Construction Nears for Carnival’s Biggest Cruise Ship Ever

Carnival Cruise Line is preparing to take a major step in its fleet expansion as construction is expected to begin this month on the first Project Ace vessel, a next-generation mega-ship projected to be the largest cruise ship ever built for the brand and a new high-water mark in the company’s long partnership with Italian shipbuilder Fincantieri.

A New Flagship Class for Carnival

Publicly available information from Carnival Corporation and Fincantieri indicates that Project Ace represents an all-new class of liquefied natural gas powered cruise ships, with the first unit scheduled for delivery around 2029. Industry reporting describes the prototype as a roughly 230,000-gross-ton vessel designed to accommodate up to about 8,000 guests at full capacity, significantly larger than Carnival’s current Excel-class ships, which measure about 180,000 gross tons.

The Project Ace platform will therefore surpass existing Carnival vessels such as Mardi Gras, Carnival Celebration and Carnival Jubilee, which currently rank among the largest in the fleet. While Carnival has steadily grown ship size over several decades, this is the first time the brand has moved into a size category that approaches the very largest cruise ships in the world.

Separate coverage of the global cruise orderbook shows the Project Ace prototype listed among the biggest vessels currently on order, with the Carnival ship noted as the largest vessel ever to be constructed in Italy. The newbuild is part of a wider strategy by Carnival Corporation to add one to two ships per year into the 2030s, while maintaining a measured approach to capacity growth after the rapid expansion of the 2000s.

Fincantieri’s Largest Cruise Ship to Date

Details from Fincantieri’s agreement with Carnival Corporation describe the Project Ace units as the largest cruise ships the Italian builder has ever undertaken. Earlier generations of Carnival vessels such as the Vista class already ranked as record-setting projects for the yard at the time of their delivery, but the scale of the new class will exceed those ships by a substantial margin.

The Project Ace prototype will be built at one of Fincantieri’s major Italian shipyards, where the yard has previously delivered large vessels for several Carnival Corporation brands, including Princess Cruises and Holland America Line. Reports on the deal emphasize that the order helps secure a significant workload for Italian shipyards well into the next decade and reinforces the builder’s position in the market for very large, LNG-powered cruise ships.

Construction typically begins with a steel-cutting ceremony, followed by keel laying as large pre-fabricated blocks are joined in drydock over many months. Industry observers expect the formal start of work on the first Project Ace ship to follow this standard sequence, with the initial steel blocks for the hull and superstructure entering production this month as yard schedules transition from design to physical assembly.

How Project Ace Compares in the Global Mega-Ship Race

Even as Project Ace will become Carnival Cruise Line’s largest ship to date, it will enter a competitive landscape in which several rival brands already operate or are building vessels above 200,000 gross tons. The world’s largest cruise ships today include Royal Caribbean International’s Icon and Oasis class vessels, which exceed 240,000 gross tons and are cited in public registries as the biggest cruise ships currently afloat.

Data compiled in global lists of the largest cruise ships show that, once delivered, the first Project Ace ship would place Carnival closer to the upper end of the size rankings, although still slightly below the very largest units in terms of gross tonnage. The move nonetheless marks a clear shift in Carnival’s fleet profile toward larger, more amenity-rich ships capable of hosting a wide range of attractions and experiences on board.

Analysts note that the expansion into this size category mirrors a broader industry trend as major cruise groups seek efficiencies of scale, higher revenue potential per sailing and new onboard features that require additional space. Project Ace is positioned as Carnival’s answer to that competitive dynamic, tailored to the brand’s mass-market focus and emphasis on entertainment-driven vacations.

Design, Capacity and Guest Experience

While full design renderings have not yet been widely disseminated, publicly reported specifications and early descriptions suggest that Project Ace will introduce a new layout compared with the Excel class, with additional passenger decks, expanded family and suite accommodations, and a larger outdoor recreation footprint. Coverage of Carnival’s plans indicates that the ships will integrate advanced energy-efficiency technologies alongside their LNG propulsion systems, aligning with the company’s stated emissions-reduction goals.

The projected capacity of up to around 8,000 guests at full occupancy places the Project Ace prototype in line with the largest contemporary mega-ships, which typically combine multiple pool areas, water parks, entertainment venues, expansive dining options and dedicated spaces for children and teens. Observers expect Carnival to introduce new themed zones and attractions unique to this class, building on the neighborhood-style concepts that first appeared on its Excel-class vessels.

Carnival has been gradually reshaping its fleet mix, adding larger, more efficient ships while retiring or transferring older tonnage. The forthcoming Project Ace class is viewed within the industry as a key element of that strategy, creating a new flagship platform that could serve popular homeports in North America and potentially support deployment to private destinations in the Caribbean.

Timeline and What Comes Next

Based on the multi-year construction timelines typical for ships of this size, work beginning this month points toward delivery of the first Project Ace vessel near the end of the decade. The build process will encompass several major phases, from hull assembly and superstructure completion to interior outfitting, systems testing and sea trials prior to handover to Carnival Cruise Line.

Carnival Corporation’s recent financial updates indicate that the group plans to maintain a disciplined newbuild schedule, with Project Ace forming part of a broader orderbook that includes additional ships for Carnival Cruise Line and other brands such as AIDA. Industry reporting suggests that follow-on units in the Project Ace series could be spaced over several years, providing Carnival with flexibility to match deployment of the new class to market demand.

As steel cutting and block construction get underway, attention within the cruise sector is expected to focus on how Carnival differentiates this class in a market already familiar with very large, amenity-packed ships. The Project Ace prototype is set to become a visible symbol of Carnival’s post-pandemic fleet renewal, signaling the brand’s intention to compete at the top tier of the global cruise market with its largest, most technically advanced ship yet.
