The Royal Navy's Forgotten Lost Battleship Generation: Key Ship Series 8 - Ships 6

Uncertainty over the naval treaty system prompted the Royal Navy to study a largely forgotten generation of capital ships before 1930, including designs whose surviving record may be incomplete.

Pressure for cheaper battleships came especially from political leaders, while naval constructors and admirals still had to produce ships capable of surviving against existing heavily armed opponents.

Royal Navy constructors kept cruiser, carrier, capital-ship, destroyer, and modernization studies active even without an immediate building program, preserving skills and shortening emergency response times.

Two 1927 studies paired fourteen-inch guns with compact hulls and reduced protection, creating cheaper ships that look like a dangerous baseline rather than convincing successors to Nelson and Rodney.

Surviving drawings show sixteen-inch concepts without their statistical tables, illustrating how incomplete archives complicate efforts to reconstruct the Royal Navy's interwar capital-ship thinking.

The 35,000-ton 16A design combined eight sixteen-inch guns in four twin turrets with twenty-three-knot speed, sacrificing one gun to reduce the firepower lost when a turret was disabled.

The 14A and 14B studies cut displacement and armor while sharply increasing machinery power, suggesting a faster battleship whose exact speed is absent from the surviving table.

Studies armed with twelve-, eleven-, or ten-inch guns could satisfy ambitions for tighter treaty limits, but their thin armor and inability to escape ships such as Nagato made them dangerous unless every existing heavy capital ship disappeared.

The difficulty of defining and banning bombers shows why interwar arms-control agreements became blunt instruments, a problem that helps explain the compromises and loopholes surrounding naval treaties.

British intelligence knew the United States and Japan would resist the smallest treaty limits, supporting the interpretation that many surviving studies demonstrated political compliance rather than the fleet's preferred warship.

The 1928 Design 12L paired nine twelve-inch guns with 80,000 shaft horsepower and twenty-seven-knot speed, showing that the reduced treaty studies could still supply the hull and machinery basis for a faster fallback.

Later ships such as Bismarck, Tirpitz, and Yamato provide a counterfactual stress test showing how rapidly Britain's small treaty battleships would become untenable if other powers resumed heavy construction.

Repeated interwar studies trained British design teams and tested layouts that fed into later capital ships, while countries with interrupted design institutions paid a human as well as industrial cost.

Even without treaty limits, dockyards and global basing would constrain a Royal Navy battleship to a practical fast design of roughly 45,000 to 50,000 tons with sixteen-inch guns.

The Royal Navy maintained everyday global presence with cruisers while relying on overseas bases and support infrastructure to concentrate its battle fleet wherever a major war required it.

Admiral Chatfield hoped twelve fourteen-inch guns would match the weight of fire of nine sixteen-inch weapons, but the difficulty of quadruple turrets strengthens the case for a preferred British design with nine sixteen-inch guns.

If no London settlement extended the treaty system, British politicians might still hold the first new battleships near the old 35,000-ton limit in hope that other navies reciprocated, before foreign escalation forced larger construction.

Royal Navy experiments tracked shells after water entry to guide underwater armor, subdivision, and gunnery range choices, but any apparent safe zone also benefited the opponent.
