How successful automatic six-inch guns could reshape the postwar Royal Navy

Money and early technical performance limited automatic six-inch conversions, but a successful program could have created a long-lived British gun family.

Question

Why were Edinburgh-class cruisers not rebuilt with Tiger-class automatic six-inch guns?

Short answer

The money was scarce and the mount did not mature quickly enough; early success could have justified conversions and a much broader Royal Navy gun lineage.

Notes

Rearming older cruisers with Tiger-class automatic six-inch turrets depended on scarce postwar money and a weapon that worked reliably soon enough to justify the expense. Early technical success could have supported more conversions and a larger production run. In the imagined continuation, the twin mounting then becomes an option for County-class destroyers, Bristol, and Type 42. A six-inch shell offers room for sensors or other adaptations while retaining an explosive payload. Retaining that main battery could also encourage a three-inch secondary battery. The Falklands comparison considers the additional gunfire such ships could put in front of aircraft or incoming missiles, as a hypothetical armament path.
