Poster Collision between "HMS Vanguard" and "SNLE Le Triomphant"

On the night of February 3-4, 2009, an improbable collision took place in the Atlantic Ocean: the SSBN Le Triomphant and HMS Vanguard collided.

The accident, which fortunately did not make any victim, remains nonetheless spectacular. The two submarines were not able to detect each other, as their acoustic discretion is high.

The visual representation of this event is of course the author's personal interpretation. It seems that the SSBN struck the British submarine from the starboard side, near the missile bay. The French submarine would then have "slipped" under the Vanguard, damaging part of the tower and a diving sail.

Fortunately, the two submersibles were able to return to their respective bases, only later learning the real reason for their collision.
