When Royal Navy ships gained air conditioning

When did the Royal Navy begin installing air conditioning in its ships?

Ventilation experiments began in the interwar decades, limited air-conditioning installations appeared from about the 1960s, and adoption widened after the First Gulf War.

Fans and ventilation trials in the 1920s and 1930s did not amount to fleet-wide air conditioning. Recognizable early installations appeared around the 1960s but remained limited or experimental. Broad adoption followed the operational lessons of hot-weather deployments around the 1991 Gulf War.
