French dreadnought design met the limits of its shipyards
Courbet and Bretagne arrived behind their design generation, while short-range doctrine, restricted yards, and army commitments constrained their successors.

Normandie and Lyon stretched France's investment in 340 mm guns
Restricted yards and a short production run encouraged France to retain 340 mm guns, first in twelve-gun Normandie and then in sixteen-gun Lyon.

Vanguard and F3 expose competing definitions of fast battleship

F3's forward battery and speed change two German encounters
Two encounters with Scharnhorst and Gneisenau test how F3's nine forward-firing guns and higher speed could affect pursuit and combat.

Samuel B. Roberts combined a lighter displacement with a capable hull
The proposed explanation for Roberts' extra speed combines a hull designed for a heavier ship with reduced displacement and heavily driven machinery.

Rodney's trials and hull lineage challenge a fixed speed ceiling
Rodney's trial performance and the hull research behind F3 support the argument that published speed left an emergency reserve.

Sloop movements and aerial identification suggest unused speed
A sloop keeping station with a cruiser and Johnnie Walker's formation being mistaken for cruisers provide two arguments for looking beyond rated speed.
