Ballistic Missile Submarine

The modern nuclear powered ballistic missile submarine is one of the most complex, and without doubt the single most destructive machine man has ever created. Capable of remaining submersed and invisible for up to six months, then within minutes able to shower any landmass on the planet with multiple independently targetable thermonuclear warheads. Marrying a nearly undetectable launch platform and virtually unstoppable miniaturised warheads reentering the atmosphere at 12,000 mph, each submarine can deliver enough explosive force to destroy an entire continent.
