The classe T 47 constitutes the first series of squadron escorts ^{[ first ]} of the French Navy. They were, with rapid escorters and coastal escorters, among the first surface buildings built in France after the Second World War.
Following “T 47” , was built a series of five designated squadron escorts “T 53” , similar general characteristics but specially developed for the conduct of air actions ^{[ 2 ]} . Endowed more efficient air detection for this purpose, they could play the role of “Piquet Radar” for the lighting of a naval force.

The Overcouf (D621) and 1970.

Twelve ships were built between 1955 and 1957. This class was derived from the Mogador class counter-hearters entered service in 1939-1940.

The armament of the “T 47” was versatile, both anti-ship, anti-aircraft and anti-sous-marine. They were designed to serve essentially as the escort of a naval force including an aircraft carrier, hence this new name of squadron escort more in accordance with their mission, than that of counter-hearters.

The ships were modernized in the 1960s. They were disarmed in the 1980s to be replaced by the anti-submarine frigates Class Georges Leygues and Anti-Aerian Cassard class.

Flottilles conductive buildings: (CDF)

• Three units ( Overcouf , Cassard , Knight Paul ) were fitted into flotilla drivers between 1960 and 1962. The transformations mainly focused on an enlargement of the rear roof and the gateway block, in order to house a admiral, its police staff and its means of command on board (PC operations and “gateway Admiral “with a glass shelter). To this end, the before 57 lookout mm And the two 550 long-term light launcher tubes platforms mm , placed at the rear, were landed.
  Armament then consisted of:
  • 3 double 127 mm frame turrets
  • 2 double sides of 57 mm frame
  • 2 20 mm guns
  • 2 triple platforms of 550 mm ASM Tobe Tobes

Missile launcher buildings: (BLM)

The Bouvet (D624) Refused “Tartar” in 1965.

• Four units ( Bouvet , Kersaint , Dupet-Thouars , Du tent ) were overwhelmed between 1961 and 1965 to become Mer-Air missile launcher buildings.
  In July 1958 , United States ^{[ 3 ]} Offer France to provide free of charge the RIM-24 Tartar weapon system (missiles, launch ramp, shooting and three-dimensional radar). The redesign of the building and the maintenance of the weapon system remaining the responsibility of the beneficiary country. In April 1959 , the French Navy responds favorably to this offer and requests these conditions the delivery of four tartar weapon systems for 4 T47B, at the rate of one per year, from the summer of 1961.
  In July 1959 , the American organization M.A.A.G. indicates that the first system will be delivered during the second half of 1961, and specifies that the receiving building must be ” Earmarked for NATO Command “, which the French government accepts without reservation. But in November 1959 The M.A.A.G. reports that US military aid to allies is restricted and that consequently the delivery of the last three systems will no longer be free. Indeed, only the first weapon system, installed on the Dupet-Thouars will be offered by the United States. ^{[ 4 ]} .
  After this overhaul Tartar Their crews were reduced to 277 men and their armament was:
  • 1 single tartar mk13 ramp (40 succule missiles)
  • 3 57 mm double hindsters
  • 1 ASM 375 mm ASM rocket launcher
  • 2 triple platforms of 550 mm ASM Tobe Tobes

The anti-underwater buildings: (FAIRY TALE)

• Five units ( Estrées , Mesh , Vauquelin , Casabianca , Guépratte ) were overwhelmed from December 1965 (D’Estrés) to become operational again in January 1971 (Guépratte) as anti-submarine control buildings. They were the first buildings of the French Navy to embark a towred sonar with variable immersion to detect sub -sailors. After this overhaul Malafon Their armament was:
