Although the Rubis class belonged to the same generation as the Redoutable, due to President Charles De Gaulle's insistence on acquiring a nuclear deterrent for France, the Rubis program was started only in 1974, after the ballistic missile submarine program. The first Rubis hull was laid down in December 1976 and launched in 1979.

AMETHYSTE rebuild:
The initial design of the Rubis proved to be problematic with unexpectedly high noise levels. This led to the Améthyste silencing program (AMÉlioration Tactique HYdrodynamique Silence Transmission Ecoute, literally Silent Acoustic Transmission Tactical Hydrodynamic Improvement) which was applied to the fifth (S605 Améthyste) and sixth (S606 Perle) hulls.

Améthyste and Perle were both longer that the original Rubis, 73.6 metres (241 ft) as compared with 72 metres (236 ft) and the program included upgrades to the sonar, reshaping of the hull form and bow to improve silencing and additional upgrades of the electronics. With the upgrades tested and proven, the original 4 boats were rebuilt to the same standards between 1989 and 1995.

Design:
They have a central computer system for submarine detection, processing of information, and firing of weapons. The hull is made of 80 HLES high elasticity steel. The sonar dome and sail are made of composite materials. The submarines have two crews, "Blue" and "Red", who man the ships every three months in turn.

They will be succeeded by the 2nd-generation Barracuda class.
