Why the Queen Elizabeth class raised the stakes

The Queen Elizabeth class formed part of a wider international contest involving Britain, the United States, Italy, Japan, France, Russia, Germany, and South American powers. Its 15-inch guns and intended speed leapfrogged the 14-inch designs appearing abroad and forced rivals to consider another expensive step in size and infrastructure. For Germany, that qualitative escalation reinforced a quantitative problem because matching Britain's ships could not erase Britain's numerical lead. Geography made the Anglo-German race especially threatening to Britain, since the Royal Navy sat across Germany's access to the wider world. The same technical competition had different strategic meanings for geographically distant powers such as the United States.
