Why the Naval Defence Act was a political break

The Naval Defence Act emerged from substantial political argument, and the service lives of its ships provide only one measure of its importance. Dreadnoughts, aircraft carriers, submarines, and changing destroyer roles would transform fleets within decades. Technological obsolescence is therefore only part of the assessment. The episode also asks whether the act changed how Britain organized naval power and prepared for later developments. This opening frames naval legislation in terms of the institutions and capacity it creates as well as the ships it buys.
