Events

 12-01-1943   Completed
 22-09-1943   Having penetrated the anti-submarine nets at the entrance to Kaa Fjord, X7 manoeuvred to pass under the nearby anti-torpedo nets and placed explosive charges under the Tirpitz funnel and after-turret.

On the return journey X7 was hampered by the anti-torpedo nets and had only travelled 400-500 yards from the battleship when the charges exploded. The resulting shock waves severely damaged X7 and rather than compromising the operation by surfacing, the submarine lay on the bottom for over an hour. With the submarine completely out of action, it returned to the surface to face fierce gunfire. The submarine was unable to hold the surface and sank back to the bottom.
