They were an immediate follow-on from the earlier Le Corse-class (or E50 type) frigates, and like them, were long-range convoy escorts capable of high speed.
[2] The first seven ships, paid for by the United States under the Mutual Defense Assistance Act were ordered in 1952.
[3] The E52 type shared a flush-decked layout with the E50 class, and had a similar armament of three twin 57 mm turrets) (one forward and two aft) and an anti-submarine armament consisting of a battery of heavyweight guided torpedoes and a 375 mm Bofors six-barrel rocket launcher.
The major difference was the layout of the armament, with the torpedo tubes moving from forwards to amidships, and the Bofors launcher moving from amidships to forward of the bow gun, thus reducing topweight and improving the arc of fire for the Bofors launcher.
[3] Two more of this type were ordered in 1957, but were cancelled owing to financial problems.
