MSC Constellation Class: Rumored Mega-Ships
MSC Cruises could eventually build some of the largest cruise ships the world has ever seen.
Reports have been circulating about a potential new ship class known as MSC Constellation Class, with ships reportedly reaching around 265,000 gross tons and measuring approximately 365 meters long. If built to those specifications, they could be even larger by gross tonnage than Royal Caribbean’s Icon Class.
But there is one very important thing to know: MSC has not officially announced Constellation Class.
As of July 2026, the project remains unconfirmed. The name, size, number of ships, shipyard, and other details come from industry reports rather than an official MSC Cruises announcement.
So what do we actually know, what is still rumor, and how would these ships compare to MSC World Class and Royal Caribbean Icon Class?
Quick Answer: What Is MSC Constellation Class?
MSC Constellation Class is the unofficial name being used for a rumored new class of ultra-large MSC cruise ships.
Industry reports have suggested that MSC was in talks with Meyer Turku in Finland to build four ships measuring around 265,000 gross tons and approximately 365 meters long.
If those numbers are accurate, the ships could surpass Royal Caribbean’s Icon Class in gross tonnage and become some of the largest cruise ships ever built.
Quick answer: MSC Constellation Class could be a future four-ship mega-ship project of around 265,000 gross tons, but MSC has not officially confirmed the class.
Is MSC Constellation Class Official?
No. MSC Cruises has not officially announced a Constellation Class order.
That is the most important distinction when discussing this project. Unlike MSC World Class or the newly announced New Frontier Class, there has been no official MSC press release confirming Constellation Class, no confirmed ship names, no delivery dates, and no published deck plans.
Reports about the project first gained attention after claims that MSC was in talks with Meyer Turku to develop a new ultra-large ship platform.
Until MSC or Meyer Turku makes a formal announcement, Constellation Class should be treated as a rumored project.
See our post on MCS's New Frontier Class Ships for more information on that!
How Big Could MSC Constellation Class Be?
The reported specifications are what made this project so interesting in the first place.
| Feature | Reported MSC Constellation Class Details |
|---|---|
| Gross tonnage | Around 265,000 GT |
| Length | Around 365 meters |
| Number of ships | Reportedly four |
| Builder | Reportedly Meyer Turku in Finland |
| Passenger capacity | Not officially confirmed |
| Status | Rumored and unconfirmed |
At approximately 265,000 gross tons, Constellation Class would be considerably larger than MSC World America and slightly larger by gross tonnage than Royal Caribbean’s Icon of the Seas.
That would put MSC in direct competition for the title of world’s largest cruise ship.
MSC Constellation Class vs Icon Class
The most obvious comparison is with Royal Caribbean’s Icon Class.
Icon of the Seas is approximately 250,800 gross tons, 1,196 feet long, and can carry up to 7,600 guests. The rumored Constellation ships have been reported at approximately 265,000 gross tons and 365 meters, or about 1,198 feet, in length.
| Feature | Rumored MSC Constellation Class | Royal Caribbean Icon Class |
|---|---|---|
| Gross tonnage | Around 265,000 GT | Around 250,800 GT |
| Length | Around 365 meters | Around 365 meters |
| Maximum capacity | Not confirmed | Up to 7,600 guests |
| Status | Rumored | Sailing |
| Number of ships | Reportedly four | Multiple ships sailing or planned |
Based purely on the reported gross tonnage, Constellation Class could be larger than Icon Class. But passenger capacity has never been officially confirmed, so claims that it would carry more guests should be treated cautiously.
The bigger question is not just how large these ships would be, but what MSC would actually do with all that space.
Who Would Build MSC Constellation Class?
Reports have linked the rumored Constellation Class to Meyer Turku in Finland.
Meyer Turku is one of the most important cruise shipbuilders in the world and is also responsible for building Royal Caribbean’s Icon Class ships.
That makes the rumor especially interesting. If MSC chose Meyer Turku for a ship larger than Icon Class, the same shipyard could potentially build the vessels that challenge its own previous size records.
However, no official order between MSC Cruises and Meyer Turku for Constellation Class has been announced.
Is Constellation Class the Same as New Frontier Class?
No. Based on everything officially announced so far, New Frontier Class is a separate project.
MSC officially announced New Frontier Class with Meyer Werft in Papenburg, Germany. That project covers four ships plus options for two more, with vessels expected to be around 180,000 gross tons and carry up to 5,400 guests.
The first New Frontier ship is expected in 2030.
| Feature | Constellation Class | New Frontier Class |
|---|---|---|
| Status | Rumored | Officially announced |
| Reported size | Around 265,000 GT | Around 180,000 GT |
| Builder | Reportedly Meyer Turku, Finland | Meyer Werft, Germany |
| Number of ships | Reportedly four | Four plus two options |
| First delivery | Unknown | Planned from 2030 |
This is an important difference because some online sources have blurred the two projects together. The reported Constellation project involved much larger ships and a different shipyard.
How Would Constellation Compare to MSC World Class?
