First class cruisers

Armoured cruisers were protected by a belt of side armour and an armoured deck. In the Royal Navy this classification was not actually used, the term first class cruiser being used instead for both armoured cruisers and large protected cruisers. Thus, the first class cruisers built between the Orlando class (1886) and the Cressy class (1897) were, strictly speaking, protected cruisers as they lacked an armored belt. The first class cruiser was succeeded by the Battlecruiser.

Protected cruisers

Protected cruisers were so-called because their vital machinery spaces were protected by an armoured deck and the arrangement of coal bunkers. The ships below are all protected cruisers, but were rated as second and third class cruisers by the Royal Navy. The third class cruiser was not expected to operate with the fleet, was substantially smaller than the second class and lacked the watertight double-bottom of the latter. With the advent of turbine machinery, oil firing and better armour plate the protected cruiser became obsolete and was succeeded by the light cruiser.

Scout cruisers

The scout cruiser was a smaller, faster, more lightly armed and armoured cruiser than the protected cruiser, intended for fleet scouting duties and acting as a flotilla leader. The advent of better machinery and larger, faster destroyers and light cruisers effectively made them obsolete.

Light cruisers

The light cruiser succeeded the protected cruiser, as improvements in machinery and armour had made the latter obsolete. The Town class were rated as second class protected cruisers, but were effectively light cruisers with mixed coal and oil firing. The Arethusa class were the first oil-only fired class which meant that the cruiser could no longer rely on the arrangement of coal bunkers in the hull as protection and adopted destroyer machinery for a higher top speed, making them the first true light cruisers. In the London Naval Treaty of 1930, light cruisers were defined as cruisers having guns of 6.1 inch (155 mm) calibre or less, with a displacement not exceeding 10,000 tons.

Heavy cruisers

The heavy cruiser was defined in the London Naval Treaty of 1930 as a cruiser with a main gun calibre not exceeding 8 inches. The earlier Hawkins class were therefore retrospectively classified as such, although they had been initially built as "improved light cruisers".

Large light cruisers

The "large light cruisers" were a pet project of Admiral Fisher to operate in shallow Baltic Sea waters and they are often classed as a form of battlecruiser.
