Argo was a French Navy Redoutable-class submarine of the M6 series commissioned in 1933. She participated in World War II, first on the side of the Allies from 1939 to June 1940, then in the navy of Vichy France until November 1942, and finally in the Free French Naval Forces through the end of the war. Along with Archimède, Casabianca, Le Centaure, and Le Glorieux, she was one of only five out of the 31 Redoutable-class submarines to survive the war.

Characteristics

Profile of Casabianca, sister ship of Argo.

Argo was part of a fairly homogeneous series of 31 deep-sea patrol submarines also called "1,500-tonners" because of their displacement. All entered service between 1931 and 1939.

The Redoutable-class submarines were 92.3 metres (302 ft 10 in) long and 8.1 metres (26 ft 7 in) in

draft of 4.4 metres (14 ft 5 in). They could dive to a depth of 80 metres (262 ft). They displaced 1,572 tonnes (1,547 long tons) on the surface and 2,082 tonnes (2,049 long tons) underwater. Propelled on the surface by two diesel engines producing a combined 6,000 horsepower (4,474 kW), they had a maximum speed of 18.6 knots (34.4 km/h; 21.4 mph). When submerged, their two electric motors
produced a combined 2,250 horsepower (1,678 kW) and allowed them to reach 10 knots (19 km/h; 12 mph). Also called "deep-cruising submarines", their range on the surface was 10,000 nautical miles (19,000 km; 12,000 mi) at 10 knots (19 km/h; 12 mph). Underwater, they could travel 100 nautical miles (190 km; 120 mi) at 5 knots (9.3 km/h; 5.8 mph).

Construction and commissioning

Laid down at Chantiers Dubigeon in Nantes, France, on 25 August 1927[2] with the hull number Q151, Argo was launched on 11 April 1929.[2] She was commissioned on 12 February 1933.[2]

Service history

World War II

French Navy

At the start of World War II in September 1939, Argo was assigned to the 4th Submarine Division based in Brest, France.[3] Her sister ships Henri Poincaré, Le Centaure, and Pascal made up the rest of the division.[3][4]

German ground forces advanced into France on 10 May 1940, beginning the

Italy declared war on France on 10 June 1940 and joined the invasion. On 25 June 1940, the Battle of France ended in France's defeat and an armistice
with Germany and Italy that went into effect that day.

Vichy France

After the French surrender, Argo served in the naval forces of

hull damage that kept her out of service for several weeks while undergoing repairs.[3]

In August 1942, Argo transferred to French West Africa, departing Casablanca on 10 August 1942[3] in company with Le Centaure and their sister ship Archimède and arriving on 16 August 1942 at Dakar in Senegal,[3] where the three submarines formed the 3rd Submarine Division.[3][7] By 9 November 1942, she was part of the French West Africa Submarine Group.[3]

Free French Naval Forces

antisubmarine warfare training for British warships, serving as training targets.[3]

In September 1943 Argo was detached to the

Key West, Florida.[3][9] Although far from the combat zone, sound-school operations were very wearing on the French crews and their equipment, requiring the submarines to operate at sea 23 days per month[3] as training targets.[9] Argo collided with the U.S. Navy Tacoma-class frigate USS Huron (PF-19) off Key West on 28 April 1945, suffering damage to both of her periscopes.[9]

After Germany surrendered on 8 May 1945, the need for antisubmarine warfare training in the Atlantic dropped sharply, and French submarines operating at U.S. Navy sound schools were soon returned to French operational control.[9] They departed U.S. ports for bases in French North Africa in July 1945.[9] World War II ended with the surrender of Japan on 2 September 1945, and Argo was disarmed on 26 April 1946.[10]
