Shipbuilding trends of the 1880s-1950s: Long Patrol Part 7/11 The Roaring Twenties

The Washington Treaty left Britain room to trade armour for speed, making a fast battlecruiser a plausible alternative to HMS Nelson.

A Trafalgar-style image of the battle line did not match the movement and position-seeking that shaped most of Jutland.

Converting Admiral-class hulls into fast carriers could have given Britain a globally deployable task force with its battlecruisers.

Memory of the British battlecruiser losses at Jutland shaped what Britain could build, and even what it could call a battlecruiser, during the 1920s.

Britain kept Hood and gained two new 16-inch battleships, while the United States gained formal equality that Congress was slow to fund.

Nelson's all-forward main battery saved weight under treaty limits but created awkward firing restrictions and reflected the politics of the post-Jutland period.

The Italian Turbine class carried First World War torpedo-boat assumptions into a Mediterranean conflict increasingly shaped by aircraft and escort work.

Seven of the eight Turbine-class ships were lost to aircraft or aircraft-laid mines, exposing their limited margin for adaptation.

The Turbine class had too little margin for stronger anti-aircraft defences and broader escort duties.

Royal Navy experience pointed toward distributed war, while Japanese and American doctrine still emphasized decisive fleet concentration before the Second World War.

Henderson's authority as Third Sea Lord allowed distributed-war thinking to influence procurement before the Second World War.

Smaller naval establishments can give a tightly aligned group more influence, encouraging ships optimized for one doctrine rather than many duties.
