FRENCH FRIGATES DESIGNED FOR STEALTH

The article describes F 711 SURCOUF, the latest frigate delivered to the French Navy. This is the second of a class of six 3600t 'Fregates type la Fayette' being built at Lorient Naval Dockyard over the next few years. The lead ship F 710 LA FAYETTE was commissioned last year. The most striking feature of SURCOUF is her streamlined profile afforded by her covered working decks and smooth contoured superstructure. To achieve stealth, every detail of hull, superstructure and mast has been designed to reduce radar cross section (RCS) ie inclined bulwarks and hull sides, solid masts with inclined sides, streamlined gun turret, elimination of all right angles and concealment of ship's boats behind flush mesh curtains. RCS is claimed to be no greater than that of a patrol boat, while IR signature is reduced by special paints, insulation in hot areas and the use of grp for exhaust funnels. Acoustic signature is curtailed by installing machinery in cradles on flexible mounts.
