise, and will be officially christened on March 8 in Shanghai.
