|1.61k||Lapon (SS-260), at left and Raton (SS-270) tied up along side each other at Fremantle, Western Australia, June 1944. The reason for the unfriendly looks are as follows: On 27 May, Raton's ship's log reported: "0615 (H) Ship shaken up considerably by either two underwater explosions or by striking submerged object. People in forward torpedo room thought we had struck something or had been struck by something." This turned out to be 2 torpedoes fired by Lapon. Lapon was looking for a Japanese submarine passing through the area and mistook Raton for that enemy sub. The Commanding officer checked fire on the second set of torpedoes realizing he wasn't shooting at the enemy. Later dry-dock inspection of Raton showed dents where the torpedoes hit. This is the only known friendly fire incident in World War II between two submarines.||Image scanned from United States Submarine Operation in World War II by Theodore Roscoe via Robert Hurst|
