Cunard Line will get a new ship in 2022, increasing its fleet to four ships for the first time since 1998.
The 113,000-gross-ton ship will be built at a Fincantieri shipyard in Italy. It will fit in size midway between Cunard's two smaller 90,000-ton ships and its 151,800-ton flagship, Queen Mary 2.
Cunard said the ship will carry up to 3,000 passengers but wasn't clear about what its capacity would be at double occupancy.
A rendering shows a prominent stack of upper decks towards the front of the ship and Cunard's trademark red funnel at the rear. As with the other Cunard ships, the superstructure is white and the hull black.
Cunard's most recent ship, the 2,092-passenger Queen Elizabeth, arrived in 2010.
The new Cunard ship would be the line's 249th in a series that stretches back to its founding by Canadian Samuel Cunard in 1839.
