On of the theories in the Kursk incident suggest that it was sunk by USS Memphis following the collision with USS Toledo. Theory has originally surfaced in 2005 film, but lately allegedly there are some leaks from Russian Navy officers confirming it.
French filmmaker Jean-Michel Carré, in Kursk: a Submarine in Troubled Waters, which aired on 7 January 2005 on French TV channel France 2, alleged that Kursk sank because of a sequence of events triggered by a collision with a US submarine. Carré claimed that Shkval torpedo tests were being observed by two US submarines on duty in the region: USS Toledo and USS Memphis. According to his version, these observations eventually led to a collision between USS Toledo and Kursk. Carré theorized that neither of the subs was seriously damaged in this incident, but the sound of the collision, combined with sounds of loaded torpedo tubes, made the captain of USS Memphis believe that Kursk was preparing an attack on USS Toledo, so he launched a pre-emptive strike against Kursk with a MK-48 torpedo. According to Carré, this attack was successful and was the cause of the powerful explosion within Kursk's hull, sinking the submarine and leaving Memphis and Toledo slightly damaged. Carré claimed that specific damage visible on the Kursk hull was the main evidence of this version, including signs of an initial collision, and a hole left by the torpedo when it entered the Kursk hull. He also claimed that a damaged submarine was sighted leaving the Kursk incident area, and USS Memphis was sighted soon afterwards being repaired in a Norwegian port.

- is there any indication that collision actually happened?
- is there any possibility that it was sunk by Mk-48 fired by USS Memphis?
