A digital drawing of the nuclear french attack submarine "Emeraude" (Rubis class) in dry dock.
The Ruby Class is a class of six Nuclear Attack Submarines launched in the early 1980s, and still in service today. Their mission: submarine warfare, escorting convoys (SSBN, aircraft carriers, etc.) and electronic intelligence.
Replacing the classic Agosta-type submarines, the Rubis are the smallest nuclear submersibles in the world, thanks to a particularly compact nuclear boiler. Proof of French know-how, both in design and maintenance, they are still in active service even though the first of the serie will soon be approaching 40 years.
The Emeraude, here represented on its tin line, is the fourth in the series. Launched in 1986, he was admitted to active service in 1988. It was the first of the 6 ANS to be developed directly in an improved version (bow in "albacore" shape, enveloping bridge and technical improvements). The other 4 first S.N.A. will be recast to this standard.
The Emeraude suffered a very serious accident during its career: on March 30, 1994, during an exercise, a steam leak killed 11 crew members in the turbo-alternator compartment. This is the deadliest accident to date on a French nuclear submarine.
In a different register, the Emeraude actively participated in the search for the black boxes of flight AF 447 Air France which crashed on June 1, 2009.
These submarines, nearly 74 meters long and 2,400 tonnes, carry 68 crew members for missions sometimes longer than three months. They are equipped with wire-guided F17 torpedoes, mines and EXOCET SM39 missiles. The S.N.A. Rubies can also deploy commando teams as close as possible to the coast.
