Dreadnoughts from Around the World (1905-14): 1909 January-June

Neptune's aft superfiring pair improved stern fire, while the retained wing turrets limited the broadside to eight guns and left only two firing forward.

Neptune spreads heavier protection across more of the hull, replaces three-pounders with four-inch secondary guns, and reaches 21 knots with 25,000 shaft horsepower.

The interval between Neptune and the Colossus class shows commissioning trials, exercises, and war games feeding practical experience into rapid British design changes.

The Royal Navy ordered HMS Indefatigable after operating the Invincible class for months, making her an evolved second-generation battlecruiser rather than an isolated experiment.

Indefatigable's speed is placed within a worldwide British strategy in which battlecruisers pursue economic warfare while the battle fleet controls blockades and choke points.

The Florida class combines long-range machinery choices with ten centerline 12-inch guns, improving firing arcs while retaining a troublesome same-level after pair.

The familiar Anglo-German construction race is contrasted with a more innovative Anglo-American contest over dreadnought layout and fighting efficiency.

Japan's Kawachi class had 12-inch guns throughout, but different barrel lengths undermined the uniform ballistic performance expected of an all-big-gun battleship.

Italy's adoption of the triple turret shows how a navy expecting fewer hulls could raise each ship's hitting power by concentrating more guns on the centerline.

Dante Alighieri combines four triple turrets with 32,000 shaft horsepower and a 22-knot speed, applying Vittorio Cuniberti's ideas to an unusually fast battleship.

Italy's confined Mediterranean requirements and limited fleet budget made a fast battleship more useful than maintaining separate battleship and battlecruiser forces.

Four centerline triple turrets give Dante Alighieri a twelve-gun broadside without wing-turret blast striking the ship's deck or superstructure.

The Gangut class follows the Italian centerline pattern with four triple turrets, high trial power, and a 24.1-knot performance that blurred battleship and battlecruiser categories.

The series counts a warship as under construction only after laying down and as in service only after commissioning, separating orders from physical and operational reality.
