News that American warplanes fired depleted-uranium (DU) rounds at Islamic State oil tanker trucks in the Syrian desert in 2015 raises the question of um, why? This specialized cannon ammunition was designed to pierce heavily armored combat vehicles such as tanks and troop carriers, based on the high school physics lesson that the force of a moving object varies directly with its mass and acceleration. Uranium is 70 percent denser than lead, so it packs a more powerful wallop than conventional ammo. (“Depleted” here just means that the DU scavenged from enriching natural uranium for nuclear reactor fuel contains mostly U-238 rather than the coveted fissile isotope U-235, but it is of course still radioactive.) Using DU rounds to hit commercial trucks is like using a monster maul to squash worms.
