Shipbuilding trends of the 1880s-1950s: Long Patrol Part 2/11 1890s Battleships

The episode sets French Charlemagne-class ships beside Sweden's Oden class to examine two sharply different answers to late-19th-century naval defence.

Charlemagne's flared hull, 12-inch guns, secondary battery, and torpedo tubes show both the firepower and the design compromises of an early French pre-dreadnought.

The completion dates of Charlemagne, Saint Louis, and Gaulois expose how French shipbuilding could be both slow to start and unexpectedly quick to finish.

Sweden's Oden class concentrates enough guns in a 3,445-ton coastal ship to make an attacker commit much larger and costlier vessels.

France and Sweden both use flotilla-defence logic, but France keeps building ocean-going battleships as insurance against the limits of that theory.

Oden's secondary battery gives it a real answer to torpedo boats, while its 10-inch guns reveal the compromises inside compact coastal battleship design.

Backed by forts and flotillas, several compact coastal ships can force an attacker to commit a much larger battle fleet simply to threaten the coast.

The video distinguishes a defensive risk fleet, meant to deter Britain, from Germany's offensive battle fleet with colonial and long-range ambitions.

A short-range German battle fleet directed at France, backed by long-range cruisers, might have looked less threatening to Britain and altered diplomatic pressure.

The video closes by linking these coastal-defence ships and their successors to the Russian naval expansion later destroyed at Tsushima.
