The U.S. military on August 31, 2005, added Navy ships, including two helicopter assault vessels and the hospital ship Comfort, and dozens of helicopters to a massive relief effort in the wake of killer Hurricane Katrina. The military's Northern Command said the Comfort, with 12 operating rooms and 1,000 beds, would soon depart Baltimore for a weeklong trip to the area, and the helicopter carrier USS Bataan and another warship were already conducting rescue missions from off the Louisiana and Mississippi coasts.
