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) which was applied to the fifth (S605 Améthyste) and sixth (S606 Perle) hulls.

The Améthyste and Perle were both longer that the original Rubis, 73.6 metres as compared with 72 metres 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 to 1995.
