Overview
Britannia is the flagship of P&O Cruises and the third ship to carry one of the most resonant names in the company's history. Built by Fincantieri at Monfalcone, Italy, she entered service on 14 March 2015, having been named four days earlier by Queen Elizabeth II — the most prestigious christening available to a British cruise ship, and a deliberate statement that, at 143,730 GT, the largest ship yet built for the British market was also an heir to P&O's nineteenth-century heritage.
She is a Royal-class ship: the P&O adaptation of the platform Princess Cruises introduced with Royal Princess, rebuilt in P&O's image with a different character, different interiors and the largest Union Flag ever applied to a ship's bow — 94 metres of it — painted across her prow.
Key specifications
The dataset records Britannia at 143,730 GT, 330.0 metres long, with a maximum capacity of 3,647 passengers, a service speed of 22 knots and hull number 6231. Wikipedia's figures agree on tonnage, length and capacity, and add a crew of 1,398, 15 passenger decks, and installed power of 62 MW from four Wärtsilä engines in a diesel-electric arrangement.
One dataset dimension should be treated with care: the beam is listed as 44.0 metres, whereas Wikipedia and the ship's technical summaries give a hull beam of 38.4 metres. The larger figure may reflect an extreme width measurement rather than the moulded beam, but as published figures go, 38.4 metres is the beam of record, and the discrepancy is logged in the batch notes.
Design and construction
Britannia was ordered in 2011 and laid down on 15 May 2013 at Fincantieri's Monfalcone yard. She is based on the Royal-class template developed for Princess Cruises — a large, balcony-heavy design with a central piazza-style atrium — but was extensively reworked for P&O: contemporary British interior design, a different funnel and livery treatment, and the celebrated Union Flag bow, at 94 metres the largest of its kind in the world.
The dataset gives her launch year as 2015, the year of her completion and entry into service. Her ceremonial float-out at Monfalcone in fact took place on 14 February 2014, with the traditional champagne bottle smashed against the hull; she was completed on 26 February 2015 and sailed from the yard for Southampton via Gibraltar at the end of that month. The float-out date is the launch date in most ship records, and the difference is logged in the batch notes.
Naming, launch and maiden voyage
The name was announced on 24 September 2013, with its pedigree spelled out: the first P&O-connected Britannia had entered service in 1835 for the General Steam Navigation Company, an ancestor of P&O; the second, of 1887, was one of four ships ordered to mark the golden jubilee of both Queen Victoria and P&O itself.
The naming ceremony matched the claim. On 10 March 2015, at the Ocean Terminal in Southampton, Queen Elizabeth II officially named the ship — a distinction shared by few cruise ships. Her first captain was Paul Brown. Her maiden voyage began on 14 March 2015, a two-week cruise to Spain, Italy and France, exactly as the dataset records.
Career by operator
Britannia has served a single operator under a single name.
| Name | Operator | Years |
|---|---|---|
| Britannia | P&O Cruises | 2015–present |
She took the role of fleet flagship from Oriana on entering service and has been the centrepiece of P&O's mainstream programme ever since, working the brand's core pattern of European cruising in the summer seasons and longer Caribbean voyages in winter during her early years. There has been no renaming, transfer or charter; the dataset's single-operator history is the whole story.
Onboard character
Britannia's design brief was contemporary British style without liner nostalgia. She was the first P&O ship on which every outside cabin had a balcony — a quietly radical step that defined the balcony-era standard for the fleet. Inside, the Royal-class piazza atrium was reworked in a cooler, more urban register than Princess's version, and the ship made food a headline feature, with dining and cookery associated with celebrity chefs of the period and a dedicated cookery school, the Cookery Club, as a signature space.
Externally her character is set by two funnels in P&O blue and that enormous Union Flag sweeping the bow — a patriotic livery statement that made her instantly recognisable in any port. Four pool areas, including a dedicated teenagers' pool, and the Oasis Spa completed the launch-era identity of a flagship designed to feel modern, British and unmistakably P&O.
Major refits and incidents
Her most substantial recorded refurbishment came in 2024, a multi-million-pound refit after nine years in service that renewed entertainment and bar venues including the Sunset Bar, Crystal Room, Brodie's and the Crow's Nest, added new dance floors, refreshed the spa and salon, the Lido and Serenity pool areas and the children's splash zone, and upgraded crew areas — a hotel refresh rather than structural alteration, typical of a flagship kept at the front of the fleet.
No major casualty is recorded against Britannia in the sources consulted for this guide.
Sister ships and class
She is the P&O member of the Royal class, the platform whose lead ship is Princess Cruises' Royal Princess (2013), followed by Regal Princess (2014) and Majestic Princess (2017), with later and larger developments in the same family for Princess. Britannia shares the platform's bones — hull form, balcony-heavy superstructure and piazza arrangement — while differing markedly in exterior treatment and interior character. She has no sister within the P&O fleet itself; the fleet's next step in size, Iona and Arvia, belong to the unrelated Excellence class.
Fate and where she is now
The dataset records her status as active. Britannia remains in service as flagship of P&O Cruises under her original name — a ship in settled mid-career, her 2015 entry into service still recent enough that her history is one of continuity rather than change.
