*Before Sept. 11, 2001, few in aviation security imagined — and fewer still drilled for — shooting down a hijacked jetliner. Similarly, if a pirated ship with deadly toxic cargo was headed for [a U.S. port], the region’s array of counterterrorism experts have to be ready to sink it in a post-9/11 world. The first line of defense falls to the Coast Guard’s Sea Marshals, who board suspicious and high-interest vessels … Marshals won’t say if there are standing plans to sink a vessel if it becomes a threat, but NORAD has scrambled F-16 air patrols to check out some ships. *
“What if a vessel clearly poses an immediate threat to the United States? That’s where the Navy comes in,” said Lt. Commander Glynn Smith, a spokesman for Coast Guard’s District 11. “We provide homeland maritime security. The Navy’s role is homeland maritime defense.” Smith said the Navy has scrambled jets to watch suspicious ships.
