The Pentagon's fleet of ships, aircraft and other military resources to help the tsunami relief effort is costing about $6 million a day.
That covers a U.S. contingent of about 13,000 military personnel, most of them aboard 17 Navy ships in the region. It's possibly the largest humanitarian aid contribution in history.
The latest ship to join the effort is a hospital ship that set sail last night from San Diego. It's staffed to support 250 patient beds but could be expanded to a thousand.
The biggest share of the cost is for the USS "Abraham Lincoln" battle group, the first Navy group to arrive on the scene last week.
