The Daphné class was a type of diesel-electric patrol submarines built in France between 1958 and 1970 for the French Navy and for export.

History

These submarines were enlarged versions of the Aréthuse class. Eleven were used by France. Boats of this design were sold to several other countries: Pakistan (3), Portugal (4), South Africa (3) and Spain (4). However, two (Eurydice 1970 and Minerve 1968) sank accidentally and brought sales to an end. The cause was eventually considered to have been a faulty snorkel design. The submarines were scrapped in the 1990s and Portugal sold one of its boats to Pakistan. PNS Hangor sank the Indian frigate INS Khukri during the 1971 Indo-Pakistani war. Pakistan has now retired the submarine and is replacing it.

Design features

Besides its eight torpedo tubes forward, this submarine class has four in the stern, which point rearward. All are for torpedoes of the French 550 mm diameter; while the forward tubes hold full-length torpedoes, the stern tubes only shortened ones.

The forward diving planes are located below the midplane of the hull. Unlike those of modern German submarines, which are similarly located, they function by tilting and cannot retract; neither do they fold.
