In 1964, the Portuguese government ordered the construction of four of this class at the Dubigeòn-Normándie Shipyard to create the 4th Submarine Flotilla.

With the first submarine commissioned on 1 October 1967, the Portuguese Navy started to have a submarine able to operate in both coastal and oceanic zones, especially in the Portuguese exclusive economic zone.

The last Albacora-class submarine in service, NRP Barracuda, made its final mission in 2010. The class was replaced by two Type 209PN/Type 214PN submarines.

gollark: Because Windows bad and legacy stuff.
gollark: I blame... UTF-16, somehow?
gollark: You should check if they're exotic Unicode.
gollark: That would shave off a few % at best.
