The announcements were made during the Horizons: D23 Disney Experiences Showcase at the weekend (15 August) as DCL pursues its plan to expand its fleet to 13 ships by 2030.
The first ship in the new class, plans for which currently comprise three ships in total, will enter service in 2029 aiming to occupy a new "sweet spot" size category for the brand.
Larger than Disney Magic and Disney Wonder but smaller than its new newer Wish-class vessels, DCL said the ships are designed to give Disney "greater flexibility to explore new destinations and reach new markets".
Further details of the ships and their itineraries are yet to be revealed.
