Some More Battle Cruisers

The battlecruiser began as a cruiser powerful enough to destroy weaker opponents and fast enough to avoid battleships, but fleet scouting soon made it the capital ship most likely to fight.

The same speed-armour-firepower triangle produces different battlecruisers when a navy needs fleet reinforcement rather than independent economic warfare.

Contemporary battleship-calibre armament separates battlecruisers from large cruisers, while sacrificing speed for protection can move a design toward a battleship.

Cruiser-style internal subdivision saves hull weight and improves power-to-weight ratio, but it gives a battlecruiser less damage-limiting compartmentation than a battleship.

Hood's 15-inch guns, 32-knot speed, protection, and cruiser-style internal construction provide the built standard against which the uncompleted designs can be judged.

The Admiral class shows the Royal Navy using wartime construction to preserve a major capability before the familiar postwar cycle of cuts and political resistance.

Because the Royal Navy tracked Germany's coal and imports through the blockade, it could judge whether projected capital-ship construction was industrially credible.

A range of about 7,500 nautical miles at 14 knots identifies Hood as a ship for global deployment rather than a capital ship optimized only for the North Sea.

The submarine war pushed destroyers and merchant ships ahead of three Admiral-class hulls, but pressure from Beatty and Jellicoe kept one battlecruiser in construction.

Russia's Borodino-class design combines twelve 14-inch guns and substantial protection with too little speed margin over contemporary fast battleships.

The Mackensen class offers excellent range but a conservative mix of 28-knot speed and 13.8-inch guns as rivals move to 15-inch weapons.

Ersatz Yorck's 15-inch guns and lower speed move the German design toward a fast battleship better suited to contesting sea control.

The hypothetical favors more Scharnhorst and Gneisenau type ships with 15-inch guns over Bismarck and Tirpitz, using modest armour or calibre savings to create a more useful German fast battleship.

The Amagi class combines ten 16-inch guns, long range, and strong machinery, but its torpedo battery consumes weight and creates vulnerable internal spaces.

Turbo-electric transmission, a raised after turret, and a flexible secondary battery show the Lexington design combining high power with practical attention to operations and future refits.

A 33-knot speed, 10,000-nautical-mile range, and eight 16-inch guns could have made the Lexington battlecruisers unusually effective fast-response ships in an Atlantic or Pacific war.

The Washington treaty removed several promising battlecruiser designs, while the type's long, fast hulls made Lexington and Amagi-class ships natural candidates for aircraft-carrier conversion.

Compressed game maps favor direct gun battles and conceal the geographic room a Lexington-type battlecruiser needs to exploit speed, range, and fast-response missions.

The G3 design combines about 54,800 tons at deep load, 160,000 shaft horsepower, 31-32 knots, and nine 16-inch guns, giving up some Lexington speed for another main gun.

The G3 design concentrates nine 16-inch guns forward, saving weight but leaving a stern chase without direct main-battery fire.

A converted Admiral-class hull would probably have used a full-length flight deck and large hangar to support the Royal Navy's developing strike-carrier role.

Royal Navy expectations of fast, dispersed actions like Dogger Bank or the Falklands made G3's uncovered stern more serious and support its classification as an economy-constrained battlecruiser.
