Both submarines carried nuclear weapons. Kate Hudson, head of the Campaign for Nuclear Disarmament, said the collision was "the most severe incident involving a nuclear submarine since the sinking of the Kursk, and the first time since the Cold War that two nuclear-armed subs are known to have collided." Information on the collision was not made public until February 16, 2009.Telegraph: British and French Nuclear Submarine Collision... (February 16, 2009)
