On armoured warships, the heavily armoured section of the ship that protects the ammunition and machinery spaces is called the [[armoured citadel]].

A modern naval interpretation refers to the heaviest protected part of the hull as "the vitals", and the citadel is the semi-armoured freeboard above the vitals. Generally, Anglo-American and German languages follow this while Russian sources/language refer to "the vitals" as цитадель "citadel". Likewise, Russian literature often refers to the turret of a tank as the 'tower'.

The [[safe room]] on a ship is also called a citadel.
