Ship project history: Built under "small program" of 1924. Submarines were ordered 1/12/1926 in France and represented increased variant of French submarines of Saphir class.

Differed good seaworthiness, but were noisy, oil fuel tanks in an outer hull at the slightest damage leaked and fuel was polluted. Minelaying system of Normand-Funeau was complex and had low reliability. Four TTs took places in the pressure hull, two more out of a pressure hull in aft trainable mount. Double-hulled. Self-sufficiency was 35 days.

Modernizations: 1935, all: - 1 x 1 - 40/39; + 1 x 2 - 13.2/76
