Images from the Navy PowerPoint presentation: THE AWESOME POWER OF THE SUBMARINE LAUNCHED MARK-48 TORPEDO

On Monday, June 14, 1999, the Australian Collins class submarine HMAS Farncomb fired a Mark-48 war-shot torpedo at the 28-year-old former Destroyer Escort Torrens. The firing was part of the Collins class trials requirements and was designed to validate the submarine's combat system. The submerged Farncomb fired the Mark-48 torpedo at the stationary hulk of the 2700-ton Destroyer Escort from over the horizon. The plume of water and fragments shot some 150 meters skyward as the blast of the torpedo cut the ship in two. The stern section sank rapidly after the torpedo hit; the bow section remained afloat, but sank sometime later.

The torpedo warhead contains explosive power equivalent to approximately 1200 pounds of TNT. This explosive power is maximized when the warhead detonates below the keel of the target ship, as opposed to striking it directly. When the detonation occurs below the keel, the resulting pressure wave of the explosion "lifts" the ship and can break its keel in the process. As the ship "settles" it is then seemingly hit by a second detonation as the explosion itself rips through the area of the blast. This combined effect often breaks smaller targets in half and can severely disable larger vessels.

The Mark-48 torpedo used in this test is a variation of the MK-48 ADCAP (Advanced Capability) torpedo developed for the United States Navy.
