A 648-foot government cargo ship with a labyrinth of tubes and valves in its hold should sail within two weeks to destroy some of Syria's chemical weapons.

The cavernous cargo hold of the MV Cape Ray was opened for media tours Thursday along the Elizabeth River in Portsmouth. The Defense Department displayed the two massive treatment units that will neutralize 700 tons of chemical weapons, including mustard gas and Sarin, a form of nerve gas.

Called field deployable hydrolysis systems, the technology has never been tested under conditions at sea.

Frank Kendall is an undersecretary of defense. He said the technology has been used for a decade on U.S. soil, so he said there is "no mystery about the process."
