T 47-class destroyer

The T 47 class (or Surcouf class) were the first destroyers built for the French Navy after the Second World War. Twelve ships were built between 1955 and 1957. The ships were modernised in the 1960s and decommissioned in the 1980s, when they were replaced by the Georges Leygues-class frigates.

These ships were larger than other contemporary European destroyers and were based on the wartime, but were enlarged and had a dual purpose armament. The ships were designed as Squadron escorts (Escorteur d'escadre) rather than for independent operations, therefore they had a slower speed than their predecessors. The main guns were the French designed Model 1948 127 mm/54 gun, which enabled them to use the same 5-inch shells as the U.S. Mark 18 gun. The secondary armament was composed of 57mm/60 modèle 1951 guns.

Modifications
During the 1960s the entire class were modernised and modified as either flotilla flagships, anti-aircraft guided missile or anti-submarine destroyers.

Flagships
Three ships — Surcouf, Cassard, and Chevalier Paul — were converted into flotilla flagships (conducteurs de flottilles) between 1960 and 1962. One 57 mm gun turret, two triple torpedo launchers and two 20 mm guns were removed in order to enlarge the superstructure to accommodate an admiral, his staff, and additional communications equipment.
