Argonaute-class submarine

The Argonaute class were a sub-class of the 600 Series submarines built for the French Navy prior to World War II. There were five vessels in the class, built to a Schneider-Laubeuf design by Schneider-Creusot. They were ordered in 1927 and completed by 1935.

Development

The Argonaute class, though designated as Class 2 coastal submarines, were built for service in the Mediterranean. Ordered in 1927 and completed in 1935, they were built to conform to the interwar naval treaties arising from the 1922 Washington and 1930 London conferences, which placed restrictions on the number and size of warships of various types that nations could build.[3] The coastal submarine was limited to a 600-ton surface displacement, though there was no limit placed on the numbers of these vessels that could be built.

General characteristics

The Argonaute class were 63.4 m (208 ft) long, and displaced 630 tonnes surfaced and 798 tonnes submerged. They had a range of 4,000 nautical miles at 10 knots, with a maximum surface speed of 14 knots, and a submerged speed of 9 knots. Their armament consisted of eight torpedo tubes; six 550 mm (22 in) and two 400 mm (16 in), a 75 mm (3 in)/35 M1928 deck gun and a single 8 mm/80 machine gun. They carried a crew of 41 men.

Service history

During World War II the submarines were based in French North Africa. On 8 November 1942 during "Operation Torch" Argonaute was sunk off Oran by the British destroyers Achates and Westcott.[4] The remaining four boats joined the Free French Naval Forces in December 1942. Aréthuse, Atalante and La Vestale were laid up in reserve in 1944, and all four were eventually sold for scrap in 1946.[1]
