Design and description
The Georges Leygues-class ships were designed as anti-submarine (ASW) escorts for the fleet.Template:Sfn They had an overall length of Template:Convert, a beam of Template:Cvt and a draught of Template:Cvt. The ships had a standard displacement of Template:Convert and Template:Convert at full load. The Georges Leyguess' propulsion machinery used a CODOG configuration with one SEMT-Pielstick 16PA6-V280 diesel engine and a Rolls-Royce Olympus TM3B gas turbine were coupled to each of the two propeller shafts. The diesels were used for speeds under Template:Convert and the gas turbines for sprints up to Template:Convert. The diesels were rated at a total of Template:Convert and the turbines at a total of Template:Cvt.Template:Sfn The combination give the ships a range of Template:Convert at Template:Convert. The frigates had a complement of 216 sailors.Template:Sfn
The primary anti-ship weapon of the Georges Leyguess consisted of four single box launchers for MM40 Exocet anti-ship missiles, located aft of the funnel with two launchers on each broadside. The frigates were designed with a single [[French 100 mm naval gun|Template:Convert Modèle 1968]] dual-purpose gun in a single-gun turret forward of the superstructure. They were also equipped with two Template:Cvt guns. The ships were fitted with a octuple Crotale anti-aircraft missile launcher with 26 reloads located on the aft superstructure. The anti-submarine| (ASW) weapons of the Georges Leygues-class ships consisted of two torpedo launchers , one on each side of the ship. Each ship carried ten torpedoes.
