Video: Railgun Blasts an Aerodynamic Round Seven Kilometers Through A Steel Plate

Older railgun projectiles tumbled through the air; this one flies with what can only be called grace

This amazing video, created by Defense Tech, shows the latest test of General Atomics' high-speed railgun. Where earlier attempts have fired ungainly missiles that tumbled end-over-end through the air like "hypersonic bricks," this one uses a sabot round, which flies straight and smoothly for a distance of seven kilometers, AFTER punching through a solid steel plate.
