Were the United States to go to war with Russia, both sides could draw on deadly weapons that the world has never seen on a battlefield. On the Russian side, there are new and smaller tactical nuclear weapons. To counter them, the U.S. Army is taking another look at a “devastating” weapon, one first tested by the Air Force and Lawrence Livermore National Laboratory in 2013, the Kinetic Energy Projectile, or KEP, a tungsten-based charge moving at three times the speed of sound that can destroy anything in its path.

“Think of it as a big shotgun shell,” Maj. Gen. William Hix, the Army’s director of strategy, plans & policy, said a few weeks ago at the Booz Allen Hamilton Direct Energy Summit. But unlike a shotgun shell, Hix said, the KEP moves at incredible speeds of “Mach 3 to Mach 6.” Randy Simpson, a weapons programs manager at Lawrence Livermore National Lab, explains that kinetic energy projectiles are warheads that “take advantage of high terminal speeds to deliver much more energy onto a target than the chemical explosives they carry would deliver alone.” FULL REPORT
