SOCOM Exploring Under Water Ammunition

FAYETTEVILLE, N.C.— There’s a reason bad guys in spy movies use harpoon guns when they have to fight underwater. Regular bullets lose their deadly momentum when traveling through liquid or other dense substances. U.S. Special Operations Command, or SOCOM, has begun experimenting with new bullets that could allow frogmen to shoot up into enemy boats or helicopter gunners to strafe periscope-depth submarines.

How does it work? The tungsten-tipped CAV-X bullet from Virginia’s DSG Technologies has a nose that creates a small air bubble as it moves through the water. The bubble greatly reduces drag on the bullet, a supercavitation effect that has been part of torpedo design since World War II and is now a feature on some types of boats.

DSG provided bullets to Special Operations Command for testing earlier this month. Odd Leonhardsen, the company’s chief science officer, said the tests will include firing up toward the surface from underwater, and some others he said he wasn’t told about.

SOCOM officials haven’t returned calls for comment.

But the company mounted its own demonstration on Wednesday morning at a shooting range outside Fayetteville, North Carolina. Using a Colt AR-15, a company employee fired a CAV-X bullet through 13 blocks of ballistic gelatin, each 1.3 feet long — the kind the FBI uses in testing. The cubes, a bit denser than water, stand in for human flesh. A normal bullet will penetrate just a couple of cubes.

Interesting development though I’m not sure how badly this is needed. You may or may not be aware of the USSR’s solution to this requirement.

  1. Elephant hunters have been playing with cavitating bullets for well over a decade… they do work, goes the reports. We all know the old story that it’s safe to shoot down into a swimming pool with anything, even a .50 BMG, and not damage the bottom of the pool. Not so with these.
