Upon "Caroline"s decommissioning in 2011, her future was uncertain. Proposals were made to return the ship to her First World War appearance, which among other things would have involved sourcing and installing 6-inch (152.4 mm) and 4-inch (102 mm) guns of that era and removing the large deckhouse from her midships deck. One proposal considered was to remain in Belfast as a museum ship within the Titanic Quarter development alongside . Another was a move to Portsmouth, with many of her original fittings restored to return her as much as possible to her First World War appearance.
