The Royal Navy's transition from DC to AC

A technology answer places the Royal Navy's AC conversion in a gradual postwar fleet transition.

Daring Class Destroyers (1949)Postwar Naval Technology Royal Navy Ship Electrical Systems

Question

When did Royal Navy ships change from direct current to alternating current electrical systems?

Short answer

The transition was phased through the 1950s and 1960s, with the Daring-class destroyers helping test the new approach while older DC ships remained in service.

Notes

The fleet could not change electrical standards all at once because old and new ships served together. The Daring class formed part of the experimentation, while the broader transition continued into the 1960s.
