Rail guns are still halfway between sci-fi and battlefield, but the armscrafters at General Atomics are still working to improve the futuristic weapon. Instead of launching clunky "bricks," a new, aerodynamic round is being tested. Git ready fer military porn!
The "sabot" round uses a three stage mechanism that sends a dart-like shell hurdling at amazing speeds and distances—a General Atomics rep claimed over four miles, perfectly straight, even after smashing through a steel plate. So hey! Will this weapon system, like most others, probably take forever to develop, and be ungodly expensive? Sure! But it makes for some tantalizing footage. Make sure to enjoy it—you might end up paying for it! [DefenseTech]
