Trident A-sub going through its paces

The USS Ohio -- the nation's first Trident submarine -- headed into the North Atlantic for sea trials that have captured the attention of a Soviet spy ship. The Navy's mightiest undersea vessel ever was escorted by tugs from its construction berth at the electric Boat Division of General Dynamics toward Block Island Sound and the open Atlantic as helicopters hovered overheard. The Navy said Adm. Hyman G. Rickover, the 81-year-old pioneering supporter of the nuclear Navy, would direct the first sea trial of the Ohio, which is over a year behind its scheduled delivery to the Navy.
