Norwegian Cruise Line (NCL) is going ahead with orders for two more vessels worth a combined EUR 1.6bn ($1.86bn) at Fincantieri in Italy.

The Project Leonardo Class ships will be the fifth and sixth in a series inked last year.

Delivery will take place in 2026 and 2027.

“These orders extend our disciplined and measured newbuild programme and strong growth trajectory well into the future and will further drive long-term returns for our shareholders,” said Frank Del Rio, president and CEO of NCL.

“Our six-ship Leonardo Class fleet will allow us to broaden our deployment into strong performing and mature un-served and under-served markets and offer new experiences to our guests.”

The 140,000-gt vessels will accommodate 3,300 passengers.

A priority of the prototype design is energy efficiency, with the aim of optimising fuel consumption and reducing the impact on the environment, the company said.

NCL now has seven vessels on order, including one at Meyer Werft in Germany, plus another for its Regent Seven Seas Cruises brand.

It still has to enter into financing agreements for the latest two.

The Fincantieri ships are intended to form the backbone of the future NCL fleet.
