Images: Deadly Katrina hits Gulf Coast
Recovery efforts from the devastation of Hurricane Katrina are underway. The U.S. Navy is sending ships to provide relief to the hurricane-ravaged Gulf Coast. The multipurpose amphibious assault ship USS Iwo Jima is one of four ships that will bring six disaster relief teams with amphibious construction equipment, medical personnel, and supplies.
The Safeguard-class rescue and salvage ship USS Grapple is also en route to the Gulf Coast. It was built for salvage, diving, firefighting and heavy lift capabilities. It can add hurricane recovery to its resume.
