Air Force Mulls Underground Tunnel Network for Nukes

Would make them harder for enemy to target

The Air Force wants to upgrade its aging nuclear missiles and the hundreds of underground silos that hold them. One idea it's exploring: the construction of a sprawling network of underground subway tunnels to shuttle the missiles around like a mobile doomsday train. As one does.

As first reported by Inside Defense, the Air Force Nuclear Weapons Center will award several study contracts next month worth up to $3 million each to research the idea. A broad agency announcement from the Air Force describes the hair-raising concept, intended to keep the weapons secure through 2075, as a system of tunnels where nuclear missiles are shuttled around on rails or some undefined "trackless" system.

The advantage of the world's deadliest subway: During an atomic holocaust, mobile missiles are harder for an adversary to target than a static silo. Missiles could be positioned at launch holes placed at "regular intervals" along the length of the tunnels.
