4th Destroyer Squadron (United Kingdom)

The 4th Destroyer Squadron was a naval unit of the Royal Navy from 1951 to 1959.

Overview
After World War II, the British Navy reverted to its previous layout and command structure in 1950 the 4th Destroyer Flotilla of the Home Fleet was disbanded and succeeded by the 4th Destroyer Squadron. The Admiralty controlled global deployment of the navy until 1964 when that department was abolished and replaced by the new Navy Department, Ministry of Defence. These geographic commands usually comprised fleets, squadrons, flotillas, and single ships. In 1954, major re-structuring of the composition of the navy was undertaken, leading to downsizing and warships being rotated between the various fleets and stations. In 1954 and 1971, many of these commands were abolished or amalgamated into larger geographic commands. In November 1971, nearly all British naval forces were brought under the command of a single fleet whose headquarters was at Northwood, Middlesex then under the control of Commander-in-Chief Fleet. In 2012, that post was abolished and replaced by the Fleet Commander who now operated from Navy Command Headquarters in Portsmouth, Hampshire.

Organizational changes
Note: Command structure organizational changes took place within Royal Navy post war period the term Flotilla was previously applied to a tactical unit until 1951 which led to the creation of three specific Flag Officers, Flotillas responsible for the Eastern, Home and Mediterranean fleets the existing destroyer flotillas were re-organized now as administrative squadrons.
