US nuke sub, troops send Pacific-wide message

A US Navy submarine carrying nuclear-tipped ballistic missiles is visiting Guam for the first time since the late 1980s and US and Japanese troops will practice amphibious landings on Pacific islands.

The submarine USS Pennsylvania (SSBN 735) is making what the Navy formally calls a "scheduled port visit" to the US territory in the Pacific, according to a Navy press statement.

But a US defense official says that both Japanese and South Korean delegations are in Guam at this time and will be offered rare tours of the submarine.
