Prima-class cruise ship
class of cruise ships built for Norwegian Cruise Line
Prima-class cruise ships (, PREE-mah), formerly known by the project name Project Leonardo, are a class of cruise ships built for Norwegian Cruise Line (NCL). These are the first NCL ships to be built by Fincantieri. Each ship is expected to cost about $850 million. The modifications that are to be made to the design of the future Prima-class ships would result in an extra 1.2 billion euros in shipbuilding costs — about US$1.27 billion.
The first ship, Norwegian Prima, entered service in 2022, with the second, Norwegian Viva, in 2023.
The third ship Norwegian Aqua, the first in the Prima plus subclass entered the fleet in 2025 and was around 10 percent bigger in gross tonnage than the Norwegian Prima. The fourth Prima plus class ship, Norwegian Luna debuted in March 2026.
The upcoming fifth ship Norwegian Aura and sixth unnamed Prima plus plus subclass ships will be 20 percent larger than Norwegian Prima, making them the largest in the entire fleet, and they will debut in 2027 and 2028. The Prima plus plus ships will be wider and longer than Norwegian Prima.
