The Royal Navy's resources in the 1920s and 1930s gave it room to reconsider weapon programs instead of accepting the first workable standard. When a new design appeared to balance anti-aircraft and anti-surface needs better, the service could redirect investment toward it. That freedom encouraged experimentation but also prolonged the period in which several calibers and mounts competed for adoption. The continued life of the 4.7-inch gun therefore reflected an unsettled replacement process as much as confidence in the existing weapon.

How abundant funding could delay gun standardization
The interwar Royal Navy could afford to abandon one promising dual-purpose gun and pursue another as its requirements changed.
