The new ships, which are expected to have around 1,250 staterooms, will be 1,000 feet long and 200 feet high, and will be built at the Meyer Werft shipyard in Germany.

The line said the ships would be “slightly larger” than the current newest Disney ships – Disney Dream and Disney Fantasy – which were launched in 2011 and 2012.

It added that “design plans, ship names and itineraries are still in development, [but that] the Walt Disney Imagineering team is already dreaming up exciting new innovations that will be uniquely fun and distinctly Disney”.

“We pride ourselves on the unforgettable vacation experiences we deliver to our guests each and every day, and the expansion of our Disney fleet will allow us to create even more magical memories for families at sea and in incredible cruise destinations around the world,” said Robert Iger, chairman and chief executive, The Walt Disney Company.
