I'm not exactly sure which torpedo that is in the picture, there are a couple of surface ship launched torps that look similar. I think they are of the Mk-44/46 variety. I am absolutely certain that fish is not a Mk-48. Further Mk-48s do not sink their targets by blowing nice neat holes in the outer casing. They sink their targets by blowing bloody great holes in their pressure hulls. This story broke a week or two ago on the submarine BBSs. Just my opinion, but I consider it one step below "BigFoot Stole Elvis's Brain!" Considering the source, you could make that two steps.

I don't know if it's MK-48s or some other torpedo, but I remember reading about torpedos designed to sink surface ships that used proximity fuses, and they did NOT impact the hull, but would dive down beneath the hull, and explode underneath the ship. The sharp overpressure, and then the sudden vaccuum, would cause the "spine" of the hull to crack, effectively cutting the ship in two pieces.
