Galerna (S-71) is an Agosta-class submarine of the Spanish Navy, currently in service. She was built by Bazán at Cartagena, Spain. Galerna was launched on 5 November 1981 and commissioned on 21 January 1983.

The Agosta-class submarine is a class of diesel-electric fast-attack submarine developed and constructed by the French DCNS in 1970s to succeed the Daphné-class submarines.

The submarines have a length of 67 m (219 ft 10 in), a beam of 6 m (19 ft 8 in), and a displacement of 1,500 long tons (1,524 t) surfaced and 1,760 long tons (1,788 t) submerged.

The Galerna is armed with 20 torpedoes of three different types: ECAN L5 MOD4 (against submarines), ECAN F17 MOD1 (against surface ships) and ECAN F17 MOD2 (against both types of target).

The torpedoes are fired from 4 torpedo tubes, which are equipped with a pneumatic system for rapid loading and launching with a low acoustic signature. The same tubes are used to launch magnetic and acoustic-influenced mines of the MCC 23 type, and with minor modifications could fire anti-surface ship missiles.
