France's defence ministry said in a statement, dated 6 February, that Le Triomphant "collided with an immersed object (probably a container)" when coming back from patrolling. On 6 February, France's defence ministry had said that Le Triomphant "collided with an immersed object (probably a container)" when coming back from patrolling, and that the vessel's sonar dome was damaged.
"The sonar dome, at the front, was damaged. This incident did not cause any injuries among the crew and did not threaten the nuclear security at any time," it said. But in a subsequent statement, it admitted that the collision between the two submarines took place.
"The submarine came back by its own means to L'Ile Longue, escorted by a frigate, as it is the usual practice when leaving or coming back." "They briefly came into contact at a very low speed while submerged," the statement added.

"Both navies want quiet areas, deep areas, roughly the same distance from their home ports. So you find these station grounds have got quite a few submarines, not only French and Royal Navy but also from Russia and the United States.""Both navies want quiet areas, deep areas, roughly the same distance from their home ports.
