HMS Vanguard and Le Triomphant submarine collision across the seabed". However, a government spokesman said that there "was no compromise to nuclear safety". Hervé Morin, France's Minister of Defence, said that they "face an extremely simple technological problem, which is that these submarines are not detectable". HMS Vanguard and Le Triomphant submarine collision The submarines HMS "Vanguard" and "Triomphant" collided in the Atlantic Ocean in the night between 3–4 February 2009. Both are nuclear-powered ballistic missile submarines. The Royal Navy's and the French Navy's both sustained damage, but no injuries or radioactivity releases were reported. At the time of the collision, both vessels were submerged and, according
Triomphant-class submarine first three boats are to be retrofitted to the M51 missile standard, starting with in 2010, then , and ending with in 2018. In French, these are called "Sous-Marin Nucléaire Lanceur d'Engins de Nouvelle Génération" (English: "Next Generation Device-Launching Nuclear Submarine"), abbreviated as SNLE-NG. They have replaced all of the boats, with the last of those six boats being decommissioned in 2008. These submarines carry 16 submarine-launched ballistic missile launching tubes apiece. This class reportedly produces approximately 1/1000 of the detectable noise of the "Redoutable"-class boats (submarines), and they are ten times more sensitive in detecting other submarines.
