How Admiralty offices divided responsibility for naval guns

Naval Ordnance managed the weapon, while Naval Construction controlled what turret ring and gun arrangement the ship could actually accept, leaving senior Admiralty politics to arbitrate priorities.

Question

Who actually decided which naval guns and turrets went onto a Royal Navy ship?

Short answer

Naval Ordnance controlled the gun, but Naval Construction controlled its integration into the hull, with senior Admiralty leadership resolving the resulting institutional choices.

Notes

Responsibility for the gun itself was separate from responsibility for integrating it into a warship. The Director of Naval Ordnance handled the weapon, while the Director of Naval Construction decided what turret ring and gun fit the hull would be designed around. Those offices could sit under different Sea Lords, turning a technical interface into an internal Admiralty political issue. Stronger intervention by Reginald Henderson might also have prevented the British 4.5-inch programme from pausing as much as it did in 1939.
