The T 53 class were the second group of destroyers built for the French Navy after World War II. These ships were a modified version of the T 47-class destroyers. The main difference with the preceding ships was the provision of improved air warning and tracking radars as well as an anti-submarine mortar. The ships were built between 1957 and 1958 and were decommissioned in the late 1970s or early 1980s. A single modified ship La Galissonnière was built as a trials ship for a new generation of French weapons. This ship was designated as the T 56 class.

Modifications

In 1972–73 two of the class were substantially modified:

• Duperré was completely rearmed with a Model 1968 100 mm (4 in) main gun, four Exocet MM38 missiles, two quadruple L5 torpedo launchers, and two 20 mm AA cannon. She was also fitted with a helipad to carry a Lynx WG13 helicopter.^[1]
• Forbin had her forward 57 mm turret removed, and her aft 127 mm turret was replaced by a helipad. She was then principally used as a naval aviation training ship alongside the helicopter cruiser Jeanne d'Arc.^[2]

La Galissonnière

La Galissonnière differed slightly in specification from the rest of the class as she was built specifically to test the Malafon anti-submarine missile.^[3]
