The Chamois class were French minesweeping sloops (Avisos dragueur de mines) ordered between 1935 and 1939. They were similar in design to the Elan class, and like them classed as minesweepers, but were actually used as anti-submarine ships, convoy escorts and patrol vessels.

Although all 24 ships of the class were laid down between 1936 and 1939, only five were commissioned in time to serve in the French Navy during World War II. Of the remaining ships, four were completed by the Germans, of which three where commissioned, twelve were scrapped incomplete, and three were eventually completed after the war and served in the French Navy into the 1960s.^[3]

Design and armaments

The 647 tonne ships were 78.30 metres (257 ft) long overall, 8.70 metres (28 ft 7 in) in the beam, and had a draught of 3.28 metres (10 ft 9 in). They were powered by two Sulzer diesel engines, delivering 4,600 hp (3,430 kW) to two shafts, which gave a top speed of 20 knots (37 km/h; 23 mph). The 105 tonne fuel capacity gave them a maximum range of 10,000 nautical miles (19,000 km; 12,000 mi) at 9 knots (17 km/h; 10 mph). The ship's complement was 88 in peacetime, but 106 during the war.^[4]

The ships were originally designed to be armed with twin Model 1933 100 mm (3.9 in)/45 DP guns, one quadruple and two twin Hotchkiss 13.2 mm AA machine guns, and minesweeping gear. In fact the five ships completed before the outbreak of the war (Annamite, Chamois, Chevreuil, Gazelle and Surprise) were fitted with either a Model 1892 or a Model 1932 100 mm (3.9 in)/45 gun or twin Model 1926 90 mm (3.5 in)/50 guns, the machine guns as designed, two depth charge projectors and racks.^[3]

The three vessels that survived the war (Annamite, Chevreuil, Gazelle) were rearmed in 1948 and received twin Model 1926 90 mm/50 guns, a single 40 mm/60 Mk.3 gun and six single 20 mm/70 Mk.2 guns, two depth charge projectors and racks. The ships that were completed about the same time (Bisson, Cdt Amyot d'Inville, Cdt de Pimodan) were fitted with twin 105 mm (4.1 in)/45 SK C/32 guns, but were otherwise the same.^[3]

The three ships that were commissioned by the Germans during the war were fitted with German armaments. All received two single 105 mm (4.1 in) SK C/32 guns, a twin 37 mm (1.5 in)/83 SK C/30 AA gun, and a quadruple 20 mm/65 C/38 AA gun. Two ships (SG14 and SG15) were armed with a further ten single C/38 guns, while the SG21 had two twin and six single guns of the same type.^[5]
