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 "subot" round uses a three stage mechanism that sends a dart-like shell hurdling at amazing speeds - a General Atomics rep claimed over 6.4km, 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 - you might end up paying for it! [DefenseTech]
