Special Operations Command Is Experimenting With Bullets That Shoot Through WaterThere’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.
