Roosevelt points to the 1815 Navy List as evidence that the war produced revolutionary new weapons. The period's 'torpedoes' were stationary mines, and their demonstrated effect was mainly to make British ships cautious around some anchorages. Fulton combined steam propulsion, a protected central paddle wheel, thick sides, and pivot guns, leading Roosevelt to call her a prototype ironclad. That label stretches the resemblance, while the claim of an immediate transformation in American power sits uneasily with Congress allowing much of the fleet to decline. The comparison separates technological ancestry from a sustained operational revolution.

Mines, Fulton, and claims of an American naval revolution
Roosevelt treats early mines and the steam warship Fulton as anticipations of later naval technology; their immediate effects and the fleet's subsequent decline complicate that claim.
