Invincible class

The Invincible-class ships were the first battlecruisersThese ships were formally known as armoured cruisers until 1911, when they were re-designated as battlecruisers by an Admiralty order of 24 November 1911. Unofficially a number of designations were used until then, including cruiser-battleship, dreadnought cruiser, and battle-cruiser. See Roberts, pp. 24–25 in the world.

Indefatigable class

The design of the Indefatigable class represented a modest reworking of the preceding , featuring increased endurance and an improved cross-deck arc of fire for their midships wing turrets achieved by lengthening the hull. Like its predecessor, the design resembled the contemporary dreadnought, but sacrificed armour protection and one turret from the main battery for a 4-knot speed advantage. Originally was the only ship of the class, but and were later built as part of a scheme to improve the defense of the Dominions by having each Dominion purchase a "fleet unit" of one battlecruiser, three light cruisers, and six destroyers. New Zealand agreed to fund one battlecruiser and chose a modified Indefatigable design rather than the then being built for the Royal Navy.

They spent most of the war patrolling the North Sea and participated in most of the battles there.
Of the three, only New Zealand was in the United Kingdom when the war began. Indefatigable was in the Mediterranean, where she unsuccessfully pursued the German warships and as they sailed towards Turkey

Lion class

The Lion class, nicknamed the "Splendid Cats", were a significant improvement over their predecessors of the in speed, armament, and armour. The Lion-class ships were 2 knots faster, exchanged the 12 inches (30 cm) guns of the older ships for 13.5 inches (34 cm) guns, and had a waterline belt

HMS Queen Mary

HMS Queen Mary was similar to the s, though she was slightly larger and given more powerful engines to achieve the same speed as the earlier ships. Her secondary guns were better protected and some of her belt armour was redistributed. She was the last battlecruiser completed before the beginning of the war, and she participated in the Battle of Heligoland Bight shortly after the war began. As part of the 1st Battlecruiser Squadron, she unsuccessfully attempted to intercept a German force that bombarded the North Sea coast of England in December 1914. She was refitting during the Battle of Dogger Bank in early 1915, but participated in the next major fleet action of the war, the Battle of Jutland in mid-1916. Queen Mary hit the German battlecruiser early in the battle and burnt out one of that ship's rear turrets. Seydlitz later knocked out one of Queen Marys main guns. The German battlecruiser , in the meantime, had lost sight of her previous target in the haze and switched to Queen Mary. Within 10 minutes, Queen Mary was hit twice, exploding shortly afterwards.

HMS Tiger was the most heavily armoured battlecruiser of the Royal Navy at the start of the First World War, although she was still being finished when the war began.

Tiger was the oldest battlecruiser retained by the Royal Navy after the tonnage limits of the Washington Naval Treaty came into effect in 1922. She became a gunnery training ship in 1924 and joined the Battlecruiser Squadron in 1929 while its flagship, , underwent a lengthy refit.

The class was going to consist of , Anson, Howe, and Rodney—all names of famous Admirals—but the latter three ships were suspended as the material and labour required to complete them was needed for higher-priority merchantmen and escort vessels. Their designs were updated to incorporate the lessons from the Battle of Jutland, but the Admiralty eventually decided that it was better to begin again with a clean-slate design so they were cancelled in 1919.

G3 Battlecruiser

The G3 battlecruisers were planned as a response to naval expansion programmes by the United States and Japan. The four ships of this class would have been larger, faster, and more heavily armed than any existing battleship (although several projected foreign ships would be larger). The "battlecruiser" designation came from their higher speed and lesser firepower and armour relative to the planned N3-class battleship

 design. The G3s carried nine 16 inches (406.4 mm) guns and were expected to achieve 32 knots, while the N3s would carry nine 18 inches (457.2 mm) guns on the same displacement at the expense of a slower speed. While officially referred to as "battlecruisers", the G3s have also been considered "fast battleship

The term is especially appropriate when applied to a design which was not only faster than the preceding battleship class, but faster than subsequent classes...

The G3 design was approved by the Board of Admiralty on 12 August 1921. Orders were placed in October and November, but were suspended later in November with the beginning of the Washington Naval Conference
