How Britain viewed the American naval buildup

Was the Royal Navy seriously worried about the United States Navy's postwar buildup?

It watched the programme closely but was not panicked, because Britain already possessed many 15-inch-gunned capital ships and saw the American ships as the next competitive generation.

American construction belonged to an existing qualitative competition, rather than arriving as a sudden strategic shock. British planners watched the programme closely. They could still compare the new American 16-inch ships with their own mature generation of 15-inch capital ships. Observation and concern did not require panic or an immediate one-for-one response.
