America's new 2000lb "quicksink" bomb

Trials show it taking down a merchant ship in under 40 seconds. Film in the link, though as they are sinking a ship one would imagine it has been gutted to remove dangerous items, Asbestos and wiring etc, so the internal structure may have been compromised.

The U.S. Air Force has released new and startling footage of a test of its new "Quicksink" anti-ship bomb kit, which adapts a standard 2,000-pound smart bomb for the purpose of targeting and destroying large vessels. It is an inexpensive alternative to a heavyweight torpedo or an anti-ship missile, which deliver the same effect but at much higher cost.

To create Quicksink, the U.S. Air Force Research Laboratory started out with a GBU-31 Joint Direct Attack Munition (JDAM), the standard guided-bomb tail kit compatible with all American strike aircraft. In its normal configuration, JDAM uses GPS and inertial navigation to maneuver a standard bomb with enough precision to land within about eight feet of the target. Quicksink adds a smart guidance package and sensors onto the bomb's nose, giving it the ability to home in on a ship-shaped target. The bomb drops beside the ship and detonates underwater, breaking the keel with a massive pressure wave without ever actually striking the hull.

The newly-released video shows the perspective of a camera mounted on a target ship. Almost immediately after detonation, the camera flies off its mount, falls to the deck, and is immersed in the water flooding over the vessel's side - emphasizing the extreme rapidity of the sinking. Based on the timeline in the first video released by the Air Force, the stern section of the target ship went under in about 20 seconds, followed by the bow some 17 seconds later.

Thanks, missed that.

Perfecting the art of creating a rapidly expanding hole in the ocean under the middle of a ship.

It's only a little ship - and quite an old one too by the looks, subject to a ton of HE going off adjacently, when stationary. That was always going to end badly.

Whether that guidance package could deal with a more realistic target would be an interesting exercise.

Still useful demo should one wish to sink merchant shipping quickly.

Remembering that real ships are moving targets. I'm sure predictive algorithms are good, but it's not going to be as easy as the demo suggests.

The ROKS Cheonan was taken out by cavitation or something similar.

From Wiki: The explosion might have created a bubble jet that eventually generated an enormous shock wave and caused the ship to break in two.

Interesting that the only competitor mentioned the USAF promo is the MK48 torpedo. No mention of anti-ship missiles, which can be launched from sub, surface, and air platforms.

The spirit of Billy Mitchell lives on!

Ship is less dense than water, hence it floats. Any explosion is going to seek the path of least resistance, which from under a ship is through the ship.

A thing floats when it displaces more water than it weighs. Density has nothing to do with it.

No, it displaces precisely the same amount of water that it weighs. And it can only do that because it is less dense.

You might want to read about it first, before saying how it works.

Both sentences are incorrect!

A bit of open source material about JDAM.

I doubt that they would discuss in open source its effectiveness versus moving targets.

In one of the videos, it shows the targeting sensor

"Quicksink adds a smart guidance package and sensors onto the bomb's nose, giving it the ability to home in on a ship-shaped target. The bomb drops beside the ship and detonates underwater, breaking the keel with a massive pressure wave without ever actually striking the hull."
