The heavy cruiser sunken that time was "USS Indianapolis"

That was the ship that had just finished its tasks carrying the heavy parts for the atomic bomb that was dropped on Japan a few days later

And that was also the last USN’s surface ship sunken by the enemy's attack in World War 2

Submarine I-58's last battle result was without the kaitens, only regular topedoes were úed.