MSC World Class is currently the cruise line’s largest confirmed ship platform. It includes MSC World Europa, MSC World America, MSC World Asia, MSC World Atlantic, and additional ships on order.
MSC World America is around 216,000 gross tons, meaning a 265,000-ton Constellation ship would represent a major jump in size.
| Ship Class | Approximate Gross Tonnage |
|---|---|
| MSC Constellation Class | 265,000 GT, rumored |
| Royal Caribbean Icon Class | 250,800 GT |
| MSC World Class | Around 216,000 GT |
| MSC New Frontier Class | Around 180,000 GT |
If the Constellation reports are accurate, these would not simply be slightly larger World Class ships. They would represent an entirely new scale for MSC.
How Many Constellation Class Ships Could Be Built?
Reports have generally pointed to a possible series of four ships.
No options, delivery dates, ship names, or construction timetable have been officially announced.
That means even the four-ship figure should be considered provisional until MSC confirms the project.
Would Constellation Class Have MSC Yacht Club?
Nothing has been officially announced about MSC Yacht Club on Constellation Class.
Still, it would be very surprising for MSC to build a brand-new ultra-large flagship without Yacht Club. Yacht Club has become one of MSC’s most important premium products and is featured prominently on its newest large ships.
On a 265,000-ton vessel, MSC could potentially create its largest Yacht Club ever, with more accommodations, larger private outdoor areas, additional dining, and new premium spaces.
But for now, all of that is speculation.

What Could MSC Put on a Ship This Large?
MSC has not announced any onboard features for Constellation Class, but the size creates some interesting possibilities.
World Class already includes large promenades, family districts, waterparks, entertainment venues, specialty restaurants, pools, outdoor spaces, and MSC Yacht Club.
A Constellation ship could potentially go much further.
- Larger family districts
- Bigger waterparks and thrill attractions
- New outdoor neighborhoods
- More restaurants and bars
- Expanded entertainment venues
- A larger MSC Yacht Club
- More pools and outdoor decks
- New cabin categories
- More distinct neighborhoods or districts
Again, none of these features have been confirmed. Until MSC reveals the actual design, we do not know whether Constellation would resemble World Class, compete directly with Icon Class, or introduce something completely different.
When Could MSC Constellation Class Launch?
No official delivery timeline has been announced.
MSC already has a very busy shipbuilding pipeline. The cruise line has additional World Class ships scheduled through 2031 and New Frontier Class deliveries planned to begin in 2030.
That makes the potential timing of Constellation Class one of the biggest unanswered questions.
If the project is still alive, it would likely need to fit around both MSC’s own expansion plans and available shipyard capacity.
Could Constellation Class Still Happen?
Absolutely, but there is currently no guarantee.
MSC has shown that it is willing to invest heavily in fleet expansion. It is adding more World Class ships, launching New Frontier Class, growing in North America, and continuing to invest in destinations like Ocean Cay.
At the same time, the fact that Constellation Class has not received an official announcement means we should be careful not to present reported specifications as confirmed facts.
The project may still be under consideration, could have changed significantly, could be delayed, or may never move forward in the form originally reported.
My Take on MSC Constellation Class
Constellation Class is fascinating because it shows just how ambitious MSC could be.
A 265,000-ton MSC ship would immediately become one of the biggest stories in cruising. It would put MSC into an even more direct battle with Royal Caribbean’s Icon Class and create huge questions about what the cruise line could do with that much space.
Personally, I hope MSC focuses on more than simply carrying more passengers. What would make Constellation really interesting is better space per guest, more outdoor areas, larger lounges, expanded Yacht Club spaces, and new experiences that feel genuinely different from World Class.
Bigger ships are exciting, but how MSC uses the extra space would matter much more than simply winning the title of world’s largest cruise ship.
What We Still Do Not Know
- Whether Constellation Class will actually be built
- Whether Constellation is the final class name
- Final gross tonnage
- Passenger capacity
- Ship names
- Delivery dates
- Deck plans
- Onboard attractions
- Dining venues
- Yacht Club design
- Homeports
- Itineraries
- Whether any ships would sail from the United States
- Whether they would visit Ocean Cay
Right now, the reported size and possible Meyer Turku connection are the most interesting details, but almost everything about the actual guest experience remains unknown.
Final Thoughts on MSC Constellation Class
MSC Constellation Class could become one of the biggest cruise ship projects ever built, but for now, it remains a rumor.
Reports suggest a possible four-ship class of approximately 265,000 gross tons and 365 meters in length, potentially making the ships larger by gross tonnage than Royal Caribbean’s Icon Class.
However, MSC has not officially confirmed the project, placed a publicly announced order, revealed ship names, released deck plans, or provided a launch date.
The best way to think about Constellation Class right now is as a fascinating possibility rather than a confirmed future MSC ship class.
And if MSC does eventually make it official, the biggest question may not be whether it becomes the world’s largest cruise ship. The real question is what MSC will do with all that space.
