An Ohio-class submarine carries 20 Trident II D5 missiles, each of which can deliver up to eight nuclear warheads to targets as far as 12,000 km (7,500 miles) away.

Let me get this straight. Do these missiles split into 8 individual warheads that can hit individual targets? Or do they just pack 8 warheads together for bigger boom? Or is it more of a cluster bomb kind of deal?

On one hand, cool. On the other, especially considering what's hot in the movies recently, bloody hell that's a bit too many bombs, isn't it?
